Corporal Burt "Nick" Nicholson is a typical representative of the rank and file in Tagon's Toughs: strong, violent, and not terribly bright. Despite this, however, he has proven his worth time and time again, displaying both loyalty and bravery in the face of impossible odds.

When first introduced, Corporal Nicholson was missing two fingers on his left hand. This was later rectified by Lieutenant Edward Bunnigus, who replaced the hand with a freshly cloned appendage.

Following his incapacitation during the Princess Tyola storyline, it was revealed that Nick possessed numerous soldier boosts - metabolic and anatomical modifications that are outlawed in most solar systems.
