Ursa
[wiki] rating: 2.0 (winrate: 52% pickrate: 15%)Outworld Destroyer
[wiki] rating: 2.0 (winrate: 51% pickrate: 10%)Kunkka
* 
Astral Imprisonment can allow Outworld Destroyer to save himself or allies from Kunkka's full kit.
* 
Sanity's Eclipse deal a large amount of damage, as Kunkka's mana pool is much smaller than Outworld Destroyer's.
* 
Arcane Orb deals pure damage, shredding through Kunkka and his team even with Ghostship's buff.
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.
Omniknight
[wiki] rating: 1.6 (winrate: 55% pickrate: 3%)Kunkka
* 
Guardian Angel makes allies immune to all physical damage, effectively causing Tidebringer to do no damage.
* 
Purification is a powerful, pure damaging heal that can save Omniknight's allies after Kunkka's large damage.
Dragon Knight
* Heroes who rely strongly on melee physical damage will fare badly against Omniknight's Guardian Angel:

Juggernaut, 
Dragon Knight, 
Lycan, 
Ursa, 
Troll Warlord
Huskar
[wiki] rating: 1.6 (winrate: 53% pickrate: 6%)Kunkka
* Since Tidebringer has a 4 second cooldown, Kunkka has little availability to manfight Huskar.
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.
Viper
[wiki] rating: 1.6 (winrate: 49% pickrate: 4%)Kunkka
* Melee heroes with low mobility can be kited and killed by Viper: 
Treant Protector, 
Kunkka, 
Alchemist, Troll Warlord,

Black King Bar is basically defenseless against Viper.

Poison Attack.
* 
Corrosive Skin reduces damage from Dragon Fire and inflicts damage to him.
* 
Nethertoxin disables Dragon Blood, negating his main survivability.
*

Additional:
* Dragon Knight is easily harassed by Poison Attack after the laning stage ends.
* Corrosive Skin protects Viper from 
Breathe Fire and returns damage.

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.
Shadow Demon
[wiki] rating: 1.2 (winrate: 47% pickrate: 1%)Kunkka
* Similarly, they can negate your X Marks The Spot & Torrent combo by protecting your target when you use Return. Good candidates to negate your combo include 
Outworld Destroyer and his Astral Imprisonment, and 
Shadow Demon and his 
Disruption.
* Heroes with hide abilities can often dodge a Ghostship just before it hits.
* Similarly, they can negate your X Marks The Spot & Torrent combo by protecting your target when you use Return. Good candidates to negate your combo include Outworld Destroyer and his Astral Imprisonment, and Shadow Demon and his Disruption.
* A 
Eul's Scepter of Divinity can also do the trick, but, unlike the previously mentioned abilities, you can only use it on yourself and not your allies.
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.

Leap allows Mirana to easily escape Torrent and Ghostship.
Razor
[wiki] rating: 1.0 (winrate: 52% pickrate: 7%)Dragon Knight

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.
Drow Ranger
[wiki] rating: 1.0 (winrate: 51% pickrate: 18%)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 Shard, 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)
Lich
[wiki] rating: 1.0 (winrate: 51% pickrate: 9%)Dragon Knight
* Lich's constant slows with 
Frost Blast and

Phoenix
[wiki] rating: 1.0 (winrate: 50% pickrate: 5%)Kunkka
* 
Supernova negates Kunkka's combo entirely, as it can't be affected by spells while using Supernova.
* 
Icarus Dive also allows Phoenix to dodge Ghostship and Torrent.
Rubick
[wiki] rating: 1.0 (winrate: 47% pickrate: 25%)Kunkka
* Kunkka is a strong teamfighter with his powerful control spells, which Rubick could exploit to his advantage.
* 
Torrent provides another source of damage and crowd control.
* 
Ghostship is a powerful teamfight spell, providing huge magical damage to enemies and buffing allies with damage negation.
* Both skills works the best when comboed with other source of control from allies, such as 
Duel or 
Beserker's Call.
* 
Telekinesis can reposition an enemy onto a Torrent or Ghostship.
* 
Torrent Storm works as a disruptive spell for Rubick to create chaos around him.
* 
Tidal Wave offers another source of control and repositioning.
* As long as Kunkka gains these spells with Aghanim's Shard and Aghanim's Scepter, 
Rubick does not need extra items to steal these spells.
* 
X Marks the Spot serves as a utility spell for escaping, chasing and other useful functions.
Timbersaw
[wiki] rating: 1.0 (winrate: 46% pickrate: 5%)Dragon Knight
* Timbersaw's pure damage will kill Dragon Knight surprisingly fast, especially if he gets caught in a bad position while laning.
Sniper
[wiki] rating: 1.0 (winrate: 44% pickrate: 11%)Kunkka
* With his 
Take Aim, Sniper can simply sit out of your ability range and deal massive damage if not killed first.
* 
Assassinate can target allies who are still alive with low health because of Ghostship's buff.
* 
Headshot makes it harder for Kunkka to position/escape and makes it hard for Kunkka to hit with Tidebringer.
Bristleback
[wiki] rating: 1.0 (winrate: 43% pickrate: 1%)Dragon Knight

Living Armor will also negate Tidebringer's damage.
Venomancer
[wiki] rating: 0.6 (winrate: 50% pickrate: 4%)Dragon Knight

Venomancer and others in addition to the heroes mentioned above.
Gyrocopter
[wiki] rating: 0.6 (winrate: 50% pickrate: 7%)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.
Slardar
[wiki] rating: 0.6 (winrate: 50% pickrate: 4%)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.
Elder Titan
[wiki] rating: 0.6 (winrate: 50% pickrate: 1%)Dragon Knight
* 
Elder Titan's 
Natural Order completely nullifies Dragon Knight's high armor.
Ancient Apparition
[wiki] rating: 0.6 (winrate: 50% pickrate: 5%)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.
* 
Ice Blast ignores Dragon Knight's armor, disables his health regeneration, and kills him prematurely.
Pangolier
[wiki] rating: 0.6 (winrate: 48% pickrate: 9%)Dragon Knight
* Heroes who rely on skills to become a heavy hitter in a certain amount of time can waste their timing because of a lucky Lucky Shot's disarm:

Clinkz, 
Windranger, Alchemist, Dragon Knight, 
Legion Commander
Clinkz
[wiki] rating: 0.4 (winrate: 52% pickrate: 7%)Kunkka

Searing Arrows together can kill allies easily even under Ghostship's buff.
* 
Skeleton Walk can allow Clinkz to make a quick escape after Kunkka's combo, or even avoid it all together.
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.
Necrophos
[wiki] rating: 0.4 (winrate: 50% pickrate: 7%)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.

[wiki] rating: 0.4 (winrate: 50% pickrate: 11%)Kunkka
* 
Blade Fury negates Kunkka's X Marks the Spot.

Bloodseeker, 
Lifestealer, Troll Warlord, Sven

Templar Assassin
[wiki] rating: -1.0 (winrate: 48% pickrate: 4%)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.

* Dragon Knight can simply tank and destroy all Shadow Shaman's Serpent Wards.
Nyx Assassin
[wiki] rating: -1.0 (winrate: 50% pickrate: 4%)Dragon Knight

* X Marks the Spot is good to prevent a single meepo from escaping from a deadly situation.

Additional:
* X Marks the Spot can be used to prevent Tinker from escape with 
Blink Dagger or 
Boots of Travel, discourage him from snapping farm and snapping gank. However, in later game, it'll be much more difficult because Tinker can buy Black King Bar or Linken's Sphere to prevent Kunkka from placing X on him, or Eul's Scepter of Divinity to prevent the recall
Shadow Fiend
[wiki] rating: -0.4 (winrate: 48% pickrate: 18%)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.
Kunkka
* Ursa's massive physical damage can destroy Kunkka quickly.
Enrage can be activated before being hit by Ghostship to prevent most of the damage.
Earthshock slows Kunkka's movement speed. With no escape abilities, Kunkka is easy prey.

Fury swipes can tear Dragon knight down as it stacks infinitely.
