* 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.

* 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.

* Borrowed Time makes Abaddon nearly impossible to gank.
* Aphotic Shield and Mist Coil prevents Bloodseeker from gaining his Thirst bonuses.
Additional:
* If Rupture is used on Abaddon, Abaddon can use Borrowed Time and easily heal for the duration of Borrowed Time by simply moving.

* Borrowed Time can give Abaddon a second chance after a Black Hole combo.
* Aphotic Shield can be used to save allies or Abaddon himself from Malefice.
* Abaddon can easily heal himself as well as his allies during a team fight, especially with Aghanim's Scepter upgraded Borrowed Time.

* Snowball negates Rupture and protects Tusk allies when Ruptured.

* Walrus PUNCH! can interrupt Black Hole and it can pierce spell immunity and neither Black King Bar nor Linken's Sphere can protect Enigma from Walrus PUNCH! as Walrus PUNCH! is an auto-cast ability.
* In pretty much any phase of the game, Tusk's abilities can easily cancel Black Hole and disrupt Enigma's positioning.

* Storm Spirit is invulnerable during Ball Lightning, allowing him to zip away from any ganking attempts with Rupture.
* Ball Lightning also prevents Bloodseeker from chasing down an injured Storm Spirit, or catching him in Blood Rite.
Additional:
* Storm Spirit is invulnerable during Ball Lightning, rendering Rupture ineffective against him.

* An isolated Enigma in the early game can be easily killed by Storm Spirit thanks his higher mobility and dueling potential. However, Storm Spirit can be killed when caught by Enigma's full combo, especially if Enigma has Black King Bar.
* Storm can kill all of Enigma's Eidolons relatively quickly without much risk, slowing down Enigma's farming speed, preventing him from split pushing, and giving Storm its considerable bounty, especially if Enigma chooses the Level 25 Talent that gives him more Eidelons.
* Storm can zip through Black Hole stunning Enigma while he's channelling until Enigma buys Black King Bar.

* Mana Shield makes it very difficult for Bloodseeker to gain his Thirst bonuses.
* Rupture rarely kills Medusa through Mana Shield.

* Medusa's Split Shot can make quick work of Enigma's Eidolons and take advantage of their considerable bounty.
* Medusa can also kill Eidolons with her Mystic Snake that can also greatly damage Enigma and drain some of his mana.
* If Medusa activates Stone Gaze at the start of a fight, it can make initiating and landing an effective Black Hole exceedingly difficult, because Stone Gaze can cancel Enigma's Black Hole even through spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.
Additional:
* Medusa's Split Shot can make quick work of Enigma's Eidolons and take advantage of their considerable bounty.
* If Medusa activates Stone Gaze at the start of a fight, it can make initiating — and landing an effective Black Hole exceedingly difficult. Stone Gaze can cancel Enigma's Black Hole even through spell immunity, which can discourage Enigma from initiating with Black Hole.

* Heroes with disables that go through spell immunity can end Bloodseeker before he has the chance to do anything: Batrider, Beastmaster

* Long ranged disables, especially those that pierce spell immunity, cancel Black Hole: Beastmaster's Primal Roar, Bane's Fiend's Grip, Faceless Void's Chronosphere, Magnus's Reverse Polarity, Axe's Berserker's Call, Pudge'sMeat Hook.

* Laser blinds Bloodseeker, preventing him from getting last hits and denies during the laning stage and preventing him from finishing off enemies.
* Tinker always buys Boots of Travel, helping him escape Bloodseeker's early ganks.
* Tinker's heavy magical damage will burst down Bloodseeker during the early to mid game, as he has little health.
Additional:
* Laser can be very effective against Bloodrage as the damage will be amplified while the blind prevents Bloodseeker from landing hits.
* Keen Conveyance guarantees him escape from Rupture.

* Astral Imprisonment can save allies from a Black Hole combo. When upgraded with Aghanim's Scepter and Aghanim's Shard, it becomes exceedingly difficult for Enigma to land a good Black Hole against Outworld Destroyer and his team.
* Astral Imprisonment can also cancel Black Hole while Enigma does not have Black King Bar.
* Arcane Orb and Sanity's Eclipse can often make a short work out of Enigma and his Eidolons.

* Broodmother can kill Enigma's Eidolons with Spawn Spiderlings, and spawn her spiderlings in their place. But remember that Enigma can do the same to Broodmother's spiderlings with Demonic Conversion and Midnight Pulse.
* Without the protection from Black King Bar, Broodmother can cancel Enigma's Black Hole with Bloodthorn and make him more vulnerable to damage. Broodmother can also buy Abyssal Blade to cancel Enigma's Black Hole even through Black King Bar.
* Silken Bola causes Enigma's attacks to miss a lot and renders him more vulnerable to magical damage. And if Broodmother takes 400 AoE Silken Bola, then she will be able to use to cause Enigma's Eidolons to miss their attacks as well. In addition, Enigma does not like to buy items to provide him true strike such as Bloodthorn, Monkey King Bar, Witch Blade and it's upgrade Revenant's Brooch.
* If Broodmother is lucky enough to survive being trapped in Black Hole, she will be able to recover her lost health with Insatiable Hunger.
* Aghanim's Scepter gives Broodmother access to Spinner's Snare, which allows her to create invisible lines on her webs from Spin Web that will root Enigma, deal damage over time to Enigma and reveal Enigma if he unwittingly steps on them, disrupting his attempts to initiate with Black Hole, prevent him from using Blink Dagger, while also alerting Broodmother on his attempts to ambush her and her allies.
Additional:
* Broodmother can kill Enigma's Eidolons with Spawn Spiderlings, and spawn her spiderlings in their place. But remember that Enigma can do the same to Broodmother's spiderlings with Demonic Conversion and Midnight Pulse.

* Berserker's Rage will repeatedly trap Bloodseeker in a one-on-one fight.
* Whirling Axes (Melee) blinds Bloodseeker, causing him to miss 60% of the time, and therefore reduces his ability to gain the upper hand in teamfights.

* Fissure does a great job at interrupting Black Hole immediately, especially with Blink Dagger and Aether Lens.
* Echo Slam's damage potential increases due to the eidolons created by Demonic Conversion.

* Haunt can ruin Enigma's initiation with Blink Dagger, no matter where he is on the map.
* Spectre often buys Radiance, which allows her to deal damage over time to Enigma and put Blink Dagger on cooldown.
* Dispersion reflects the damage of Midnight Pulse and Black Hole inflicted back to Enigma. This can get even worse for Enigma if Spectre buys Blade Mail.
* All of Spectre's abilities ignore spell immunity, which means that even with Black King Bar, Enigma has absolutely little to no chance against Spectre at any stage of the game.

* Arcane Curse can be cast from a long range to put Enigma's Blink Dagger on cooldown.
* Global Silence can interrupt Enigma's Black Hole channeling through Black King Bar and Linken's Sphere, making Silencer one of Enigma's hard counters. But bear in mind that Global Silence can be dispelled with Black King Bar if activated first.
Additional:
* Silencer can easily ruin Enigma's initiation, as Global Silence cancels Black Hole, even through Black King Bar and Linken's Sphere.

* Chaotic Offering's spell immunity piercing stun can stop Black Hole's channeling. Due to this ability's large area of effect, it can be cast at a safe distance from the Black Hole. It also goes through Black King Bar and ignores Linken's Sphere.
* Fatal Bonds and Aghanim's Shard upgraded Shadow Word can be used to make Enigma's Eidolons easier to kill, potentially feeding the enemy team. Also,their constant damage will put Blink Dagger on cooldown, potentially forcing Enigma to prematurely activate Black King Bar.
Additional:
* Chaotic Offering pierces spell immunity and is an area of effect ability, therefore it doesn't matter if Enigma buys Black King Bar or Linken's Sphere, Warlock will always be able to cancel the channeling of Black Hole.
* Enemies often get clumped up around Black Hole to hit your allies, giving you a perfect opportunity to cast Fatal Bonds, Chaotic Offering, and Upheaval on multiple enemies.

* Voodoo Restoration heals to counter Bloodseeker's Thirst.
* Rupture is generally useless against Witch Doctor while he is staying on Death Ward.
* Although Witch Doctor needs to be careful as Blood Rite can interrupt Death Ward.

* Enigma's abilities have a huge mana cost, meaning that Nether Ward will deal a lot of damage to Enigma.
* Pugna can heal allies trapped inside Black Hole thanks to Life Drain, Pugna can also damage multiple of Enigma's allies around him with Life Drain when he casts it on Aghanim's Shard upgraded Nether Ward during teamfight.
* Nether Blast can easily kill Eidolons, especially when Enigma is pushing.
* Even though Pugna cannot cancel Black Hole on his own, smart Pugna can buy Orchid Malevolence to stop Enigma from channeling Black Hole and make him more vulnerable to counter-attacks with Decrepify and Life Drain.
Additional:
* Enigma's abilities have a huge mana cost, meaning that Nether Ward will deal a lot of damage to Enigma.
* Pugna can heal allies trapped inside Black Hole thanks to Life Drain.
* Nether Blast can easily kill Eidolons, especially when Enigma is pushing.

* Time Walk negates Rupture's damage.
* Chronosphere prevents Bloodseeker from running down and picking off weak enemies during teamfights.
Additional:
* Time Walk will not make Rupture deal damage for the distance jumped and can be used to quickly escape from Blood Rite.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Bramble Maze greatly hinders Bloodseeker's ability to run around in teamfights and pick off dying allies.
* Shadow Realm prevents Bloodseeker from attacking dark Willow, allowing her to safely teleport away.

* Winter's Curse, when directly targeted on Enigma, goes through Black King Bar, stopping Enigma's Black Hole channeling. It also turns his team against him, potentially killing him. Even if Enigma gets Linken's Sphere on top of Black King Bar, Splinter Blast can be used to pop Linken's Sphere, and Winter's Curse will stop Black Hole channeling.
* Splinter Blast can be targeted on an eidolon, killing off other eidolons and damaging nearby heroes as well.

* Bristleback's constant harass from Quill Spray will greatly hurt Enigma's laning and kill his Eidolons.
* However, Bristleback has no way of canceling Black Hole at all. And Bristleback is not a hero that goes for disabling items to counter that problem.

* Black Hole while definitely a threat to Drow Ranger, is very hard to land as she likes to keep her distance from allies and enemies alike. And if not caught in it, will kill Enigma very quickly due to his low health.
* Malefice can be removed with a Manta Style.
* Drow Ranger being a fairly low health, high armored agility carry doesn't take much damage from Midnight Pulse as others would.
* Demonic Conversion units die very quickly to Marksmanship or even just regular attacks not far into the game within 2 or 3 hits.

* Hookshot's stun pierces through spell immunity and Enigma's channeling can be easily cancelled from a safe distance, assuming none of his allies are in the way, and the Black Hole is not centered directly on Enigma.
Additional:
* Black Hole requires channelling, making it easy to be interrupted with Hookshot.
* Enigma lacks mobility without a Blink Dagger and also is squishy, making him fall easily when ganked by Clockwerk.

* Without Black King Bar, Luna will be able to cancel Enigma's Black Hole from safe distance with her Lucent Beam or with 0.25s Eclipse Lucent Ministun talent for Eclipse and counter-initiate with Eclipse. This can get even worse for Enigma once Luna gets Aghanim's Scepter and combines it with 0.25s Eclipse Lucent Ministun talent that will allow Luna to use Eclipse from safe distance.
* If Luna chooses to use Eclipse in anticipation right after Enigma jumps in with Blink Dagger, she will be able to kill Enigma before he even gets a chance to use Black Hole.
* Luna commonly buys Satanic, which can help her recover from Enigma's Black Hole in case she survives it.
* Moon Glaives combined with Lunar Blessing can make a short work of Enigma's Eidolons before Luna uses Eclipse.
* Bear in mind, however, that once Enigma gets Black King Bar, Luna will be out of solutions to cancel Black Hole, and going for Abyssal Blade on Luna can be risky due to Abyssal Blade's very short cast range.
Additional:
* Without Black King Bar, Luna will be able to cancel Enigma's Black Hole from safe distance with her Lucent Beam or with 0.25s Eclipse Lucent Ministun talent and counter-initiate with Eclipse. This can get even worse for Enigma once Luna gets Aghanim's Scepter and combines it with 0.25s Eclipse Lucent Ministun talent that will allow Luna to use Eclipse from safe distance.

* Bear in mind, however, that once Enigma gets Black King Bar, Luna will be out of solutions to cancel Black Hole, and going for Abyssal Blade on Luna can be risky due to Abyssal Blade's very short cast range.

* Waveform ignores Rupture's damage, letting Morphling escape unharmed.
* Attribute Shift (Strength Gain) makes it very hard for Bloodseeker to kill Morphling or gain his Thirst bonuses, since Morphling can use it to sustain damage while trading attacks when Ruptured.
* Morphling usually builds Linken's Sphere, which blocks Rupture.
Additional:
* Morphling can escape from Rupture using Waveform.
* Morphling is a typical Manta Style carrier, which can be used to dispel the silence from Blood Rite.

* Doom pierces spell immunity and can prevent Enigma from casting any spells or using items until the duration of the spell depletes, as well as cancelling a Black Hole.
* While Doom can be blocked by a Linken's Sphere, which is a common item on Enigma, Aghanim's Scepter upgraded Doom allows Doom to cast Doom on himself to affect enemies near him, and if Doom can combine this with Blink Dagger, he will be able to jump on Enigma while he is channeling Black Hole. Aghanim's Scepter upgraded Doom can also cancel Black Hole if any of Enigma's allies affected by Doom gets too close to him for it's duration, ignoring both, Black King Bar and Linken's Sphere.

* Fire Remnant allows Ember Spirit to escape while Ruptured.
Additional:
* Fire Remnant allows Ember Spirit to escape Bloodseeker while Ruptured.

* Telekinesis has a longer range than the AoE of Black Hole for the purposes of cancelling it.
* All of Enigma's spells are useful to Spell Steal.
* Malefice is useful for interrupting channeling spells or long cast animations. Its stun duration is also amplified thanks to Spell Steal's debuff amplification.
* Demonic Conversion can be used to push or counter-push a lane.
* Midnight Pulse is useful to block an area or for team fights.
* Black Hole is very easy to steal, as it is a channeled ability. It's also one of the best ultimate abilities for team fights, and it can easily turn the fight around for the enemy team. It also does more damage and has a larger cast range thanks to Arcane Supremacy. A stolen Black Hole can also cancel Enigma's Black Hole.
Additional:
* Enigma's signature Black Hole can be devastating if being stolen and dropped on multiple heroes.
* Black Hole requires channeling. Since Enigma has no other ability to replace his last casted spell during channeling, Rubick can steal Black Hole relatively easily if he stays back.
* Rubick can interrupt Black Hole from Enigma, even with an activated Black King Bar, by casting the spell with Enigma in range with regards to the extra cast range granted by Arcane Supremacy.
* Black Hole can be interrupted by Telekinesis in the early game, giving enough time window to steal the spell.
* Bear in mind that an experienced Enigma will purchase Black King Bar and Linken's Sphere at the same time to prevent Rubick from stealing the spell, yet the extra Linken's Sphere will delay Enigma's power spike, so use it to Rubick's advantage.
* It is advised to build items around Black Hole as Rubick. Aghanim's Shard, Black King Bar , Aghanim's Scepter and even Refresher Orb are all legitimate item choices.
* Malefice is a decent source of damage and stun that helps with ganking. If stolen, it can be used to interrupt Black Hole as well.
* Demonic Conversion helpes with pushing and farming for Rubick.
* Fade Bolt effectively negates damage from Eidolons and helps with counter-pushing.
* Midnight Pulse is a solid skill for farming and teamfight damage, which is further amplified by Arcane Supremacy and talents.
* Unexpected enemy may take the effect of Midnight Pulse as that of Enigma's and soak up damage while unrealized.

* Heroes with illusion and clone abilities may confuse Bloodseeker, causing him to waste time in fights: Phantom Lancer, Chaos Knight, Arc Warden

* Stone Form can easily interrupt heroes with long channeling spells, like Crystal Maiden, Bane, Witch Doctor, or Enigma.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Heroes with area heals prevents Bloodseeker from bringing enemies low, and therefore deny him his Thirst bonuses and health return: Necrophos, Dazzle

* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: Disruptor, Death Prophet, Enigma, Faceless Void, Invoker, Lich, Magnus, Mars, Medusa, Outworld Destroyer, Phoenix, Puck, Queen of Pain, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.

* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: Broodmother, Enigma, Nature's Prophet.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

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

* Heroes with high armor and durability can be exceptionally hard for Bloodseeker to bring down: Dragon Knight, Axe

* Long ranged disables, especially those that pierce spell immunity, cancel Black Hole: Beastmaster's Primal Roar, Bane's Fiend's Grip, Faceless Void's Chronosphere, Magnus's Reverse Polarity, Axe's Berserker's Call, Pudge'sMeat Hook.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Heroes that rely on right-clicks will find themselves unable to damage opponents seriously after being affected by Static Link, like Sven, Bloodseeker, and Juggernaut.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Heroes who build a Black King Bar (or have any sources of spell immunity) to channel abilities/items can still get interrupted by Dismember: Enigma, Juggernaut, Phantom Assassin, Pugna, Elder Titan.

Additional:
* Even with Black King Bar, Pudge's Meat Hook and Dismember can still disable Engima while he is channeling Black Hole as Enigma is a very easy target while channeling Black Hole.
* Pudge's Aghanim's Shard upgraded Dismember and Meat Hook are great ways to save allies from Black Hole.
* Enigma is prone to ganks in the jungle or in the off-lane without proper vision. Pudge can take advantage of Enigma's lack of mobility, and gank him often.

* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw

* Mass summoning heroes: Broodmother, Nature's Prophet and Enigma all have summons Puck can clear clear with Illusory Orb and Waning Rift instantly, due to their summons having low health.

* 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.

Additional:
* 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.

* Heroes with high armor and durability can be exceptionally hard for Bloodseeker to bring down: Dragon Knight, Axe

Additional:
* Bloodseeker's physical damage is unlikely to kill Dragon Knight, and therefore rarely get a chance to recover the large amount of HP from Bloodrage.

* Long range disables are really effective against dangerous area controllers and channeling Heroes, like Enigma, Faceless Void or Crystal Maiden, as it may cancel them or prevent enemies from doing further damage while keeping Lion in a relatively safe distance in the warzone.

* Heroes with disables that go through spell immunity can end Bloodseeker before he has the chance to do anything: Batrider, Beastmaster

* Zeus can break Blink Dagger with his long range abilities and global range ultimate, Thundergod's Wrath.
* Lightning Bolt has a long range and a mini-stun, providing a way for him to cancel Black Hole from safe distances, assuming Enigma doesn't have his Black King Bar.
* Zeus's Aghanim's Scepter grants him Nimbus ability that has a global range and mini-stun, making it an even more effective way to cancel Black Hole before Enigma initiates with Black King Bar.
* Zeus is typically able to position himself at a safe distance from the fight, making him a difficult target to capture in a Black Hole.

* Most of the of Jakiro's damage-over-time abilities put Blink Dagger on cooldown, potentially forcing Enigma to prematurely activate Black King Bar.
* Jakiro's Dual Breath, Liquid Fire, Macropyre and Liquid Frost from Aghanim's Shard can take out Enigma's Eidolons, reduce Enigma's attack speed and put Enigma's Blink Dagger on cooldown.
* Jakiro can easily cancel Black Hole with Ice Path as Enigma is a very easy target while channeling it.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.
Additional:
* Most of the of Jakiro's damage-over-time abilities put Enigma's Blink Dagger on cooldown, potentially forcing him to prematurely activate Black King Bar.
* Jakiro's Dual Breath, Liquid Fire, Macropyre and Liquid Frost from Aghanim's Shard can take out Enigma's Eidolons, reduce Enigma's attack speed and put Enigma's Blink Dagger on cooldown.
* Jakiro can easily cancel Black Hole with Ice Path as Enigma is a very easy target while channeling it.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.

* Shallow Grave prevents Bloodseeker from replenishing his health by finishing off enemies.

* Black Hole is a channeling ability and Earth Spirit has at least two possibilities which can interrupt these kind of spells. Enigma is exposed and cannot move while using Black Hole, thus making it easy for Earth Spirit to stop the feared ability with the huge range of Rolling Boulder and forcing Enigma to quickly rush a Black King Bar to prevent this.
* Enigma is level dependant, squishy and relativly defenseless in the early game and therefore vulnerable to aggressive roam maneuvers in this stage of the game. Earth Spirit excels at ganking, shutting down a jungling or otherwise solo farming Enigma.

* Arena Of Blood prevents Bloodseeker from attacking a Ruptured target.
* Bulwark helps Mars survive Rupture ganks simply by turning towards Bloodseeker without moving.
* Spear of Mars and God's Rebuke can push Bloodseeker from Ruptured targets.

* Long ranged disables, especially those that pierce spell immunity, cancel Black Hole: Beastmaster's Primal Roar, Bane's Fiend's Grip, Faceless Void's Chronosphere, Magnus's Reverse Polarity, Axe's Berserker's Call, Pudge'sMeat Hook.

* Heroes who have summons, which can be quickly cleared by his powerful area of effect skill: Nature's Prophet, Enigma, Lycan

* Illuminate can wipe the pushing Eidolons in a lane with ease, diminishing Enigma's laning presence by a lot.
* Solar Bind will severely slow down Enigma and make him more vulnerable to magical damage more he moves for it's duration.
* However, Keeper of the Light does not have any way to cancel Black Hole outside from Will-O-Wisp from Aghanim's Scepter.

* Enigma is fragile, and lacks escapes, being dependent on Blink Dagger for mobility. Ganking Heroes or Heroes with burst damage will likely kill him before he can do anything. Such Heroes include: Lina, Lion, Luna, Puck, Slark, Nyx Assassin, etc.

Additional:
* Enigma's uncontrollable damage from Malefice and Midnight Pulse make him easy to stun with Spiked Carapace.
* Black Hole can be easily interrupted by Impale or Spiked Carapace.

* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Frail heroes who lacks mobility: Crystal Maiden, Enigma, Dark Willow, Vengeful Spirit.

Additional:
* Riki can potentially catch an Enigma out of position and prevent him from properly blinking and initiating, thanks to Cloak and Dagger.
* Before Enigma gets his Black King Bar, Smoke Screen can be used to cancel Black Hole. After Enigma gets Black King Bar, Riki can also cancel Black Hole with Abyssal Blade, which is a common item built on him.
* Tricks of the Trade renders Riki hidden and invulnerable, which in combination with Abyssal Blade allows Riki to cancel Black Hole with little to no worries of getting caught in it.
* Enigma's fragility during all stages of the game makes him extremely prone to Riki's ganking.

* Heroes with strong channeling spells like Crystal Maiden's Freezing Field, Bane's Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.

Additional:
* Vengeful Spirit can interrupt Black Hole's channeling through Black King Bar by using Nether Swap from a safe distance.
* Vengeful Spirit's Level 25 Talent can make her Magic Missile pierce spell immunity, giving her another option to use in conjunction with Nether Swap to cancel Enigma's Black Hole channeling even through both, Black King Bar and Linken's Sphere.

* Heroes with illusion and clone abilities may confuse Bloodseeker, causing him to waste time in fights: Phantom Lancer, Chaos Knight, Arc Warden

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Enigma's Midnight Pulse damage can be substantially mitigated by Anti-Mage's high magic resistance thanks to Counterspell.
* In the early game, Anti-Mage's Mana Void can cancel a Black Hole until Enigma gets Black King Bar.
* Should Anti-Mage survive a Black Hole combo, Enigma will have exhausted most of his skills and items, preventing him from defending himself against any counter initiation or a follow-up from a blink escape.
* Anti-Mage's Blink will make him a very hard target to use Black Hole on, having to solo ult him later on in the game or leave him out of the Black Hole.

* Take Aim extends Sniper's attack range, allowing him to position himself safely behind his team, making it difficult to catch him in Enigma's relatively small area-of-effect for Black Hole. When left unattended, he can quickly kill a channeling Enigma (often from the high ground) to rout an otherwise strong initiation.
* In the early game, Sniper can cancel Enigma's Black Hole with Assassinate's ministun. Due to the absolutely ginormous 3000 cast range on Assassinate, Sniper does not need to be too close to Enigma to cancel his Black Hole. Aghanim's Scepter upgraded Assassinate can also stun Enigma for a longer duration.
* Both Shrapnel and Assassinate put Enigma's Blink Dagger on cooldown, potentially forcing him to prematurely activate Black King Bar.
Additional:
* Sniper has a very long range, so it is rare that Enigma can catch him in a Black Hole.
* Assassinate can easily cancel Black Hole if he is not caught, especially with Aghanim's Scepter.
* Enigma's Eidolons from Demonic Conversion are useless to push against a Sniper as he will easily kill them, especially with Maelstrom/Mjollnir.

* Damage reduction from Atrophy Aura prevents Bloodseeker from killing targets and gaining his Thirst bonuses.
* Pit of Malice's area of effect catches Bloodseeker easily, negating his speed bonus during teamfights.
* Dark Rift allows Underlord to transport Ruptured allies to the fountain, rendering it useless.

* 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.

* Guardian Angel's near invulnerability denies Bloodseeker the bonuses from Thirst, preventing him from gaining the upper hand in teamfights.
* Purification's pure damage makes it hard for Bloodseeker to pursue enemies, and prevents him from replenishing his health by finishing off enemies.

* Despite Clinkz's fragility, his harassment in the early game can be devastating; as he can kite Enigma and his Eidolons and claim their bounty with Burning Barrage and Searing Arrows.
* Clinkz often goes for a disabling item like Bloodthorn or Gleipnir, which allows him to cancel Enigma's Black Hole until Enigma gets Black King Bar. Gleipnir can also root Enigma, preventing him from using Blink Dagger to escape from Clinkz.
* Even with Black King Bar, Clinkz can still easily kill Enigma as all of his abilities ingore spell immunity, and Enigma is a very easy target for Burning Barrage, which means Clinkz can solo Enigma at any stage of the game unless Clinkz is caught in Black Hole.

* Heroes with illusion and clone abilities may confuse Bloodseeker, causing him to waste time in fights: Phantom Lancer, Chaos Knight, Arc Warden
