Engetsuzan

Shunpō (瞬歩, "Flash Step") is the side special move of Ichigo and his final form, Bankai Ichigo in Super Smash Flash 2. Both characters teleport forward and attack with a powerful slash. The attack has semi-spike properties. Bankai Ichigo's version of the attack is called the Yami Shunpō (闇瞬歩, "Dark Flash Step") which is slightly faster, suprisingly has a shorter range and doesn't leave him helpless when used in mid-air.

Trivia

 * In the manga/anime, this technique was first used by Byakuya Kuchiki to destroy Ichigo's Shinigami power.
 * This variation of the Flash Step is actually a special attack called Engetsuzanzai (三日月の斬首刑 "Crescent Moon Decapitation"), but the name was simplified to Shunpō for this game.
 * On the Smash Flash DOJO!!, this move is incorrectly romanized as "Shunpo".
