Who would YOU Cosplay as?

I would cosplay as Balrog from Cave Story (see avatar). I could even make the costume with posterboard, construction paper and glue! However, I think it would violate size rules for costumes :(

I could get away with going as Mori from Ouran High School Host Club. However, I would only do that if I could convince my short blonde friend to go with me as Hunny. It would only work if we both did it.

I guess I'll have to go as some blocks from the first Super Mario Brothers game.
