Leapfrog was an ex-designer for novelty collectibles, and for vague and nonsensical reasons, quit his day job to become the nefarious Leapfrog! Using his knowledge of novelty memorabilia, he created an extremely durable frog costume that grants him many abilities, such as spring loaded feet that let him jump high. Leapfrog has stood his ground against some of Marvel’s top heroes, some of which were Daredevil, Iron Man, Spider-Man, and even Wolverine!

Also, in some comics he’s a transformer. Little known fact!
