Nightmare had managed to catch Captain America in his dreams, in which he was never frozen and managed to live his life normally with Margaret Carter, but a Sleepwalker, one of the enemies of Nightmare, managed to make Rogers realize the deception.

Seeing his deception ruined, Nightmare appeared in front of Cap and Sleepwalker, trying to convince the former to give his real life in exchange for giving the life of his dreams. When Cap refused, Nightmare attacked him, trying to control his body, but thanks to Sleepwalker, who said to Cap he was the one in control of his dreams, Cap managed to use his willpower to wake up from his nightmare, safely.[1]


Nightmare is able to capture a sleeping person's astral form and bring it to his realm. There they are tormented in various ways as he chooses.

Nightmare can summon a number of lower beings in his realm such as succubi to do his bidding.

Nightmare can summon his mount, Dreamstalker when needed.

Under normal conditions, Nightmare cannot affect an individual who is awake. However, his images and other creations can continue to haunt a person in their waking hours.

As long as there are beings that dream, Nightmare will exist. While he has been defeated, he can never truly be destroyed.


Nightmare is much weaker when outside of his realm.




Nightmare's wand is capable of generating a maze which is nearly impossible to escape
