What it says on the tin.

You can choose any character from any form of fiction as a companion for a Doctor.

This could change daily for me, but tonight I go for:

Richard Sharpe - Lieutenant, 95th Rifles.

Doctor - PT.

Frodo Baggins.

What Doc would you put the little fella with?

Sam Tyler - Mindf**k

I'd switch out K9 for Bagpuss. Then, if I was being just a tiny bit more serious, maybe Raskolnikov or Holden Caulfield or one of their line with Hartnell?

Yeah, because "am I mad, in a coma or back in time" is technically a false, ummm, trichotomy.

Abraham van Helsing - 1st Doctor
Alice (from Wonderland) - 2nd Doctor
Elizabeth Bennet - 4th Doctor
Hercule Poirot - 6th doctor
Peter Pan - 10th Doctor

This would be awesome.

Although I think I would have Elisabeth Bennet with another doctor, maybe the 10th.

Well, they're both so witty (Lizzie & 4) it would be bound to be funny.

I'd have anybody with the 10th Doctor. Anytime.

Mmm I see where you are coming from, she certainly would be an excellent sparring partner.

Del Boy.

Probably the Seventh, they're about the same height!

Oooh, great thread. I would choose the Freak from Prisoner Cell Block H to travel with 6th Doctor. Just to slap him down sometimes.

Well, it would certainly put paid to the question - you're back in time, mate. Now pull yourself together.

Victor Meldrew....and Nine, Ten or Eleven

Is Victor Doctor Constantine's son?

And I know its been suggested elsewhere before, but how about a Sherlock one - or rather the Doctor teaming up with Watson?

Quite possibly.

Sherlock would be great I was thinking that too.

Also Two could team up with Frank Spencer.

Three and Aunt Sally?

Aww with a cup of tea and a slice of cake.

Ten could team up with Dr Gordon Briscoe from The Quatermass Experiment.

Nine and Claude Rains from Heroes?

Eight and the Three Muskateers?

Five and Tristram Farnon

Would quite like to see the Doctor and that other meddling monk - Cadfael

Genuinely love a Hyacinth Bucket character to travel with them as a permanent feature who maybe isn't an assistant but a secretary or a cleaner and lives in the TARDIS. You just see her every now and then with a duster and rolling her eyes at the Doctor's latest compantions short skirt.

Just there as a constant.
