The Ukomo Avalanchers are an alien race of sentient dinosaurs (the Teratons) introduced in Season 3 expansion for DreadBall.
Armored hides make Teratons tough customers to begin with. Couple that with their in-borne defensive ability to teleport when attacked from behind or to move through obstacles as necessary and you can see why they're a popular team. Playing them takes finesse, though, as they field no strikers and are comparably slow against many other teams---even if they can teleport a limited distance.
The basic team includes 8 models:
4 Teraton Jacks
4 Teraton Guards
From the DreadBall Sports Network: "The Avalanchers haven’t been around for long, but their hard-hitting play style has already won them plenty of fans. The fact that they’re giant teleporting reptiles doesn’t hurt, either!"
