Hakai-O Ouga LBX
Gao Cannon (我王砲（ガオーキャノン） Gaō Kyanon) is an EX attack function introduced in Danball Senki series.
Hakai-O charges its energy in its centre breast cannon, then fires at the opponent with destructive force. Its only demerit is that all functions are temporarily ceased after firing, making it vulnerable towards its opponents.
Danball Senki Wars
It was first used by Hakai-O in Episode 3, and managed to destroy Kazu's Warrior.
