Omega (Doctor Who)
Character history
Character history
-----------------

Omega was a stellar engineer and a member of the High Council on [Gallifrey](/wiki/Gallifrey "Gallifrey") who developed the [Hand of Omega](/wiki/Hand_of_Omega "Hand of Omega"), a remote stellar manipulator which could be used to control the reactions within a star. Using the Hand, Omega performed adjustments on a star near Gallifrey's in an attempt to provide a power source for the [time travel](/wiki/Time_travel "Time travel") experiments he conducted with [Rassilon](/wiki/Rassilon "Rassilon"). However, Omega was thought to have been killed in the resulting [supernova](/wiki/Supernova "Supernova"), which then collapsed into a [black hole](/wiki/Black_hole "Black hole").

Rassilon subsequently captured the [nucleus](/wiki/Black_hole%23Singularity "Black hole#Singularity") of the black hole and used its power to perfect time travel technology. Rassilon then took control of Gallifrey as Lord President. The nucleus eventually became known as the Eye of Harmony, and Omega's name passed into heroic legend.

Millennia later, during the events of the *Doctor Who* serial *[The Three Doctors](/wiki/The_Three_Doctors_%28Doctor_Who%29 "The Three Doctors (Doctor Who)")*, it was revealed that Omega had not died, but had rather been sent through the [event horizon](/wiki/Event_horizon "Event horizon") into an [antimatter](/wiki/Antimatter "Antimatter") universe and had been trapped there since then; although he was able to shape that universe according to his will, it meant that he could not leave that universe. His exile and solitude turned him quite insane, and he sought revenge on the Time Lords for "abandoning" him. Despite the Third Doctor's assurances that he was revered among the Time Lords and still remembered fondly, Omega still sought retribution. He made two attempts in the television series to re\-enter the positive matter universe: in *The Three Doctors* where he attempted to force the Doctor to take his place in the antimatter universe so that he could depart it, and in the serial *[Arc of Infinity](/wiki/Arc_of_Infinity "Arc of Infinity")* where he attempted to create a new body for himself using the Doctor's biological data. Both attempts were thwarted by the Doctor, with his universe being destroyed in *The Three Doctors* when he was tricked into touching the [Second Doctor](/wiki/Second_Doctor "Second Doctor")'s [recorder](/wiki/Recorder_%28musical_instrument%29 "Recorder (musical instrument)")—which had remained matter when the others were converted into antimatter—and his new body was seemingly destroyed in *Arc of Infinity* before it could convert back to antimatter and destroy Earth.
