The one who laughs last

Two siblings are kidnapped from the streets by descendants of an old dual-nature experiment. Jasmine develops powers that amplify who she already is, while Cage appears normal until a far stronger second personality, Last Laugh, emerges: turning damage into power, with enhanced strength, speed, and reflexes. Whoever triggers Last Laugh hears one final laugh before they die. Cage’s normal self has only half that strength, making the transformation terrifying.
