Omega/Non-valid sources

Omega was depicted in several sources considered NOTVALID by Tardis Wiki.

Facing the Sixth Doctor
In 2054, the Fusion Energy Research Network, a research complex connected via space elevator to the FERN Spacelab, began running experiments on duplicating Fusion reactions safely on Earth. At the same time, other technicians studied Anti-matter. The existence of these two studies attracted Omega, himself a Solar engineer. In 2056, Omega encountered the Sixth Doctor at the Spacelab and attempted to force him to give up the secrets of time travel and his TARDIS.

Omega planned to get revenge on Gallifrey by trapping it in stasis, as they had done to him, and then subjugating the Time Lords. He planned to do this by causing the Fusion Energy Research Network complex to go nuclear, turning the Earth hotter than the Sun and giving him a power-source to accomplish his plan. To gain the trust of the FERN staff, Omega stole the body of the Doctor and took control of the Fusion tests. (NOTVALID: Search for the Doctor) While some variations of this source indicated that Omega was successful, that the Earth was destroyed, the Doctor killed or imprisoned, and Gallifrey enslaved (NOTVALID: Search for the Doctor: Marker 1, Marker 4, Marker 25, Marker 27, Marker 28, Marker 29, Marker 31) one specific account stated that with the help of the Time Lord Drax, K9 Mark III, and a human named Dinah, the Doctor was freed and Omega was defeated before his plan could be completed.
