* Spiked Carapace stops Snapfire's Mortimer Kisses.

* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.

* Silence can be used to interrupt Primal Beast while he is channeling Pulverize.
* Spirit Siphon can whittle down Primal Beast's health and can potentially heal back any burst damage he deals to her.
* Exorcism can shed Primal Beast's health down while he attempts to complete any skill combos during a fight with it active.

* Mana Break reduces Snapfire's already low mana pool.
* Blink allows Anti-Mage to avoid being hit by Lil' Shredder and Mortimer Kisses.

* Oracle can negate and shut down Primal Beast simply with Fate's Edict, especially in the early game, as a majority of his damage-dealing spells are magic.
* Oracle can interrupt Primal Beast's Onslaught charge with a well-timed Fortune's End.
* Primal Beast's lethal burst damage combos can be further stalled with False Promise; combined with Fate's Edict and regen from Purifying Flames, Oracle can even completely negate Primal Beast's offense.
Additional:
* Fate's Edict completely negates all of Primal Beast's major damage-dealing spells in the early game and can render Primal Beast useless when cast on a target he is focusing, or in Oracle's defense against Primal Beast himself.
* Fortune's End keeps Primal Beast in place, especially while trampling or in the middle of an Onslaught charge.
* False Promise can interrupt Primal Beast's Pulverize, as well as further delay Primal Beast from dealing lethal burst damage. In combination with Fortune's End, Oracle can potentially save an ally from Primal Beast's spell combos.

* Duel prevents Primal Beast from using all of his spells and stops all of his damage output.
* Moment of Courage will not proc if Primal Beast is using Trample so you may want to play around that if you're looking for duel damage with a Blade Mail.
* Press the Attack can be used to dispel Pulverize immediately and make allies survive Trample for a short duration with the heal.

* Aphotic Shield prevents damage and dispels the slow from Snapfire's Mortimer Kisses.
* Borrowed Time allows Abaddon to gain HP during Snapfire's Mortimer Kisses.

* Shukuchi allows Weaver to have faster move-speed and can outrun Primal Beast in most instances, such as while he is trampling.
* Trample disarms Primal Beast, so casting The Swarm can make him vulnerable to ranged attacks. Primal Beast also has an innately slow attack speed and will take long destroying the latched parasite.

* The ensare from melee Berserker's Rage can prevent Primal Beast from dealing further Trample damage and can allow Troll Warlord to relentlessly build Fervor on him.

* Whirling Axes (Melee) can blind Primal Beast if he attempts to auto-attack Troll Warlord after a fully charged Uproar.
* Battle Trance will make Primal Beast a sitting duck should he be rooted and attacked to death. It might be wise to save Pulverize for after this spell is used so you have a defensive measure against Troll Warlord.

* Malefice will prevent Primal Beast from doing anything for a long duration even in the early game when at his strongest.
* Midnight Pulse will scale with his max health so will do a ton of damage combined with any generic stun or Enigma's own abilities.
* Primal Beast relies completely on mobility to do damage, Black Hole makes sure he cannot use any abilities or threaten heroes he is typically good against.

* Diabolic Edict makes Leshrac very effective at threatening early towers and objectives which can directly cause unfavourable conflicts with Primal Beast early before he has Black King Bar to deal with the magical damage.
* Pulse Nova and the rest of Leshrac's spells can overwhelm Primal Beast with magical damage.
* Leshrac has generally faster movement speed than Primal Beast, especially if he has items such as Boots of Travel and Eul's Scepter of Divinity.
* Bloodstone also makes him heal much more than Primal Beast can damage him at any stage of the game.

* Rolling Boulder and Geomagnetic Grip allows Earth Spirit to easily stun, silence and interrupt Primal Beast in fights. Rolling Boulder can also be used to escape Primal Beast.

* Meat Hook can be used immediately after Mortimer Kisses since Snapfire is forced to stay in place.

* Primal Beast's abilities require movement to deal damage, making Rupture potentially deadly and debilitating. Furthermore, its initial damage based on the target's current health is devastating to a full-health Primal Beast with his high strength gain and thus high HP.
* Due to his reliance on spells, Primal Beast is vulnerable to Blood Rite's powerful silence without items to counter it. While silenced, Primal Beast cannot retaliate effectively with his spells.

* Glimpse can prevent Onslaught in the laning stage very easily.
* While Static Storm is not much of a threat in terms of damage, it does prevent Primal Beast from casting any spells for a long period of time if also trapped in Kinetic Field.
* Overall, Disruptor forces Primal Beast to buy a Black King Bar much earlier than he might like but becomes a major threat to Disruptor once he does.

* Invoker's numerous area-of-effect abilities can interrupt Primal Beast, especially while he is in the middle of a team fight, where Primal Beast thrives. (Tornado, Cold Snap, and Ice Wall all help to disable Primal Beast and control him from a distance.
* EMP disintegrates Primal Beast's low mana pool.
* However, Invoker is quite a slow paced hero and not particularly known for being survivable against a rampaging Primal Beast with Black King Bar.

* Storm Hammer is a good stun used in response to Primal Beast's initiation.
* Warcry can be used to outrun Primal Beast, or in response to his Uproar damage boost.
* God's Strength will make sure work of Primal Beast if caught alone due to it's increased damage.

* Phantom's Embrace is very threatening due to Primal Beast being quite spell reliant, and not being able to attack during Trample and can immediately cancel Pulverize.
* Soulbind can prevent movement in a way that's very hampering for Primal Beast's Trample and Onslaught. It can also cancel Onslaught very abruptly.
* Ink Swell can stun Primal Beast and give the holder a strong dispel with the shard. The stun can easily stop Trample damage or Pulverize from continuing even if it's not Primal Beast's main target.

* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during Mortimer Kisses and dodge the projectiles easily due to their slow speed.
* Heroes with mobility spells (such as Queen of Pain's Blink and Clockwerk with Hookshot) can easily avoid Lil' Shredder and Mortimer Kisses.
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during Mortimer Kisses and dodge the projectiles easily due to their slow speed.

* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as Troll Warlord, Lone Druid and Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.

* Primal Beast really suffers against supports he cannot bully in the lane; this includes Dazzle, Shadow Demon and Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.

* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during Mortimer Kisses and dodge the projectiles easily due to their slow speed.

* Power Cogs keeps Primal Beast pinned down, preventing him from doing damage with Trample. Primal Beast's slow attack speed makes it hard for him to break the cogs and get away. In addition, Power Cogs' knockback is forced movement, and thus will intercept Primal Beast's Onslaught if placed well.
* Battery Assault on a lone Primal Beast in the early game effectively keeps him from winding up Onslaught or basic attacking.
* Rocket Flare and Jetpack (from purchasing Aghanim's Shard) give Clockwerk many options to scout for Primal Beast, whose kit benefits greatly from ambushing.
