Bruce is a weapon expert and master soldier who was rejected from the Dinosaurian Army after he was caught practising his attacks on people who bully him. He is uncertain of wether he should be good or evil, but he likes hanging around with Mr Rex and adding Rimshots to Mr Rex's Puns. Bruce also plays several brass instruments such as the French Horn, Trumpet and Trombone all at the same time. Bruce's character besides his killer instinct consists of little violence and a warm hearted yet shy ally who has an ultimate goal of impressing girls. So far no one has liked him back, he will only become aggressive if provoked. He shows his anger by blasting everything around him with a Universal Recycling Energy Aura and Threatening his foes with his Long Claws with a blade that goes so sharp, the tip is only 1 atom diameter.
Bruce first appeared in Spore: Galactic Adventure as a 3rd party member to the player. Bruce's Design has been almost completely Modified to what he looks like now, he used to have Emo-hair, cyborgentic implants and a mustache. His coat colour was also changed to Black to make him look more threatening.
