* 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.
Razor
[wiki] rating: 1.0 (winrate: 49% pickrate: 1%)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.

Fury swipes can tear Dragon knight down as it stacks infinitely.
Outworld Devourer
[wiki] rating: 1.0 (winrate: 47% pickrate: 3%)Dragon Knight

Sanity's Eclipse, which also bypasses his armor.
Bristleback
[wiki] rating: 1.0 (winrate: 45% pickrate: 5%)Dragon Knight
* 
Viscous Nasal Goo slows down Dragon Knight and lowers armor, locking him down and making him more vulnerable.
Underlord
[wiki] rating: 0.6 (winrate: 56% pickrate: 10%)Dragon Knight

Undying, 
Alchemist, 
Legion Commander.

Huskar
[wiki] rating: 0.6 (winrate: 50% pickrate: 3%)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,

Additional:
* Huskar can negate Dragon Knight's passive with multiple trades of Burning Spear.
Omniknight

[wiki] rating: 0.4 (winrate: 52% pickrate: 7%)Dragon Knight
* 
Heartstopper Aura and 
Reaper's Scythe go right through Dragon Knight's armor.
Dragon Knight

Phantom Lancer
[wiki] rating: -1.0 (winrate: 47% pickrate: 5%)Dragon Knight
* Breathe Fire and Elder Dragon Form's splash damage takes out Phantom Lancer's illusions quickly.

Dragon Tail the real Phantom Lancer, he and his team can quickly kill him before he has a chance to escape.
Witch Doctor

* 
Death Ward does little damage against Dragon Knight's armor, and Dragon Knight's high health regeneration minimizes damage from 
Maledict.
Silencer
[wiki] rating: -1.0 (winrate: 48% pickrate: 6%)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.
Templar Assassin
[wiki] rating: -1.0 (winrate: 49% pickrate: 6%)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.
Nyx Assassin
[wiki] rating: -1.0 (winrate: 49% pickrate: 3%)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.

Charge of Darkness.
Bloodseeker
[wiki] rating: -1.0 (winrate: 52% pickrate: 6%)Dragon Knight
* 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.
Riki
[wiki] rating: -1.0 (winrate: 53% pickrate: 5%)Dragon Knight
* Riki does little damage to Dragon Knight, as he relies only on physical damage with modest attack speed and lack of burst.

[wiki] rating: -1.0 (winrate: 57% pickrate: 10%)Dragon Knight
* The extra damage from 
Searing Arrows is largely blocked by Dragon Knight's armor.

* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord

* High armor thanks to Dragon Blood makes it difficult for Phantom Assassin to burst down Dragon Knight, as she deals 100% physical damage.
* Dragon Tail stuns Phantom Assassin as soon as she initiates, preventing her from gaining bonus attack speed.
* Dragon Knight is one of the few heroes who can safely solo lane against Phantom Assassin alongside a support.
Naga Siren
[wiki] rating: -0.6 (winrate: 48% pickrate: 2%)Dragon Knight
* Cleave heroes will clear her illusions. Such heroes include Sven, Magnus, Dragon Knight in Elder Dragon Form,

Mars, Centaur Warrunner.
Broodmother
[wiki] rating: -0.6 (winrate: 55% pickrate: 3%)Dragon Knight
* 
Broodmother's spiderlings and spiderites do almost nothing against Dragon Knight.
Additional:
* Breathe Fire will clear Broodmother's spiderites while significantly damaging her spiderlings and decreasing their damage output.
* Dragon Blood's added armor and regen mitigates the damage done by Broodmother and her spiders.

Shadow Fiend
[wiki] rating: -0.4 (winrate: 48% pickrate: 11%)Dragon Knight

Necromastery.
Dragon Knight

* Dragon Knight's high strength and Dragon Blood means that he'll be able to tank Shadow Fiend's right clicks.
