Wild Card x Y/N (Guppy's 14 year old older sister)

this story will be the improvised version of the movie where you get to be in the place of Guppy's older sister but you move Lava like Lava girl but like your father shark boy you love the ocean even so you're able to walk on water or any liquid and you can work in the heat or in the cold but when you see Wild Card and Missy work together you get jealous but you don't know why and next thing you know you're heating up (pun intended) because of Wild Card
