Mars Attacks the Transformers

In this 2013 IDW one-shot, writer Shane McCarthy and artist Matt Frank orchestrate a chaotic crossover where the mechanized Autobots and Decepticons find themselves on the receiving end of a Martian invasion. The Martians' ray guns prove surprisingly effective against Cybertronian armor, forcing the warring factions into an uneasy alliance against a common, green-skinned foe. This single-issue story is a fun, standalone clash of two iconic franchises, capturing the absurdist thrill of seeing classic Transformers characters zapped and probed.
