Baby

Baby was a Parasitic Tuffle able to infect nearly everyone on earth to do his bidding and decided to use Vegeta's body as his main source of power. However, he was defeated by SSJ4 Goku. When Arkicho gave power to everyone in Hell, he broke free and was able to face his own against the Z-Fighters until Vegeta and Goku fused into Super Gogeta (Ascended Super Saiyan Gogeta), so he decided to try to go in as he managed to gain control. He started testing out the forms. However, they managed to push him out and send him back to Hell with a Big Bang Kamehameha X100.
