* Abaddon could punish Chaos Knight for using his Phantasm and Reality Rift combo on him with Aphotic Shield. Additionally, it provides extra protection against Chaos Knight's potential to take Abaddon down quickly.
* Furthermore, Abaddon's Borrowed Time makes it utterly impossible to burst Abaddon down, effectively reducing the amount of targets Chaos Knight can threaten by 1 for the entire game.

* Abaddon can activate Borrowed Time to dispel Dismember; breaking the disable and potentially allowing Abaddon to escape.
* Aphotic Shield can be cast on an ally to dispel the stun of Dismember, which can make kills difficult to secure, given that Dismember is Pudge's only reliable disable.
* Pudge lacks a mobility without a Blink Dagger, causing him to be easily chased with Curse of Avernus. The silence also prevents him from toggling off his Rot.

* If Meat Hook is used before Blink, Anti-Mage may be able to escape Pudge's grasp by blinking safety.
* Counterspell grants Anti-Mage a large degree of magic resistance, a damage type Pudge is highly reliant on to secure kills. This make Anti-Mage a bad target for Pudge. The active can also block Dismember if timed correctly.
* Mana Break can quickly drains Pudge's low supply of mana, which may render Meat Hook & Dismember unusable and making him a prime target for Mana Void.

* Anti-Mage commonly builds Battle Fury, which can deal with Phantasm illusions easily.
* Counterspell, if timed right, will turn Chaos Bolt against the Knight, and can set up for a kill if he is not careful.
* Even if Counterspell is on cooldown, Blink can almost always dodge a Chaos Bolt because of its slow projectile.
* Mana Break will quickly drain Chaos Knight's mana.
* Beware, however, Anti-Mage is fairly fragile and cannot withstand heavy incoming physical damage at any points in the game, which Chaos Knight excels at. A good player will bait out Counterspell, and retaliate once it's over.

* Pudge is particularly susceptible to Bristleback's Viscous Nasal Goo and Quill Spray due to his naturally low armor & poor agility gain.
* Bristleback, in combination with his strength gain, high health, common itemization for magic resistance and damage reduction from Bristleback makes him a poor target for Pudge.
Additional:
* Bristleback is one of the hardest heroes to gank with a Meat Hook and Dismember combo, and attempts to do so sometimes backfire on Pudge.

* Quill Spray quickly destroys Chaos Knight's Phantasms.

* Wukong's Command and Boundless Strike combo can easily cause havoc on Chaos Knight by destroying all of his powerful illusions.
* Chaos Knight without Phantasm cannot deal with Jingu Mastery at all.

* Tree Dance has a low cooldown and allows Monkey King to jumps on trees quickly, making him a difficult target to hook.
* Because of his low attack speed and poor agility, Monkey King can inflict a large amount of damage quickly by Jingu Mastery.
* Boundless Strike interrupts Pudge's Dismember from a long range.
Additional:
* Monkey King can scout Pudge's positioning from the trees, making it easier for him and his allies to dodge Meat Hook
* Monkey King doesn't care about Dismember if he has already casted Wukong's Command, his soldiers will do short work of Pudge's low armor
* If someone else target is targeted by Dismember, Boundless Strike can easily cancel its channeling from afar

* Gush reduces Pudge's armor which he already lacks.
* 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 make Tidehunter a poor target.

* Ravage damages and disables Chaos Knight's army.
* Anchor Smash deals respectable area damage at early levels and lowers Chaos Knight's damage.
* Kraken Shell dispels Chaos Bolt and Reality Rift while providing protection from damage.

* The percentage-based primary-attribute reduction effect of Whirling Death can be devastating for Pudge due to his high strength gain through Flesh Heap.
* Reactive Armor's health regeneration and common itemization for magic resistance and durability make Timbersaw a poor target for Pudge.
* Timber Chain's high mobility makes Timbersaw difficult to lockdown for Pudge, given he only has one reliable disable.

* Strong area damage, particularly from Whirling Death and Chakram, lets Timbersaw clear out illusions quickly.
* Whirling Death directly reduces Strength from both Chaos Knight and his Phantasm illusions, reducing both the damage output and raw health that the hero relies on.
* Reactive Armor quickly builds stacks against Phantasm illusions, making Timbersaw hard to kill.
* Timber Chain allows Timbersaw to escape while surrounded.
* Timbersaw should be careful if Chaos Knight manage to farm a Bloodthorn however, as it can silence Timbersaw on a whim, rendering him useless for a lengthy duration.
Additional:
* Reactive Armor helps Timbersaw to endure the damage from Chaos Bolt and Reality Rift combo.
* Timbersaw's large amount of pure damage AoE nukes clears Chaos Knight's illusions quickly, drastically reducing his damage.

* Arcane Orb and Sanity's Eclipse quickly drains Pudge's limited mana pool, making him unable to use Meat Hook or Dismember and also bypasses Flesh Heap.
* Outworld Destroyer can save allies or himself caught by Dismember or Meat Hook with Astral Imprisonment.

* Illusion based heroes (like Chaos Knight and Terrorblade) can't use their illusion beneficially against Sanity's Eclipse's high AoE burst damage.

* Chaos Knight's single target abilities are difficult to target against Phantom Lancer's illusions.
* Chaos Knight's lack of mobility makes him an easy target for Phantom Lancer to Phantom Rush and drain his already low mana pool.
Additional:
* Juxtapose allows Phantom Lancer to overwhelm Chaos Knight due to his single-target abilities.
* Doppelganger can be used to dodge Chaos Bolt.
* Spirit Lance can be used to harass Chaos Knight during the early game.
* Since Phantom Lancer builds Diffusal Blade often, it can quickly drain Chaos Knight of all his mana, leaving him unable to cast spells.

* Heroes with many summons or illusions are much harder to catch with Meat Hook: Nature's Prophet, Phantom Lancer, Chen.

* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.

* Echo Slam's damage potential increases due to Chaos Knight's Phantasm illusions.
Additional:
* Echo Slam will deal a colossal amount of damage to your army, as will Fissure at lower levels.
* The area stuns from Aftershock will always slow down your illusions, since they can't have spell immunity.
* Earthshaker should not attempt to fight back a full slotted Chaos Knight however, since he will be completely obliterated by Chaos Knight's colossal damage output, even if he managed to land an Echo Slam

* As long as Windranger is able to identify the real hero among the illusions, heroes relying on them can be easily tagged with Focus Fire: Chaos Knight, Terrorblade, Phantom Lancer, Naga Siren.

* Pudge relies on his hook to initiate his combo. As long as she's able to avoid the hook with Windrun and shackle him, Windranger can take him down easily. Pudge's low armor means that he won't be able to endure Focus Fire for long.

* Heroes who are reliant on illusions or summons: Chaos Knight, Broodmother, Naga Siren.

* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: Bane, Pudge, Witch Doctor, Crystal Maiden, Enigma.

* Heroes with high health especially Strength heroes will take more damage on Sun Ray: Axe, Pudge, Bristleback, Mars.

* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix

* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix

Additional:
* Ember Spirit is evasive and can dodge close encounters with melee heroes like Chaos Knight. Ember Spirit can't be caught with the slow from Reality Rift, and Flame Guard and Sleight of Fist can bring Phantasm's illusions down quickly.

* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.

* Tether and Overcharge makes it much harder for Pudge to kill a target with Meat Hook, and Relocate can save the Io's ally while Dismember is being channeled.

* Shukuchi grants Weaver invisibility and a high degree of mobility for a short time, which can make Weaver a difficult target to hook.
* The Swarm with Desolator can remove Pudge little natural armor and makes it difficult to remove Weaver's beetles, due to his low base attack time and poor agility. Additionally, The Swarm can scout out Pudge's location.
* Given that Pudge only has one reliable disable in Dismember, should Weaver survive, Weaver can simply use Time Lapse (or target allies with Aghanim's Scepter) to remove the damage entirely.
Additional:
* While Weaver is in Shukuchi, Rot doesn't slow him and Meat Hook is easy to avoid.
* Even when hooked, Weaver can use Time Lapse, negating both the damage and displacement.
* Pudge has low armor and low attack speed, making him susceptible to The Swarm and physical attacks.
* Dismember is easy to block with Linken's Sphere and it's the only way to break Weaver's Linken Sphere.
* However, the long duration stun of Dismember can be dangerous for Weaver.

* With his AoE damage, Jakiro can easily kill Chaos Knight's Phantasm illusions.
* Chaos Knight usually doesn't buy a Black King Bar, making him vulnerable to an Ice Path into Macropyre combination.
Additional:
* Ice Path and Macropyre punish Reality Rift with a long stun and heavy damage across all illusions.

* Storm's Dispel Magic combined with Thunder Clap deals high damage against Chaos Knight's illusions even in the late game.
* Chaos Knight's reliance on physical damage is easily hindered by Drunken Brawler.
* Chaos Knight's lack of area effect and mobility makes him easily overwhelmed by Primal Split.
Additional:
* Dispel Magic from {U:Storm} can instantly kill the Phantasm army early on, and can still deal a lot of damage to them late game, revealing the real Chaos Knight.

* Heartstopper Aura is effective against high health heroes, and Pudge is no exception. Coupled with his constant self-damage from Rot, being around Necrophos could prove risky for an overconfident Pudge.
* Regardless of how much health Pudge gains through Flesh Heap, Reaper's Scythe will often kill Pudge should his health fall below 40%, making Necrophos an ideal counter versus Pudge.
Additional:
* No matter how high Pudge builds up strength with his Flesh Heap, all it needs is for him to fall below a certain percentage of health for him to fall to Reaper's Scythe. Considering his constant self-damage with Rot, being around Heartstopper Aura will prove risky for an overconfident Pudge.

* Heroes that have high health but little to no magic resistance are easy prey for Necrophos, as no matter how high they build their health up, Reaper's Scythe will kill them outright as long as they fall under a certain threshold, and Heartstopper Aura will deal the same amount of damage regardless, decaying their health the longer they stay within range. As such, Strength heroes like Chaos Knight, Centaur Warrunner or Magnus are good targets for his ultimate.

* Earth Spirit can easily disrupt Dismember because he can disable from a long distance with a Stone Remnant and Rolling Boulder. With talent he can even pull his teammates out of Dismember and also silence Pudge with Geomagnetic Grip.

* Cold Embrace protects targets of Reality Rift.
* Winter's Curse turns Phantasm illusions against Chaos Knight or a teammate.
* Splinter Blast deals decent area damage to Phantasm illusions.
* Arctic Burn's percentage-based damage quickly wears down Chaos Knight's health.
Additional:
* Winter Wyvern can make Chaos Knight's illusions attack the real one, provided the player knows who it is.
* Alternatively, Winter's Curse can make Chaos Knight and all his illusions attack one of his allies.
* Cold Embrace protects ally who is focused by Chaos Knight.
* Splinter Blast deals decent area damage to Chaos Knight's illusions.

* Phantasms can be easily killed with Purification.
* Heavenly Grace dispels the stun from Chaos Bolt and the armor reduction from Reality Rift.

Additional:
* Purification heals a teammate targeted by Reality Rift and heavily damages Chaos Knight and his illusions in the process.
* Guardian Angel blocks all of Chaos Knight's damage for a duration.

* Mana Burn completely drains Pudge's little mana which may render Meat Hook & Dismember unusable.
* Impale and Spiked Carapace used to cancel Dismember if timed perfectly.
* Vendetta grants Nyx Assassin invisibility and a high degree of mobility for a long time, which can make Nyx a difficult target to hook. In addition, it also scouts out Pudge's location and surprising him with his attack, Impale and Mana Burn.

* Corrosive Haze lowers armor and reveals Pudge's location, making it hard to use Meat Hook on Slardar's teammates or Slardar himself.
* Because Corrosive Haze also reduces armor, it amplifies Bash of the Deep's damage.
* Slithereen Crush interrupts Pudge during Dismember at close range.
* Guardian Sprint allows Slardar to avoid Meat Hook.
Additional:
* While Slardar has Guardian Sprint activated, Rot cannot slow him and Meat Hook is easier to avoid.
* Slithereen Crush allows Slardar to interrupt Dismember at close range (when Slardar is not a target).
* Corrosive Haze reveals Pudge's location, making it very difficult for him to land hooks from the fog.

* Shallow Grave can be used to save an ally during Dismember and Rot.
* A combination of Bad Juju, Poison Touch, and items like Desolator or Solar Crest can tear off Pudge's low armor, making him even more vulnerable to physical damage.

* Flak Cannon destroys Chaos Knight's illusions very quickly.

* Dragon Blood's armor bonus greatly reduces the damage dealt by Phantasm.

* Lich's Chain Frost, especially after obtaining its respective talent that provides unlimited bounces, can take out all of Chaos Knight's illusions quickly.
* An Aghanim's Scepter-upgraded Sinister Gaze can hypnotize Chaos Knight and his illusions while also draining his already low mana pool.

* Berserker's Call and Counter Helix makes short work of Chaos Knight's Phantasms.
Additional:
* Berserker's Call allows Axe to lock down Chaos Knight and his illusions.
* Counter Helix combined with Blade Mail clears illusions out in no time.

* Tidebringer, Torrent and Ghostship destroys Chaos Knight's Phantasm army all through the game.

* Using Reality Rift sets up a Reverse Polarity on Chaos Knight and his illusions.
* Shockwave and Skewer kill Phantasm's illusions quickly, as can Empower cast on a melee carry.
Additional:
* All Magnus abilities are very good against Chaos Knight's Phantasm illusions.

* Pudge has low armor and low mobility, making him a prime target for Terrorblade's right-clicks.
* Meat Hook is a lot harder to land on the real Terrorblade if he has illusions around him.
* Because Dismember targets only one hero, Terrorblade's illusions can potentially save the real Terrorblade if he's caught in it.

* Great Cleave is very effective against Chaos Knight's illusions.
* Storm Hammer's radius can catch all of Chaos Knight's illusions at once, especially after Reality Rift.
* Warcry shields Sven and his teammates against Chaos Knight's burst physical damage.

* Warcry's armor bonus counteracts Reality Rift's debuff and reduces Chaos Knight's damage output.
* Great Cleave and God's Strength devastates Phantasm illusions.

* Untouchable makes all of his attacks slow therefore he is unable to deal damage, especially his critical damage of Chaos Strike, also enables you to escape easily from his attacks.
* Reality Rift is still a danger because he can decrease a good amount of armor, making it dangerous because of her little armor stat
Additional:
* Untouchable will definitely slow all of your attack animations making you unable to deal any damage especially critical damage from Chaos Strike.

* Heroes who are reliant on illusions: Chaos Knight, Phantom Lancer, Naga Siren.

* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.

* Because of his massive AoE damage, Sand King is very effective against illusion heroes: Chaos Knight, Phantom Lancer, Terrorblade,...

Additional:
* Sand King's massive area damage output, particularly Epicenter, allows him to quickly take down Chaos Knight and his illusions.
* He can apply Caustic Finale to illusions with attacks for extra damage.

* High health heroes like Pudge and Undying gain strength by using abilities. Focusing them with Spirit Siphon can let you heal more health and deal more damage to them.

* Illusion-based and multi-unit heroes can take advantage of Chaos Knight's lack of area damage: Naga Siren, Phantom Lancer, Broodmother

* One of Lion's level 20 talents lets Mana Drain affect 2 secondary targets. This can make things difficult for heroes like Phantom Lancer, Chaos Knight, and Terrorblade who rely on illusion armies.
* Mana Drain and Hex instantly kill any illusions. Finger of Death upgraded with Aghanim's Scepter also shreds most illusions.
* One of Lion's level 20 talents lets Mana Drain affect 2 secondary targets. This can make things difficult for heroes like Phantom Lancer, Chaos Knight, and Terrorblade who rely on illusion armies.

* However, Death Ward is easily interrupted by Chaos Bolt until Witch Doctor buys Glimmer Cape or Black King Bar.

* Doom disables the toggling of Rot and, if cast at the right time, may leave Pudge with a potentially lethal health drain.
* Doom's naturally high health, strength gain and damage output makes him a poor target for Pudge.
* The damage of Doom's Infernal Blade scales with the target's maximum health, which is particularly effective against Pudge due to his naturally high health and further health granted by stacks of Flesh Heap.
Additional:
* Infernal Blade deals high damage to Pudge due to his high strength grow with Flesh Heap.
* Using Doom with timing against Pudge who had just activated Rot would usually kill him.
