The Blutz Wave Generator is a machine that fires Blutz Waves. It was built by Bulma while she was under Baby's control, and it was used to turn Baby into a Golden Great Ape. He could turn into one only because he was inside of Vegeta's body, and Vegeta is a Saiyan. Later during the fight with Omega Shenron, Vegeta uses the same machine to advance to Super Saiyan 4, since he lacked a tail.
