Zokalo is a harsh man who wears a hard leather (almost metal-like) mask over his head. Unlike the other generals, he seems to have little regard for his Exorcist team (consisting of Kazana Reed, Chakar Rabon, and Suman Dark, all of whom are eventually killed by Tyki Mikk).
Zokalo first appears alongside Cloud Nyne before the coffins of their respective team members. While Cloud Nyne weeps, Zokalo insults his team, calling them “a bunch of losers”. Whether this was really out of disrespect, or a form of denial and/or grief is unknown. It could also be taken as a metaphor. Later, when the Level 4 Akuma attacks the Black Order headquarters, he counterattacks with his fellow generals. He viciously rips apart several Akuma and revels in the bloodbath that they spawn.
Zokalo’s innocence is called Madness ( ??? , Madness) and is an Equipment-type Innocence. When not invoked, it appears as two spiked half-rings attached to Zokalo’s shoulders. When Zokalo invokes his Innocence, he slides the rings down his arms and claps his hands together, creating a complete circle. When the circle is complete, two enormous blades materialize on either side of the ring. Zokalo uses Madness as a powerful, close-combat Anti-Akuma weapon, usually by spinning the blades at high speed, creating a massive buzz saw. He can also use his Innocence in an attack technique, called Madness Dederupa ( ??? ??? , lit. Cremation Dance), in which he spins the blades at a very high speed (causing them to be superheated) and throws them at his enemies, melting and slicing them. He relishes the fight and displays extreme bloodlust during battle.
In a Volume 15 omake, it’s revealed he was a prisoner before joining the order.
