Centurions were toys of a modular nature. The good guys were led by Ace Mcloud and the bad guys by Dr. Terror. Each figure had holes on the chest, back, and limbs and one would be able to attach various armor/weapons to these holes. The toys were based on a cartoon series of the same name. The catch phrase was "Power Extreme!". I recall a few vehicles that were also available with the same modular capabilities of attaching to the figures.
The two antagonists, Dr. Terror and Hacker, were able to be split in half and combined with each other.
