Zen-Oh, also known as the Omni-King, is one of the most powerful beings in Dragon Ball Super and the ruler of all universes. He has a childlike personality, speaks in a simple and cheerful way, and is able to erase entire universes or even timelines with a thought. Although he appears innocent and playful, his immense power makes him feared by gods and mortals alike. He plays a major role in the multiverse storyline, especially in the Tournament of Power arc.
