A.C. Eos

A.C. Eos, known as Shidō Akatsuki (暁シドウ) in Japan and often referred to by the nickname Ace, is a Zero Satella Police officer. As one of Geo and Omega-Xis's allies, he can be fought. He can EM Wave Change with his Wizard, Acid, to become Acid Ace. The two are registered under the Satella Police's Project TC as No. 001. He is the creator of Hunter VG, the device that succeeds Transers and Star Carriers as well as allowing Wizards materialize.

Due to Acid being a man-made Wizard and not a natural EM Being, wave changing puts a tremendous strain on Ace's body, to the point where Acid will voluntarily revert the wave change in order to protect Ace.

Despite his generally cheerful and goofy demeanor, he used to be a member of Dealers before leaving and joining the Satella Police. In the past, he used to have a romantic relationship with Queen Tia.

He supposedly dies when joker blows up in Dealers hideout but fans are skeptical, since when the credits roll, a picture of Ace can be seen, being in a hospital, being taken care of by Dr. Goodall and Queen Tia, suggesting they found data frags of him and reassembled him and Acid like they did with Luna.

Name
Dr. Goodall often refers to A.C. Eos as Arthur, implying that to be his first name, and making his full name Arthur C. Eos. In Greek mythology, Eos is a titan and the goddess of the dawn.

A.C. Eos' initials spell the word Ace, which is often used as his nickname, and is a direct reference to the playing card of the same name. Ace is also a term used for someone of great skill in things such as sports or shooting.

Trivia

 * After trying a Mega Snack, A.C. Eos becomes very fond of them. He is seen throughout the game munching on one or several whenever he has time to do so, to the point that it worries Acid.
