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.
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.
Lycan
* Rupture completely negates Lycan's high mobility.
* All of Lycan's summons are good sources of healing with Bloodrage.
Additional:
* 
Rupture completely negates Lycan's high mobility.
* All of Lycan's summons are good sources of healing with 
Bloodrage.
Tidehunter
* Kraken Shell's dispel does not restore mana lost through 
Astral Imprisonment, and the stolen mana can really hurt Tidehunter's ability to initiate
* 
Arcane Orb high pure damage ignores Tidehunter's Armor, and is barely affected by his Kraken Shell's damage block
* It is also completely unaffected by Anchor Smash, due to it relying on Outworlds Mana pool
* 
Sanity's Eclipse is effective on Tidehunter's poor mana pool, While it is reduced by Kraken Shell, the damage reduction is negligible.
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.
Tidehunter
* Kraken Shell neither dispels nor provides damage reduction against 
Spirit Siphon. This ability also drains health based on percentage damage, making Tidehunter's large healthpool a very appealing target. Furthermore, the health gained from the Siphon is independent from the amount of damage dealt, so Death Prophet will always heal a large amount of from Tidehunter's pool even if Tidehunter has magic reduction items or abilities on him, which makes her an untargetable enemy for you as this easily outweights any damage output you can provide.
* 
Exorcism is yet another ability from which Kraken Shell provides no useful protection, as the spirits completely ignore the damage block and are unaffected by the dispel. This ability also creates an unfriendly area where your blink will be constantly cancelled, reducing your ability to land a good Ravage.
* Ravage does not stop neither Spirit Siphon nor Exorcism, making the ability mostly ineffective against her. Additionally, Death Prophet usually builds 
Eul's Scepter of Divinity, which can be used to dodge the stun entirely.
Tidehunter
* Kraken Shell provides no protection against 
Omnislash or 
Swiftslash.
* If timed correctly, Omnislash, Swiftslash and 
Blade Fury are all capable of dodging Ravage, giving Juggernaut several tools to render your strongest ability moot.
* Blade Fury is an effective way to harass Tidehunter in the laning stage as Tidehunter has no means of getting Juggernaut away from him. 
Healing Ward also greatly minimizes Tidehunter's ability to harass Juggernaut.
* 
Blade Dance minimizes the effectiveness of Anchor Smash's damage reduction.
Tidehunter
* In the mid-game, Tidehunter relies on 
Kraken Shell to stay alive and get his 
Ravage off. Apart from Thunder Strike, none of Disruptor's abilities can be dispelled, so it's rather easy to trap him inside Kinetic Field and Static Storm.
* Be mindful, however, that Kraken Shell still makes Tidehunter very tanky, so be sure that you can kill him with your combo or your partners while he is silenced and trapped.
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
* 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.
Tidehunter
* No matter how Tidehunter builds tanky items such as (
Guardian Greaves, 
Crimson Guard or 
Pipe of Insight), all it needs is for him to fall below a certain percentage of health for him to fall to Reaper's Scythe.
Tidehunter
* Both 
Gush and Ravage do little damage against Counterspell.
* Blink helps Anti-Mage escape through 
Anchor Smash.
* Tidehunter's small mana pool can be eated by Mana Break, preventing to spam his abilities and ignores the protection from Kraken Shell.
Additional:
* 
Mana Break quickly burns Tidehunter's mana pool, preventing him from spamming his abilities, and Kraken Shell does not mitigate the bonus damage component.
* 
Blink allows Anti-Mage to enter combat quickly and safely after Ravage.
* A well-timed 
Counterspell can reflect Gush back at Tidehunter.
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.
Tidehunter
* Infernal Blade deals scaling damage and is useful against high HP targets such as Tidehunter.
* 
Doom prevents Tidehunter from casting his Gush, Anchor Smash and Ravage, making him useless in team fights.
* If Doom chooses the Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, he can also disable Kraken Shell, reducing his survivability.
Lycan
* 
Primal Roar allows Beastmaster to keep Lycan in place after he used his Shapeshift.
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.
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.
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.
Lycan
* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: Lycan, 
Arc Warden, 
Warlock, 
Chen
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.
Lycan
* Heroes that can summon units will have their summons destroyed very quickly if badly micro-managed, like Chen, Lycan, and Phantom Lancer.
Lycan
* Heroes who summon multiple units that are not spell immune. Nature's Prophet,Lycan,
Beastmaster
Tidehunter
* Heroes who relies on high armor such as 
Dragon Knight, 
Tidehunter, and 
Pudge can be melted by Eye of the Storm.
Additional:
* Kraken Shell's dispel does not restore damage stolen by 
Static Link, and the stolen damage easily offsets Anchor Smash's damage reduction. Razor can keep attacking Tidehunter from afar, denying his chance to use Anchor Smash.
* 
Eye of the Storm melts Tidehunter's armor and makes him much less tanky.
* Razor can chase Tidehunter by himself without relying on actual crowd control ability, so the strong dispel from Kraken Shell is less useful.
Lycan
* Heroes with summoned units don't fare well against Dawnbreaker. (Phantom Lancer ,Beastmaster ,Lycan).
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.
Tidehunter
* Heroes with strong team-fight abilities (especially ultimates) like Tidehunter, 
Brewmaster, 
Death Prophet, etc.
Additional:
* 
Fade Bolt reduces damage output of Anchor Smash.
* Ravage is an easy target to 
Spell Steal, so always be sure to use Anchor Smash immediately after Ravage when playing against a Rubick.
* Spells stolen by Rubick are potentially stronger due to the lack of cast animations, his talents, and his passive, 
Arcane Supremacy.
Lycan
* Dragon Knight's insanely high armor and splash damage can cause Lycan to struggle taking him down.
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
* Heroes who have summons, which can be quickly cleared by his powerful area of effect skill: Nature's Prophet, 
Enigma, Lycan
Tidehunter
* Heroes with large physical resistance do not counter Muerta's 
Pierce the Veil such as 
Omniknight or Tidehunter.
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.
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
Tidehunter
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter, 
Bristleback, 
Slardar.
Tidehunter
* 
Viper STrike cancels out Kraken Shell and stops the hard dispel from passively activating, preventing Tidehunter from functioning as a frontline tank.
* Anchor Smash is mostly irrelevant against a ranged hero like Viper.
* Tidehunter relies on the threat of Ravage, which has an obscenely long cooldown. Viper can exploit the downtime with his short cooldowns.
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
Tidehunter
* Luna often builds Black King Bar, and none of Tidehunter's spells can bypass spell immunity.
* Though Anchor Smash can weaken Luna's physical damage, it does not weaken her magical damage, which means that 
Lucent Beam and 
Eclipse deal a lot of magic damage in the early and mid-game, which can bypass Tidehunter's Kraken Shell.
Additional:
* Luna often builds Black King Bar, and none of Tidehunter's spells can bypass spell immunity.
* Though Anchor Smash can weaken Luna's physical damage, it does not weaken her magical damage, which means that Lucent Beam and Eclipse deal a lot of magic damage in the early and mid-game, which can bypass Tidehunter's Kraken Shell.
Tidehunter
* Heroes that rely on base damage: 
Luna, Phantom Lancer are easily countered with Anchor Smash.
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.
Tidehunter
* Kraken Shell easily dispels the lengthy stun from 
Shackleshot.
* Kraken Shell (and possibly Anchor Smash) blocks huge amount of damage from 
Focus Fire.
* Anchor Smash is one of the few sources of True Strike, which means Tidehunter can deal significant damage through 
Windrun, while also reducing Windranger's damage output.
Additional:
* Kraken Shell can easily dispel Shackleshot after he has taken a certain threshold of damage.
* Ravage provides excellent lockdown against Windranger, allowing his teammates to kite her throughout the game.
* When Tidehunter has 
Aghanim's Shard, he will gain access to 
Dead in the Water, allowing him to lock down Windranger at any time. When Windranger tries to move away from the anchor with Windrun, she will be effectively slowed, preventing her from escaping.
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.
Tidehunter
* Kraken Shell dispels Fiend's Grip, wasting it easily. Additionally, in late game, it secures premature dispell of a level 4 Nightmare, in case of continuous Bane's rightclicks.
* Enfeeble only reduces distance of Gush, but not of Anchor Smash or Ravage, and thanks again to Kraken Shell, is easily dispellable for him in team fights.
* Ravage affects large area, effectively reaching Bane's spot for applying Fiend's Grip, even with Glimmer Cape, Aether Lens and/or Aghanim's Scepter.
Additional:
* Kraken Shell dispels 
Fiend's Grip, wasting it easily.
Lycan
* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, 
Bane, Phantom Assassin.
Tidehunter
* Kraken Shell can dispel Flaming Lasso.
* If Batrider drags Tidehunter back towards his team, it can be setup for a well placed Ravage.
Additional:
* Kraken Shell is very useful against 
Sticky Napalm and 
Flamebreak, easily dispelling them regularly.
* Tidehunter is probably the worst hero to target with 
Flaming Lasso, as Kraken Shell will remove it and Tidehunter often survives long enough to cast Ravage in the middle of Batrider's team. At the same time, if Batrider initiates on his teammate, Tidehunter will have the perfect opportunity to counter-initiate.
Tidehunter
* Kraken Shell and Anchor Smash makes it very difficult for Phantom Lancer's illusions to deal damage to Tidehunter.
* Ravage will stun the real Phantom Lancer while clearing most of his illusions.
* Anchor Smash reduces base damage, which is the majority of Phantom Lancer's auto-attack damage.
* An 
Aghanim's Scepter upgraded Gush slows down and reduces all of Phantom Lancer's illusions.
Additional:
* A dozen of Phantom Lancer's illusions with all their might can barely hurt Tidehunter at all thanks to Kraken Shell and Anchor Smash. The only way Phantom Lancer can hurt Tidehunter is through the mana burn provided by 
Diffusal Blade.
* Even with high chasing power from 
Spirit Lance and 
Phantom Rush (and even Diffusal Blade), Tide Hunter can shrug it all off with Kraken Shell and escape by using a 
Town Portal Scroll or just moving away.
* The AoE nukes from Ravage, Anchor Smash, and an Aghanim's Scepter-upgraded Gush can clear Phantom Lancer's illusions easily.
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.
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.
Lycan
* Mirana's Leap is ineffective if Lycan uses Shapeshift. It also allows him to dodge Sacred Arrow.
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.
Tidehunter
* Ravage damages and disables Chaos Knight and his illusions.
* Anchor Smash deals respectable area damage, especially to Phantasms and lowers Chaos Knight's damage output.
* Kraken Shell dispels Chaos Bolt and Reality Rift while providing protection from damage.
Tidehunter
* Tidehunter is a core builder of Pipe of Insight. Along with natural high health pool, it's tough to burst the Leviathan down.
* Kraken Shell thwarts long disables attempts if Tidehunter receives enough damage.
* Gush and Ravage long cast and reach ranges will effortlessly hit 
Lion, either bursting him down or making him extremely vulnerable and worn in matter of seconds.
Tidehunter
* Gush can make Crystal Maiden's already weak armor even weaker.
* Kraken Shell can dispel Frostbite, preventing him from getting stuck inside Freezing Field.
* Ravage is very useful for interrupting Freezing Field, even while Crystal Maiden is under the effects of 
Glimmer Cape. Crystal Maiden must purchase a Black King Bar, which is far more costly.
Tidehunter
* Kraken Shell dispels both Shadowraze's damage amplification stacks and Requiem of Soul's damage reduction (provided Tidehunter has taken enough damage).
* Ravage cancels Requiem of Souls if Shadow Fiend isn't protected by Black King Bar.
Additional:
* Kraken Shell dispels the damage amplification stacks of 
Shadowraze as well as the damage reduction from 
Requiem of Souls (provided he has taken enough damage).
* Anchor Smash reduces Shadow Fiend's large attack damage, Kraken Shell makes Tidehunter the last target Shadow Fiend wants to attack.
* Ravage can easily cancel Requiem of Souls if Shadow Fiend isn't protected by Black King Bar.
Tidehunter
* Kraken Shell can dispel Dismember after reaching a certain threshold of damage.
* Tidehunter's naturally high health, strength gain, and common itemization for survivability through magic resistance makes Tidehunter a poor target.
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 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.
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
* 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.
Tidehunter
* Ravage, being an AoE disable, cancels Epicenter's channeling from a long range, limiting his potential to counter-initiate.
* This can be remedied, however, by first using a Black King Bar, then channel Epicenter, then finally initiate with 
Blink Dagger.
Tidehunter
* Tidehunter takes close to no damage from Undying's zombies once he maxes out his Kraken Shell, especially if he gets the level 20 Kraken Shell upgrading talent. This might allow him to blink away to safety.
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.
Tidehunter
* Kraken Shell makes Tidehunter take nearly no damage from Spiderlings.
* Anchor Smash kills Spiderlings in one or two casts, should Broodmother try to swarm Tidehunter with them.
Tidehunter
* Vengeful Spirit should carefully consider whether to use her Nether Swap on Tidehunter, as it can easily position him for a Ravage on Vengeful Spirit and her allies.
* Due to Magic Missile's high damage, Kraken Shell will often proc and clear Tidehunter's debuffs.
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.
Tidehunter
* Visage's Familiars cannot penetrate Kraken Shell and will do almost no damage to Tidehunter even with 
Medallion of Courage or 
Solar Crest.
* Anchor Smash's bonus damage has the potential to kill Familiars.
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 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.
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
Tidehunter
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: 
Sven, Omniknight, Enigma, Luna, Naga Siren, 
Mars, Jakiro, 
Venomancer, 
Elder Titan, Faceless Void, 
Rubick, 
Keeper of the Light, Pugna, Invoker, 
Spectre, Alchemist, Treant Protector, 
Lina, 
Oracle, 
Zeus, Shadow Shaman, 
Phoenix, 
Razor, 
Huskar, 
Batrider, 
Kunkka, Tidehunter, Wraith King, 
Sand King, 
Medusa, 
Dawnbreaker.
Tidehunter
* Most summons and illusions can barely hurt Tidehunter at all, after their attacks get reduced by Anchor Smash and blocked by Kraken Shell: Nature's Prophet, Enigma
* Also Ravage's large area of effect and damage can easily damage all those units at once, or just straight up clear them.
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.
Tidehunter
* Tidehunter's Kraken Shell dispels Corrosive Haze and Bash of the Deep's stun if enough damage is taken. Anchor Smash and Kraken Shell's damage block also reduces Slardar's damage.
Tidehunter
* Riki doesn't deal burst damage.Durable heroes (
Axe, Tidehunter etc.) will usually survive a jump from him,move out of Smoke Screen and potentially retaliate.
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.
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.
Tidehunter
* Heroes who can stun multiple units at once: 
Dark Willow, Spirit Breaker, Slardar, Invoker, and Tidehunter.
Tidehunter
* Heroes that excel at grouping up with their team very early will be able to take advantage of a Clinkz that tries to pick off heroes that are alone: Brewmaster, 
Dazzle, Tidehunter.
Tidehunter
* Tidehunter with Kraken Shell when damage received reaches the threshold.
* Heroes that can remove the Track debuff with their skills:
* 
Abaddon with 
Aphotic Shield and 
Borrowed Time
* Huskar with 
Life Break
* 
Juggernaut with Blade Fury
* 
Legion Commander with 
Press the Attack
* Lifestealer with 
Rage and 
Infest
* Naga Siren with 
Mirror Image
* Omniknight with 
Heavenly Grace
* Oracle with 
Fortune's End and 
False Promise
* Phantom Lancer with 
Doppelganger
* Slark with 
Dark Pact
* Ursa with 
Enrage
* Weaver with 
Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Lycan
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Lycan
* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.
Lycan
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, 
Bloodseeker, Anti-Mage, 
Timbersaw.
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.
Tidehunter
* Heroes with low mana pools (eg.Doom andTidehunter) will feel the effects of Silencer's Intelligence Steal far more than others.
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
* 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.
Tidehunter
* Kraken Shell dispels 
Dual Breath, 
Ice Path, 
Liquid Frost, 
Liquid Fire and even 
Macropyre's Burn.
* It also completely negates the damage from Liquid Fire and Ice path, while heavily reducing the damage from all of his other abilities
* Jakiro is a naturally slow hero, Gush will allow you to easily catch him, while also reducing his Armor
Tidehunter
* Positioning-reliant heroes (
Windranger, Tidehunter, Ursa...), since Earth Spirit can disrupt positioning with his Boulder Smash.
Lycan
* Shapeshift allows Lycan to chase down Earth Spirit.
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.
Tidehunter
* Durable heroes: Axe, Dawnbreaker, Bristleback, Mars, Omniknight, Tidehunter, Wraith King, 
Primal Beast, 
Underlord.
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.
Lycan
* Phantom Assassin's 
Blur is a real problem for Lycan, as he relies entirely on direct attacks to deal damage.
Tidehunter
* Heroes such as 
Lone Druid, Tidehunter and 
Viper can be very problematic for Phantom Assassin because they give her very little time to farm and become scary.
Lycan
* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.
Tidehunter
* Melee heroes who may struggle to get close to Sniper: Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Lycan
* You can easily kill a squishy Sniper, due to your high movement speed and his lack of escape.
Lycan
* Keeper of the Light has a blind, which causes Lycan to miss his attacks.
Lycan
* Heroes with hastes: Dark Seer, Lycan
Tidehunter
* Ravage's travel time allows Nyx Assassin to easily stun Tidehunter with 
Spiked Carapace.
* 
Vendetta can instantly deplete Tidehunter's low mana pool, especially in the early game, potentially preventing Tidehunter from casting Ravage.
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
* Paralyzing cask bounces between him and his wolves, keeping him stunned for long amounts of time.
Tidehunter
* Kraken Shell dispels the stun from Paralyzing Cask. However, it does not dispel the damage from Maledict.
* Once Witch Doctor first uses his Death Ward in team fights, Tidehunter can simply cancel it with Ravage, turning the tables against him, especially if Witch Doctor does not have a Black King Bar.
* As a precaution, Witch Doctor should let Tidehunter use Ravage first before channeling Death Ward to turn a team fight in his favor.
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.
Tidehunter
* Tidehunter's Anchor Smash will cripple all of Enigma's Eidolons, and at a higher level, Tidehunter will be capable to instantly kill the whole group of them for a boost of gold.
* Kraken Shell negates Eidolons's damage and Enigma's auto attacks, making laning against Tidehunter nearly impossible for Enigma.
* Ravage has an insane radius, and considering that Enigma is prone to waiting around for a Blink Dagger and Black King Bar combo, Ravage's stun may catch Enigma off guard and put Blink Dagger on cooldown, limiting him a crucial teamfight time.
Tidehunter
* 
Fury Swipes will keep stacking on Tidehunter since it cannot be dispelled by Kraken Shell and its bonus damage cannot be reduced by Anchor Smash.
* Enrage dispels the slow from Gush, and if upgraded with Aghanim's Scepter, can even dispel Ravage's stun.
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.
Tidehunter

Dark Pact dispels debuffs from Gush, Anchor Smash and even Ravage if timed correctly.
Essence Shift or dispel the leash if he gets 
Pounced.
* Kraken Shell cannot restore attributes stolen by
