Acid

Acid (アシッド) is the Wizard counterpart of officer A.C. Eos (Shidō Akatsuki in the Japanese version). Not much is known about him only that he has a panther-like appearance. He can Wave Change with his partner to become Acid Ace. Unlike other EM beings, Acid is more material than EM waves. He is generally friendly, kind, and polite especially to Geo and Sonia along with their Wizards. He was corrupted by Noise, courtesy of Joker. He then forces an EM Wave Change with his partner, Shane, to become Acid Ace B/Illegal Acid.
