Dragon Knight
* In the early game, a Dragon Knight without 
Black King Bar is basically defenseless against Viper.
* Viper can harass Dragon Knight at any time with his 
Poison Attack.
* 
Corrosive Skin reduces damage from Dragon Fire and inflicts damage to him.
* 
Nethertoxin disables Dragon Blood, negating his main survivability.
* 
Viper Strike and Poison Attack can severely slow him down even with his Elder Dragon Form.
Additional:
* Dragon Knight is easily harassed by Poison Attack after the laning stage ends.
* Corrosive Skin protects Viper from 
Breathe Fire and returns damage.
* Nethertoxin mitigates 
Dragon Blood, Dragon's Knight main source of armor and health regeneration.
* Between Poison Attack and Viper Strike, Viper can keep Dragon Knight permanently slowed even in 
Elder Dragon Form.
Bounty Hunter
* Viper's poison abilities can slow Bounty Hunter's movement speed and allows to chase him with True Sight items.
* Nethertoxin can break Jinada, and the silence from level 25 prevents Bounty Hunter from using all of his spells.
Dragon Knight
* 
Slardar can chase Dragon Knight down with 
Guardian Sprint and stun him with both 
Slithereen Crush and his passive 
Bash of the Deep. He can also use 
Corrosive Haze to whittle Dragon Knight's armor.
Bounty Hunter
* Corrosive Haze provides True Sight on its target, exposing Bounty Hunter's position regardless of Shadow Walk.
* Guardian Sprint gives a very high movement speed bonus, allowing him to chase Bounty Hunter even if Slardar is tracked.
Additional:
* Bounty Hunter's 
Shadow Walk is rendered useless with Corrosive Haze and makes Bounty Hunter an easy target for Slardar and his team.
Dragon Knight
* In general, heroes that can slow down Dragon Knight's movement speed will do well against him. This includes 
Venomancer and others in addition to the heroes mentioned above.
Bounty Hunter
* Venomancer's magical damage-over-time poisons greatly reduce Bounty Hunter's mobility.
* 
Venomous Gale, combined with 
Plague Wards and 
Poison Nova with True Sight items can allow Venomancer and his teammates to gank Bounty Hunter while he is roaming alone.
Dragon Knight
* 
Viscous Nasal Goo slows down Dragon Knight and lowers armor, locking him down and making him more vulnerable.
Bounty Hunter
* 
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.
Dragon Knight
* Because Exorcism's damage is not reduce by damage block abilities or items, Death Prophet can be very good against heroes who rely on armor to survive: 
Axe, 
Terrorblade, 
Morphling, 
Dragon Knight
Bounty Hunter
* Death Prophet's 
Silence allows her to prevent Bounty Hunter from escaping with Shadow Walk.
* If Bounty Hunter cannot escape with Shadow Walk while affected by Silence, she will be able to burst him down with 
Crypt Swarm and 
Spirit Siphon.
Additional:
* Death Prophet's Silence allows her to prevent Bounty Hunter from escaping with Shadow Walk.
* If Bounty Hunter cannot escape with Shadow Walk while affected by Silence, she will be able to burst him down with Crypt Swarm and Spirit Siphon.
Dragon Knight
* 
Huskar can burn down Dragon Knight's health quickly during the early to mid game, but is not as effective during the late game. However, 
Life Break remains a constant threat due to the slow and percentage-based damage.
Additional:
* Huskar can negate Dragon Knight's passive with multiple trades of Burning Spear.
Bounty Hunter
* Huskar with Life Break
* Heroes that can remove the Track debuff with their skills:
* 
Abaddon with 
Aphotic Shield and 
Borrowed Time
* Huskar with Life Break
* 
Juggernaut with 
Blade Fury
* 
Legion Commander with 
Press the Attack
* 
Lifestealer with 
Rage and 
Infest
* 
Naga Siren with 
Mirror Image
* 
Omniknight with 
Heavenly Grace
* 
Oracle with 
Fortune's End and 
False Promise
* 
Phantom Lancer with 
Doppelganger
* 
Slark with 
Dark Pact
* 
Ursa with 
Enrage
* 
Weaver with 
Time Lapse
* 
Tidehunter with 
Kraken Shell when damage received reaches the threshold.
Dragon Knight
* Heroes who rely strongly on melee physical damage will fare badly against Omniknight's Guardian Angel: 
Phantom Assassin, Juggernaut, Dragon Knight, 
Lycan, Ursa, 
Troll Warlord
Bounty Hunter
* Omniknight with Heavenly Grace
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Dragon Knight
* In general, heroes with long cooldowns on their abilities or ultimate will struggle against the relentless pressure provided by Dark Rift or 
Fiend's Gate (Requires 
Aghanim's Scepter): Terrorblade, Dragon Knight, Omniknight.
Bounty Hunter
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map: Phantom Assassin, Terrorblade, Troll Warlord, 
Drow Ranger, Phantom Lancer, 
Chaos Knight, 
Sven, 
Wraith King, 
Bounty Hunter, 
Alchemist, 
Templar Assassin, 
Nyx Assassin, 
Bane.
Bounty Hunter
* Spectre can instantly reveal Bounty Hunter's position on the activation of her ultimate 
Haunt. She can also semi-reveal( visible but not target-able) Bounty Hunter by hitting him with 
Spectral Dagger.
Bounty Hunter
* 
Lightning Bolt makes roaming behind enemy lines more and more difficult as Zeus becomes powerful enough to spam it. Also, Zeus' Ultimate 
Thundergod's Wrath reveals Bounty Hunter regardless of his position.
Additional:
* Bounty Hunter has a very low health pool, allowing Zeus to burst him down quickly.
* Zeus can cast Lightning Bolt to gain True Sight in any area he suspects Bounty Hunter may be invisible or any area he thinks Bounty Hunter may have warded.
* If Bounty Hunter tries to escape a gank by using Shadow Walk, Zeus can gain vision of him with both Lightning Bolt and Thundergod's Wrath.
Dragon Knight
* 
Arcane Orb's constant pure damage output is devastating to Dragon Knight.
* Dragon Knight's relatively low mana pool leads to heavy damage from 
Sanity's Eclipse, which also bypasses his armor.
Dragon Knight
* Lich's constant slows with 
Frost Blast and 
Chain Frost will slow Dragon Knight to a crawl, especially in a crowded teamfight.
Bounty Hunter
* Even though Luna is the kind of hero that Bounty Hunter can handle due to Shadow Walk rendering him safe from 
Eclipse, smart Luna will always buy 
Dust of Appearance, allowing her to provide vision on him to her team, and possibly, kill Bounty Hunter with Eclipse.
Dragon Knight
* 
Fury swipes can tear Dragon knight down as it stacks infinitely.
Bounty Hunter
* Ursa with Enrage
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Bounty Hunter
* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: 
Crystal Maiden, 
Sniper, Ursa, 
Witch Doctor, etc.
Dragon Knight
* 
Static Link saps Dragon Knight of his already low base damage, making him even more useless in a fight if he gets kited.
* 
Storm Surge makes Razor much faster than Dragon Knight, and hard to catch.
* 
Eye of the Storm melts Dragon Knight's armor and bypasses Black King Bar, his core item.
Bounty Hunter
* Rubick is a potential counter to Bounty Hunter as he can steal his Track and use it against his invisibility, and also provide his team with more gold if the tracked hero is killed.
Dragon Knight
* Timbersaw's pure damage will kill Dragon Knight surprisingly fast, especially if he gets caught in a bad position while laning.
* Items 
Lotus Orb for Timbersaw make Dragon Tail affected stunned back to Dragon Knight's although Timbersaw stricken by Dragon Tail.
Bounty Hunter
* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and Wraith King to heroes with quick escape mechanisms like 
Anti-Mage and 
Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.
Bounty Hunter
* Oracle with Fortune's End and False Promise
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break

* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Dragon Knight
* 
Elder Titan's 
Natural Order completely nullifies Dragon Knight's high armor.
Dragon Knight
* Heroes with no mobility will take some good damage from Sand King's spells: Dragon Knight, 
Jakiro, 
Pugna, 
Earthshaker.
Bounty Hunter
* Heroes who rely on invisibility, such as Bounty Hunter, 
Clinkz, 
Mirana, Nyx Assassin and 
Riki, as they will be revealed if caught by Chronosphere.
Dragon Knight
* Heroes that relies on armor or other type of physical damage negation are easy for Gyrocopter to take down during the early game with his magical damage: Axe, Dragon Knight, Sven.
Bounty Hunter
* Slark with Dark Pact
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break

* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Dragon Knight
* Durable heroes relied a lot on their main passive effects and items' effects such as Bristleback, 
Underlord, 
Spectre and Dragon Knight can be disabled easily with 
Sharpshooter's break, reducing their potential in teamfights.
Dragon Knight
* Heroes that lose a great amount of their tankiness and become easier to finish off: Bristleback, Spectre, Phantom Assassin, 
Enchantress, Dragon Knight.
* Once you have an Aghanim's Scepter, Shadow Demon instantly reaches a new power spike and becomes a counter for a variety of heroes that have strong passives.
* Heroes that lose a great amount of their tankiness and become easier to finish off: Bristleback, Spectre, Phantom Assassin, Enchantress, Dragon Knight.
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.
* You can always stack camps and farm the scepter with Shadow Poison.
Bounty Hunter
* Tidehunter with Kraken Shell when damage received reaches the threshold.
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image

* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Bounty Hunter
* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and Wraith King to heroes with quick escape mechanisms like Anti-Mage and Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.
Bounty Hunter
* 
Finger of Death can instantly shred many targets, especially fragile Heroes like 
Keeper of the Light, 
Ancient Apparition or Bounty Hunter.
Bounty Hunter
* Techies is very good against roaming supports and gankers such as Bounty Hunter, Riki, Weaver, Earthshaker, Nyx Assassin, etc. that are constantly moving around the map.
Dragon Knight
* Heroes who rely on burst physical damage are affected by Lucky Shot's disarm: Terrorblade, Sven, Clinkz, 
Windranger, Alchemist, Dragon Knight, Legion Commander
Bounty Hunter
* Heroes who rely on their target to run away: Riki, Bounty Hunter.
Dragon Knight
* 
Heartstopper Aura and 
Reaper's Scythe go right through Dragon Knight's armor.
Dragon Knight
* 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.
Dragon Knight
* Dragon Knight has no built-in disengage from 
Frost Arrows, and 
Marksmanship procs ignore base armor, bypassing Dragon Knight’s durability for the most part, making Drow one of the few heroes that can deal enough sustained damage to solo kill Dragon Knight.
* With Aghanim's Scepter, Frost Arrows also apply hypothermia stacks, reducing her target’s regen, which is especially potent against tanks like Dragon Knight. (A similar effect can also be achieved with an 
Eye of Skadi).
Bounty Hunter
* Invisible heroes are very difficult for Drow Ranger to deal with such as Bounty Hunter, Riki and heroes who commonly buy a 
Shadow Blade.
Dragon Knight
* Dragon Knight's heavy armor negates 
Vendetta's burst physical damage. His large HP pool also gives him a good chance of surviving Nyx Assassin's follow-up nuke damage.
Bounty Hunter
* Nyx Assassin wants to start ganking as soon as he gets his Vendetta. Keeping him Tracked prevents him from ganking, and thus from doing his job in the game.
* Nyx Assassin has a lot of armor and health regen, making the nuke damage from Shuriken Toss very good against him.
Additional:
* 
Track hinders Nyx Assassin's ganking attempts with Vendetta, making him an easy kill for gold as well.
Dragon Knight
* Despite the armor reduction from 
Meld, Templar Assassin's reliance on physical damage and medium attack speed is unlikely to harm Dragon Knight.
* Templar Assassin's Refraction charges also get quickly removed by the damage over time from Dragon Knight's ultimate.
Additional:
* The damage over time from Dragon Knight's Elder Dragon Form rapidly burns down Refraction, allowing him to attack her.
* Also, Breathe Fire reduces Templar Assassin's damage and 
Dragon Tail is a stun with a considerable duration, letting him and his team whittle her health down once her defenses wear off.
* Templar Assassin will struggle to kill Dragon Knight thanks to his high armor and health regen from Dragon Blood as she deals entirely physical damage.
Bounty Hunter
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: 
Earth Spirit, 
Spirit Breaker, 
Tusk, Bounty Hunter, Riki, 
Warlock.
Dragon Knight
* Heroes who can match Void Spirit's mobility (like the aforementioned 
Ember Spirit or 
Queen of Pain) or tank his spells (Dragon Knight or 
Centaur Warrunner) are very problematic for him.
Bounty Hunter
* One hit with 
Jinada should be sufficient in removing Void Spirit's shield most of the time.
* Track negates much of Void Spirit's escape abilities by revealing his position and prevents him from rotating effectively.
Dragon Knight
* Riki does little damage to Dragon Knight, as he relies only on physical damage with modest attack speed and lack of burst.
Bounty Hunter
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:Clinkz, Riki, 
Treant Protector, etc.
Additional:
* Track reveals Riki while invisible and gives him a hard time, as it prevents much of his ganking capabilities. This can force Riki to buy 
Manta Style to dispel it.
Dragon Knight
* Dragon Knight can simply tank and destroy all Shadow Shaman's Serpent Wards.
Bounty Hunter
* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
Dragon Knight
* 
Death Ward does little damage against Dragon Knight's armor, and Dragon Knight's high health regeneration minimizes damage from 
Maledict.
Bounty Hunter
* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, Sniper, Ursa, Witch Doctor, etc.
Dragon Knight
* Heroes with strong area-of-effect damage can make quick work of Chen's converted creeps and at same time gain farm: 
Magnus, Jakiro, 
Shadow Fiend, 
Kunkka, 
Luna, Dragon Knight, 
Medusa, Alchemist.
Bounty Hunter
* Track allows Bounty Hunter to keep Chen under watch whenever he jungles and to give Bounty Hunter and his allies a huge gold gain whenever Chen is killed while under effects of Track.
* Shadow Walk allows Bounty Hunter to bypass Chen's creeps and sneak on Chen and finish him off with Jinada and 
Shuriken Toss.
* However, Bounty Hunter's single-targeted ability arsenal can make it difficult for him to clear waves of Chen's creeps.
Dragon Knight
* Shadow Fiend's 
Presence of the Dark Lord reduces Dragon Knight's armor considerably, and his strong base attacks are augmented by his 
Necromastery.
Dragon Knight
* Dragon Tail can be used to cancel Requiem of Souls.
* Breathe Fire reduces Shadow Fiend's damage even further.
* Dragon Knight's high strength and Dragon Blood means that he'll be able to tank Shadow Fiend's right clicks.
Bounty Hunter
* Bounty Hunter can absolutely destroy a Shadow Fiend's game by ganking his midlane with Shadow Walk, Jinada and Shuriken Toss.
* If his lane goes bad, a Shadow Fiend usually goes to the jungle. Follow him with Shadow Walk and take half of his experience.
* Due to its ministun, Shuriken Toss is a good way to interrupt Shadow Fiend's long cast animation on 
Requiem of Souls.
Additional:
* Shuriken Toss can be used to cancel Requiem of Souls.
* Shadow Walk and Jinada allow Bounty Hunter to gank Shadow Fiend early on
* Track prevents Shadow Fiend from escaping with Shadow Blade.
Dragon Knight
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,
Bloodseeker, Lifestealer, Troll Warlord, Sven
Bounty Hunter
* Heroes that can prevent Sven from farming are very strong against him. Such as Riki and Bounty Hunter with their respective invisibility.
Dragon Knight
* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and 
Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Additional:
* The extra damage from 
Searing Arrows is largely blocked by Dragon Knight's armor.
* Clinkz has too low health to survive a gank.Getting stunned keeps him down long enough for a reaction.
* Breathe Fire reduces his damage,as it is physical.
Bounty Hunter
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:Clinkz, Riki, Treant Protector, etc.
Additional:
* Track reveals Clinkz if he tries to escape with Skeleton Walk, allowing Bounty Hunter to gain lots of gold if he kills Clinkz.
* Jinada with physical damage items can quickly kill Clinkz due to his low health.
Bounty Hunter
* Sniper relies on distance. Bounty Hunter can use Shadow Walk to get close, and Jinada can do massive damage and slow down Sniper in the early game.
* Track gives additional speed to Bounty Hunter and makes Shadow Blade useless, which can allow Bounty Hunter to easily kill him with a few attacks.
Bounty Hunter
* Track detects Mirana and her allies during Moonlight Shadow.
Bounty Hunter
* Bounty Hunter can easily keep vision on Pudge with Track, making it difficult for Pudge to hook Bounty Hunter or his team mates.
* It's difficult for Pudge to keep up with Bounty Hunter to apply 
Rot on him due to Shadow Walk.
* Shuriken Toss cancels out 
Dismember from a good range if Bounty Hunter is not the target.
Additional:
* Track can easily keep vision on Pudge, making it very hard for him to hook Bounty Hunter or his teammates from the fog of war.
* Shuriken Toss cancels Dismember from great range.
Dragon Knight
* If Silencer can't prevent Dragon Knight from using Elder Dragon Form, Silencer's spells aren't going to be that effective against him, as Dragon Knight relies on right-clicks and not spells.
* Dragon Blood's armor bonus and health regeneration allows Dragon Knight to stay in the lane against Glaives of Wisdom.
* Dragon Knight often builds Black King Bar, allowing him to remove Global Silence before engaging.
Dragon Knight
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord, Sven
Dragon Knight
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, 
Night Stalker, Centaur Warrunner, Wraith King and more.
Bounty Hunter
* 
Monkey King is also hindered by Track since he relies on trees to hide him from vision.
Additional:
* Track grants vision of Monkey King, even when he's in the trees.
Dragon Knight
* Any hero who can survive Magnus's initiations and manfight him: Huskar, 
Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, 
Viper.
Bounty Hunter
* Bounty Hunter with Track.
* Windrun invisibility via Aghanim's Scepter is very risk from Windranger against Hero True Sight abilities
* Bounty Hunter with Track.
* Slardar with Corrosive Haze.
* Bloodseeker with 
Thirst.
Bounty Hunter
* Bounty Hunter and Slardar both have ultimates (Corrosive Haze and Track) that reveal Invoker through Ghost Walk.
Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, Pugna, 
Skywrath Mage, 
Io, Witch Doctor, etc.
Dragon Knight
* Heroes that reduce the damage that Marci can deal during her ultimate, like 
Razor, 
Rubick, Bane, Dragon Knight and Underlord.
Bounty Hunter
* Heroes who can provide True Sight or semi-reveal enemy heroes as Nature's Prophet is prone to buying Shadow Blade: Bounty Hunter, Slardar, Spectre, 
Zeus, Spirit Breaker.
Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, Pugna, Skywrath Mage, Io, Witch Doctor, etc.
Dragon Knight
* Dragon Knight's insanely high armor and splash damage can cause Lycan to struggle taking him down.
Dragon Knight
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord, Sven
Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, Pugna, Skywrath Mage, Io, Witch Doctor, etc.
Bounty Hunter
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:Clinkz, Riki, Treant Protector, etc.
Bounty Hunter
* Phantom Lancer with Doppelganger
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Additional:
* Doppelganger dispels Track.
* Bounty Hunter also has no area of effect abilities to help with the illusions.
Dragon Knight
* The dragon's splash damage wears down his illusions.
* Early harassment with Breath of Fire hinders his farming.
* Fireball stops his pushes and allows for a defence.
Additional:
* Breathe Fire and Elder Dragon Form's splash damage takes out Phantom Lancer's illusions quickly.
* If Dragon Knight can Dragon Tail the real Phantom Lancer, he and his team can quickly kill him before he has a chance to escape.
Bounty Hunter
* Frostbite will reveal invisible heroes for its duration, making it a good tool against any such hero (Riki, Bounty Hunter, Weaver, or Clinkz for example), or as a soft counter to Shadow Blade, if it is used first. This can be an amazing tool to ensure that Dust of Appearance is used on the unit in question, and not wasted in not catching anything.
Bounty Hunter
* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, Sniper, Ursa, Witch Doctor, etc.
Additional:
* Shuriken Toss's stun is useful for cancelling Freezing Field from a distance.
* Track can be used for revealing Crystal Maiden when she uses 
Glimmer Cape.
* Jinada does burst physical damage (which is even bigger if dealt under Track's crits), which is effective due to Crystal Maiden's low HP and armor.
* Bounty Hunter likes to stay hidden from the fight and is less likely to get caught by Crystal Maiden's spells.
Bounty Hunter
* Juggernaut with Blade Fury
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Dragon Knight
* Heroes with high armor and/or durability can handle Juggernaut's ultimate, such as Sven and Dragon Knight.
Bounty Hunter
* Heroes with invisibility will be detected by Thirst when they have low enough health: Bounty Hunter, Templar Assassin, Riki, Clinkz, Weaver, Treant Protector, Nyx Assassin.
Additional:
* 
Rupture can turn Bounty Hunter's mobility against him, and prevents him from escaping with Shadow Walk due to the potentially heavy damage.
* Thirst can prevent Bounty Hunter from escaping with Shadow Walk should Bounty Hunter's health become low enough, as it provides True Sight.
Dragon Knight
* 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.
Bounty Hunter
* Weaver with Time Lapse
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Bounty Hunter
* Bounty Hunter has a cheap way to break Linken's Sphere and keep track of Weaver while he is using Shukuchi, though both can be dispelled with Time Lapse.
Bounty Hunter
* Spirit Breaker's 
Charge of Darkness semi-reveals Bounty Hunter, taking away his element of surprise for the duration of the charge. Also, as Charge of Darkness shows Bounty Hunter's position, Spirit Breaker's allies can proceed to gank Bounty Hunter while he is roaming alone.
Dragon Knight
* Spirit Breaker's slow attack speed and moderate damage do very little to harm Dragon Knight, even if ganked with Charge of Darkness.
Bounty Hunter
* Lifestealer with Rage and Infest
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Dragon Knight
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord, Sven
Dragon Knight
* 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.
Additional:
* 
Cold Feet and 
Ice Vortex both hinder Dragon Knight's movement greatly during teamfights.
