"Oh, come on, when have I been irrationally violent? I mean, within the last... um... Half an hour?"
Invoked: Marcy exists in a world populated with Personality Powers and intentionally cultivates her forceful personality to gain access to her superior firepower
Defied: Marcy is an Actual Pacifist and refuses to learn magic meant to hurt people.
Discussed: "Ah — she blew up the dragon. Don't get on her bad side, boys."
Implied: Marcy is a side character who is not shown fighting, but she recalls a Noodle Incident where she blew a dragon up.
Deconstructed: Marcy can destroy towns with little effort, and she has an extremely short temper. She leaves a wake of ruin wherever she goes, and no one has the nuts to call her out. Then, after a particularly bad outburst, she's out of energy when the army of Emperor Evulz attacks.
Reconstructed: Marcy is extremely destructive and short tempered, but her Nakama is always there to remind her to save her powers for the real bad guys.
