Origin
The Buggane King was a Buggane who was chosen to be the king of the Buggane. Fairly Obvious. He (?) was chosen after he was the one to place the last brick of the Temple of Man. He also became the guardian of a Holy Dagger on the island.

Humanity
When St.Tristan and St.Trinian brought their army to the Isle of Man, the Buggane King fought against the two of them personally. He tore off the Arms of Trinian and the legs of Tristan, but both were able to flee. He then led the Buggane for the rest of the war before losing all pulling everyone back to the Temple.

Galahad and Charlemagne
When Galahad arrived on the Isle of Man, he took the Buggane King hostage and forced him to create a storm in an attempt to destroy Charlemagne's ship. After that failed, Galahad quickly killed the Buggane King before wiping out the rest of the Buggane.
