Itachi could very easily become the bad guy, just his motives aren't as destructive as Oro's.

But man, Oro has Kabuto wrapped around his finger, I wonder what he did to cause that. Well...he does have that tounge....

But still, I want to know WHY Kabuto is so strong, wouldn't it be interesting if he has some advanced Curse Seal?

But the Kimmaro(sp?) I'm thinking that its just the name of the competition.
