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.
- 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 went Great Ape for the second time during the training for the fight against the Saiyans.
- Many fans consider the Blutz Wave Generator to be contradictory in that it is established in Saiyan apochrypha that transforming into the Great Ape is not possible without the Saiyan tail, as the tail possesses the glands necessary for the transformation. Regardless of how many Blutz Waves were absorbed, a transformation should not be possible if the Saiyan does not have the tail. It is arguable that while possessed, Vegeta was able to transform into the Golden Great Ape because of some influence of Baby's DNA. But during the Shadow Dragon Saga, Vegeta somehow manages the transformation without the tail.
