This galactic beast tears through space and shows up like a mirage. This beast is controlled by Sweed, who aims to unlock the seal of Onyx with Zadime’s power. It releases the massive tesseract, the Tesseractone, from its body, which spins rapidly and absorbs surrounding objects and opponents’ energy from attacks. Additionally, it can emit beams from both hands, and the multiple protrusions on its back are capable of absorbing and neutralizing attacks.

When Ultraman Arc tries to catch Zadime with the Arc Sword Catcher, a U-shaped cover on the end of the Arc Eye Sword, Zadime retaliates by absorbing and neutralizing the light. It also lets out U-shaped beams from the protrusions on its back. The tesseract from Zadime’s body not only tackles opponents with spinning attacks, but also converts absorbed energy internally, firing off beams of intense power. The tail can create a dimensional rift in which Zadime dodges attacks, hides and also disappears from opponents.
