Forum:What counts as an enemy?

What counts as an enemy of an incarnation of the Doctor? The Draconians, Slitheen etc. were listed as part of the Alliance, who were enemies of the Doctor, yet are not part of the Eleventh Doctor enemies. Should they be? I personally think so, as even without an appearance, they are mentioned to be. Opinions? The Thirteenth Doctor 12:33, July 7, 2010 (UTC)
