He is a strong man with huge muscles from facing dinosaurs and completing other labor. Rax lives with dinosaurs and his walking body of scars is proof. Some believe he is a hairy monster, but his fellow companions believe he's their leader. Everything he wears came from his hardwork. He cut the tail off a dead Euoplocephalus and made it into a hammer, took spikes off a Stegosaurus’ back and used them with bones to make a piece of armor running down his back, and tore the horns off a dying Triceratops’ head for a helmet. In fact, he made his helmet to resemble a Triceratops’ head.
Living with dinosaurs, he had to be strong, and if not, he had to be smart. Raxasaurus (a.k.a Rax) was intelligent, but he wasn’t strong. When facing dinosaurs such as a Triceratops or Tyrannosaurus Rex, he used his brain. Did he win every time? No, not until he understood his environment was his key to winning, and once he did, he began to conqueror T-Rexes, Brontosaurus, Triceratops, Etcetera, and devour their flesh. Then one night, he ventured deeper in his cave, finding Saurous’ powersource and touching it via curiosity. His hands would cause sparks to fly and he would scream in pain as his armor was fused into his skin and he gained super strength.
