Engetsuzan

Engetsuzanzai (三日月の斬首刑 "Crescent Moon Decapitation") is the side special move of Ichigo and his final form, Bankai Ichigo in Super Smash Flash 2. This technique combines the Flash Step technique with a powerful Crescent Moon Slash. Both characters teleport forward and attack. The attack has semi-spike properties. Bankai Ichigo's version of the attack is called the Dark Flash Step which has a larger range and doesn't leave him helpless.

Trivia

 * In the manga/anime, this technique was first used by Byakuya Kuchiki to kill Ichigo.
