Characters

The Doctor: The Doctor is a timelord from the planet Gallifrey. He usually goes by the name John Smith. He is 903 years old and travels in time and space in his TARDIS. It is in the shape of a old police box, but used to be able to take any shape or form using the chamelion circuit. That broke. The Doctor has 13 lives, and has been noted that all timelords have 13 unless taken over by a human body. He usually travels with a companion but is sometimes without and gets really lonely.  

Rose: Rose was the first companion of the reboot in the series in 2005. Before she met The Doctor, she worked in a normal store in the ehart of London, but was attacked by Autons in the basement of the store, and that's when she met The Doctor! Ever since Rose met The Doctor she has always been there for him, and when they split up, she always found a way to be with him again!    

Martha:  Martha is a 23 year old popular companion of the tenth Doctor's. Before she met him, she was working in The Royal Hope Hospital in the heart of London before it got transported to the moon by the Judoon. She is a confident companion and hard working, and has always been there for The Doctor when he has needed her most.

Donna: We first met Donna in a one off Christmas Special, when she was about to get married but was transported inside the TARDIS while in mid-flight. She then met The Doctor once again, in a sky-scraper facing the evil Adipose. She travelled far and wide with The Doctor, facing menacing Daleks and Adipose, but eventually lost the Doctor when she mixed his DNA with herself. She now has no memory of The Doctor or her adventures with him.

Captain Jack Harkness: We first met Captain Jack in The Empty Child. He is also a time traveller, and has a very big spaceship, that was parked on the side of BIG Ben during the blitz. He has made many re-appearances and bow works for Torchwood.
