Ruber

Sir Ruber, also known as Lord Ruber or simply Ruber for short, is the main antagonist of Warner Brothers' 1998 animated feature film Quest for Camelot, which is based on the 1976 fantasy novel The King's Damosel by the late Vera Chapman. He’s a traitorous and wicked former knight of the Round Table, who sought to gain ultimate power by taking over Camelot (and possibly the world) as well as avenging his previous defeat at the hands of none other than King Arthur himself. He also has his pet griffin as his enforcer, and his mutated mechanical barbarians for his cause. He is Kayley and Garrett's arch-enemy.

He is voiced by Gary Oldman, who also played Lord Shen in Kung Fu Panda 2.
