Cultural references to the Doctor Who universe

Conversely to crossover characters appearing in other fictional universes, elements of the Doctor Who Universe have (for the most part, unofficially), occured in other continuities.

Comics examples

 * [Wikipedia:Marvel Comics|Marvel USA]] occasionally made oblique references to Doctor Who - the X-Men spin-off Excalibur featured the Weird Happenings Organisation, led by Brigadier Alistaire Stewart, a female counterpart of the Brigadier.)


 * The 2000AD strip Caballistics, Inc., which features Doctor Who references so frequently they are practically part of the series' format, once depicted a character clearly intended to be the actor Tom Baker being murdered by Scottish nationalist demons. This would undermine the frequent suggestion by Caballistics, Inc fans that the series is unofficially set in the Doctor Who universe.
