Percer is one of the Six Chaos Fragments. He is one of the few individuals who could tell Id is a male at first glance. He also defeated Id in their first battle. Percer at first sight seems like a passive, simple-minded and laid-back young man, but he is known to be proud and holds little regard for mortals and other races he sees as sub-par, including humans. He has expressed a particular hate of Elves. In his fight with Sword Heart Unified Id ripped and opened a fabric of time and space that resulted in a dimensional rift.
