Jumping on that 90s revival bandwagon, or something.
I severely doubt EXTREME DINOSAURS has any chance in hell of coming back, which is a shame since the Raptor trio were a lot of fun (and I think the ONLY time dromeosaurs were used as major villains outside of Jurassic Park, which is utter madness).
Haxx - the dumb one, or at least the one who gets bossed around the most. He's oddly enough the most competent with his weapons (damning with faint praise, but...). Haxx has a bit of a soft spot, once releasing a hostage so that Santa would give him a pet tarantula.
Bad Rap - the leader with a real nasty attitude. He inadvertently caused the K-T Extinction Event with that arm cannon of his (which naturally had to be immediately written out of the show, heh), and now plots to cause global warming and bring back Velociraptor-kind... somehow. They have to be EVIL raptors, though -- he literally came across a dinosaur paradise once and had to go and ruin it because the local raptors wished him a nice day.
Spittor - the "brains" of the group... although he's kind of a doof, too. He's at least good with machines. As the name implies he spits on his enemies (hey, a dino besides a frilled Dilophosaur using that gimmick!), but the Extreme Dinosaurs always find a way to use it against him.
Spittor is a fan of modern art!
