Nail uses this attack during his battle against Frieza in a bid to stall him for Dende to deliver the Namekian Dragon Balls' password to Gohan and Krillin. Nail has his back turned to Frieza and has a short conversation with him in order to drop his guard. Nail then turns around and blasts Frieza with the Mystic Flasher, but unfortunately, the blast has little effect.
Appearances in games
Mystic Flasher was named in Dragon Ball Z: Budokai Tenkaichi 3, where it appears as Nail's Ultimate Blast, also accompanied with a rush: Nail first knees his opponent into the air, then he punches his opponent three times in the face, followed by a Double Axe Handle, then the opponent crashes down to the ground, quickly followed by Nail's devastating beam. The attack is named Mystic Crasher (ミスティッククラッシャー) in Dragon Ball: Raging Blast 2 and Assault Flash (アサルトフラッシュ) in Dragon Ball Heroes. The attack returns in Dragon Ball Z: Ultimate Tenkaichi, despite Nail not being in the game; the attack can be used as an ultimate attack for the Heavy build Saiyan Hero.
In Dragon Ball Xenoverse 2 it appears under the name Mystic Flash and is one of Nail's Ultimate Skills, though it is only the turn-around blast, leaving it to be a tricky Ultimate Skill to land, however it is perfect for dealing with enemy attacks from the rear. It can be obtained by the Future Warrior (Xenoverse 2) as a reward in Parallel Quest 20: "Frieza! Show Yourself!!".
