"Though its origins are vague, Double is devoutly loyal to The Trinity, using its shape-shifting powers to support The Trinity's ominous agenda. As such, it is an ally of the Skullgirl. Double is capable of transforming its nightmarish form into that of any person, but it often takes on the appearance of a smiling nun. Double can frequently be found in the Grand Cathedral of the Divine Trinity, listening to confessions and tending to the catacombs beneath. "
