- out-heals Doom to a large degree throughout all stages of the game. Should Alchemist be chemically enraged before being Doomed, Alchemist can become a difficult target to effectively lockdown and kill, thanks to the health regeneration and movement speed bonuses granted by his ultimate.
- Alchemist is an ineffective target for Doom. Alchemist isn't totally reliant on his skills to be effective during a teamfight, due to the right-click nature of the hero.
- can be used to free an ally from the grasp of Doom. Without any means of effective lockdown, kills can be difficult to secure when against an enemy Centaur Warrunner.
- Drow Ranger can be difficult to get on top of, thanks to her and . With these two abilities, Drow Ranger is able to effectively 'kite' Doom and minimize his impact during team fights and laning stage.

- Doom has no effective means of escape from . This is particularly devastating in lane, where Doom may have to play a much more passive, conservative play style as a result.

- Doom does not disable . As such, Doom's damage is largely mitigated by her mana shield. Additionally, Medusa is not reliant on her abilities to be effective during a teamfight, making Medusa an unproductive hero to target.
- Medusa is an ideal carrier. Should one be purchased, and without any additional disables, Doom may find that few opportunities exist to effectively lockdown, disable, and kill Medusa.

- Phantom Lancer's illusions can make it difficult to Doom the original. Should Doom figure out the original hero, the illusions can make it difficult to cast any abilities, as their hitboxes can be used to body-block the Phantom Lancer.
- Phantom Lancer is an ideal carrier. With it, he can quite easily deplete Doom's already poor mana pool, potentially making him unable to cast his abilities to escape, retaliate or heal.
- Doom lacks any effective ability to clear waves of creeps and illusions, as the vast majority of his abilities are single-target. Without an answer, Doom may find it difficult to deal with Phantom Lancer's presence.
- Due to the nature of the hero, Sniper is typically situated in the back of the fight, potentially making him a difficult target to initiate on and fight.
- Sniper is largely a right-click hero, and as such isn't as an effective of a Doom target as other heroes.
- Thanks to and , Sniper is able to effectively 'kite' Doom, preventing him from closing the distance between the two.
- The slow applied from offsets the movement speed bonus granted by Scorched Earth and the tick-based damage from Infernal Blade and Doom will continually slow Doom down. This allows Viper, much like Sniper, to 'kite' Doom and keep him at a safe distance between the two. Additionally, applies an attack-speed slow which is fairly crippling to a hero such as Doom that, naturally, has a high base attack-time, poor agility gain and builds little attack-speed items.
- Since Doom does not disable auto-cast abilities, Viper's will continue to work. Doom may find it hard to close the distance between himself and Viper, and thusly difficult to effectively lockdown and continually deal damage through his abilities.
- Wraith King has three passive abilities and only a single active ability, so Doom does not hinder him significantly.

- Infernal Blade deals scaling damage and is useful against high HP targets such as Axe.

- Doom has naturally high HP so it takes longer for Doom to be brought down to the killing threshold of .
- Axe is highly reliant on his abilities and items to be effective during a fight. Without the usage of and , Axe offers very little in the way of damage.
- Infernal Blade deals scaling damage and is useful against high HP targets such as Timbersaw.
- Timbersaw is extremely reliant on his abilities to be effective during a teamfight - both for mobility, damage and crowd control. Timbersaw offers very little impactful right-click damage, and thus Doom is particularly crippling against this hero.
- Additionally, when upgraded with , Infernal Blade breaks , which effectively removes the durability which Timbersaw is commonly known for.
- Doom prevents Anti-Mage from maneuvering around a fight or escaping from an initiation using
