Hot Girls of Doctor Who

Much like secretaries, librarians are also hot -- the younger ones, anyway. Zoe is one such librarian with one added detail: she's from the future. She works aboard the space station W3, also known as the Wheel. She aids the Doctor in stopping a Cyberman invasion and quickly joins him aboard the TARDIS for more adventure. Aside from being hot, Zoe is also a genius, solving complex mathematics with the speed and certainty of a high-tech computer. Now, her age is a bit of a mystery, but the actress playing her was at least 20 at the time, so calling her hot totally doesn't feel creepy.

Secretaries, librarians... who else, who else... ah yes, scientists! Scientists are hot! And that's just who Liz Shaw happens to be. She is an Oxford-trained scientist, hired by the Brigadier to be UNIT's scientific advisor. To add to her hotness, she holds degrees in several fields, including physics, astronomy and medicine... so I guess that also makes her a doctor -- and doctors are also hot. Her first encounter with our Doctor came in the form of helping him defeat the Autons and the force that controlled them.

Now, Jo is not a scientist or a librarian. She isn't even a secretary, but she is still hot. She becomes the Doctor's companion when Liz Shaw leaves UNIT. Her assignment, however, is purely due to the fact that her uncle is a high-ranking UNIT officer. She is young, naive and not very bright. This perplexes the Doctor, but he just hasn't got the heart to tell her and ask the Brigadier for a new companion. But as hapless as she may have been, Jo endured her fair share of adventures with the Doctor and proved to be quite the companion.

Nobody's sure why, but being evil appears to add to a person's hotness. Perhaps it's the mystery, perhaps it's the icy coldness that it takes to commit evil acts. In any case, the Rani has got the evil thing down pat. Some would argue that she isn't really evil, though. There is some truth to that. The renegage Timelady doesn't commit evil acts to take over the world! She commits them all in the name of science. Simply put, she has no grasp of the concept of good and evil, and does whatever it takes to get her experiments completed -- including enslaving an entire planet's population just to have enough test subjects and a quiet place to carry out her SCIENCE!
