* 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.

* Phantasm's illusions make it difficult to land Meat Hook and Dismember.
* Chaos Bolt is a comparatively low cooldown tool to interrupt Dismember.

* Beside Inner Fire, Huskar has no reliable AoE ability to clear Phantasm illusions.
* Huskar likes to fight at low health to benefit from his Berserker's Blood, thus vulnerable to Chaos Knight's high burst physical damage.

* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle, Abaddon

* Dark Pact is minimally effective against Phantasm illusions, and Slark lacks area damage otherwise.
* Pounce can be counteracted by Reality Rift.

* Phantasm dispels Ignite and makes targeting the real Chaos Knight much harder.

* Heroes with illusions and summons can swarm Bane, who has no area abilities: Broodmother, Chaos Knight, Nature's Prophet, Phantom Lancer, Terrorblade.

* Bane lacks mobility, therefore becoming helpless when silenced by Curse of Avernus.

* Skywrath mage also has a terrible time fighting against anything that isn't a hero.

* Aphotic Shield removes silences, slows and stuns, possibly foiling a full-duration Mystic Flare.
* Borrowed Time makes it impossible to burst Abaddon down, even healing him up due to Mystic Flare's damage.

* Aphotic Shield can nullify Chen's combo, while clearing Chen's creeps simultaneously.

* Heroes who can negate effects of Sunder: Faceless Void's Time Walk, Weaver's Time Lapse, Broodmother's Insatiable Hunger, Abaddon's Borrowed Time and Troll Warlord's Battle Trance can nullify Sunder.

* Chaos Knight can easily kill a lone Techies before they Blast Off!.

* Because they explode in very short intervals, a stack of Remote Mines will always trigger Borrowed Time, making them impossible to kill Abaddon unless his resistances are lowered enough or Abaddon is affected by Break.
* Abaddon can easily dispel the long-lasting root of Stasis Trap on himself and on an ally, while at the same also providing protection against the other mines' damage.
Additional:
* Borrowed Time's automatic activation will help Abaddon survive a field of Proximity Mines or a Blast Off combo. However, the damage from a single mine can kill him if his HP is low enough.
* Aphotic Shield's can easily break Techies' Etheral Blade combo.

* While Chaos Knight can land far away from Rubick due to Telekinesis, it can be counteracted by Reality Rift.
* Phantasm dispels Fade Bolt's damage reduction debuff.
* Rubick is fragile and can easily be killed by Chaos Knight and Phantasm's illusions, before he retaliates.

* Chaos Knight's high health pool makes him resistant to Zeus' burst damage. Phantasm can dispel Veil of Discord, a typical item purchased by Zeus.
* Zeus is easily overwhelmed by Chaos Knight's strong illusions, as Arc Lightning is not enough to kill them fast enough to have any impact.
* Zeus' low base armor makes him extremely vulnerable to Chaos Knight's high damage output and armor reduction.

* Chaos Knight often buys Bloodthorn, rendering Morphling useless for 5 seconds (unless he has Linken's Sphere or Manta Style )

* Abaddon's constant heals and protection can save himself and his allies from burst-focused heroes, such as Legion Commander, Faceless Void, and Pudge.

Additional:

Additional:
* Sticky Napalm, Flaming Lasso, and Flamebreak can all be instantly dispelled by Aphotic Shield.
* Firefly will continuously heal Abaddon under Borrowed Time.

* Sniper has no innate ability to deal with Phantasm or escape a Reality Rift and Chaos Bolt combo.

* Phantasm can be used to dispel Earthshock's slow. Manta Style is another item that counter Ursa greatly.
* Ursa has low mobility, once jumped on by Reality Rift, Ursa struggles to escape.

* Chaos Bolt's potentially long stun with Chaos Bolt gives Ursa little opportunity to Enrage.

* {Ability ID:Spirit Siphon|Death Prophet} will continuously heal Abaddon under Borrowed Time, for a percentage of his maximum health.

* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
