The Adventure of the Redheaded League! With just a few fan favourite of the Doctor's copper-haired companions, this potential on screen meeting would make for some hilarious moments. The observation that the Doctor tends to favour redheads has been made several times on screen and this meeting would really ram this point home. Naturally, there would be sparks as the four tried to subtly compete for the title of 'The Ultimate Ginge' and this could make for some really interesting group dynamics along the way. It'd also be entertaining to watch the Doctor's attempts to cope with four hotheaded companions all being in the same place at the same time. Rather him than us... What did you think of this list? Are there any other Doctor Who companions, past and/or present, that should meet on screen? Share your suggestions in the comments section below!
