I don't know too much about Vegetto, but I'll tell you what I do know. Vegetto is a fusion of Vegeta and Goku, with Vegeta in control of the body. Vegetto waists a lot of time in battles, which gives the enemy the advantage, which sounds just like Vegeta if you ask me. But he is a powerful warrior. He uses both Vegeta and Goku's attacks together in battle, the famous attack known as the Big Bang! More to come soon...
