A couple of months back I came across this webcomic about The 10 Doctors done by a storyboard artist name Rich Morris who is an obvious long time fan of Doctor Who. He incorporated a story featuring all 10 of the Doctors and most of their companions.
I came across the story as it was nearly done - so that means I had a lot to read to catch up which was great. Not knowing much about the Old Who universe, but enough to get by, I was still able to enjoy and understand the comic. It's a rough pencil sketch but still I think it looks awesome.
He's finished up the story since then and has started another one that seems to involve the Eighth Doctor & the show Forever Knight called "Forever Janette". If you go directly to his site the new comic of the day.
This link will take you straight to
The 10 Doctors page 1. On the FAQ page there is a listing where you can see where the various Doctors were in their timeline before they were pulled into this story.
Also it seems that he has decided to put the comic up on You Tube and add a little extra sound effects and an awesome title sequence. I'm not sure how many have been edited this way but it's another way to read the comic.
Even if you deicide to read the comic in web form I still suggest you at least watch the video through the opening title sequence. It's rather cool.
