Lycan
* Heroes that heavily depend on illusions or summons, (
Naga Siren, 
Terrorblade, 
Phantom Lancer, 
Lycan,...) are vulnerable to Sleight of Fist and even more so if Ember Spirit has 
Battle Fury.
Void Spirit
* Ember Spirit has much higher mobility in 
Fire Remnant than Void Spirit.
* Ember's 
Flame Guard is effective against Void Spirit's spells, as most of them deal magical damage.
* The root from 
Searing Chains prevents Void Spirit from using Dissimilate or Astral Step.
Lycan
* 
Great Cleave will kill Lycan's summons very rapidly.
* 
Warcry will allow Sven and his allies to tank Lycan's damage, which is mainly physical.
* 
Storm Hammer will damage and stun Lycan's as well as his summons.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: 
Sven, 
Tiny, 
Wraith King, 
Ogre Magi.
Lycan
* Melee heroes who rely on summons, illusions, or clones will trigger Counter Helix more often, thus taking more damage: 
Meepo, Lycan, Phantom Lancer
Additional:
* 
Berserker's Call can keep Lycan in place during his Shapeshift even through 
Black King Bar.
* 
Counter Helix is very effective against Lycan because of his summons.
* 
Culling Blade will prevent Lycan from running away with Shapeshift when he drops low.
Void Spirit
* Heroes with burst damage of their own won't be afraid to go toe to toe with Void Spirit, like 
Ursa, 
Lifestealer, or 
Axe.
Lycan
* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: Lycan, 
Arc Warden, 
Warlock, 
Chen
Void Spirit
* Special mention to 
Legion Commander, as she can lock down Void Spirit for a long amount of time without worrying too much about being killed by him during the 
Duel.
Lycan
* 
Dragon Knight's insanely high armor and splash damage can cause Lycan to struggle taking him down.
Void Spirit
* Heroes who can match Void Spirit's mobility (like the aforementioned 
Ember Spirit or 
Queen of Pain) or tank his spells (Dragon Knight or 
Centaur Warrunner) are very problematic for him.
Lycan
* 
Guardian Angel completely negates all of Lycan's damage since Lycan mainly deals physical damage.
* 
Purification can also be a problem for Lycan, as Purification deals damage around the target, which poses a problem for him and his summons.
Lycan
* 
Arctic Burn allows Winter Wyvern to escape Lycan, even when he uses his ultimate.
* 
Splinter Blast is very effective in dealing with Lycan's summons.
* 
Cold Embrace saves allies from Lycan's raw physical damage and can buy allies enough time to turn the tide of battle.
* 
Winter's Curse stops Lycan in his tracks and is very effective because of his summons.
Additional:
* All of Lycan's damage is physical which is totally negated by Cold Embrace.
* Lycan often moves around with large amount of creeps, wolves created by 
Summon Wolves and neutral creep dominated by 
Helm of the Dominator which can be easily cleared by Splinter Blast or used as a great source of damage by Winter's Curse. If you catch Lycan with creeps nearby and affected by 
Shapeshift using Winter's Curse on him will most certainly end up with his death.
Void Spirit
* One hit with 
Jinada should be sufficient in removing Void Spirit's shield most of the time.
* 
Track negates much of Void Spirit's escape abilities by revealing his position and prevents him from rotating effectively.
Lycan
* Can cast 
Demonic Conversion on one of Lycan's Wolves, making this a numbers fight.
* 
Malefice will greatly reduce his ability to engage
* 
Midnight Pulse can steep an area making it harder for Lycan to engage in.
Lycan
* A well landed 
Fissure can potentially take Lycan out of the fight for several seconds, who heavily relies on precious seconds from Black king bar and Shapeshift to fight.
* 
Aftershock reduces the effectiveness of his summons and can prove quite irritating for Lycan.
* 
Echo Slam is very powerful with the sheer amount of Lycan's units and will cause him to think twice when pushing towers.
Lycan
* Tidebringer's cleave will cripple any of his summons.
* Could potentially build Heaven's Halberd to cripple Lycan even more.
Additional:
* 
Tidebringer can be used to kill Lycan's summons.
* Can also build into 
Heaven's Halberd which will disable Lycan's auto attacks, crippling him even more.
Void Spirit
* 
Spirit Siphon and 
Exorcism can damage through his 
Resonant Pulse shields.
* 
Silence can prevent Void Spirit escape or contributing much in fights.
Lycan
* Brewmaster can waste a large portion of Lycan's ultimate by putting him in Cyclone.
* Lycan has no way to stop Brewmaster from using Primal Split by himself.
* Lycan's team often tries to push towers as a group, and Brewmaster excels at winning teamfights while trying to defend a tower.
Lycan
* Paralyzing cask bounces between him and his wolves, keeping him stunned for long amounts of time.
Lycan
* 
Kraken Shell grants him massive physical attack protection
* 
Anchor Smash will wipe the area, clearing Lycan's wolves.
Void Spirit
* Queen of Pain can 
Blink to both escape and initiate onto Void Spirit.
* She is also a very common 
Orchid Malevolence carrier, which can prevent Void Spirit from contributing much in fights.
Void Spirit
* Wins on the central line, thanks to its strong nukes 
Shadowraze, because of which Void Spirit cannot approach the creeps to farm gold and overtake Shadow Fiend by level
Additional:
* Wins on the central line, thanks to its strong nukes Shadowraze, because of which Void Spirit cannot approach the creeps to farm gold and overtake Shadow Fiend by level
Lycan
* All of Timbersaw's spells deal AoE damage, killing Lycan's summons very quickly.
* 
Reactive Armor will gain stacks quickly because of Lycan's summons.
Void Spirit
* The brutal physical damage of 
Slithereen Crush and 
Bash of the Deep can quickly remove Void Spirit's shield and stun him for a while.
* 
Corrosive Haze provides vision of Void Spirit while he is running away and 
Guardian Sprint allows Slardar to quickly close the gap
Void Spirit
* 
Lion's instant cast point shuts down his initiation and buys time for his allies to catch up.
* 
Void Spirit has to be cautious when fighting, as he has no protection against 
Finger of Death. If caught out in a stun, the high magic damage could end him quickly.
Lycan
* Lycan's wolves deal little damage to Bristleback, and are easily killed by Quill Spray, even when they're invisible.
* Lycan's lack of burst damage makes it very hard for him to kill Bristleback, especially when his back is turned.
Additional:
* 
Quill Spray can be used to kill Lycan's summons.
* 
Bristleback allows him to stay alive against Lycan while dishing out counter attacks
* He can overpower Lycan with his 
Warpath instead.
Lycan
* Lycan is a hero focused entirely on single target physical damage and lacks disables or AoE damage. Due to this, he will have difficulties dealing with illusions or Naga Siren's Ensnare.
Void Spirit
* 
Doom is effective against every hero, and Void Spirit is no exception. Being unable to cast spells or items during fights for 16 seconds nullifies his impact entirely.
* Doom has a very versatile build and can consume creeps which has abilities that can stun or provide additional magic resistance.
* Doom's high strength gain and versatility in items can be effective against Void Spirit's magical damage.
Lycan
* 
Primal Roar allows Beastmaster to keep Lycan in place after he used his Shapeshift.
Void Spirit
* Heroes that can purge his slow and disables are very difficult to go on and their team: 
Abaddon, 
Oracle.
Void Spirit
* Heroes that can purge his slow and disables are very difficult to go on and their team: Abaddon, Oracle.
Lycan
* 
Treant Protector grants protection against his attacks with 
Living Armor and his ultimate, 
Overgrowth is a massive AoE disarm and root that pierces spell immunity, causing trouble to Lycan. You will find yourself in need of an ally's dispel or forced to pop Black King Bar for its dispel.
Additional:
* Lycan has no kind of teleport, being only able to walk, and heavily relies on his attacks. As Overgrowth roots and disarms the targets, Lycan can't do much in an overgrowth field.
Void Spirit
* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: 
Puck, Void Spirit, 
Mars.
Void Spirit
* Heroes who can match Void Spirit's mobility (like the aforementioned Ember Spirit or Queen of Pain) or tank his spells (Dragon Knight or Centaur Warrunner) are very problematic for him.
Lycan
* 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.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.
Lycan
* Heroes who summon multiple units that are not spell immune. Nature's Prophet,Lycan,
Beastmaster
Lycan
* 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.
Lycan
* Heroes with summoned units don't fare well against Dawnbreaker. (Phantom Lancer ,Beastmaster ,Lycan).
Lycan
* Lycan cannot escape from a Pounce even if he uses Shapeshift, and has no disabling abilities to stop Slark.
Lycan
* 
Pugna's 
Decrepify prevents the target from taking physical damage or doing damage, which poses a huge problem for Lycan, as he mainly deals physical damage.
Lycan
* 
Faceless Void can lock Lycan down with his 
Chronosphere pinning him down as long as his ultimate is up.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.
Lycan
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, 
Storm Spirit, Ember Spirit, Lycan, 
Bloodseeker, 
Anti-Mage, 
Timbersaw.
Void Spirit
* Void Spirit can easily be bursted down by Puck's high magic damage spells in early game.
* Wanning Rift and Dream Coil prevent him from using two of his important mobility abilities: 
Dissimilate and 
Astral Step.
Additional:
* 
Dream Coil prevents the usage of Void Spirit's escape abilities and limits his damage output in fights almost entirely.
* Killing Puck in the late game becomes difficult when they obtain a 
Eul's Scepter of Divinity, 
Blink Dagger, and 
Phase Shift.
Lycan
* A Lycan with Shapeshift can always run down Puck for a very quick kill due to its low armor. It is important to abuse as many cliffs and trees as possible to escape from a Lycan.
Lycan
* Heroes who rely heavily on melee attacks and lack early spell immunity are easily blocked and interrupted by Ink Swell: Lycan, Ursa, 
Troll Warlord.
Additional:
* 
Stroke of Fate deals more damage when it hits more targets which makes it very effective in dealing with Lycan and his units.
* 
Soulbind prevents Lycan from running away and makes him very easy to deal with.
Lycan
* Her 
Mana Shield is too tough for Lycan to break.
* 
Mystic Snake can hit for a massive damage once it spread between his summons.
Additional:
* Can be easily petrified despite his speed.
* Summoned wolves will be targeted by Split Shot or Mystic Snake
Void Spirit
* Heroes who take a long time to become strong are in for a rough mid game, such as 
Outworld Destroyer, 
Magnus, 
Medusa, and Anti-Mage.
Void Spirit
* 
Fiend's Grip and 
Nightmare are very useful to lock down Void Spirit.
* 
Brain Sap can be difficult for Void Spirit to deal with in the laning stage.
Lycan
* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, 
Bane, 
Phantom Assassin.
Void Spirit
* Meepo's 
Earthbind can easily lockdown Void Spirit.
* Meepo and his clones can easily burst Void Spirit's Resonant Pulse.
Void Spirit
* Void Spirit can dodge Earthbind with Dissimilate and Astral Step, giving him a good chance to escape. If he gets caught anyways, Resonant Pulse allows him to retaliate.
Void Spirit
* 
Poison Attack makes it hard for Void Spirit to lane against him.
* 
Corrosive Skin reduces the magical damage from Void Spirit's spells.
Lycan
* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: 
Clinkz, Pugna, Nature's Prophet, 
Dark Seer, Lycan, 
Tusk
Lycan
* Phantom Assassin's 
Blur is a real problem for Lycan, as he relies entirely on direct attacks to deal damage.
Lycan
* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.
Lycan
* 
Charge of Darkness allows Spirit Breaker to catch up to Lycan after he uses Shapeshift.
Additional:
* Vision from Charge of Darkness will easier to catch Lycan Shapeshift and Charge of Darkness out of reach Lycan Summon Wolves and Lycan's other creeps. Until upgrade 
Aghanim's Scepter faster catching Lycan Shapeshift.
Lycan
* 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.
Void Spirit
* 
Refraction negates all of Void Spirit's burst damage.
* 
Meld quickly burns through Resonant Pulse.
Lycan
* Multiple attackers thanks to summoned units or clones: Meepo, 
Witch Doctor, Lycan, 
Enigma, Shadow Shaman
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, Chaos Knight, Naga Siren (bonus for her 
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: 
Slark, 
Gyrocopter, Queen of Pain, Shadow Shaman (
Shackles), 
Jakiro, Pugna, 
Doom
Lycan
* Lycan relies heavily on right clicks making Untouchable very effective against him.
* If he tries to run away Impetus will do huge amounts of damage.
Additional:
* She can 
Enchant one of the wolves to her side.
* Lycan will struggle greatly to harm Enchantress through her 
Untouchable which can seriously slow down Lycan's attack speed even if Lycan is spell immune.
Lycan
* Heroes with haste can negate Enchant's slow: 
Weaver, Dark Seer, Lycan, Centaur Warrunner.
Lycan
* Shapeshift increases Lycan's movement speed and renders him unslowable, allowing him to easily avoid and escape Ancient Apparition's abilities.
* Lycan has fast summons, both his wolves from Summon Wolves can do heavy damage to Ancient Apparition due to his immobility and low armor.
Void Spirit
* Dissimilate and Astral Step allow Void Spirit to quickly escape from Cold Feet.
* Void Spirit deals both magical and physical damage, which makes Ancient Apparition an easy target to ambush.
* If Void Spirit purchases Aghanim's Scepter, the silence provided by Resonant Pulse can disrupt Ancient Apparition during fights, as he is entirely reliant upon spells to contribute.
Lycan
* Lycan can clear waves of Chen's creeps with his wolves from Summon Wolves, especially once Lycan takes +2 Wolves summoned talent. And even though Chen can convert one of his wolves with 
Holy Persuasion, Lycan can counter this by buying 
Helm of the Overlord to regain control of it. Uncontrollable wolves summoned from 
Aghanim's Shard upgrade Summon Wolves cannot be converted with Holy Persuasion.
* Shapeshift allows him to chase down Chen and kill him easily.
* 
Howl can reduce attack damage of both, Chen and his creeps.
Void Spirit
* Heroes that can easily bypass Chen's creeps to get to Chen: 
Riki, Tusk, Clinkz, 
Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, 
Earth Spirit, 
Spirit Breaker.
Lycan
* The movement speed granted from Shapeshift means that Spectre has no way to punish Lycan if he wants to splitpush or pick off supports. Furthermore, he will kite 
Haunt and cannot be slowed by 
Spectral Dagger.
* Lycan is often part of an early game push strategy which is often the best counter to Spectre because she needs a lot of time and space to come online as a late game carry.
Void Spirit
* Void Spirit is strong against heroes who cannot deal with his rotations due to his mobility. Such heroes include 
Spectre, Gyrocopter, 
Morphling, and Chen.
Lycan
* Windranger tends to fare badly against high mobility heroes that can easily dodge Powershot, close the gap on her when she uses Windrun or escape from Focus Fire's reach. Examples of such heroes include Spirit Breaker, Lycan, Storm Spirit, Earth Spirit, Void Spirit, Slark and others.
Void Spirit
* Void Spirit deals entirely magical damage in the early game, ignoring her evasion from 
Windrun.
* A Void Spirit with fast reaction time can use Dissimilate or Astral Step to dodge 
Powershot.
Additional:
* Void Spirit deals entirely magical damage in the early game, ignoring her evasion from Windrun.
* A Void Spirit with fast reaction time can use Dissimilate or Astral Step to dodge Powershot.
Lycan
* Howl reduces a good chunk of Marci's attack damage that she relies heavily on, and the armor reduction works better on her because of her low armor.
* Shapeshift renders Lycan immune to slow from Rebound and Unleash.
Void Spirit
* Heroes that can reliably kite out Dispose, Unleash and dodge Rebound, like Ember Spirit, Void Spirit, Storm Spirit, Anti-Mage, Faceless Void, Puck or always build items like Blink Dagger and 
Force Staff.
Lycan
* Heroes who can summon illusions and summons because Terrorblade has no abilities to deal with multiple enemies at once outside Reflection: Shadow Shaman, Naga Siren, Broodmother, Lycan, Enigma, Chaos Knight, Phantom Lancer, 
Shadow Demon, Dark Seer, Nature's Prophet, 
Invoker, Morphling, Visage, 
Grimstroke with Aghanim's Scepter.
Void Spirit
* Heroes with abilities that can lock down Terrorblade and prevent him from using Sunder: Bane, 
Batrider, 
Earthshaker, 
Elder Titan, Faceless Void, Invoker, Legion Commander, Mars, 
Primal Beast, Riki, Shadow Shaman, 
Silencer, 
Vengeful Spirit, Void Spirit.
Additional:
* Void Spirit's high mobility becomes a nuisance to Terrorblade.
* Void Spirit's arsenal of magic damage is effective against Terrorblade's low strength.
* Terrorblade has no disables to prevent Void Spirit from escaping.
Lycan
* 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.
Void Spirit
* Heroes with either magical, physical or pure damage burst: Bane, Ember Spirit, 
Leshrac, 
Lina, 
Luna, 
Nyx Assassin, Phantom Assassin, 
Skywrath Mage, 
Tinker, Ursa, Void Spirit.
Void Spirit
* Void Spirit can greatly pressure Morphling's farm, which is very bad for a hero who needs a large amount of space.
* 
Waveform does not provide better mobility than Astral Step.
* If Morphling shifted all of his strength to agility, he can be bursted down by Void Spirit before he can react.
* Doing an Ethereal Blade combo on Void Spirit is incredibly difficult, as Dissimilate and Astral Step can allow him to escape or dodge the projectile.
Void Spirit
* Astral Step and Dissimilate makes a quick work of Phantom Lancer's illusions.
* Resonant Pulse helps clear illusions and protects Void Spirit from Phantom Lancer's physical damage and with the Aghanim's Scepter upgrade, it prevents Phantom Lancer from casting his abilities.
* Void's Spirit mobility makes it hard for him to chase down with Phantom Rush.
Lycan
* He can send wolves to defuse 
Proximity Mines, and he can catch up Techies and kill him before they can deny themselves. Even if the suicide is successful, Lycan can still survive because of his tankiness.
Void Spirit
* Keeping Void Spirit inside 
Wukong's Command is a very tricky task, especially in the early and mid game. In addition, if Monkey King is in a bad position, a well placed Aether Remnant can easily pull him out of the ring.
* Getting stacks of 
Jingu Mastery can be difficult when attacking Void Spirit.
Lycan
* Mirana's Leap is ineffective if Lycan uses Shapeshift. It also allows him to dodge Sacred Arrow.
Void Spirit
* A good choice against Invoker, as it has some advantage with the help of abilities.
* With the Dissimilate, Voidspirit can evade Invoker's skills, going to another world where he does not receive damage. The same ability to run away or attack quickly.
* Astral Step moves quickly from point to point, which also reduces the Invoker's probability that he will hit him with skills and cause at least some damage.
Additional:
* A good choice against Invoker, as it has some advantage with the help of abilities.
* With the Dissimilate, Voidspirit can evade Invoker's skills, like 
Chaos Meteor or 
E.M.P., going to another world where he does not receive damage. The same ability to run away or attack quickly.
* Astral Step moves quickly from point to point, which also reduces the Invoker's probability that he will hit him with skills and cause at least some damage.
Void Spirit
* Void Spirit can easily dodge Gyrocopter's {Ability ID:Homing Missile|gyrocopter} with the help of Dissimilate.
* Void Spirit can partly dodge 
Call Down via Dissimilate or move out of its range with Astral Step.
* Gyrocopter has no escape abilities, which benefits Void Spirit's high mobility.
Lycan
* Shapeshift allows Lycan to get close and disable Marksmanship.
* Shapeshift also makes him immune to slows like Drow Ranger's Frost Arrows.
Additional:
* The Wolves's speed causes the knockback from 
Gust to be ineffective.
* Drow Ranger lacks escapes and loses her 
Marksmanship when someone is near her. Lycan can take advantage of these weaknesses of Drow Ranger.
Lycan
* Shapeshift is useful for killing or escaping Silencer.
* Summon Wolves, can be used to hunt and harass silencer - even when Lycan himself can't fight.
Lycan
* Lycan's high health allows him to easily shrug off Nyx Assassin's burst damage and fend him off.
* As Lycan commonly buys Black King Bar, he can use it to freely attack Nyx Assassin and chase after him with Shapeshift.
* Lycan can also use his wolves from Summon Wolves to attack Nyx Assassin while he has 
Spiked Carapace active without getting stunned himself.
Lycan
* Shapeshift allows Lycan to chase down Earth Spirit.
Lycan
* Shapeshift allows Lycan to escape from Upheaval with maximum movement speed.
* Warlock doesn't have a good solution to deal with Lycan's wolves from Summon Wolves.
Lycan
* Lycan doesn't care much about Lich's slows thanks to Shapeshift.
* Chain Frost can bounce to the wolves that Lycan summons.
Additional:
* 
Lich possesses a lot of slows, which Lycan doesn't care about when he Shapeshifts.
* Lich has no in-built escape, which makes him a good target for Lycan.
Lycan
* Void's slow is useless against Lycan by activating Shapeshift.
* Night Stalker's single target abilities (with the exception of Void upgraded by Aghanim's Scepter) is not very effective against Lycan's Summon Wolves during the early and mid game.
Lycan
* 
Magnetic Field is useless against melee heroes, so Lycan can attack Arc Warden without missing.
* 
Flux doesn't affect Lycan that much, because Shapeshift grants immunity to slows and because he is never alone.
* If their 
Tempest Double has been called, Lycan can still kill Arc Warden before the double expires.
Lycan
* Heroes who rely on physical damage output to be effective will fare badly against Muerta's 
Pierce the Veil: Phantom Assassin, Terrorblade, 
Drow Ranger, Lifestealer, Anti-Mage, 
Alchemist, Lycan, Clinkz, Sniper.
Lycan
* Heroes with abilities that can close the gap can easily kill Muerta: Storm Spirit, Earth Spirit, Ember Spirit, Void Spirit, Lycan, Chaos Knight, Tusk.
Void Spirit
* Heroes with abilities that can close the gap can easily kill Muerta: Storm Spirit, Earth Spirit, Ember Spirit, Void Spirit, Lycan, Chaos Knight, Tusk.
Void Spirit
* Heroes who take a long time to become strong are in for a rough mid game, such as Outworld Destroyer, Magnus, Medusa, and Anti-Mage.
Lycan
* You can easily kill a squishy Sniper, due to your high movement speed and his lack of escape.
Lycan
* Once you get a Black King Bar, squishy spellcasters like 
Zeus, Skywrath Mage and others will be probably easy to deal with.
Lycan
* Heroes with low armor and little mobility, like 
Huskar, 
Io, etc. will also have an unfortunate fate.
Void Spirit
* Heroes who take a long time to become strong are in for a rough mid game, such as Outworld Destroyer, Magnus, Medusa, and Anti-Mage.
Lycan
* Once you get a Black King Bar, squishy spellcasters like Zeus, Skywrath Mage and others will be probably easy to deal with.
Lycan
* Lycan and Weaver has abilities that allow them to move at maximum movement speed, and those abilities can't be dispelled, potentially wasting the slow from Demonic Purge.
Void Spirit
* Heroes who take a long time to become strong are in for a rough mid game, such as Outworld Destroyer, Magnus, Medusa, and Anti-Mage.
Void Spirit
* With Aghanim's Scepter, Broodmother will gain access to 
Spinner's Snare, which will allow her to create invisible lines on her webs from 
Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: Phantom Assassin, Nyx Assassin, 
Mirana, 
Bounty Hunter, 
Templar Assassin, Riki, Spirit Breaker, Anti-Mage, Tusk, Ursa, Nature's Prophet, Enigma, Void Spirit, Magnus etc.
Void Spirit
* Void Spirit's AoE damage can make short work of Broodmother's spiderlings
* Even if she is within the range of her spiderwebs from Spin Web Broodmother cannot escape Void Spirit's mobility.
* However, Spinner's Snare from Aghanim's Scepter can be very hazardous for Void Spirit, as it allows Broodmother to create invisible lines on her webs from Spin Web that will root Void Spirit, deal damage over time to him and reveal him if he unwittingly steps on them, disrupting Void Spirit's ganking or escaping attempts with Dissimilate and Astral Step while also alerting Broodmother on his attempts to ambush her and her allies.
Additional:
* Void Spirit's AoE damage can make short work of Broodmother's spiderlings

Void Spirit
* Heroes with burst damage of their own won't be afraid to go toe to toe with Void Spirit, like Ursa, Lifestealer, or Axe.
Lycan
* Lycan's ultimate makes him immune to slows from Ursa's 
Earthshock as well as allowing him to outmaneuver Ursa during 
Enrage. Lycan can also easily chase down Ursa while shapeshifted, should Ursa try to flee.
Lycan
* Heroes who have summons, which can be quickly cleared by his powerful area of effect skill: Nature's Prophet, Enigma, Lycan
Void Spirit
* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.
Lycan
* 
Keeper of the Light has a blind, which causes Lycan to miss his attacks.
Lycan
* Heroes with hastes: Dark Seer, Lycan
Void Spirit

Lycan
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.
Lycan
* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.
Lycan
* Rupture completely negates Lycan's high mobility.
Rupture completely negates Lycan's high mobility.
Bloodrage.
* All of Lycan's summons are good sources of healing with Bloodrage.
Additional:
*
* All of Lycan's summons are good sources of healing with
Void Spirit
*
Rupture will fully damage Void Spirit during his ultimate, removing his main escape mechanic during fights and his way to disrupt them heavily. 
Blood Rite will force Void Spirit to use Dissimilate or Astral Step or be silenced. In the latter's case, it can be dangerous when combined with Rupture.
*
