Chibi Trunks, the son of Bulma and Vegeta, turns super saiyan very young, like Future Trunks. He is best friends with Goku's second son, Goten, and loves to cause trouble. He dreams of monsters and bad guys like his mom and dad tell him about from the past, and is a dream come true when Babidi and Buu arrive to conquer and destroy the planet. He even gets his chance to save the world when he fuses with Goten to fight against Buu, but doesn't turn out on top due to having too big an ego, knowing he could've killed Buu.
