Gangrenous Frogpenis

The hero of a comic in which a frog with a humble job as a shit scooper at a local vet's, comes in contact with radioactive feces and gets gangrene on his dick. He also gets superpowers such as the ability to mold said phallus into anything from a blunt death club to a functional LAAG antiaircraft gun, just liek the one in Halo, complete with seminal ammunition. But he only has three days with which to use his distorted tool to save the entire world from a messy death by the Concordia people.
