Zexion

Zexion's original self was Ansem the Wise's youngest lab assistant, and named Ienzo (イエンツォ, Ientso?). He convinced Ansem the Wise that they should build an underground lab for research. He is voiced by Akira Ishida in Kingdom Hearts Re:Chain of Memories. Zexion uses his power of illusion, used to mimic others' weapons, disguise himself as others, and create duplicates of himself.[6] His unique weapon is a lexicon. Before Kingdom Hearts II Final Mix, Zexion's weapon and powers were unknown because he had died without fighting.
