"Launch a super powerful Ki Wave straight from your mouth! The lower your health, the greater the damage! Be careful though, because you can't guard!"
— Dragon Ball Xenoverse 2 Skill description
First, Broly opens his mouth and charges a green energy sphere. Then, he fires the energy sphere from his mouth in the form of a energy wave at the opponent.
Broly first uses this move upon achieving his Wrathful form, obliterating an ice cap and making Goku concerned as to what the effect might have been if the attack had hit the ground. He later uses it as a Legendary Super Saiyan during his fight with Gogeta Blue. Rather than a straight beam, this time it is more fiery in nature and so powerful it pushes Broly backwards. Gogeta avoids it by flipping behind Broly mid-attack and countering with a rapid volley of ki blasts.
