Wraith King
* E.M.P. allows Invoker to burn Wraith King's mana to prevent 
Reincarnation from triggering (only until Wraith King gets his Aghanim's Shard).
* Ice Wall and Cold Snap are particularly crippling for Wraith King as they allow to kite him very effectively, preventing him from dealing melee attack damage.
Additional:
* Invoker can drain Wraith King's mana with 
E.M.P., preventing him from reincarnating unless Wraith King has his Aghanim's Shard.
* Even if Wraith King survives and reincarnates, Invoker still has an arsenal of spells to lockdown Wraith King, including an easily setup 
Ice Wall.
* 
Tornado applies an area dispel to clear skeletons.
Primal Beast
* Invoker's numerous area-of-effect abilities can interrupt Primal Beast, especially while he is in the middle of a team fight, where Primal Beast thrives. (Tornado, 
Cold Snap, and Ice Wall all help to disable Primal Beast and control him from a distance.
* E.M.P. disintegrates Primal Beast's low mana pool.
* However, Invoker is quite a slow-paced hero and not particularly known for being survivable against a rampaging Primal Beast with 
Black King Bar.
Wraith King
* Heroes with area dispel can kill multiple skeletons at once: 
Brewmaster, 
Oracle.
Primal Beast
* Oracle can negate and shut down Primal Beast simply with Fate's Edict, especially in the early game, as a majority of his damage-dealing spells are magic.
* Oracle can interrupt Primal Beast's 
Onslaught charge with a well-timed Fortune's End.
* Primal Beast's lethal burst damage combos can be further stalled with False Promise; combined with Fate's Edict and regen from Purifying Flames, Oracle can even completely negate Primal Beast's offense.
Additional:
* 
Fate's Edict completely negates all of Primal Beast's major damage-dealing spells in the early game and can render Primal Beast useless when cast on a target he is focusing, or in Oracle's defense against Primal Beast himself.
* 
Fortune's End keeps Primal Beast in place, especially while trampling or in the middle of an Onslaught charge.
* 
False Promise can interrupt Primal Beast's abilities, as well as further delay Primal Beast from dealing lethal burst damage. In combination with Fortune's End, Oracle can potentially save an ally from Primal Beast's spell combos.
Wraith King
* Heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him thanks to his 
Atrophy Aura, and will also be unable to ambush Underlord and his team if Underlord chooses to use 
Fiend's Gate to get to a designated point of the map: 
Phantom Assassin, 
Terrorblade, 
Troll Warlord, 
Drow Ranger, 
Phantom Lancer, 
Chaos Knight, 
Sven, 
Wraith King, 
Bounty Hunter, 
Alchemist, 
Templar Assassin, 
Nyx Assassin, 
Bane.
Primal Beast
* 
Pit of Malice is very good at preventing Primal Beast from entering the fight and stopping Trample damage at all stages of the game.
Wraith King
* Sanity's Eclipse does massive damage to Wraith King who naturally has a low mana pool and typically doesn't build items to increase it.
* 
Wraithfire Blast's slow projectile speed makes it easy to avoid using Astral Imprisonment.
Primal Beast
* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as Troll Warlord, 
Lone Druid and 
Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.
Wraith King
* Wraith King has a very low mana pool and is extremely dependant on it to cast his high mana cost abilities, so 
Mana Drain will make him struggle way too hard, even not being able to active his passive ability Reincarnation, forcing the Wraith King to buy 
Aghanim's Shard as soon as possible.
* Althought Wraith King may not be as fragile to struggle against 
Lion's damage, it's much easier to disable and harass him, as Wraith King doesn't have any mobility at all, his only gap closer being Wraithfire Blast which costs too much mana for his mana pool, and may only affect one target.
Additional:
* While not being able to confront Wraith King by himself, Lion's Mana Drain helps in draining Wraith King's mana, preventing him from reincarnating unless he has his Aghanim's Shard.
* Lion's 
Earth Spike and 
Hex provide decent lockdown against Wraith King as well, preventing the latter from benefiting from Vampiric Spirit bonuses.
Primal Beast
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as 
Shadow Shaman, Lion, Nyx Assassin.
Wraith King
* Many physical-only single-target heroes like 
Lifestealer, Sven, Wraith King, Phantom Assassin, Templar Assassin can have their damage mitigated by Cold Embrace.
Primal Beast
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: 
Lich, 
Ogre Magi, 
Winter Wyvern.
Primal Beast
* 
Borrowed Time allows him to both exit his stuns prematurely and turn Trample into healing for himself. His Aghanim Scepter only prevents the automation of the spell, Abaddon himself can still manually activate it.
* 
Aphotic Shield will immediately debuff any stuns Primal Beast has put on allies but won't stop him from being stunned if casted on Abaddon.
Primal Beast
* 
Glimpse can prevent Primal Beast from initiating for most of the game with Onslaught.
* While 
Static Storm is not much of a threat in terms of damage, it does prevent Primal Beast from casting any spells for a long period of time if also trapped in 
Kinetic Field.
* Overall, Disruptor forces Primal Beast to buy a Black King Bar much earlier than he might like but becomes a major threat to Disruptor once he does.
Primal Beast
* Primal Beast is disarmed during Trample so will be unable to destroy a 
Supernova no matter how close it is to him.
* The same ability can also be used to save allies with the help of an 
Aghanim's Scepter.
* 
Sun Ray will do thousands of damage to Primal Beast if surviving a full channel time due to his high health scaling for the ability.
* 
Icarus Dive is a fantastic way to escape Primal Beast after he has used Onslaught.
* Phoenix has a naturally very high health pool making it hard for Primal Beast to deal with him with his magical damage.
Primal Beast
* The ensnare from melee 
Berserker's Rage can prevent Primal Beast from dealing further Trample damage and can allow Troll Warlord to relentlessly build 
Fervor on him.
* 
Whirling Axes (Ranged) can slow down Primal Beast while trampling and allow Troll Warlord to better control him from range.
* 
Whirling Axes (Melee) can blind Primal Beast if he attempts to auto-attack Troll Warlord after a fully charged Uproar.
* 
Battle Trance will make Primal Beast a sitting duck should he be rooted and attacked to death.
Wraith King
* Riki is a natural 
Diffusal Blade carrier, and it doesn't help that he's easily capable of sneaking up on Wraith King due to 
Cloak and Dagger.
* Riki can use 
Smoke Screen on top of Wraith King as he is reincarnating, making him a sitting duck for his second life. In addition, the blind prevents Wraith King from landing critical hits from Mortal Strike.
* Wraithfire Blast is quite predictable, and if Riki can react fast, he will disjoint it with 
Tricks of the Trade. There is also a chance he will become invisible again as the projectile travels, disjointing it.
Primal Beast
* 
Time Walk makes it impossible for Primal Beast to stay on top of Faceless Void with his abilities and allows him to heal burst damage dealt to him.
* Once Faceless Void has an Aghanim's Shard, Onslaught can be easily escaped. He could also choose to get a lower cooldown on Time Walk, making it even harder for Primal Beast to catch him in fights or stop his initiations.
* 
Time Dilation will make Primal Beast useless for an extended time after casting his abilities if he does not have a dispel.
* 
Chronosphere has many uses such as stopping Primal Beast from casting abilities on him or allies or even on a teammate, since Primal Beast has no way to assist allies trapped within the sphere.
Wraith King
* Mana Break quickly eats away at Wraith King's small mana pool, preventing Reincarnation from triggering.
* Wraith King has no innate mobility. Even with 
Blink Dagger, Wraith King is easily kited by Blink.
* Anti-Mage can farm much more quickly than Wraith King, allowing Anti-Mage to overpower Wraith King once a significant farm advantage is established.
Additional:
* 
Mana Break can prevent Wraith King from reincarnating unless Wraith King has his Aghanim's Shard that removes the mana cost from Reincarnation.
* With 
Manta Style, his mana burning will triple because illusions can also use Mana Break.
* Wraithfire Blast is quite predictable, and if Anti-Mage can react fast enough, he will be able to disjoint it with 
Blink or reflect it back with 
Counterspell.
Primal Beast
* 
Soulbind prevents Primal Beast from being able to use Onslaught or his abilities to great effect for a lengthy amount of time.
* 
Phantom's Embrace is very difficult for Primal Beast to remove due to his slow attack speed and Trample preventing him from attacking.
Wraith King
* Diffusal Blade lets Phantom Lancer drain Wraith King's mana, preventing Reincarnation from triggering until he buys an Aghanim's Shard.
* Wraith King is bad against illusions-based heroes, as Wraithfire Blast is his only single-target disable and can get overwhelmed easily.
* 
Doppelganger can disjoint Wraithfire Blast.
Additional:
* Doppelganger disjoints Wraithfire Blast.
* Wraith King is not good at handling illusion-based heroes, as his only disable is single-target.
* Phantom Lancer tends to get Diffusal Blade, leaving Wraith King no mana to reincarnate until he has Aghanim's Shard.
Wraith King
* Wraith King's lack of area of effect spells makes him easily overwhelmed by Beastmaster's summons.
Wraith King
* Heroes who rely on basic attacks will suffer from Laser: Phantom Assassin, Wraith King, 
Huskar.
Primal Beast
* Heroes who can do scaling health damage to Primal Beast are very threatening for the hero. Such as: 
Phoenix, 
Tinker etc.
Primal Beast
* Heroes with unorthodox escapes will struggle against Primal Beast, such as 
Nature's Prophet, Tinker, and Templar Assassin.
Wraith King
* 
Clinkz, 
Sniper, Lone Druid, Troll Warlord, 
Legion Commander and Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.
Primal Beast
* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as Troll Warlord, Lone Druid and Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.
Wraith King
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: 
Beastmaster, 
Broodmother, 
Enigma, Nature's Prophet, 
Visage, 
Warlock, Wraith King.
Primal Beast
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich, Ogre Magi, Winter Wyvern.
Wraith King
* Heroes with summons and illusions can find themselves easily bested by Lina, like Broodmother, Nature's Prophet, 
Chen, Terrorblade, 
Naga Siren, Visage, Wraith King, 
Lycan, Phantom Lancer, Shadow Shaman.
Wraith King
* 
Meepo has a better advantage in farm with 
Divided We Stand, as well as having a higher attack speed due to his tendency to build items that give attributes. In addition, Wraithfire Blast stuns only one target, and choosing to engage one Meepo will most certainly mean engaging them all.
Primal Beast
* Any ganking heavy support can be a big problem for Primal Beast, such as: 
Earth Spirit, 
Grimstroke before he has a Black King Bar.
Primal Beast
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich, Ogre Magi, Winter Wyvern.
Wraith King
* Heroes with area dispel can kill multiple skeletons at once: Brewmaster, Oracle.
Primal Beast
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.
Wraith King
* Jakiro's area-of-effect abilities make him strong against heroes who rely on illusions and summons: Terrorblade, Naga Siren Chaos Knight, Phantom Lancer, Broodmother, Nature's Prophet, Lycan, Wraith King, Visage.
Wraith King
* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.
Primal Beast
* Primal Beast really suffers against supports he cannot bully in the lane: this includes 
Dazzle, 
Shadow Demon and 
Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
Wraith King
* Heroes that lack burst damage will have a difficult time taking down Monkey King, and fare badly against Jingu Mastery: Legion Commander, Lifestealer, 
Weaver, Wraith King
Additional:
* Wraith King has no ability to destroy trees from 
Tree Dance.
* Monkey King tends to get Diffusal Blade, leaving Wraith King no mana to reincarnate unless Wraith King has his Aghanim's Shard.
* A reincarnated Wraith King is an ideal target for 
Wukong's Command.
Primal Beast
* 
Power Cogs keeps Primal Beast pinned down, preventing him from doing damage with Trample. Primal Beast's slow attack speed makes it hard for him to break the cogs and get away. In addition, Power Cogs' knockback is forced movement and thus will intercept Primal Beast's Onslaught if placed well.
* 
Battery Assault on a lone Primal Beast in the early game effectively keeps him from winding up Onslaught or basic attacking.
* 
Rocket Flare and 
Jetpack (from purchasing Aghanim's Shard) give Clockwerk many options to scout for Primal Beast, whose kit benefits greatly from ambushing.
Wraith King
* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying 
Dagon and 
Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage: 
Faceless Void, Terrorblade, 
Ursa, Weaver, Broodmother, 
Slark, 
Abaddon, Wraith King, Lifestealer.
Wraith King
* Even if Wraith King dies after Magnus disables him, Magnus' entire team will be slowed and vulnerable for counter-initiation.
Primal Beast
* Magnus is not tanky and struggles against burst damage, something Primal Beast excels at in the early-to-mid game. Primal Beast is also able to out-damage Magnus's 
Empower and can even contribute to his Uproar stacks.
* Using 
Skewer to drag Primal Beast while he is trampling will count as movement and will trigger a rapid number of slams, which could prove lethal to Magnus.
Wraith King
* Wraithfire Blast cancels 
Death Ward in decent range.
* Death Ward is meaningless while Reincarnation is off cooldown.
* Vampiric Aura can out-heal the {tooltip:DoT|Damage over Time} from 
Maledict.
Primal Beast
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like 
Witch Doctor and 
Omniknight should play very cautiously alone...
Wraith King
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Primal Beast
* Phantom Assassin is known to be weak against bursts of magical damage, something Primal Beast excels at from the beginning of the game. He can use this to his advantage by constantly hunting Phantom Assassin down, especially if she is left alone to farm.
* Primal Beast is a good carrier of Ethereal Blade, 
Vanguard and 
Shiva's Guard all of which are very good against 
Coup de Grace and 
Phantom Strike.
* Even though Primal Beast does a lot of physical damage early on, later once 
Blur becomes more potent, she may find herself being overwhelmed by Trample and Onslaught instead.
* Primal Beast's ultimate goes through spell immunity and his level 25 talent makes it even more devistating against Phantom Assassin.
* Primal Beast can dispel 
Stifling Dagger and any attack modifers it applies with his left level 15 talent.
Wraith King
* Heroes who rely on passive abilities and attacks, such as Drow Ranger, Wraith King, and Lone Druid, can render Silencer useless. But remember that a smart Silencer will most likely buy 
Silver Edge to counter this if he is played as carry.
Primal Beast
* Any hero with low mobility and max healthsuch as 
Silencer, 
Crystal Maiden etc.
Wraith King
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan, Wraith King.
Primal Beast
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: 
Spirit Breaker, 
Gyrocopter, 
Leshrac
Primal Beast
* 
Pierce the Veil does not prevent Primal Beast from using any of his spells to their fullest and is one of the few heroes that can disable her during her ultimate and a common Black King Bar purchase. She will also likely be fatal to herself if Primal Beast has a 
Blade Mail active.
* 
Gunslinger will be disabled if Primal Beast buys an Aghanim's Scepter.
Wraith King
* Wraith King's skeletons from 
Vampiric Spirit keeps the choke points and rune spawns safe from Proximity Mines.
* Wraith King is not afraid to go into a field of Proximity Mines, wherever he goes as long as Reincarnation is off cooldown .
Additional:
* Wraith King is not afraid to walk into mines, whenever he goes with his Reincarnation ready.
Wraith King
* Wraith King has three passive abilities and only a single active ability, so Doom does not hinder him significantly.
* Doom expires upon death, so it is effectively removed after Reincarnation activates.
Additional:
* Even if he is 
Doomed, Wraith King can tear down Doom with physical attacks, and can still reincarnate as long as it is off-cooldown.
Wraith King
* While Reincarnation is off cooldown, Poison Nova poses less of a threat as Wraith King will return with all debuffs cleared.
* Vampiric Spirit can out-heal the slow {tooltip:DoT|Damage over Time} from Poison Sting.
Primal Beast
* 
Sprout gets destroyed by Trample and Onslaught.
Wraith King
* Waning Rift's silence is almost completely worthless against Wraith King, due to him having only 1 active ability.
* Wraith King's only active ability, Wraithfire Blast, is strong against Puck if it hits, because it applies a damage over time on top of stunning and doing impact damage, disabling Puck for a while, and Blink Dagger for even longer. It is very important to avoid getting hit by this spell when playing against Wraith King.
* Even if Puck succeeds to burst down Wraith King, Reincarnation will ensure that Wraith King can fight back against him while leaving Puck exhausted and nearly unable to defend itself against Wraith King. And to make things worse, Puck is not a common Diffusal Blade nor 
Disperser wielder to counter this problem at all.
Primal Beast
* 
Dispersion reduces damage based on a percentage, which is very minimal against large amounts of small instances of damage such as Trample. It reduces each tick by about 14 at the maximum level, which is very small.
* 
Desolate is never a threat to Primal Beast due to his large health pool and Uproar is still out-damaging the ability.
* Onslaught can allow Primal Beast to chase Spectre fleeing with 
Spectral Dagger, as both skills phase through trees and terrain.
* Primal Beast can also dispel Spectral Dagger's slow with his left level 15 talent, making it completely useless against him.
* Primal Beast excels at early aggression, pushing weak carries out of lane and farming areas he wants to control. Overall just not a pleasant matchup for Spectre.
* Should Primal Beast buy an Aghanim's Scepter he can also break both passive abilities.
Primal Beast
* Onslaught prevents all of Razor's abilities from being effective against him, especially in the laning stage.
Primal Beast
* Since Primal Beast is highly mobile with Onslaught alone, he will be difficult to catch with both 
Cold Feet and 
Ice Blast.
* Ice Blast is less effective due to Primal Beast's massive health pool and resistance to taking damage.
* While 
Chilling Touch can be used to slow Primal Beast briefly, it is not enough to beat him back, and can also contribute to his Uproar stacks.
* Primal Beast has a dispel talent at level 15 that will remove Cold Feet immediately when Uproar is used.
Wraith King
* In the early-mid game, Skywrath consistently needs to use his entire mana pool to kill a hero, but Wraith King's Reincarnation allows him to finish off Skywrath after the first death, as Skywrath Mage will have likely expended all his mana.
Wraith King
* Illusion and heroes with summons are difficult to kill with Chen's single-target offensive spells: Terrorblade, Phantom Lancer, Chaos Knight, Broodmother, Naga Siren, Lycan, Visage, Beastmaster, Warlock, Wraith King. And even though Chen can convert enemy summons with Holy Persuasion, their much greater numbers will often overwhelm Chen and his creeps.
Wraith King
* Durable heroes can stand against Tusk during 1v1: 
Axe, 
Dragon Knight, 
Night Stalker, 
Centaur Warrunner, Wraith King and more.
Primal Beast
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac
Wraith King
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Primal Beast
* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.
Primal Beast
* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: 
Primal Beast, Axe, Centaur Warrunner.
Primal Beast
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac
Wraith King
* Heroes with both illusions and summons, for Io has nothing to deal with multiple enemies at once outside from Spirits's weak area-of-effect: Beastmaster, Broodmother, Chaos Knight, Lycan, Naga Siren, Nature's Prophet, Phantom Lancer, Shadow Shaman, Terrorblade, Visage, Warlock, Wraith King.
Wraith King
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, 
Tiny, Wraith King, Ogre Magi.
Wraith King
* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and Wraith King to heroes with quick escape mechanisms like 
Anti-Mage and 
Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.
Primal Beast
* Special mention to Lifestealer who can use 
Rage to prevent Trample damage, but Primal Beast's ultimate can still be casted during the spell.
Wraith King
* Wraith King's Reincarnation allows him to severely punish Legion Commander after he revives, as her abilities are on cooldown. Legion Commander is still awarded a Duel win if Wraith King reincarnates.
Additional:
* Wraith King makes a poor 
Duel target, as he can be already quite hard to bring down once, and then you have to worry about his second life.
* However, even if Legion Commander does win the duel when Reincarnation is off cooldown, she still receives the permanent victory damage bonus because taking down Wraith King's first life still counts as a "kill".
Primal Beast
* Long lockdown is a great way to deal with Axe to prevent Berserker's Call from being used, heroes such as Legion Commander, Beastmaster and Primal Beast are good examples of this.
Additional:
* 
Berserker's Call will be a stun for Primal Beast and not much else due to Trample making him unable to attack.
* 
Battle Hunger is neglitable because Primal Beast has a much bigger health than Axe, so he does not need to fear being slowed, or his other abilities including 
Counter Helix or even a Blade Mail.
* Getting Primal Beast low enough to use a successful 
Culling Blade can be very difficult due to his massive health advantage over most heroes.
* Not ability related but Primal Beast does not need to fear Axe in lane, as Trample, combined with Uproar and Onslaught will do a ton of damage even if Axe has a Vanguard.
Primal Beast
* Hard carries who just want to farm and be left alone will not appreciate Primal Beast, heroes such as 
Medusa, Drow Ranger...
Primal Beast
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and Omniknight should play very cautiously alone...
Wraith King
* Melee heroes who may struggle to get close to Sniper: Wraith King, 
Kunkka, 
Doom, 
Tidehunter, 
Underlord, Troll Warlord, and etc.
Primal Beast
* Primal Beast is one of Sniper's greatest counters, as he has no real means of escape and is very squishy, especially in the early game. Sniper's potshots and 
Shrapnel can contribute to Primal Beast's Uproar and further make him tankier than he already is. Onslaught allows him to close the gap on Sniper at his own volition, and Trample can deal serious damage to his meager health pool.
Wraith King
* Heroes who rely on physical damage are easily negated by Ghost Shroud: Phantom Assassin, Wraith King, 
Juggernaut.
Wraith King
* Using Reaper's Scythe against Wraith King is a bad idea for Necrophos as his Reincarnation can waste it. And when upgraded with Aghanim's Scepter it can delay the deaths of allies.
Additional:
* 
Reaper's Scythe can't kill Wraith King while Reincarnation is off cooldown
* In the laning stage Vampiric Spirit can out-heal the slow {tooltip:DoT|Damage over Time} from 
Heartstopper Aura.
Wraith King
* Heroes who are reliant on physical damage will be nullified by Decrepify: 
Riki, Wraith King, Juggernaut.
Primal Beast
* Primal Beast has multiple ways to cancel 
Life Drain very quickly.
* Pugna has a very low strength gain and as a support does not have much gold to buy health items, making him vulnerable to Primal Beast's onslaught of magical damage.
* Ironically, 
Decrepify actually just increases Primal Beast's damage on the targeted ally if Trample is activated. However, it can be used to slow him down and prevent any further Trample damage.
Wraith King
* Melee heroes with low mobility can be kited and killed by Viper: 
Treant Protector, Kunkka, Alchemist, Troll Warlord, Wraith King, Tiny, Sven.
Wraith King
* Viper's 
Nethertoxin cannot disable Reincarnation, which could put him in disadvantage against Wraith King if his whole team is with him.
* In addition, Viper doesn't like buying Diffusal Blade, which is the only item that can help him against Wraith King.
* Wraith King's high burst damage allows him to kill Viper before being killed.
Primal Beast
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle, Shadow Demon and Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
Wraith King
* Shadow Demon's Demonic Purge with Aghanim's Scepter cannot break Reincarnation, which could put him in a disadvantage against Wraith King if his whole team is with him.
* Vampiric Spirit can out-heal the damage from Shadow Demon's abilities.
* However, Wraith King is a single-target hero, so he cannot deal with Disruption illusions.
Primal Beast
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.
Wraith King
* Reincarnation allows Wraith King to survive Shadow Shaman's initial chain of disables and Serpent Ward attacks.
* Short cooldown of Wraithfire Blast is ideal for interrupting Shackles.
Wraith King
* Terrorblade has very high armor gain, which helps him against Wraith King's physical damage.
* Wraith King is not good against illusion-based heroes as he has no AoE form abilities to deal with Terrorblade's Illusions.
* Terrorblade is a common Manta Style and Diffusal Blade carrier to help deal with Reincarnation before Wraith King has Aghanim's Shard.
* A Reincarnated Wraith King is a good setup for Sunder if Terrorblade's health is low enough.
Additional:
* Wraith King has no form of AoE to clear Terrorblade's illusions.
* Terrorblade is a common Manta Style and Diffusal Blade carrier.
* Terrorblade has very high armor, which helps against Wraith King's physical-only damage.
* A reincarnated Wraith King is an ideal target for 
Sunder if Terrorblade's health is low.
Primal Beast
* Terrorblade has no stun and is vulnerable to Primal Beast's spell comboes due to his low health points in the laning stage and mid game.
* 
Reflection can be dispelled using Primal Beast's level 15 left talent.
* Sunder is the only real threat Terrorblade has against Primal Beast but he may die before he can even use it.
Wraith King
* Heroes who can delivers a big chunk of damage in few hits will find themselves struggle against Templar Assassin's Refraction: Sven, Phantom Assassin, Ursa, Wraith King, Lifestealer
Primal Beast
* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like 
Keeper of the Light, 
Luna, Templar Assassin...
Wraith King
* Heroes with summons and illusions such as Broodmother and Naga Siren, are ill-suited for Wraith King to fight, as he has no source of waveclear.
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.
Wraith King
* Phantasm gives Chaos Knight a significant advantage against single-target damage dealers: Lifestealer, Wraith King, Night Stalker, Troll Warlord.
Additional:
* Wraith King has no form of AoE to clear Chaos Knight's illusions from 
Phantasm.
* Wraith King is very vulnerable if he reincarnates in the middle of his illusions.
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.
Wraith King
* Heroes which rely exclusively on right clicks will struggle somewhat against Blinding Light: Phantom Assassin, Wraith King, Medusa
Primal Beast
* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like Keeper of the Light, Luna, Templar Assassin...
Wraith King
* A hero that 
Rubick cannot reliably kill in most cases, Wraith King is deceptively vulnerable to Rubick in teamfights.
* Rubick can kite Wraith King by casting 
Telekinesis should Rubick stays alive after first wave of skirmishes.
* {{A:Fade Bolt|Rubick} negates damage from Wraith King's skeletons.
* Wraithfire Blast is a spell very easy to stolen even for new Rubick players if Wraith King is on the other side.
* A 2 second stun with a 8 second cooldown (6 second with Rubick's Level 15 talent -25% Stolen Spells Cooldown, as of 7.31c) is already far enough to lockdown Wraith King to a crawl, as he does not have much mobility on his own and can be easily targeted.
* Reincarnation may sound insurmountable, but the extra 3 second delay already grant about half the cooldown duration for a stolen Wraithfire Blast.
* Rubick has sufficient mana pool to cast Wraithfire Blast multiple times.
* Although not the best option, Vampiric Spirit can be casted after Rubick gained enough last hits to summon skeletons for pushing and farming.
Wraith King
* Wraith King abilities are mostly passive making 
Spell Steal meaningless.
* This can also mean that Rubick's Spell Steal used on Wraith King guarantees him a stun spell.
* Rubick's lack of mobility & low health pool is easily tear down by Wraith King physical attacks.
Wraith King
* Even though Wraith King can easily get a chance to retaliate with Reincarnation after Luna uses 
Eclipse against him, smart Luna can also turn Reincarnation against him by using Eclipse right after Reincarnation triggers and gets on cooldown, giving Luna an element of surprise she can use against Wraith King.
* 
Moon Glaives can be used to clear the waves of Wraith King's skeleton warriors summoned from Vampiric Spirit.
Additional:
* Even though Wraith King can easily get a chance to retaliate with Reincarnation after Luna uses Eclipse against him, smart Luna can also turn Reincarnation against him by using Eclipse right after Reincarnation triggers and gets on cooldown, giving Luna an element of surprise she can use against Wraith King.
* Moon Glaives can be used to clear the waves of Wraith King's skeleton warriors summoned from Vampiric Spirit.

* Primal Beast has a massive healthpool making it very difficult to get through it with a nuke such as Eclipse or 
Lucent Beam.
* Primal Beast is faster than Luna, as one of her main ways to escape danger, is very problematic for her in the laning stage especially.
* His ultimate goes through debuff immunity, making Luna's Black King Bar less effective.
* Primal Beast commonly buys Blade Mail which is a big problem for a single target bursting hero like Luna.
Wraith King
* 
Dark Pact, if timed correctly, can dispel Wraithfire Blast's stun and slow.
* Since Wraith King has a lot of health and multiple lives, Slark can keep gaining 
Essence Shift stacks, increasing armor, damage, and attack speed and can beat down Wraith King twice.
* Slark sometimes carries Diffusal Blade to burn mana as an attempt to shut down Reincarnation.
* Because Wraith King has no AoE abilities, 
Shadow Dance is particularly useful against Wraith King.
Primal Beast
* Dark Pact, Shadow Dance and 
Depth Shroud will do nothing against Onslaught and Trample, as they are both ground area-of-effect spells.
* Primal Beast has a gigantic hitbox, which could be difficult for Slark to escape with 
Pounce should Primal Beast choose to block him. Pounce also does not completely prevent Primal Beast from trampling offensively, as he still has some room to move.
* Primal Beast has a huge health pool making it difficult to shed it with Essence Shift and may allow Primal Beast to build Uproar stacks against him very rapidly.
* If Primal Beast buys an Aghanim's Scepter he can also break Essence Shift from working on attacks which is a big part of Slark's damage output.
Primal Beast
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle, Shadow Demon and Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
Wraith King
* Heroes with high burst damage and Black King Bar can take down Dark Willow quickly: Phantom Assassin, Sven, Wraith King
Wraith King
* Wraithfire Blast is quite predictable, and players with good reflexes will disjoint it with 
Blade Fury.
* 
Omnislash with Diffusal Blade & Aghanim's Scepter can prevent Wraith King from reincarnating unless he has his Aghanim's Shard that removes the mana cost from Reincarnation.
Primal Beast
* Primal Beast can use Uproar to tank a portion of Omnislash, making him much more likely to survive it. Primal Beast can also charge away from Omnislash using Onslaught as the spell ends.
* Blade Fury will never do more damage than Uproar once the stacks are activated.
* Primal Beast is very commonly buying items that are good against Juggernaut, such as Ethereal Blade and 
Heart of Tarrasque.
* Primal Beast has one of the few ultimates that can prevent Juggernaut from spinning away with a teleport.
Wraith King
* Wraith King, Medusa, Storm Spirit and other mana dependent heroes will have diminished impact on a fight if they survive Fiend's Grip due to its mana steal.
Wraith King
* Heroes with illusions and summons can swarm and overwhelm Bane, who has no area abilities to deal with them outside from Aghanim's Shard upgraded 
Brain Sap: Broodmother, Chaos Knight, Naga Siren, Nature's Prophet, Phantom Lancer, Terrorblade, Visage, Warlock, Wraith King.
Primal Beast
* 
Malefice will prevent Primal Beast from doing anything for a long duration even in the early game when at his strongest.
* 
Midnight Pulse will scale with his max health so will do a ton of damage combined with any generic stun or Enigma's own abilities.
* Primal Beast relies completely on mobility to do damage, 
Black Hole makes sure he cannot use any abilities or threaten heroes he is typically good against.
Wraith King
* Like Abbadon's Borrowed Time, Reincarnation can bring Wraith King back to life, giving him a second chance to counter initiate or escape after a Black Hole combo. And since Enigma is not used to buy Diffusal Blade, this can be a very big problem for him.
* Without protection from Black King Bar, Wraith King can also cancel Black Hole with Wraithfire Blast that can also deal damage over time, putting Blink Dagger on cooldown.
* Vampiric Spirit can summon many skeleton warriors that can be used to deal with Enigma's Eidolons.
Primal Beast
* Primal Beast's abilities require movement to deal damage, making 
Rupture potentially deadly and debilitating. Furthermore, its initial damage based on the target's current health is devastating to a full-health Primal Beast with his high strength gain and thus high HP.
* Due to his reliance on spells, Primal Beast is vulnerable to 
Blood Rite's powerful silence without items to counter it.
Wraith King
* Reincarnation makes Wraith King nearly impossible to gank with Rupture.
* Vampiric Spirit restores Wraith King's health, reducing the effect of Thirst.
Additional:
* Rupture is meaningless while Reincarnation is off cooldown.
* Vampiric Spirit and Mortal Strike prevent Bloodseeker from achieving 
Thirst bonuses.
Wraith King
* Broodmother can easily clear Wraith King's skeletons with 
Spawn Spiderlings and summon spiderlings in their place.
* With Diffusal Blade, Broodmother can prevent Wraith King from reincarnating unless Wraith King has his Aghanim's Shard.
Primal Beast
* While Broodmother can hide in the trees with 
Spin Web, Primal Beast's ability to trample trees down can give him an edge in catching her.
* 
Insatiable Hunger will not do much vs Primal Beast's onslaught of disables.
* While 
Silken Bola can slow Primal Beast down, it's not enough to stop Trample from doing more damage than Broodmother can do back.
* Spawn Spiderlings will be destroyed by Onslaught and Trample very easily.
Wraith King
*
Wraithfire Blast is easy to disjoint with Shukuchi or Time Lapse, and it's the only way to break Weaver's Linken Sphere.
Diffusal Blade, Weaver can prevent 
Reincarnation from triggering until Wraith King gets his shard.
Shukuchi.
Geminate Attack.
Diffusal Blade, until Wraith King purchases Aghanim's Shard to remove 
Reincarnation's manacost.
* Wraith King has no other disables and no mobility, allowing Weaver to chase or escape Wraith King as he wishes.
* With the Mana Break talent and
Additional:
* Weaver can run away after killing Wraith King once thanks to
* Wraithfire Blast is quite predictable. If Weaver is quick, he will disjoint it with Shukuchi and proceed to chase Wraith King down.
* Shukuchi does have a fade time. They cannot disjoint it if you use it right next to them. They will be stunned and take damage; however they will still become invisible if they used Shukuchi before the stun hits.
* Weaver can easily harass Wraith King out of his lane thanks to his high base damage and
* Weaver can burn Wraith King's mana quickly with his {ValueColor:1|Mana Break|15tal} {Symbol:Talent} talent or
Primal Beast
*
Shukuchi allows Weaver to have faster movement speed and can outrun Primal Beast in most instances, such as while he is trampling.
The Swarm can make him vulnerable to ranged attacks. Primal Beast also has an innately slow attack speed and will take a long time destroying the bugs.
Time Lapse allows Weaver to negate and heal burst damage, which Primal Beast is reliant on.
* Trample disarms Primal Beast, so casting
