Final Genesis (comic story)

 was a 1993 Doctor Who Magazine comic. A part of the brief run of comics that were closely integrated into the Virgin New Adventures continuity, it starred the Seventh Doctor and Benny, and, for the first time, a post-Dalek Wars Ace.

The story itself posited the notion of the Doctor watching over a parallel Earth in which a dead, alternative Third Doctor had brokered a successful peace between humans and Earth Reptiles at the end of TV: Doctor Who and the Silurians. This story therefore offered a second parallel Earth within the Virgin New Adventures continuity that had to do with a more dominant Silurian race.

Summary
Then: A bomb explodes, killing the Third Doctor and Brigadier Lethbridge-Stewart.

Now: The Doctor's TARDIS arrives with a rising tone, rather than the usual "vworp, vworp", the first sign for Ace and Benny that something is not quite right. Unable to get a straight answer out of the Seventh Doctor, they find the world itself isn't quite right. They see dinosaurs and are arrested by strangely familiar soldiers working for URIC rather than UNIT. The Doctor ingratiates himself into the URIC command; the late Doctor's assistant is familiar enough with regeneration and time travel to work out that although this is a Doctor, he is not their Doctor.

The Doctor becomes embroiled in the prevailing mystery. People across the globe — humans, Silurians and Sea Devils — have disappeared and unnatural beasts are attacking URIC. After an attack, one is captured and autopsied. It is a gestalt, a combination of the best genetic features of all three dominant species. After capturing a double-agent in URIC, they discover Mortakk, a rogue Silurian scientist and eugenicist, is behind the creation of the hybrid beasts. He has developed a gas he plans to release across London and then the globe. It will kill two-thirds of the infected and mutate the survivors. However, during a URIC attack on his base, an accident releases the gas, killing Mortakk. The Doctor watches coldly, protected by his Time Lord immune system and respiratory-bypass ability.

Before returning to the TARDIS, the Doctor visits his other self's grave, leaving Ace and Benny to muse about their "accidental" arrival and how for the Doctor, his parallel selves could be the closest thing he has to family.
