Crisis

Crisis's powers and abilities

Intelligence - Crisis is a devious schemer who was behind all of the machinations of Reverend Darrk. He is patient and will only engage when he has the advantage.

Reality Merging - Crisis is capable of merging realities he intends to conquer with his home realm of Dreamworld. This is a gradual process and should he be defeated, it will be reversed.

Size and Strength - Crisis in his normal form is a giant, capable of tanking hits from the entire Earth 6 JLA with little issue. Each of his landed blows were also crippling to anyone he fought. He is also capable of reducing his size, but he only does this when he is not under threat.

Purple Magic - Crisis's purple-hued magic has many possible effects from trapping his opponents in endless nightmares, disintegrating them, breaking them out of transformations or surrounding them with massive amounts of heat. The blasts can also just be raw blasts of power. His magic appears to be capable of doing most things that he wants.

Crisis's weaknesses

Sapphires - Breaking or otherwise removing the sapphires in Crisis's armor can weaken him significantly, although even after several were damaged he was still too much for the Earth 6 JLA.

Arrogant - Once Crisis believes he has won, he has a tendency to let his guard down. He did this multiple times during his fight with the JLA and it ultimately resulted in his defeat.
