Omega Omega , born as Peylix , also called Omegon and worshiped as Ohm , was a great intergalactic engineer and co - founder of Time Lord society , but circumstances bent his mind so that he threatened the entire universe . He was the only person ever to live within the anti - matter universe , which he subsequently ruled over , with the permission of the anti - matter creature . However , his existence in this realm robbed him of his body and left only his conscious will intact , a realisation that twisted him into murderous insanity aimed towards the Time Lords , whom he blamed for his imprisonment . Biography . Early life . Omega was one of the most significant figures in Gallifrey an history . He appeared in the ROO texts , as later scholars on Gallifrey would call them , alongside Rassilon and the Other . ( PROSE : " Goth Opera " , " The Infinity Doctors " ) He later said he was named Peylix . He had taken the name Omega in response to his teacher , Luvis , who had awarded him a grade of Omega for an essay he had written . In it he had explored the possibilities of increasing the Gallifreyan power by exploding a star . The resulting energy could be harnessed for time travel . This was seen by his teacher as madness and pure idiocy . The Omega was the lowest mark possible , and Peylix was left with a humiliating nickname that endured even when he and a friend of his , " Razz " , effected this plan , forcibly creating the Time Lords . ( AUDIO : " Omega " ) By the time of his " death " , Omega had married a Gallifreyan known as Patience . ( PROSE : " The Infinity Doctors " ) Achievements . During the Dark Times , Omega and Rassilon ( TV : " Remembrance of the Daleks " ) enabled the people of Gallifrey to achieve time travel . ( TV : " The Three Doctors " ) The Other assisted them in this . ( PROSE : " Lungbarrow " ) Omega may have also have played a part in the creation of the living metal Validium . ( TV : " Silver Nemesis " ) According to a transmission from Anathema ( which may have been influenced by Faction Paradox propaganda ) , when Rassilon first attempted to create and harness the power of a Black hole , before Omega ' s development of the stellar manipulator , he accidentally punched a hole into another plane of existence , and the Great Vampire s swarmed into our universe , beginning the Eternal War . According to this source , an engineer ( strongly hinted to be Omega ) subsequently plugged up the black hole , making it resemble an ordinary planet . ( PROSE : " Interference - Book One " ) A stellar manipulator , the Hand of Omega , one of Omega ' s many creations , could make stars go supernova . ( TV : " Remembrance of the Daleks " ) In an alternate timeline not one , but two , Hands of Omega existed . ( PROSE : " The Infinity Doctors " ) With the power unleashed by a supernova the two hoped to generate enough power to travel through time . ( TV : " The Three Doctors " ) . Gallifrey ' s galaxy had only one Population III star at that time . They decided to destroy that one . ( PROSE : " The Infinity Doctors " ) The star , in an area known as the Sector of Forgotten Souls ( AUDIO : " Omega " ) in the constellation of Ao , ( PROSE : " Lungbarrow " ) bore the name Qqaba . ( COMIC : " Star Death " , PROSE : " The Infinity Doctors " ) The " death " of Omega . The stasis halo of Omega ' s Starbreaker , the " Eurydice " , was sabotaged , exposing it , and the Starbreaker ' s crew , to the fury of the black hole . There were several accounts concerning the details and reasons for the sabotage , ( COMIC : " Star Death " , AUDIO : " Omega " ) though one Gallifreyan wrote that Omega had " got his sums wrong " and was simply not within a safe distance when the star exploded . ( PROSE : " A Brief History of Time Lords " ) Historically accounts depicted that Omega ' s assistant , Vandekirian , had sabotaged the mission on behalf of Rassilon . However , feeling guilty over his betrayal , he cut off his own hand as recompense . Omega did not accept it , and cut off his other hand , placing it in his stellar manipulator , which was later to be known as the Hand of Omega . Upon which , the Eurydice was destroyed due to Vandekirian ' s actions . ( AUDIO : " Omega " ) In his own distorted memories , Omega recalled that Vandekirian was at least partly responsible for the sabotage . He had discovered that detonating the star would jeopardise the existence of a race called the Scintillan s . When he realised what would happen , his guilt caused him to destroy his own hand , since its activation required his palm print . However , Omega cut off his other hand to activate it . Although , the Fifth Doctor revealed that the history with the Scintillans was a corruption of his own memories , over the guilt of accidentally killing the race himself , and incorporated it to reconcile his reasons for Vandekirian ' s betrayal . The Doctor hypothesised that Vandekirian had either sabotaged the mission on behalf of Rassilon , or he had just succumbed to madness . ( AUDIO : " Omega " ) According to another account , Fenris the Hellbringer , ( COMIC : " Star Death " ) an agent for the Order of the Black Sun , ( COMIC : " 4 - D War " ) sabotaged Omega ' s Starbreaker . This was to ensure that the initial Gallifreyan time travel experiments never came to pass , so the Time Lords " [ would ] be annihilated before they [ had ] even come into existence " . However , Rassilon ' s interventions dispatched Fenris and the time experiments succeeded . ( COMIC : " Star Death " ) Rassilon prevented disaster from overtaking the other three Starbreakers ( COMIC : " Star Death " ) and wept over Omega ' s death . ( PROSE : " Lungbarrow " ) The survival of Omega . The Doctor , like most Gallifreyans , grew up to revere and admire Omega as a great hero . ( TV : " The Three Doctors " ) The Hand of Omega had , meanwhile , survived and returned to Gallifrey . The First Doctor would later obtain it for himself . ( TV : " Remembrance of the Daleks " ) Omega had transported through the black hole into another universe made of anti - matter . Omega shaped the universe by force of will and access to the black hole ' s singularity . He could even create simple life . Radiation destroyed his body . The gauntlets , armour and helmet he had designed to protect him from the corrosive effect of the anti - matter now constituted his physical form . At first he shaped his new world into a paradise . As the centuries rolled by he grew weary and depressed , feeling abandoned by his fellow Time Lords . The landscape slowly transformed into a drab , grey desert . The universe that had become his home was unstable , unable to exist without a powerful will to give it form ; he was trapped . ( TV : " The Three Doctors " ) Against the Time Lords . After thousands of years in the void , Omega hit upon a plan of revenge : a captured Time Lord could be forced to take his place , and Omega could leave and wreak vengeance on Gallifrey . This plan was inspired by the Verdigris , who had travelled into the anti - matter universe in an attempt to get the Third Doctor released from his exile on Earth . ( PROSE : " Verdigris " ) Using the black hole , he drained power from the Time Lords to stop them from interfering . He sent an amorphous life form and other , more humanoid servitors to find the exiled Third Doctor and take him into the black hole . The High Council , unable to send anyone to assist the Doctor , decided to have the second incarnation of the Doctor help rectify matters , subsequently contacting and sending his first self to advise them . Omega brought both incarnations to his domain , entry into which converted all matter into anti - matter . When Omega removed his helmet to prepare his departure , he discovered that the anti - matter universe had completely dissolved his physical body . He could not leave his universe ; he existed only because his will insisted that he exist , but his will was all that was left of him . Consumed by rage and despair , Omega swore to destroy all things . The Doctors offered freedom to Omega : in actuality the Second Doctor ' s recorder which the Doctor ' s TARDIS had accidentally shielded from conversion into anti - matter . The Doctors attempted to trick Omega into touching the recorder but instead only infuriated him . When Omega lashed out he knocked the force field generator to the floor , causing the recorder to make contact with the floor and creating a violent matter - antimatter explosion which seemingly killed Omega , collapsing the antimatter world . ( TV : " The Three Doctors " ) Omega survived the explosion , but became trapped in a crimson bubble of time . He began taking spacecraft into his realm , including the Rigelian Seventh Fleet , the disapperance of which was investigated by K9 Mark I . Now calling himself Omegon and claiming that the Time Lords had made him Emperor and then betrayed him , he used the thousands of spaceships he had collected to launch an attack on Gallifrey to get his revenge . However , K9 launched his spacecraft K - NEL at the rocket stores of Omegon ' s flagship , destroying it in a colossal explosion which seemingly killed Omegon . ( PROSE : " K9 and the Time Trap " ) Affiliation with the Arc of Infinity . Though he was once more thought destroyed , Hedin of the High Council contacted Omega to help him . Omega had gained control of the dimensional gateway known as the Arc of Infinity . Through the Arc , he had a gateway between his own universe and the universe of matter , though he still had no physical form . Omega also had a TARDIS and a servant he had created , the Ergon . Omega needed to bond with another Time Lord using his biodata extract . ( TV : " Arc of Infinity " ) On Earth at the time , Omega sent the Ergon to survey the planet , and it ended up in Perivale , where it met Dorothy McShane working in a fast food restaurant . She didn ' t realise it was an alien , and gave it some fries , which it took back to Omega . Omega didn ' t like them , claiming they didn ' t have any salt on them . ( PROSE : " Anti - Matter with Fries " ) Hedin transmitted to Omega the biodata extract for the Doctor , by this time in his fifth incarnation . Omega established a base in the Earth city of Amsterdam , navigated the Doctor ' s TARDIS into the Arc and began to link the Doctor ' s biodata with his own . The Doctor faced execution on Gallifrey to stop Omega ' s return . This was part of Omega and Hedin ' s plan : they rigged the execution to hide the Doctor and Omega in the Matrix , safe from Time Lord detection . Omega shifted the Arc to Gallifrey in order to gain control of the Matrix and used its power to create a physical body for himself . The Doctor tracked him down and sabotaged his equipment in Amsterdam , forcing Omega to step into the physical universe before the transfer was made stable . His new body , a replica of the Doctor ' s , began to decay and revert to anti - matter . Thwarted and maddened by defeat , Omega willed the acceleration of his conversion to anti - matter to destroy the Earth rather than return to the universe of anti - matter , but was destroyed by the Doctor using the Ergon ' s matter converter . ( TV : " Arc of Infinity " ) After Amsterdam . Omega was recreated by using the Doctor ' s biodata . However , this had the effect of causing Omega to develop a split personality , being both Omega and the Doctor , but the Doctor persona wasn ' t aware of his Omega personality . In Amsterdam , Omega secretly boarded the TARDIS of a visiting Time Lord historian and broadcaster , Professor Ertikus , who was in the city to see the site of Omega ' s destruction . Ertikus travelled to a Jolly Chronolidays trip to the Sector of Forgotten Souls , with Omega stowed away onboard . Before the trip , Omega met an employee of Jolly Chronolidays , Sentia , with whom he fell in love . He told Sentia all about himself , including his split personality disorder . Omega planned to use the Jolly Chronolidays trip to the Sector of Forgotten Souls to return to the anti - matter universe with Sentia , because he found he disliked living in this universe , and wanted to return to his universe where he had godlike power and remained safe . While travelling to the Sector of Forgotten Souls , the Doctor persona met Sentia for the first time ( although Sentia already knew about this Doctor personality ) while the ship was docking into the leisure base . There he met Daland ( an actor who played Omega in the recreations of Omega ' s experiments ) and Tarpov ( another actor who played Vandekirian , Omega ' s assistant ) . Tarpov succumbed to the Vandekirian personality , left behind by the psychic residue from Omega ' s experiments . He tried to stop Omega ' s experiments by attacking Daland and crushing his own hand in machinery , to stop his hand print being used to release the Hand of Omega , but Omega entered and stopped Tarpov from crushing his other hand . While Tarpov was recovering , Omega tried to kill Tarpov , believing he would give away a secret that he wished to keep quiet , but the medical robot knocked him unconscious . The Omega persona directly communicated with the Doctor persona inside Omega ' s mind . " Omega " tried to convince " the Doctor " to help him travel to the anti - matter universe with Sentia , and " the Doctor " accepted . Meeting Ertikus for the first time , and discovering he was a Time Lord , " the Doctor " used Ertikus ' TARDIS to travel to the recreated " Eurydice " so he could fulfil his mission . But Sentia kidnapped Daland , and stole a shuttle , so she could get there , and could use Daland to conduct the marriage ceremony , but Tarpov stowed aboard and escaped onto the " Eurydice " . Tarpov revealed to Sentia that by destroying a star , to create the Eye of Harmony , he would cause the death of a native race called the Scintillan s , however , Omega continued anyway . Omega then killed Tarpov . Ertikus tried to meet Omega , but discovered that " the Doctor " had been in contact with him all along . Omega revealed himself to Ertikus and then killed him . After they were reunited , " the Doctor " sent a telepathic message from Ertikus ' telepathic circuit to the Time Lords explaining everything about the situation to them , so they could send help . Daland and Sentia looked for Ertikus , and Daland found his recorder robot , which had recorded Ertikus ' death . Daland realised that " the Doctor " had killed him , and tried to attack the Doctor . Seeing the footage for himself , " the Doctor " realised he was merely a product of Omega ' s split personality disorder , which was finally confirmed by the arrival of the real Fifth Doctor in his TARDIS , who had been sent by the Time Lords . Feeling the effects of mental trauma , Omega escaped and began to suffer flashbacks of his earlier life , and the circumstances which lead him to take part in the time experiments . After hearing about the Scintillans from Daland , the Doctor confronted Omega , and revealed that the Scintillans weren ' t a part of the time experiments , but a memory Omega had taken from the Doctor . The Scintillans were a species the Doctor accidentally killed when he tried to save some Lurman s . The Doctor believed Omega had subconsciously used this to explain away Vandekirian ' s betrayal . Sentia ( taken over by Vandekirian ' s personality ) attempted to pilot the " Eurydice " into the anti - matter universe , so Omega would be trapped again . The Doctor and Daland escaped , while Omega was trapped on the ship , as it and Omega were supposedly pulled back into the anti - matter universe again . ( AUDIO : " Omega " ) Return . For centuries on Gallifrey , the Adherents of Ohm were a secret society that worshipped " Ohm " , ( AUDIO : " Intervention Earth " ) a name for Omega used by those who believed him to be a " trapped god " . In another universe , Savar met " Ohm " within a black hole , but The Doctor . ( PROSE : " The Infinity Doctors " ) Omega manipulated the Adherents of Ohm to steal the Hand of Omega from Gallifrey and use it to create a black hole . Omega then lured Tauras and brought him and Ace ' s TARDIS into the anti - matter universe . When he met Romana he thought the Time Lords society had fallen so low to allow a president from the House of Heartshaven . Possessing Tauras ' body , Omega took Ace ' s TARDIS and escaped the anti - matter universe , knowing that it would allow him back on Gallifrey as it was known to the Celestial Intervention Agency . ( AUDIO : " Intervention Earth " ) Romana sent Irving Braxiatel back in time to change history so that Omega would never escape the anti - matter universe . ( AUDIO : " Enemy Lines " ) Personality . Omega was very bitter about his fellow Time Lords , who he believed sacrificed him to attain greatness . He held eternal enmity towards his race , and sought to avenge himself against them . Countless aeons alone left him with little care about anything , deeming the destruction of reality as a " spectacle to behold " . He also became paranoid and developed mood swings . He lacked any restraint and had a vicious temper . The Doctor considered him to be a madman . However , he was not without heart , and appeared enchanted by small things such as a child ' s smile and a steam organ during his brief escape from the anti - matter universe , suggesting that his extreme fury was merely the by - product of loneliness and despair . ( TV : " The Three Doctors " , " Arc of Infinity " ) Despite being insane , Omega was noted for his extremely strong will , which allowed him to reshape the antimatter universe in the singularity to create an environment as well as servants that suited him . This made him linked to the antimatter realm , as his will alone kept it alive and prevented his escape . He was completely unaware of the fact that his body had corroded away as a result of prolonged exposure to the antimatter realm , and that both his physical form and the world he created were made by his will alone . ( TV : " The Three Doctors " ) In Time Lord culture . Rassilon , the Other and Omega were the three most important figures in Gallifrey ' s history . ( PROSE : " The Ancestor Cell " ) The Feast of Omega was a holiday that was celebrated on Gallifrey . ( PROSE : " Happy Endings " ) The Belt of Omega was part of a Presidential dress which the Fifth Doctor was forced to wear . Seeing him fit it on , Tegan Jovanka amusingly suggested that Omega had tried to steal his body because he was jealous . ( AUDIO : " Time in Office " , TV : " Arc of Infinity " ) The Omega Arsenal was a stockpile of forbidden weapons locked away in the Time Vaults . ( TV : " The Day of the Doctor " ) Secret societies on Gallifrey were dedicated to the worship of Rassilon , Omega , and the Other . The Adherents of Ohm were one dedicated to Omega , ( AUDIO : " Intervention Earth " ) " Ohm " being a name for Omega used by those who believed him to be a trapped god . ( PROSE : " The Infinity Doctors " ) Coordinator Jarad was once heard to exclaim " Omega ' s ghost ! " to express shock . ( AUDIO : " Legion of the Lost " ) In a parallel universe where the Sixth Doctor led Gallifrey in the War , a time dreadnought was named the " Glorious Aspect of Omega " . ( PROSE : " The Quantum Archangel " )
