A.C. Eos

A.C. Eos, nicknamed Ace, known as Shidō Akatsuki (暁シドウ) in Japan, is a Zero Satella Police officer. As one of Geo and Omega-Xis's ally, he can be fought. He can transform with his Wizard, Acid. He is the creator of Hunter VG, the device that lets Wizards materialize to the new Transers and Star Carrier.

He can Wave Change with Acid to become Acid Ace, who looks somewhat like a Gundam robot clad with sirens almost everywhere suggesting a symbol of enforcement of law. However, 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 deactivate it before Ace is hurt.

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 sugggesting like luna they founf data frags of him and reassembled him and Acid.

Trivia

 * Dr. Goodall calls him Arthur.
 * He eats a LOT of Mega Snacks, to the point that Acid says he might be eating too many.
