Emperor's Edge is a stronger variation of the Death Wave technique used by Golden Frieza in Dragon Ball: Xenoverse.
Overview
The user fires a fiery gold & red slashing Energy wave at the opponent. As soon as it hits the opponent, a large explosion in the shape of a blade appears, knocking away the opponent.
Golden Frieza uses Emperor's Edge twice during his battle with Goku. While fighting Super Saiyan God SS Goku atop a mountain, he fires the attack at him, despite not being a direct hit, The incredible power put out by Golden Frieza's attack knocks back and injures Goku. When Goku drops back into his Saiyan beyond God form and the other Z Fighters attempt to help him against the tyrant, Golden Frieza uses his Emperor's Edge again in order to stop them from getting any closer.
