Ike is in general considered to be a cheap or uber character.
That made me laugh actually. Terms like "uber" and "cheap" really make me laugh when it comes to SSB games in general. Just seems like an excuse for somone to cry over losing when they're beaten. I see no character as the ultimate, as you can always match it with your own character and skill. I for one know Meta Knight's biggest weakness as a light character; Dedede can make short work of him. Ike has a short attack range (his "long distance" is super predictable and avoidable), characters like Diddy and Samus with projectiles work great.
I've heard almost every character in Brawl be called "cheap", and it's always by the guy that just got his *** handed to him because he wasn't good enough.
