Villain Overview

This world is about to see the reign of Clavius.
~ Clavius

Sir Clavius, also known as Clavius for short, is an evil magician and the main antagonist of the 1997 animated fantasy film sequel The Swan Princess II: Escape from Castle Mountain.

He was voiced by Jake Williamson, and his singing voice was provided by Michael Lanning. However, Williamson does his lines in the "No Fear" rap over the end credits.


Sirs Clavius and Rothbart (who was his former friend and partner in crime) conquered the Forbidden Arts together, but Sir Rothbart took all of the power for himself and drove Clavius underground.

Living in Castle Mountain, Clavius planned to kill Prince Derek, the one who killed Rothbart and took his castle at Swan Lake, so that he could enter his castle and get the Forbidden Arts, which was a crystal ball containing magical powers - the power to create, change, and destroy. His servant Sir Knuckles set some traps for Derek, but he overcame them all.

Clavius disguised as a clown on a balloon aircraft.

So Clavius disguised as a clown riding his balloon, kidnapped Derek's mother, Queen Uberta, and held her hostage in his lair, so Derek would come to him. Knuckles set more traps for Derek, from which he was rescued by Princess Odette, who had Bridget turn her into a swan.

King Clavius

Clavius was able to get the Forbidden Arts and absorb its power. Derek fought Clavius, who gained the advantage by his magical powers, but Jean-Bob jumped on him to distract him at the last second where he was about to kill Derek, and Clavius killed him (from which he was revived by moonlight on the lake at the end of the film).

Then, Derek grabbed the orb, which would explode if it fell to the ground or if blasted by the power to destroy. As he and the others made their escape in Clavius's hot air balloon, Sir Clavius jumped onto it and tried to attack Derek and take the orb back, but Derek knocked him over the edge onto the dock, accidentally sending the orb falling as well. When the orb hit the ground, it exploded and caused the mountain - really a dormant volcano - to erupt. Everyone was able to escape, except Clavius, who had no means of escape and was consumed by the molten magma and magic explosion.

He is briefly referenced in The Swan Princess: The Mystery of the Enchanted Treasure, when Derek says he and Rogers found Rothbart's underground chamber "after Clavius and the orb were destroyed".

Powers and Abilities

Sir Clavius obtains the magic of the Forbidden Arts

"King" Clavius demonstrates his new-found magic powers.

When Clavius obtained the powers of the Forbidden Arts at last, he has finally become a real sorcerer and was given access to numorous magical abilities through the very three acts of the Forbidden Arts: the power to create, the power to change and the power to destroy. This makes Clavius a very dangerous man.

Clavius changes clothes easily with his newfound wizardry by changing quickyly or simply zapping swirling, magical bolts at a person's clothes and make them his own clothing to wear.

Clavius plays with a magic rock guitar

Clavius plays with a magic piano

Clavius can create all sorts of instruments (musical or others) made of magical energy such as a electric guitar and a piano however and whenever he likes.

A Portrait of King Clavius.

A bewitched sword conjured by Clavius' magic.

He can also create and materialize things and weapons out of nothingness such as bewitched swords he can control at will or a seemingly regal chalice-like cup to drink at his enjoyment, a portrait painting of himself as a crowned king or even a mass wealth of gold and jewels to stay rich forever.

Joyful Clavius

Clavius' treasure

He can also turn anything he touches like he did with somewhat huge stone steps and rocks in his lair into gold.

Sir Clavius with his wizardry due to the awesome power of the Forbidden Arts, can change anything from a mere furniture such as a chair or a stool into a throne to fit with his new lifestyle, wealth and power.

Clavius can turn anything and anyone to any form he chooses like he did with transforming Queen Uberta into a variety of animals while she was annoying him, and with turning Jean-Bob into a human prince for a limited time.

At last but not least, Clavius can also finally injure or kill someone and any living thing with the ability to destroy, which makes him a dangerous enemy.
