Leap-Frog is the name of two fictional supervillains appearing in American comic books published by Marvel Comics. The characters use a frog suit containing electrical coils on the soles of each of the two flippers which allow the wearer to leap great distances up to high or long. The boots' power source is worn on his back like a back pack, and triggered via hidden buttons in his gloves. Additionally, the costume later had a strength-boosting exoskeleton along with substantial internal padding and a computer-guided system for leaping accuracy.
