Future regeneration of the Doctor? I have this female version, or I can switch to a guy (probably PB of Benedict Cumberbatch). Het, gen, or slash; I'm terrible at femme. My future Doctor is sort of a cross between 10 and 12: goofier than 12, but snarkier than 10.
Up for canon, OC, or crossover companions. Seriously, just toss it at me.
