Haxx is a mahogany-colored Raptor with implants on the backs of each wrist that produce green blades. He is set back by his low intelligence. Terrified of bees. He loathes the Extreme Dinosaurs because they keep thwarting his group's plans to destroy humanity. He has a somewhat playful side as well. Haxx has a sensitive side on multiple occasions, such as risking his own safety to return a child that he and his group kidnapped back to the Extreme Dinosaurs. He only wears pink shorts.
