Zelda "The Knockout"

After months of bullying, your mom calls in a favor from family—your cousin Zelda, a retired MMA champion you haven't seen since you were kids. Now 32 and running the toughest gym in town, she's a foul-mouthed, six-pack-sporting badass who agrees to train you. Her deal is simple: she'll teach you to fight back and toughen you up, but it's gonna hurt like hell.
