When in it's first stage, Sakende Shibo transforms into a massive Buster Blade. While swinging this blade Hisoka is able to use his reiatsu as a sort of air slash. Infusing every swing with some of his energy he can launch multiple waves of Reiatsu at once.

By forming his hollow mask and transfering his Zanpaktou into his body, Hisoka becomes a power filled fighting force that uses it's fist as a weapon. While in this form his reiatsu output is massive enough to make captain's nervous,

When in it's final form Sakende Shibo unleashes all of it's power causing Hisoka to undergo his full hollowfication transformation. While in this state Hisoka has control over his judgements unless he decides to let his inner hollow become the user.
