Lash is one of the two secondary antagonists in Sky High. He is one of the school's bullies, and later an ally of Royal Pain.
Elasticity: Lash has the power to extend and contract his body and its parts to great lengths. He was able to use his elasticity to convert himself into the equivalent of a giant slingshot. Lash likes to use his ability to stir up trouble, such as tripping Will Stronghold in the cafeteria to provoke a fight with Warren Peace, ups a cup of ginger ale at the Homecoming dance, and snatches Ron Wilson's cap.
