Doctor Who: 10 Characters Who Should Have Been Companions
We all love (well, most of the time) the Doctor Who companions that we've had over the years, but somehow we still pine for the companions that could have been. Characters that showed up for a single episode and were so well-suited for the show you could easily imagine them travelling with the Doctor for years. Sometimes we just want something a little different -- a male companion, a historical companion, an alien companion. Maybe the timing wasn't right. Maybe the TARDIS already had a companion or two (or three, in the Fifth Doctor's case), and it would have been too much to take on another. Maybe the writers simply didn't know a good thing when they had it. For whatever reason, it's hard to watch these fantastic characters and not wish that they could have had a shot at the big leagues. These are the best of the also-rans.
