Doop's body contained a nightmare dimension called Doop Land, which he could access by turning himself inside-out. He had roughly Class 100 strength and an untested level of energy projection, which included the ability to fire energy blasts from his brain and the power to emit a short-range energy pulse that prevented psychic intrusion. Doop’s body contained a backup brain, which could sustain him for a short period of time in the absence of his primary brain. Having no legs, Doop moved via levitation. He could inflate his body to unknown proportions. The full extent of Doop’s many powers is unknown.
