Mainstream universe

Parallel universe
In an alternate reality where the Doctor never appeared on Earth, the Silurians awoke and began their plans to retake the planet which they ultimately succeeded. Over the next twenty years, they began to terraform the world back to the time of the Silurians original rule which drove Humanity to the brink of extinction. It was in this era that Imorkal was born who was the hot headed offspring of Silurian leader Morka and his wife Chtaachtl.

At the time, he was part of a group of Silurian hunters that tracked down and exterminated any Humans they found. Among his band included his bodyguard Vronim and his mentor Chtorba who had found the trail of this reality's version of Jo Grant. Imorkal eventually discovered a human encampment in Cheddar Gorge but was ambushed before he could report this back to his people. In the resultant battle, Vronim was killed and Chtorba wounded as well as captured by the humans. The wounded Imorkal himself, however, managed to hide himself in the dead body of his dilophosaurus mount. Once his ambushers had left, he attempted to retreat to the old bunker in Wenley Moor in order to summon help.

Whilst on his journey, he encountered Ace and Alan in their jeep who were also heading towards Wenley Moor. Imorkal used his third eye to attack Alan which caused the keep to crash but before he could continue his assault, he was knocked out by Manisha. After Alan's death from his injuries, Ace in a fit of rage attempted to kill Imorkal in cold blood but Manisha stops her and instead they manacle the Silurian to the jeep. When Imorkal later regained consciousness, he snapped the lock of the manacles with his third eye.

Later, Imorkal caught up wuth Ace and Manisha in the ruins of the old Silurian base in Wenley Moor. There, he attacked ace and she attempted to defend herself with a Sonic screwdriver. However, due to her suffering from Race-memory malaise, she was unable to properly work the device and instead pulverises Imorkal's brain with sonic pulses that killed him in the process.
