## Biography

Opthomas Prime's first appearance was in TRAINS-FORMERS. On that day, Thomas and his friend, Vector are on their way home after installing his robot joints in himself from Sodor Cybernetics. Suddenly, a wirelessly-transmitted navigational assistant installed on him called Trouble Tron explains that Spencer the steam engine from the Mainland has gone berserk and transformed into a giant robot called Megatrain. As Thomas transformed into Opthomas Prime, he had a battle with Megatain as he shot fireballs on Thomas' left arm. Then he used a fire hose to extinguish Megatrain's fire. Luckily, the day is saved by Opthomas Prime.

Opthomas Prime's second appearance was in TRAINS-FORMERS 2OOT. On that day, Thomas and Vector are heading back and was later interrupted again by the Trouble Tron, explaining that Spencer has escaped. They answered that he is in the Smelters Yard and they headed in. Not Megatrain anymore, he is called Galvatrain. He opened a purple laser to weaken Thomas, but he called for help on Percy, James, Gordon and Henry to merge into Opthomas Supreme. Opthomas Supreme then handles the rest of the battle.

Opthomas Prime's third appearance was in TRAINS-4MERS. On that day, Thomas and Vector are back from vacation and they have been assigned to pull some freight cars loaded with top secret cargo to the Muffle Mountain Mlitary Base. Trouble Tron warns Thomas and Vector something is coming towards them. It turns out to be Bertie who tells them they don't know what they're carrying. The two then collide, causing the freight cars to explode. Lady then escapes from her boxcar prison and becomes Track Arachnis, an intimidating spider-like monster, leaving Thomas derailed and incapacitated. Vector and Trouble Tron are now stranded with no engines available to help. Vector then gets an idea to ***"Call the Girls"*** and together, Rosie, Mavis, Emily, Belle, and Molly combine into Rosimus Prime and try to stop Track-Arachnis, only to get their powers swiped. Vector and Trouble Tron are once again stranded not long before **Opthomas Prime** returns and kills Track-Arachnis with a shotgun, just before he almost immediately gets killed by a laser by Scrapwave. The episode ends with the words "TO BE CONTINUED".

Opthomas Prime's fourth appearance was in TRAINS-FORMERS Reborn. The episode starts with Trouble Tron being rebooted onto Thomas and starts to ask questions about Vector and then Trouble Tron realized that Vector is a teenager now. Thomas then bursts out of Ffarquhar Sheds and Vector is happy that Thomas is back. Then, the duo sees Uni-Galva-Deca-Mega-Scrap-O -Tron. Thomas realizes that the mech is controlled by Sir Bertram Topham Hatt and then a top hat train comes and pushes Thomas into the lake but he escaped just in time and transforms into Opthomas Prime and gets a little bit hit by Uni-Galva-Deca-Mega-Scrap-O-Tron then Thomas runs back to defeat Uni-Galva-Deca-Mega-Scrap-O-Tron but then the mech activates a laser that sends Opthomas Prime, Vector, and Trouble Tron back to Ffarquhar Sheds and then Trouble Tron says that Sir Bertram Topham Hatt has assembled the scraps of all the villains (except Lady) and he's stronger than every bad guy put together so Vector a button that says "Calling All Engines" and that means every engine on Sodor is gonna combine to build a huge robot called Opthomas Omega and then Opthomas Omega succeeds in defeating Uni-Galva-Deca-Mega-Scrap-O-Tron.
