Transformers

Note that the Transformers actually exist in an alternate universe, as established in The Incomplete Death's Head #1. Death's Head was a Marvel UK character, who spent some time with the Transformers before he was teleported around by the Doctor from Doctor Who, in Doctor Who Magazine #135. So now it all makes sense.
