Trunks

Trunks (トランクス, Torankusu) is a fictional character from the Dragon Ball franchise by Akira Toriyama. Trunks is the half-Saiyan son of Vegeta, the prince of the dying race of fictional aliens called the Saiyans, and Bulma, the heir of a massive company called Capsule Corporation. In keeping with the family's tradition of using underwear puns for names, Trunks' name is derived from the term for men's swim shorts.

In Super Smash Flash 2
Trunks makes a minor cameo appearance in the stage, Planet Namek, of Super Smash Flash 2. He usually appears flying in the sky alongside his father Vegeta and Gohan, but as the other two, he is merely just a stage decoration and doesn't affect the match in anyway.
