Doctor Who: The Curse of Fatal Death/Characters

Alternate Ninth through Twelfth Doctors (Rowan Atkinson, Richard E Grant, Jim Broadbent and Hugh Grant)
From the Comic Relief charity skit The Curse of Fatal Death. A parody, not even remotely canon. Written by Steven Moffat, who lovingly references it in episodes on occasion now that he's actually in charge of Doctor Who.
 * Deadpan Snarker: Atkinson, very much in the mould of the later Blackadders.
 * Official Couple: He and his companion, Emma (Julia Sawalha) are engaged.

In the last segment of the sketch, he regenerated several times, finally ending up as:

Thirteenth Doctor (Joanna Lumley)

 * Bi the Way: She seems equally happy with the thought of marrying either Emma or the Master.
 * Gender Bender
 * Jumping the Gender Barrier: The Master is very taken with the Doctor's new form.
 * Man I Feel Like a Woman: "I've always wanted to get my hands on one of these!"
