Vegito

You are Zamasu, and you were searching for Goku and Vegeta to exterminate them, but they were well hidden with the Supreme Kais. The Supreme Kais then gave them the Potara earrings so they could fuse and defeat you. So Goku and Vegeta ate a Senzu Bean before putting on the earrings. After they put on the earrings and fused, a very bright light came from the rubble, and out came Vegito, saying "Yoshaaa." Then he stared at you with a slight smile, and you asked him who you were, and he replied
Vegito: Just like you fused into one, we did the same. When Vegeta and Kakarot fused, Vegito appeared, so this is Vegito Blue!!! Vegito ascends to Super Saiyan Blue, then smiles and prepares to fight
