I agree that Franky's personality is too strong (that's even what I said in some other topic). But he has had a tragic event in his life (being almost killed and becoming a cyborg) which would almost in itself qualify him for the mugiwaras. Maybe Pauly has had a tragic childhood which would bring him above Franky, we'll just have to wait and see after next episodes flashback.

Join the dark side. Watch the subs from Hell... and Xelo and some from Balf.
