Dodoria raises his hands and charges a yellowish-orange energy sphere. Then, he brings his hands forward (saying either "You're outta here!" or "Just go down already!"), and charges an energy sphere that he then fires in the form of a large wave of energy at the opponent, inflicting a great amount of damage.
Dodoria uses this attack in an enraged attempt to destroy the hidden Krillin, Gohan, and Dende on Namek, blasting the beam downwards on the little patch of land Krillin, Gohan and Dende are on. Although Dodoria believes he succeeded in killing them and flies off, Krillin, Gohan, and Dende actually managed to escape the blast in time by flying above Dodoria. Dodoria later uses the Maximum Buster during his battle against Vegeta, however, Vegeta easily dodges it and threatens to break Dodoria's arms from behind. In an attempt to save himself, Dodoria begs for mercy and offers to reveal the truth about Planet Vegeta's destruction if Vegeta spared him.
