Bankai Ichigo

Bankai Ichigo, also known simply as Bankai, is 's Final Smash in Super Smash Flash 2.

Overview
When performed, Ichigo concentrates his spiritual energy and envelops himself in a dark, massive whirlwind-like explosion that deals 25% damage and high knockback to opponents hit. When it disappears, his Zanpakutō is transformed into Tensa Zangetsu and Ichigo himself is temporarily transformed into his Bankai form. Bankai Ichigo is one of the many Final Forms in the game, which means he is much different from his normal form and has greatly improved attributes, such as more powerful attacks and increased knockback resistance.

As a Final Form, Bankai Ichigo excels in his speed, possessing one of the fastest dashes in the game. Bankai Ichigo also has a floating ability and can midair jump infinitely. This, coupled with his good aerial attacks, makes him a less "slippery" character when it comes to controlling him in the air or jumping. He has two aerials, and forward, that meteor smash and semi-spike opponents without any need of a sweet spot. However, his aerial attacks have a long start-up lag.

Origin
In the Bleach franchise, Bankai is the third and final form of a Zanpakutō. Only the strongest Shinigami can use it, and it is the ultimate technique of a Zanpakutō. To achieve this form, one must be able to materialize and subjugate their Zanpakutō spirit, meaning the wielder needs to summon it into the physical world. It usually takes ten years or more to achieve, plus the experience needed to master it, but Ichigo was able to achieve it in just three days with Joruichi's training. The power and forms of Bankai vary according to the wielder's strength and training, but in general, one's power can grow five to ten times greater by attaining it. Because Ichigo is a very special Shinigami, Bankai power multipliers could be much larger.

Trivia

 * When hit with a flame attack, Bankai Ichigo is completely enveloped in a giant ember instead of just letting off puffs of fire.
 * Prior v0.2a of the SSF2 Demo, Bankai Ichigo used an uncharged form of Kuroi Getsuga as his down special move rather than Multislash.
