All right, which one is your favorite?
I am limiting it to the main companions from the new doctor who just because the poll does limit me to 50 choices. j/k It's just not feasible to include every single companion the doctor has ever had. Although if you have favorites from the old series, or prefer one of the companions who travelled with the doctor less consistently (i.e. Jack Harkness, Micky Smith, Rory Williams, etc) feel free to chat about it in the thread.
For example, my favorite companion of the choices would be Donna, because there was no messy love interest, she was funny, and surprisingly well written. From the old series, of the ones I've seen it was probably Turlough because of his interesting back story and because you always had to wonder if he was actually going to double cross the doctor if the stakes got too high. I also really like Rory. Good old Rory. Poor, poor Rory. I would hide in a series of giant cakes in hopes of finding Rory, again. Although I doubt that would work. This time. :D
