Axe Cop began when Ethan visited his family for the holidays and found himself illustrating the madcap adventures of his little brother's imaginary hero "Axe Cop" -- basically a cop with an axe who has the power to behead, poison, explode and chop up his many enemies, often with the assistance of a super-team of shape-shifting giant babies, giant avocadoes, giant dinosaurs, giant robots, ninjas (including a pair of Vampire Ninja Werewolf Wizards From the Moon!) and so on and on, each superlative attracting another until they are daisy-chained into a synthetic molecule of pure, superdense awesome.
Axe Cop became an Internet sensation, and sold enough merch to keep young Malachi in toy guns and action figures for quite some time, and it was only a matter of time until the book came out. Getting all your Axe Cop between covers in one concentrated blast is quite an experience, but in a very good way! Ethan's notes about Malachi's creative process and their extraordinary collaboration really help to frame the strips, and the best stuff of all are the reprinted Ask Axe Cop, in which Malachi fields questions from the Internet at large.
There are plenty of comics artists who've tried to recreate the unbridled exuberance of a hyperactive kid's imagination, but this is the real deal. As Graham Linehan says in his cover-quote: "Axe Cop is actually a time machine. Through its pages, we can return to that state of intensely excited, unbound imagination-overload that we all shared as children, and lost bit-by-bit as the years progressed. Read Axe Cop, and you will remember the kid you once were."
