There's one thing that annoyes me with Kisame- we all know he won't be a badass.
there's no going around that, as much as I like to think of him as Zabuza #2 (Zabuza is one of the best anime villans, me thinks), it seems that he's just a stupid goon who followes Itachi and won't stand a chance against any 'half cool' jounin, he falls into the class of arrogant muscular buffons, like most of Inuyasha's 3 episode enemies, or the guy from Kenshin's first episode.. all brawns and no brains...
it's a really annoying trait of animes, pretty boys are allways stronger than strong looking guys, think about it, the guy with the thin curved sword and the long hair will allways beat the heavy wheight champion which uses a broad sword...
and not only that, Kisame has yet to speak one word of 'intelect' yet, all he said was how much his sword is great and how awsome he is, and when a bad guy speaks like that, we know he's just bark and no bite.
Too bad, Kisame could have taken a good spot in the badass list, now he's just Itachi's side kick... destined to be beaten by the likes of Sakura and the girl team..
Edit: I know that Berserk isn't like this, but it's an exceptional, so mighty and great as the manga\anime is, it's not part of the discussion.
