For a fan-made animated short this is actually pretty freakin' damn impressive. This is a anime style short of Doctor Who that was created by Paul "OtaKing" Johnson. He spent about two and a half years working on the 13-minute short, and it turned out great. He ended up using the third Doctor, Jon Pertwee, as his central character.
Here's a note from the creator,
All 13 minutes of the completed fake Doctor Who 80s-style anime. Drawn, animated and partially voiced by myself. Some bits are good, some bits are poor, but on the whole it turned out okay, I think. Enjoy! This is old school Who, so fans of the new reboot show may be confused by the fact that the Doctor is doing martial arts and Cybermen say "excellent." Watch the classics and you'll understand. You'll also become almost instantly more handsome by watching classic Who.
I actually wouldn't mind seeing more of these get made. This would at least make for an awesome web-series. There have already been a few attempts at getting a Doctor Who animated series off the ground, but none of them have turned out as good as this.
