Grand Zeno (全王 Zen’ō, lit. “King of All”), the Omni-King, is the supreme ruler of all the Multiverse and seemingly its most powerful being. Since the events of the “Future” Trunks Saga, Zeno co-rules jointly with his future counterpart.

Zeno is very short and small, with a rather large oval-shaped head. He primarily has sky blue skin, except for two sections from his ears to the middle of each eye on both sides of his head, which are purple. He has small round eyes, and small rounded grey “ears”. His main attire is a magenta and yellow lined coat, with yellow pants and magenta shoes. He wears a black and white shirt underneath, with the kanji for “all” (全) on the front. He typically has a blank expression on his face.
