Ruber

"One day, that sword will be in my hand, and all will be MINE!"

- Baron Ruber, seeking to steal the Excalibur blade and threatens to take over the kingdom of Camelot.

Baron Ruber (simply known as Ruber) is the main antagonist of Warner Brothers' 1998 animated feature film, Quest for Camelot. He is Kayley's arch-nemesis and is a traitorous and evil former knight of the Round Table and is exceptionally cunning, selfish, cruel, greedy, ruthless, conceited, persuasive, egotistical, manipulative, power-hungry, dictatorial, oppressive, mysterious, sinister, brutal, insane, and exceptionally strong, so he is able to kill a dragon with nothing but his bare hands, and sought to gain ultimate power by taking over Camelot (and possibly the world) as well as avenge his previous defeat at the hands of none other than King Arthur himself. He also has his pet griffin, and his metal henchmen.

He was voiced by the legendary British actor, Gary Oldman, who would later go on to portray General Grawl, Lord Shen, and Dreyfus.

History
Ruber was once a trusted and dependable knight of King Arthur and a member of the Knights of the Round Table. However, following the ten-year rule under Arthur's wise hand, Ruber grew obsessive for power and riches, which led the other knights to distrust him. During a meeting in the beginning of the film, Ruber attempts to take advantage of his ranks by desiring riches, to which Arthur refuses to allow. Ruber then suggests that he nominated himself for the throne of Camelot, which one of Arthur's loyal knights, Sir Lionel, berates him by responding, "I will not serve a false king.". This finally drove Ruber into a murderous rage by bringing out a mace, attempting to kill Arthur. Eventually, Lionel ends up taking a fatal blow before Arthur uses Excalibur to finally beat Ruber down on his knees. Ruber then flees away from Camelot, vowing to get revenge by claiming Excalibur and all of Camelot to himself.

Following his ten years in exile, Ruber gather a swarm of barbaric followers to support him in his cause. As the tenth year passed by, Ruber concocts an evil plan to steal Excalibur and using land wagons to infiltrate into Camelot. As a start he had his pet griffin to steal Excalibur from Arthur's castle, though the theft was bungled and the sword ended up being lost in the Forbidden Forest (thanks to Ayden, the pet silver-winged falcon of Arthur's wizard adviser Merlin).

Ruber and his men then attack the lands of Lionel's wife Lady Juliana to get hold of her wagons, and blackmailed her into following along by threatening to kill her daughter Kayley (the main protagonist of the film). During the destructive ransacking of Lady Juliana's village, Ruber uses a potion (which is labeled to have come from ACME) to transform his followers into strong iron golems. However, learning about Excalibur's current location from his griffin and seeing Kayley escape into the Forbidden Forest, Ruber orders the Griffin and several of his men to follow her.

During much of the film, Ruber and his posse chase Kayley (who is now assisted by Ayden, a blind hermit named Garrett, and a two-headed dragon named Devon and Cornwall), only to fall some trouble with the forest's natural inhabitants (at one time, Ruber was able to punch out and kill a large fire breathing dragon with his bare hands before having it roasted for himself and his men to feed on).

During the course of the film, Kayley finally manages to find Excalibur and prepare to head to Camelot, but unfortunately, Ruber and his men have cleared from the Forbidden Forest and captured her. Finally with the mighty sword in his hands, Ruber uses his magic ACME potion to fuse the sword to his right hand, replacing his whole right arm to that of a mechanical version to hold the sword.

Ruber then continues on with his evil plan, forcing Juliana to drive her wagons (filled with Ruber's men inside) into Camelot. Ruber then leads his attack into the castle while several of his men hold down the fort against Arthur's soldiers. Fortunately, Ayden, Garrett, Devon, and Cornvall arrive to aid the heroes. While Ayden, Devon, and Cornwall manage to deal against the Griffin, Kayley and Garrett infiltrate into the Round Table, where they spot Ruber trying to attack a beaten Arthur (whose arm has been struck thanks to the Griffin's attack during the sword theft).

Upon hearing Ruber's gloating of his murder of Lionel, Kayley, swearing never to serve a false king, spots a wooden beam and slams it towards Ruber, launching themselves out from the castle. Garrett attempt to strike Ruber with his staff, but Ruber anticipates this and cuts the staff before throwing Garrett over to Kayley. However, he is unaware that the two are standing next to the stone where Arthur once wielded Excalibur before he became king.

"Oh no! The Stone."

- Baron Ruber's last words

As Ruber closes in for the kill, the two dodge away from the strike, and the sword ends up jammed into the stone, whose power kicks in and starts to expunge the taint of his ACME potion from the sword. As a result, the magic was a sign that Ruber was too dangerous to be kept alive, the spell is broken, and all of Ruber's soldiers transform back into their original human forms, allowing Arthur's knights to arrest them. Around the same time, Ruber is caught in the crossfire between the energies of the stone's power and the ACME potion, and is finally disintegrated to his death, being destroyed by the very same power that he planned to obtain.

Trivia

 * Ruber is loosely based on the Red Knight from the novel that inspired the movie "The King's Damosel" (in turn an adaptation of a character already made a staple antagonist in Arthurian literature). Unlike Ruber, The Red Knight is a less prominent antagonist in the story, though still the instigator of the main plot. He is also nowhere near as affable.
 * He is very similar to Shan Yu from Disney's Mulan (another animated film that also came out in 1998).
 * Both have the same hairstyle.
 * Both have murderous teams of only men.
 * Both have avian creatures as pets (Hayabusa and the Griffin), who were burned out by comic relief dragons (Mushu, Devon and Cornwall) and are sent to retrieve a sword.
 * Both attempted to kill the female protagonists (Mulan and Kayley) with swords, but failed.
 * They both met their explosive deaths at the end - fireworks for Shan Yu and the stone for Ruber.
 * Both have been dubbed by Italian voice actor, Massimo Corvo, who also voiced Peg Leg Pete, Jafar, Steele, and others.
 * However, whereas Shan Yu does not hail from China, Ruber was originally a member of the Round Table.
 * Ruber's voice actor, Gary Oldman also did other villains such as Lord Shen (Kung Fu Panda 2), and the main villains in both Lost in Space and in The Fifth Element, all of which Gary Oldman played as a power-hungry coward.
 * Ruber laughs in agony while being destroyed by the stone.
 * He is similarly designed as Drake from Don Bluth's 1995 animated film, The Pebble and the Penguin, in which both have a strong physiques, and both are made for power, and don't consider their adversaries as a major threat, such as Drake considers Hubie as a "Stupid pa pa pa penguin", and Ruber considers Kayley as a "Little Girl", Garrett a "Blind man", and the Falcon a "Pigeon".
 * He is also very similar to Scar from Disney's 1994 animated film, The Lion King.
 * Both want to rule the kingdom.
 * Both kill the main protagonist's father (Ruber to Sir Lionel, Scar to Mufasa).
 * Both sing a evil song by explaining their plan.
 * Both have henchmen (Scar to Hyenas, Ruber to Griffin).
 * Both reveals that they're the one who kill the main protagonist's father long time ago. which it made the main protagonist angry and fight them by average their father's death.
