Bad Rap is the leader of a group of Velociraptors (or Raptors). They are enemies of the Extreme Dinosaurs.
Bad Rap was once a normal raptor until he and two other raptors were abducted by Argor Zardok's spaceship, after Argor turned down his other experiments, where three raptors were mutated into humanoid forms. As Argor was pleased with his experiments, he gave a weapon to Bad Rap that was an arm cannon equipped on one hand that can dissolve solid matter effortlessly. Argor then sent the three Raptors to deal with the Extreme Dinosaurs. However, as they fought, they weapons they were using were proven to be too much for the Earth's environment to handle, causing it to wipe out the dinosaurs. As Bad Rap and the raptors sees Argor leave on his ship, they say he betrayed them and fell asleep in pods until the present day, along with the Extreme Dinosaurs who were unaware of it.
And he is reprised by Garry Chalk in the English dub and will be voiced by Banjo Ginga in the Japanese dub.
