I'd like to see the rogue sneak up and perform atomic wedgies and purple nurples on enemies. Or a special sneak "Kick Me" sign application, that would then result in the enemy being seized upon and kicked to death by all the other kids on the playground.
Sounds awesome: You distract the enemy by pointing and saying, "Hey, look over there!" The enemy turns around and you attach the "Kick Me" sign to their back. As the enemy turns back around to face you, a bunch of little kids come from out of nowhere to start kicking the enemy into submission. (I imagine "cartoony" fight effects -- simply a big cloud with swinging fists and kicking legs sticking out.) After a sufficient beat-down, the little kids runaway and disappear as quickly as they came...
Animators, start designing the gang of little hoodlums!
