Final Genesis (comic story)

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

Now: The TARDIS arrives with a rising tone, rather then the traditional "vworp, vworp" the first sign for Ace and Benny that something is not quite right. Later, unable to get a straight answer out of the Doctor, they discover that the world itself isn't quite right. They see Dinosaurs and later are arrested by strangely familiar soldiers working for URIC rather then UNIT. The Doctor ingratiates himself into the URIC command because 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 soon becomes embroiled in the prevailing mystery, people (Humans, Silurians and Sea Devils) have disappeared across the globe and unnatural beasts are attacking URIC. After one such attack, one of the beasts is captured and autopsied, revealing it to be a gestalt, a combination of the best genetic features of all three dominant species. After capturing a double-agent in URIC, they discover that Immorkal, a rogue Silurian scientist and eugenicist, is behind the creation of the hybrid beasts and has developed a gas he plans on releasing across London, and then the globe, a gas that will kill two-thirds of the infected and mutate the survivors. However, during a URIC attack on his base, an accident releases the gas into Immorkal's base causing Immorkal to die, while the Doctor coldly watches, protected by his Time Lord immune system and cardiac-bypass ability.

Prior to 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.

Characters

Continuity

 * The Silurians first appeared in DW: Doctor Who and the Silurians and the Sea Devils in DW: The Sea Devils.
 * The Doctor, Ace and Bernice Summerfield travel to another alternate universe where Silurians and Sea Devils are present in NA: Blood Heat. In a possible nod to this, Final Genesis states the number of possible futures and divergent timelines from the first Silurians story is near endless.
 * the TARDIS lands with a different sound (a rising hum rather then the traditional "vworp vworp") Benny and Ace comment upon this, it's the first sign that something is amiss.
 * The TARDIS console room changes appearance in the middle of the story with no explanation.
 * It's implied that the Doctor knew about the death of his other self, Benny muses that other versions of himself could be the closest thing he has to family, so came here to avenge him.
 * As in The Robots of Death the Doctor's enhanced respiratory system means he is unaffected by airborne chemicals (helium in Robots of Death, here a mutagen that affects all Earth sentients (ie Silurians, Humans and Sea Devils) that mutates them into a gestalt version of the best traits of all three, or kills them outright).
 * Ace's skill and familiarity with firearms is again shown with her fighting alongside URIC forces.
