"If Charlie were a villain she'd be so serious and scary and intimidating-" No she wouldn't. Charlie as a villain would be even GOOFIER. Because Charlie would absolutely go ALL IN on that shit.
She'd immediately replace her outfit with a black and red version (not red and black like her current attire but black and red, because the more black makes it look more eeevil) except exchange the bow tie for a necktie (because neckties look evil) and replace her suit with a kind of long jacket with a bottom that flares dramatically when she moves around. She'd have a black staff topped with a gold music note that she used to bop enemies on the head or doubles as a microphone like Alastors. Her minions would literally just be Razzle and Dazzle but with sharper teeth, darker colored, more messy fur and potentially tiny mustaches as they go around knocking over people's drinks or pantsing them. ANY time someone asks who she is or what her evil plan is, she immediately breaks into a musical number. Every fight for her, she considere a performance where she dances around her opponents, shows off how powerful she is, and does stuff like mess with their hair, spanks their asses, and drums on their heads while she sings about how lame they are compared to her. She would put her enemies into elaborate death traps and just make sure to stay, watch, and have some snacks while they die painfully. If she wanted to pick a fight someone or mock them, she'd pull one step up on Alister and hijack EVERY TV in Hell just to call her enemy a bitch.
Charlie as a villain would be the goofiest, most dramatic bitch in Hell because Charlie would 100% lean into being "The Bad Guy."
