The Blutz Wave Generator is a machine that fires Blutz Waves. It was created by Bulma.
Overview
The Blutz Wave Generator was built by Bulma while she was under Baby's control, and was used to turn Baby into a Golden Great Ape without the need of a tail. Later, during the fight with Omega Shenron, Bulma uses the same machine on Vegeta to advance him to Super Saiyan 4, since he lacked a tail. The Generator was destroyed by Omega Shenron's Finger Beam after Bulma tried to attack him with Blutz Waves in order to defend Trunks.
Trivia
A similar device existed on the Saiyan's Attack Balls, where it would generate a holographic representation of a moon for use on the occupants when its onboard computer awakens the Saiyan occupant, as evidenced by what happened when Gohan transformed into a Great Ape for the second time during the training for the fight against the Saiyans.
