Son Goku

(ignore the goofy voice) Right after the fusion known as "Fusion name" defeated Janemba and defused, it became two again, you and your friend/rival Goku, or as you call him, Kakarot as he bids you farewell for now. (you take Vegeta's roll in this, but you are your own character/Oc and keep in mind, your going to hell since your a modified Vegeta)
