The Seventh Doctor once met a future version of himself at Bonjaxx's birthday party on Maruthea. It was unclear from what point in the future this incarnation originated.
Biography
Accompanied by his companion Ria, this version of the Doctor greeted his seventh incarnation and Ace at Maruthea during Bonjaxx's birthday celebration. (COMIC: Party Animals) Though close-mouthed about it, he implied the Time Lords no longer had the power to enforce the First Law of Time over him, so he could converse with his seventh incarnation with impunity. This was most likely due to the destruction of Gallifrey during the Last Great Time War. (TV: The End of the World)
Appearance
This Doctor had short, dark hair and a receding hairline.
His outerwear consisted of a dark suit jacket with light-coloured piping along the lapels and he carried a toothbrush in his outer breast pocket for reasons unknown. He also wore a badge shaped like a teapot. (COMIC: Party Animals)
Overall, his appearance closely hewed to that of the "false Ninth Doctor" created by the Eighth Doctor and Feyde to help defeat the Threshold. (COMIC: Wormwood)
Behind the scenes
This version of the Doctor was certainly based upon Nicholas Briggs' physique. In a 2000 interview, however, Briggs failed to dismiss his interviewer's assertion that it was also a representation of the Doctor he played in the fanon Audio Visuals productions that were more-or-less contemporaneous with Party Animals.[1] Still, he made no positive assertion in that interview that the two Doctors were the same. And there is really very little in the actual body of the comic to suggest that the "Briggs Doctor" is anything more than just an unspecified future version of the Doctor. In any event, the Audio Visuals productions are outside the scope of this wiki.
The only properly licensed Doctor Who fiction that even marginally ties into this character is Wormwood, a DWM comic story from 1998. There, the Eighth Doctor appears to regenerate, but really his "new self" is actually Feyde in disguise. That disguise is someone who looks strikingly like the Party Animals Doctor, down to the fact that he carries a toothbrush in his breast pocket.
It is considerably unclear what this means. Perhaps Feyde and the Eighth Doctor created this new persona on the basis of the Seventh Doctor's experience in Party Animals. Maybe the "Feyde Doctor" had time to sneak away for a bit, pick up someone named Ria, and pop back in time to meet the Seventh Doctor. Or maybe there's no connection at all. All that's certain is that neither narrative gives us anything clear to connect these two Nick Briggs-based Doctors.
