Character: double (skullgirls)
Double (JP: ダブル Daburu) is a monstrous, transforming creature working under the Trinity, responsible for ensuring that the Skull Heart falls into the "right" hands and manipulating events according to the goddesses' will. Her current guise is as a nun under the name Agatha Gloomfoil. She is a playable character and major antagonist in the fighting game Skullgirls. She often appears as the penultimate boss in every other character's story.
Double takes full advantage of her shapeshifting abilities in battle, freely shifting her mass into various weapons and appendages. In-game, she prefers to morph into the forms of other characters in order to perform one of their attacks (including some that were dropped from their movesets during development). Some of her abilities involve using the form of one character to begin an attack before shifting into a different character to utilize their attributes as a follow-up.
Double's shifting abilities enable her to manifest multiple separate bodies that she can control, as well as enormous forms that far exceed her usual mass. However, she appears to be unable to imitate certain supernatural abilities.
Double can mimic anyone's voice, and is capable of talking normally to appear as, for example, a nun or a stranger at a party, in order to spread rumors about the Skull Heart.
Double is one of the only characters who does not use a parasite, living weapon, cybernetics enhancements, or magical artifacts when she fights.
