Heather McCrimmon

Heather McCrimmon was a companion of the Tenth Doctor.

Biography
Heather was, in her native time, a history student at Edinburgh University. She joined the Doctor so that she could experience historical events first-hand for her history essay. (DWAM: The Chromosome Connection)

Heather was later joined in her adventures with the Doctor by Wolfgang Ryter.

During a return to Edinburgh University to meet her professor, she was led into a trap by the Mozhtratta. Heather was so affected by the Monzrhatta's machine that if she took a single trip in the TARDIS she would be ripped apart by time radiation, from which the TARDIS would normally have protected her. She gave an emotional goodbye to the Doctor, saying at least she was back at home. (DWAM: Dead-line)

In the years following her travels with the Doctor, Heather pursued a career in archaeology, and a freelance alien hunter by night like Wolfgang, with whom she was reunited four years after her travels with the Doctor ended. Both Heather and Wolfgang saw the Doctor one more time when he saved their lives and then departed, to check on Rose in 2005, and to face his regeneration. (DWAM: Lucky Heather)

Personality
to be added

Behind the scenes

 * Heather McCrimmon has the distinction of appearing in more individual stories -- approximately 50 -- than any other companion ever featured in Doctor Who comic strips, including those published in DWM and in the 1960s. Based on individual adventure count, she could be considered one of the Doctor's longest-serving companions, TV or spin-off.

Continuity

 * The World Shapers in Doctor Who Magazine, which featured a much older Jamie McCrimmon, had implied that any family that he might have had had long since left him to become a village pariah. Jamie stated in CC: The Glorious Revolution that he and Kirsty McLaren had "more bairns than there are days in the week". Heather is then possibly a distant descendant of Jamie and Kirsty.
 * In the order of publication, Heather became the Doctor's companion after Donna Noble and the information given to you when you were creating a character for the comic's competition confirms this. Given statements made in the post-DW: Journey's End era regarding the Doctor refusing to take ongoing companions after Donna, Heather's presence either violates TV continuity or her travels in the TARDIS take place at some earlier point in the Tenth Doctor's life, likely between DW: Voyage of the Damned and DW: Partners in Crime.

Creation
Heather was created by 10-year-old Joanne Hall in a competition sponsored by Doctor Who Adventures to create a new companion to appear in the magazine's comics.
