Yoriichi Type Zero's appearance largely resembles Yoriichi Tsugikuni, the person it was modelled after. It has six arms and hands that each hold a katana, due to the fact that two arms weren't enough to completely replicate Tsugikuni's movements. It is also shown to be heavily damaged, with half of its face and one of its arms missing.
Abilities and Powers
Yoriichi Type Zero has 108 different movements based off of the person it was modelled after. Its power surpasses most humans, which is why it is used as a training dummy for Demon Slayers.
