Ichigo has a whole bunch of attacks including Tensa Zangetsu V2, Final Getsuga tenshou and vasto lorde hollow.

his final smash is Tensa Zangetsu V2, he becomes stronger and gains new moves. There's a counter on the mode when the counter is over, his attacks become normal but he still remains only faster. If you die in this mode, you come back as Tensa Zangetsu V2.

However If you die before the counter is up in Tensa Zangetsu V2, you start from normal Ichigo.

When in Tensa Zangetsu V2 mode, his final smash is Mugetsu.

When his HP is over 100%, his final smash is vasto lorde hollow that you can move left and right.

When his hp is over 60%, use the up taunt to activate his hollow mask.
