Non Disney Villains Tournament
Revived by Dolf and Blackwolf, Sharptooth sets off to destroy Doctor Robotnik and Snively. He tries to find them, as they manage to camouflage themselves in some thorns. Before he can react, the two scientists blast him with a laser. Only stunned, Sharptooth lashes out at his foes, losing an eye in the thorn patch. Robotnik sends SWAT Bots after the T. Rex, but Sharptooth sends them falling into the river. Snively then hits Sharptooth with a cannonball. Sharptooth gets up just in time to see Robotnik set off a full battery of cannons, blasting Sharptooth down into a gorge.
