The Omni-King is the most powerful being in the Dragon Ball multiverse, and one of the strongest fictional characters of all time. Zeno may not have created the multiverse in Dragon Ball — that honor goes to Lord Rymus from Dragon Ball DAIMA — but he can destroy it like it's nothing if he's in a bad mood. At the end of the Goku Black Saga, Zeno effortlessly erases every universe in Future Trunks' timeline, reducing the world to nothing... except himself.
