Chaotic Tyrant (カオティックタイラント Kaotikku Tairanto) is a rush attack used by Bojack in his base form.
Bojack right-hooks the opponent, and proceeds with a double axe handle. Next, he kicks the opponent in the air and finishes with a left hook kick away, inflicting a great deal of damage.
Bojack uses this attack against Vegeta in the movie Dragon Ball Z: Bojack Unbound. After Future Trunks is saved by his father, Bojack engages Super Saiyan Vegeta in a Ki Blast battle. Bojack proceeds to fire a Full Power Energy Ball at the Saiyan prince, who is hit head-on by it. After Vegeta tells Trunks to stay back, after he tries to help, Bojack does the "Chaotic Tyrant" rush on him, knocking him through a building, where Future Trunks saves him.
