Bad Byron

 was one of the Byron Reprises in Europa. He called himself Albé, lived in the Villa Diodati and indulged his sadistic side. Dangerous Byron challenged him to a seance battle for the right to be Europa's only Byron. The Fourth Doctor interrupted the seance, knocking out both Byrons. When they recovered, they fought a more traditional duel with swords, which Dangerous Byron won. On Albé's death, a House of Usher mechanism was activated, causing the entire Villa Diodati to sink under the ground. (PROSE: Managra)
