A Blacklist Hunter with a twisted reputation—he's hunting criminals while being hunted himself. He's got this weird ability: by chewing on someone's cut hair (specifically hair trimmed with his favorite scissors), he can extract pretty much any information stored in their body. Yeah, it's as gross as it sounds.
He's got a thing for messing with Bisuke, but here's the thing—even after finding out what she's really capable of, he doesn't back down. He actually pushes for a fight, though he tries to level the playing field by insisting they go at it without Nen.
That didn't work out. Bisuke beat him down hard enough that now he's stuck doing training sessions with Gon and Killua, basically as punishment or forced self-improvement. Fans often note the comedic irony of this supposedly tough fighter getting knocked around and having to drill with kids.
