Avenging Wallflower. These players play characters with a vast amount of unheralded, unseen power and go out of their way to be meek and unassuming, at least until a dramatic confrontation occurs in their vicinity. Whenever active, outgoing characters do something interesting near them, they will feel an unholy compulsion to leap into action, screaming and blowing things up with their incredible
powers, simply to interfere in the process and thereby feel that they've done something. It's quite common in Anime, and I've seen about a thousand 'I'm a dragon ploymorphed into a halfling'.
