Haxx is one of two Raptor underlings of the evil Bad Rap. He has implants on the back of his wrists that can generate green blades and his tail is replaced with a blade-covered mechanical tail that can spin like a drill. He is the most gifted of his group, but his only setback is his low intelligence. Unlike Bad Rap, he wasn't trapped in the Andes mountains when the Dino Vengers first pursued them.
- Unlike his more dimwitted counterpart on Extreme Dinosaurs, the Street Sharks version of Haxx is sinister and an actual viable threat to both Dino Vengers and Sharks.
- Haxx is the only Raptor whose counterpart on Extreme Dinosaurs is of the same color scheme as him.
