did Knuckle remind anyone else of Yusuke from YYH? same face, same manners, only gazzilion times cooler.
I liked the way he drops down Shoot, and Shoots says 'what the hell' and then understands and tells him to give Yupi a beating...

also, I predict a three man form for the fighat against Yupi - Killua, Meleroon and Knuckle.
Killua uses his uber counterpunch to protect Kncuckle, and Knuckle delievers some uber punches to beat up Yupi...
