Brewmaster
* Brewmaster is slow and has low armor, making his laning stage very difficult against Geminate Attack.
* Apart from the slow moving 
Hurl Boulder, which can be disjointed, he has no control to catch Weaver.
Bristleback
* 
Shukuchi gets Weaver in front of Bristleback, negating the protection from 
Bristleback.
* Weaver's mana break talent depletes Bristleback's mana pool, preventing him from spamming abilities.
Brewmaster
* Blinking heroes like 
Anti-Mage or 
Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
Bristleback
* Mana Break quickly eats away at Bristleback's small mana pool, preventing him from spamming 
Viscous Nasal Goo and 
Quill Sprays.
* Bristleback has no innate mobility. Bristleback is easily kited by Blink, ignoring the protection from Bristleback.
Additional:
* 
Mana Break removes both a percentage and flat amount of your mana, preventing Bristleback from using abilities in the lane.
* 
Blink Anti-Mage has very high mobility with this skill, and can easily escape from Bristleback since he has no way to prevent his blink. He can also use this offensively to get in front of Bristleback during fights.
Brewmaster
* 
Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Lion has used all his crowd control before entering a fight. His direct magic burst also makes Brewmaster's Drunken Brawler worthless versus Lion.
Bristleback
* 
Lion's 
Mana Drain is a headache for Bristleback to deal with during the laning stage, as it denies him the ability to get last hits with Quill Spray.
Brewmaster
* 
Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Shaman has used all his crowd control before entering a fight.
* Brewmaster also has no defense against Shadow Shaman lockdowns.
Bristleback
* 
Duel makes Bristleback fight Legion Commander face to face, forcing him to take full damage.
* 
Press the Attack dispels the slow from stacks of Viscous Nasal Goo.
Additional:
* When dueled, Bristleback will have to face Legion head on, not allowing his passive Bristleback to come into effect.
Bristleback
* Undying's Decay is a dangerous ability against Bristleback, as it makes him more vulnerable and reduces his tankiness.
* Undying's Tombstone together with Flesh Golem can slow Bristleback down significantly.
Brewmaster
* After Brewmaster has committed Thunder Clap and Cinder Brew to gank, Bane can use 
Nightmare on Brewmaster to wait out the debuffs, and might even turn the tables by buying time for allied reinforcements.
* Bane can also prevent Brewmaster from using Primal Split with his long disables.
Bristleback
* 
Nethertoxin disables Bristleback's passive.
* 
Viper Strike and 
Poison Attack slow down Bristleback's movement speed, making him unable to get out from Nethertoxin.
Additional:
* Viper Strike can disable Bristleback and prevents 
Warpath from building stacks. Besides losing his defensive passive, Bristleback also loses his ability to build up damage over lengthy battles.
* Viper can perpetually kite Bristleback with Poison Attack and Viper Strike.
Brewmaster
* 
Ancient Seal's instant cast time will often silence Brewmaster before he can do anything.
* Brewmaster also has no defense against Skywrath Mage's massive magical damage.
Brewmaster
* 
Exorcism kills Primal Split's units very quickly.
Bristleback
* 
Eye of the Storm melts Bristleback's armor, and makes him much less tanky.
* 
Static Link can completely drain Bristleback's bonus damage from Warpath.
* 
Storm Surge allows Razor to outdistance Bristleback, even with a few stacks of Viscous Nasal Goo on him. Also, if Razor has his Shard, it will deal full damage to Bristleback every time he uses Viscous Nasal Goo (as Bristleback will face him to cast it).
Additional:
* Eye of the Storm melts Bristleback's armor, and makes him much less tanky.
* Static Link can completely drain Bristleback's bonus damage from Warpath.
Bristleback
* 
Arcane Curse stacks every time Bristleback uses an ability, forcing him to stop spamming his abilities, or take heavy health degeneration.
* 
Glaives of Wisdom steals intelligence both permanently and temporarily, causing mana issues for Bristleback.
* 
Last Word and 
Global Silence stops Bristleback from using his abilities altogether.
Additional:
* Bristleback will not be able to cast Viscous Nasal Goo or Quill Spray while silenced, effectively blocking a major part of the hero's damage and preventing Warpath charges from stacking.
* Arcane Curse slows Bristleback down and lasts longer the more abilities he uses. On the other hand, if he doesn't use any abilities, he will begin to lose Warpath charges.
Bristleback
* 
Essence Shift allows Slark to hit Bristleback freely whether on the front or back, stealing attributes and make Bristleback much less tanky.
* 
Pounce can be used to disengage and recover lost HP with his ultimate passive, and can return to fight in a short period while Bristleback is already injured and got some of his attributes stolen.
* 
Dark Pact makes it near impossible to keep the Viscous Nasal Goo debuff on Slark.
* Although Dark Pact cannot dispel Quill Spray, meaning that Slark will still receive quill stack damage even if he used 
Shadow Dance before.
* Slark builds 
Silver Edge in almost every game, an item that greatly counters Bristleback.
Bristleback
* 
Whirling Death deals damage while also reducing {Show:A|Timbersaw|Whirling Death|value4} of Bristleback's strength, making him less tanky.
* 
Reactive Armor can sustain through multiple Viscous Nasal Goo and Quill Spray stacks.
* 
Timber Chain makes it hard for Bristleback to slow down Timbersaw even with Viscous Nasal Goo.
Bristleback
* 
Guardian Sprint allows Slardar to outrun Bristleback, even when slowed by Viscous Nasal Goo.
* 
Corrosive Haze's armor reduction makes Bristleback much less tanky.
Bristleback
* 
Sharpshooter deals massive damage to Bristleback and applies a high duration disable on his passive.
* 
Bushwhack and 
Scurry can be used to easily kite Bristleback.
Additional:
* Bristleback and Warpath can be disabled by Hoodwink's Sharpshooter ability for a long period of time, reducing his both offense and defense.
* Scurry and Bushwhack can be used to kite bristleback.
Bristleback
* 
Phantom's Embrace silences Viscous Nasal Goo and Quill Spray.
* 
Ink Swell stuns Bristleback and gets allies in position faster with increased movement speed to attack his front, countering his passive ability.
Bristleback
* 
Infernal Blade deals scaling damage and is useful against high health targets such as Bristleback.
* 
Doom disables Bristleback's low cooldown abilities, preventing him from triggering Warpath. With his upgraded level 25 talent, it also breaks Bristleback's passive, rendering him more vulnerable.
Additional:
* Infernal Blade deals scaling damage and is useful against high HP targets such as Bristleback.
* Doom prevents Bristleback from casting his two low cooldown abilities, which then prevents him from utilizing Warpath.
* If Doom chooses the Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, he can disable Bristleback and Warpath, taking away much of his durability and damage potential in team fights.
Bristleback
* 
Shadow Demon's 
Demonic Purge with 
Aghanim's Scepter disables Bristleback's passives.
Bristleback
* Heroes with high health especially Strength heroes will take more damage on Sun Ray: 
Axe, 
Pudge, 
Bristleback, 
Mars.
Brewmaster
* Blinking heroes like Anti-Mage or Queen of Pain can often chase down an injured Brewmaster after his ultimate expires.
Bristleback
* 
Terrorblade's 
Sunder is not affected by the Bristleback damage reduction.
Bristleback
* 
Batrider's turn rate slow from 
Sticky Napalm makes it harder for Bristleback to keep his back towards the enemy.
Bristleback
* 
Reaper's Scythe and 
Heartstopper Aura deal percentage-based damage, ignoring Bristleback's high health.
* Heartstopper Aura's HP removal does not trigger Bristleback's passive.
Additional:
* Heartstopper Aura deals percentage-based damage flagged as HP removal, so it is not reduced by Bristleback, nor does it trigger passive Quill Sprays.
* Reaper's Scythe is very effective against Bristleback not only due to its percentage-based damage, but rather because it first stuns and then deals its damage, allowing Necrophos to position in front of Bristleback in time.
Bristleback
* Enemies that possess high defenses through magic resistance, damage reduction, or high regeneration will make it difficult to whittle their health down to get to Reaper's Scythe's threshold. Such heroes include Bristleback (although only from behind), 
Spectre, 
Ursa, and 
Dragon Knight.
Bristleback
* 
Time Dilation prevents Bristleback from spamming his low-cooldown abilities, greatly reducing his damage and effectiveness.
* 
Chronosphere allows allies to reposition and hit Bristleback from the front, bypassing his defensive bonus from behind.
* Bristleback has no way to prevent Void from using 
Time Walk.
Additional:
* Time Dilation while Quill Spray and Viscous Nasal Goo are on cooldown will make these abilities unusable for a long time, rendering Bristleback nearly useless.
* Bristleback cannot turn inside the Chronosphere, which makes it easy to attack him from the front, completely bypassing his passive damage reduction.
Brewmaster
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: Ursa, 
Clinkz, 
Faceless Void, 
Troll Warlord, 
Templar Assassin, 
Phantom Assassin.
Additional:
* 
Thunder Clap and 
Drunken Brawler prevent Faceless Void from maximising his damage potential in fights.
* 
Cyclone disables Faceless Void during Chronosphere or in general.
Brewmaster
* 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 Phantasms early on, and can still deal a lot of damage to them late game, revealing the real Chaos Knight.
Bristleback
* Quill Spray quickly destroys Chaos Knight's 
Phantasms.
Brewmaster
* 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.
Bristleback
* 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.
Brewmaster
* Brewmaster can use Cyclone to disable Huskar's healer for much longer than most other heroes can, to make Huskar vulnerable.
* Huskar has no way to stop Brewmaster from using Primal Split by himself, but can cut a good amount of his high health away if Huskar's team wants to burst Brewmaster down during a different disable.
Bristleback
* The damage from 
Burning Spear can be reduced by turning away from Huskar.
* Bristleback can bait Huskar into using 
Life Break on him, then turn around and receive very little damage.
Additional:
* Bristleback's tankiness and Bristleback allow him to outlast Burning Spears' damage-over-time at almost any point in the game. In addition, if Huskar chooses to cast Life Break on Bristleback, Bristleback can simply turn around before it hits and receive little damage.
* Viscous Nasal Goo will reduce Huskar's low armor even further, and Quill Spray and Warpath will tear him down extremely quickly.
Brewmaster
* Brewmaster can make the Spirit Bear a much smaller threat with Cinder Brew.
* Cyclone removes the bear from a fight so that his team can easily focus on the hero.
* While most heroes would be worn down by a Spirit Bear 
Radiance in the time it takes to kill Lone Druid, Brewmaster is protected in Primal Split.
Bristleback
* Lone Druid and The Spirit Bear cannot burst down Bristleback due to Bristleback
* Bristleback can easily run to Lone Druid without any hesitation, with Viscous Nasal Goo to reduce armor and slow the Spirit Bear or Lone Druid and Quill Spray can deal damage to both Lone Druid and the Spirit Bear at the same time
Brewmaster
* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: 
Broodmother, 
Enigma, 
Nature's Prophet.
Bristleback
* 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.
Brewmaster
* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: Broodmother, Enigma, Nature's Prophet.
Bristleback
* Quill Spray destroys spiderlings, and hits Broodmother even when she's regenerating in her webs. This makes Bristleback one of her hardest counters in lane.
Additional:
* Bristleback reduces most of Broodmother's and her spiderlings' damage.
* Quill Spray will hit any spiders in its proximity, hindering Broodmother's fighting and farming capabilities.
Brewmaster
* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: Broodmother, Enigma, Nature's Prophet.
Bristleback
* Heroes that have AoE damage: 
Lina, 
Keeper of the Light, 
Timbersaw, 
Leshrac, Bristleback, Axe.
Bristleback
* Bristleback's tankiness and damage reduction from the rear makes him very hard for Phantom Lancer to chase and finish off, due to his lack of burst damage.
* Quill Spray quickly destroys Phantom Lancer's illusions.
* Bristleback's passive costs no mana, meaning that it will continue to trigger even if Phantom Lancer drains Bristleback's mana with 
Diffusal Blade.
Additional:
* Bristleback's tankiness and damage reduction from the rear makes him very hard for Phantom Lancer to chase and finish off, due to his lack of burst damage.
* Quill Spray destroys Phantom Lancer's illusions.
* Bristleback's passive costs no mana, meaning that it will continue to trigger even if Phantom Lancer drains Bristleback's mana with Diffusal Blade.
Brewmaster
* 
Cinder Brew and Drunken Brawler makes it hard for Monkey King to stack Jingu Mastery.
* Cyclone can remove Monkey king for 6 seconds if his allies lack dispels.
* Dispel Magic can dispel Jingu Mastery's bonuses.
Brewmaster
* The three Primal Split brewlings all attacking Templar Assassin at once will remove her 
Refraction quickly, especially with Fire's Permanent Immolation.
* Templar Assassin has no way to stop Brewmaster from using Primal Split by herself, and may get unlucky and miss her 
Meld if trying to burst him during her ally's disable.
Bristleback
* Viscous Nasal Goo slows down Dragon Knight and lowers armor, locking him down and making him more vulnerable.
Bristleback
* Tiny's nonexistent armor in the early game makes him very vulnerable to Quill Spray's large amounts of physical damage.
* Bristleback decreases Tiny's high burst damage against Bristleback.
* Viscous Nasal Goo can slow Tiny to a crawl and allows Bristleback to easily kite him with his high movement speed and Quill Spray's long range, as Tiny has no ability to escape.
Bristleback
* Viscous Nasal Goo can hinder Crystal Maiden's already abysmal mobility, which allows Bristleback (or his teammates) to run her down and kill her.
* Bristleback frequently builds 
Blade Mail, which can quickly kill Crystal Maiden if her ultimate is used while he is under its effect.
* The passive part of Bristleback will trigger many, many times under the damage from Freezing Field, and as the stacks increase, the damage output from each successive cast (or proc) will eat away at Crystal Maiden's small HP pool.
Bristleback
* 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.
Additional:
* Pudge is particularly susceptible to Bristleback's Viscous Nasal Goo and Quill Spray due to his naturally low armor and 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.
Bristleback
* Quill Spray will hit Riki even when he is invisible.
* 
Cloak and Dagger's bonus backstab damage is rendered irrelevant against Bristleback.
* 
Smoke Screen does not stop Bristleback's passive from activating.
* Due to Bristleback's natural tankiness, he is an ideal 
Gem of True Sight carrier, directly countering Riki's invisibility.
Additional:
* The bonus Backstab damage from Cloak and Dagger is rendered irrelevant with Bristleback and hurts Riki more than him because of the passive Quill Spray.
* Riki can still get damaged by Bristleback's Quill Spray while invisible, and it can be hard to deal with in lane.
* Bristleback is not too bothered by Smoke Screen. Though he cannot use Quill Spray manually inside it, it still procs passively when he takes damage from the back. The movement speed from Warpath allows him to get out of the area easily.
* Due to Bristleback's natural tankiness, he is an ideal Gem of True Sight carrier.
* Riki rarely buys Silver Edge to break Bristleback's passive because the invisibility aspect of it is redundant.
Brewmaster
* Cyclone from Storm in 
Primal Split can waste Nyx's Spiked Carapace, since its duration is shorter than the Cyclone's.
Bristleback
* Quill Spray's constant AoE damage will hit Dark Willow even in Shadow Realm. Its automatic damage will hurt her if she tries to get close and use Bedlam.
Bristleback
* Quill Spray is very effective against Io, as it has very low armor and has to stay close to the fight to not break its Tether.
Bristleback
* Combo Quill Spray and items Blade Mail can easily trigger from Focus Fire damage.
Additional:
* Using Focus Fire on Bristleback tends to fare badly for Windranger, as he can trigger passive Quill Sprays many times, especially when she attacks him from behind. In addition, Windrun does not protect her from both Viscous Nasal Goo and Quill Spray, rendering her helpless.
* Bristleback's natural tankiness makes it hard for Windranger to effectively burst her down throughout the game.
* Bristleback tends to continuously spam Viscous Nasal Goo to slow down Windranger when she uses Windrun to escape, potentially allowing him to outrun her with his Warpath stacks.
* Bristleback can build 
Lotus Orb to reflect Shackleshot and Focus Fire back at Windranger.
Bristleback
* Quill Spray usually hits Meepo's clones, although Bristleback cannot turn his back when rooted with 
Earthbind.
Bristleback
* Quill Spray will hit Sand King inside 
Sand Storm, damaging him and putting Sand King's 
Blink Dagger on cooldown, preventing him from escaping.
* 
Epicenter's numerous damage ticks will trigger Bristleback's passive repeatedly during teamfights.
Brewmaster
* {U:Earth} has passive 
Spell Immunity, allowing him to walk into the Echo Stomp radius to stun Elder Titan with his Hurl Boulder.
* {U:Storm}'s Cyclone can cancel the channeling of Echo Stomp and take Elder Titan out of the fight for {show:A|Storm|Cyclone|value2} seconds.
Brewmaster
* If Ursa uses 
Enrage Brewmaster can use Cyclone to render him harmless during his ultimate.
* Brewmaster has two spells to slow down Ursa, allowing his team to kite around him easily.
Bristleback
* Arc Warden has relatively lower armor and mobility, which makes him an easy target to apply Quill Spray and Viscous Nasal Goo stacks.
* Arc Warden also does not like to build a Silver Edge as it takes a long time to build up and may slow down the timings for other important items needed in the game like 
Gleipnir.
* However, do note that in a game where Arc Warden's team has many jumping capabilities or good passives, like a 
Tidehunter or Spectre, a Silver Edge becomes incredibly valuable on Arc Warden as not only can he run away from the jumps, he effectively gets 2 breaks, and Bristleback may not be the best pick.
Bristleback
* Fortune's End cannot dispel Warpath stacks on Bristleback or Quill Spray stacks on allies.
* Bristleback can heavily reduce Oracle's damage output. With it, Oracle may accidentally heal Bristleback with Purifying Flames, especially if Bristleback has bonus magic resistance.
Brewmaster
* Dispel Magic from {U:Storm} instantly removes Heavenly Grace and Guardian Angel from Omniknight's allies in its radius of effect.
Brewmaster
* {U:Storm} can use Cyclone on Abaddon when he activates Borrowed Time, wasting its duration.
* Drunken Brawler and Thunder Clap hinder Abaddon from applying Curse of Avernus' silence on him.
Additional:
* Dispel Magic can remove Abaddon's 
Aphotic Shield or 
Curse of Avernus on an allied hero.
* Cyclone's lengthy duration wastes much of 
Borrowed Time's duration.
Bristleback
* Heroes with damage-over-time abilities easily allow Bristleback to turn his back in order to proc Bristleback continuously and to massively reduce to damage dealt to him: 
Arc Warden, 
Venomancer, 
Luna.
Bristleback
* Axe, Bristleback, 
Centaur Warrunner, 
Spirit Breaker, Pudge, 
Huskar, 
Wraith King, 
Doom: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
Bristleback
* Heroes with damage-over-time abilities easily allow Bristleback to turn his back in order to proc Bristleback continuously and to massively reduce to damage dealt to him: Arc Warden, Venomancer, Luna.
Additional:
* Quill Spray and Bristleback harass Luna more efficiently than she does with Lucent Beam.
* Bristleback helps return a lot of damage to Luna’s team if she uses her nukes on him and he has his back to her.
* Viscous Nasal Goo and Warpath are enough to outrun a speedy Luna.
* Bristleback tends to be a frequent carrier of 
Crimson Guard and 
Eternal Shroud, which are good protection from 
Moon Glaives and 
Eclipse.
* For the same reasons, Bristleback makes a very powerful ally for Luna when they are in the same team.
Brewmaster
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: Ursa, Clinkz, Faceless Void, Troll Warlord, Templar Assassin, Phantom Assassin.
Brewmaster
* 
Brewmaster with Primal Split
* Heroes that can dodge Glimpse:
* 
Puck with 
Phase Shift
* 
Riki with 
Tricks of the Trade
* 
Phantom Lancer with 
Doppelganger
* 
Ember Spirit with 
Sleight of Fist and 
Activate Fire Remnant
* 
Chaos Knight with Phantasm
* 
Naga Siren with 
Mirror Image
* 
Tusk with 
Snowball
* 
Juggernaut with 
Omnislash
* Brewmaster with Primal Split
* 
Lifestealer with 
Infest
* 
Phoenix with 
Supernova
Brewmaster
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: Ursa, Clinkz, Faceless Void, Troll Warlord, Templar Assassin, Phantom Assassin.
Brewmaster
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: Ursa, Clinkz, Faceless Void, Troll Warlord, Templar Assassin, Phantom Assassin.
Bristleback
* Bristleback's Viscous Nasal Goo can catch and slow Bounty Hunter. Warpath and Quill Spray can defeat him quickly due to his small HP pool when compared to Bristleback's.
Bristleback
* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback, Clinkz, Luna,
Shadow Fiend, 
Slardar, Terrorblade
Brewmaster
* Heroes with area dispel can kill multiple skeletons at once: Brewmaster, 
Oracle.
Bristleback
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter, Bristleback, Slardar.
Brewmaster
* Heroes with strong team-fight abilities (especially ultimates) like Tidehunter, Brewmaster, 
Death Prophet, etc.
Bristleback
* Bristleback's abilities are nearly useless for Rubick to 
Spell Steal, as he does not gain the bonuses from Warpath.
Additional:
* Rubick deals little damage on his own, and Bristleback can simply shrug off all his spells and chase Rubick down with his Quill Spray and the damage bonus from Warpath.
* Rubick does not tend to charge forward in teamfights, stay in the front lines under most circumstances, yet effective casts of Quill Spray and Viscous Nasal Goo requires the opposite as they require multiple casts and close range to add up stacks.
* Rubick does not benefit from Warpath through casting the stolen spell.
Bristleback
* Heroes that withstand damage like Timbersaw, Bristleback, Dragon Knight and others will have their durability largely reduced when hit by an Ice Blast due to the risk of shattering.
Brewmaster
* Primal Split makes Brewmaster invulnerable for the duration, rendering effects of Cold Feet and Ice Blast useless.
* Dispel Magic can dispel Cold Feet from allies.
* Brewmaster can easily run Ancient Apparition down with the slow from Thunder Clap and Cinder Brew.
Bristleback
* While Jakiro's damage is going to be little more then average against him due to his Bristleback. His large quantity of stuns can prevent Bristleback from getting his much needed Warpath stacks, while also giving his allies a chance to counter his high defense.
* Dual Breath and Liquid Frost both reduce Movement Speed, removing one of Bristlebacks greatest strengths.
* Liquid Fire reduces Bristlebacks Attack Speed, making it harder for him to burst down a hero with Warpath.
* However Bristleback can generally catch and kill a lone Jakiro. And Jakiro is only effective in a group.
Bristleback
* 
Macropyre's frequent damage ticks causes Bristleback to activate repeatedly, resulting in free damage as long as Bristleback faces away from Jakiro.
Bristleback
* Spirit Breaker's 
Nether Strike with 
Aghanim's Shard disables Bristleback's passives.
Bristleback
* Heroes who can continue dealing damage even while being stunned: Luna, 
Razor, Axe, Bristleback, Leshrac, Death Prophet, 
Jakiro.
Bristleback
* Axe forces Bristleback to turn around with 
Berserker's Call, allowing allies to attack him without fear of his passive.
Bristleback
* Heroes who can stop Axe from getting close will severely inhibit his presence in fights: Bristleback, 
Crystal Maiden, Batrider, Arc Warden, 
Winter Wyvern, 
Clockwerk
Brewmaster
* Outworld Destroyer's pure damage will mop up Primal Split's units very quickly.
Bristleback
* Outworld Destroyer's high burst damage is not negated by Bristleback's passive. So, even if Bristleback turns his back on Outworld, he can decimate Bristleback quickly.
Astral Imprisonment, both reducing Bristlebacks much needed mana and allowing Outworld to move in front of him, forcing him to take the full damage from his spells. This will also allow Outworld to land a devasting Sanity's Eclipse, without it being reduced by Bristleback's passive.
* If Bristleback attempts to flee, or tries to close the gap, Outworld can banish him with
