In 2012 Headrobots created a Fortress Maximus homage named Centurion. He is a set of two replacement heads for Spike.
The US version of the head is very similar to a "garage kit" Spike head made in 2007 by Hal Zucati.
Headrobots first teased Centurion on the internet in January of 2012.
In Undercover!! The Great Drone Counteroffensive Courageous steals a mysterious disc from the evil Headrobots. He uses its powerful algorithm to create Drone from the source codes of himself, Stronghold, Centurion and Hothead.
