Omega

Omega is a Time Lord who was good friends with Rassilon. Omega was called Omega as when he was younger he did a stupid thing in a science test and got the worst mark Omega. Omega invented a metal called Valdiam. He also invented time travel. How he did this is this. Gallifrey has 3 suns. Omega thought he could destroy one of the suns and could create a super nova. But you would have to get someone to do it close to one of the suns. Sadly Omega got sucked into the super nova and into another dimension made of antimatter. Luckily Omega's valdiam armour protected him from the antimatter. Soon Omega became paranoid that Rassilon planned it would happen and he would take the glory. Rassilon not wanting to give up on him got The Third Doctor.  Rassilon also had the data of The Second Doctor and first and got them to help. Once they got to the other dimension they found out Omega's body was destroyed but the armour was keeping him alive. The next time The Doctor sees Omega is when Omega takes over The Fifth Doctor 's body but The Doctor defeats him. The last time Omega has been seen is when The Sixth and Second Doctor destroyed Omega once and for all. Omega was another of The Doctor's childhood heroes. Omega like Rassilon has a seal devoted for him. Bye.
