Axe Cop is the hit webcomic written by Malachai Nicolle (age 5) and drawn by his brother Ethan (age 29).
Take down Dr. Stinky Head and all his criminal mates, until you gain enough rep that they won't dare come back. (Which just so happens to be when you reach level 10!)
Munchkin Axe Cop is a stand-alone card game designed by Steve Jackson and illustrated by Ethan Nicolle. It is sort-of compatible with the original Munchkin.
