Yi Xing Long, also known as Syn Shenron in the Funimation dub, is the final antagonist of the Dragon Ball GT anime series. He is the last of the Shadow Dragons and the dragon of the One Star Ball. Syn Shenron later becomes Super Yi Xing Long, Omega Shenron in the Funimation dub, after he absorbs all the other Dragon Balls and gains the powers of the other Evil Dragons, allowing his strength to increase 10x what it originally was.
He is the third/last of the three arch-villains in Dragon Ball GT and the main antagonist of the Shadow Dragons Saga.
