The Galactic Buster is Bojack's ultimate move that he used in the movie Bojack Unbound. When he uses it, he forms two bright-green energy spheres on his hands and spreads his arms out in a form similar to Vegeta's Final Flash technique. He then throws the energy balls out at his opponents in the form of a massive wave of energy. This attack is named in the Budokai Tenkaichi video game series and is also Bojack's Ultimate Blast in his Full Power form. From Dragon Ball Wiki, a Wikia wiki.
