Because he's chubby and weird.
He funny, energetic, and has a lot of energy and a style about him that makes me like him a lot. So underrated in my opinion, I find his style of comedy to be much more funnier then most other characters like Dento's(Sorry fangirls), Cabernet's, or Bel's. He also has a great Pokemon in Dageki that has a lot of personality, and is a Martial Artist. He's kinda fat but, buff at the same time which I find relatable. He trains hard and against the elements, and the fact he has his own rival with Masaomi and might very well win the Donamite gets me pumped.
He's better than Morrison, and he is a Winner!
And He's got a SAWK. Can't argue with a Sawk!
