Sir Ruber is an evil knight who was the main villain in Winnie the Pooh and the Quest for Camelot. He plotted to steal the throne of Camelot and plunder it of all of its riches with the aid of a gryphon, several demonic goons, and the stolen sword, Excaliber. Even Darla Dimple arrive to help him out, in exchange for revenge on Pooh and friends. Unfortunately (for them), they were both vaporized by Excaliber's pure light when the sword was plunged back into the sword in the stone.
