Vegitto is the combination of Goku and Vegeta. This is the second fusion between them. This fusion happens when Vegeta and Goku are battling Buu, and Buu almost defeats them when Vegeta is forced to obtain the Pattaro earring and put one of them on. So Vegeta does so, and Goku puts the other Pattaro earring on the other ear. Then, after that, Vegitto comes to play. This fuse was supposed to last them a life time, but when Vegeta has an accident, he breaks one of the earrings, and poof, they come un-fused. I liked Vegitto, he was kinda cool.
