Orthotron

Orthotrons were a race of humanoid robots. Two Orthotrons, Boris and Elsa, competed in the Universal Dance/Off (nine million and two) in 2009, but lost out in the final round to the Shivashian dancers Durrrin and Laliaargh. When the Orthotrons found out that the competition's adjudicator had fixed the results in favour of the Shivashians they began shooting in the Cosmos Ballroom. According to the Tenth Doctor, this was the trigger for Space War III. (COMIC: Death Disco)
