Engetsuzan

Engetsuzan is the side special move of  and his final form, Bankai Ichigo in Super Smash Flash 2. This move is a combination of Shunpō and a Crescent Moon Slash. Ichigo and his Bankai form either flash step (running extremely fast and leaving afterimages due to the speed) or teleport forward when the attack is executed, respectively.

Ichigo attacks in two segments - when an opponent is caught in his path, he uses the momentum of his running force to hit the opponent with the pummel of his sword when he raises it to slash, knocking them back and dealing a small amount of damage plus hitstun. Then he slashes them backwards, dealing much more damage and knockback. But this is the biggest weakness of normal Ichigo's Engetsuzan. Because he uses his own body to first hit, and then slash, a melee or ranged attack with higher priority can easily counter his. Bankai Ichigo does not pummel the opponent and simply does a powerful slash with his sword, and so has very little to no problems with being countered.

Bankai Ichigo's version of the attack is called the Yami Shunpō, which is slightly faster and does not leave him helpless when used in midair but has a very shorter range and cannot be charged. However, due to the fact that Bankai Ichigo teleports during his charge instead of flash running, he disappears out of sight and his attack cannot be interrupted or countered when he is charging.

In v0.9, the distance can be charged, but he will continue to fall at normal speeds, so it is not too practical in combat. Ichigo will stop and slash an opponent if they get in his path during the movement and fall into helpless mode, so it is not as good for recovering as it used to be. In v0.9b, Ichigo slashes through opponents instead of slashing at them and losing momentum making the move a better recovery option.

Trivia

 * In the manga and anime, this technique was first used by Byakuya Kuchiki to destroy Ichigo's Shinigami power.
 * On the Smash Flash DOJO!!!, this move is called "Shunpō". This is not correct as Shunpō by itself is not a means of attack, but rather the act of moving at very fast speeds.
