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 claded with sirens almost everywhere suggesting a symbol of enforcement of law.

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 dies when Joker self-destructs to save the lives of Geo and others.
