This is all your fault. You'll never laugh at me again... The rights of Bio-Fused engines will be ignored no more! The secrets of Sodor will be revealed; the state's sponsored torture of engines MUST BE STOPPED! And we will not stop until the Island of Sodor is recognized as a refuge for all engines!

Thomas The Tank Engine: Project G-1

Annie, my love, what's wrong? What's the matter...? What's happening?! Annie, please...stay with me! I can't go on without you! Stay! Stay with me!! NOOOOOOOOOOOOOO—!!!
~ Diesel witnessing Annie Clarabella's death, Project G-1

Kevin Diesel and Annie Clarabella met as rail enthusiasts and got married within weeks of meeting. Shortly after the wedding, they became Bio-Fused.

Diesel and Annie spent thirty years as transports (for Diesel, a British Railway Class 08 diesel, and for Annie, an LB&SCR orange Stroudley coach). However, Annie's operation wasn't fully successful, as her stem cells split, resulting in two coaches. With the Bio-Fused twin; Clarable turning out to be deformed. After an incident with some passengers, Annie would spend the rest of her life with Diesel, while Clarabel would be taken to HiT Logistics.

In there, Clarabel was melted down by John, Terry and a surgeon.

Clarabel's meltdown caused Annie to catch fire and explode as a result of the telepathic link the two twin coaches held. This traumatized Diesel immensely, and he flew into a rage while attempting to break down the doors of the shed he had been kept in.

After the deaths of both Annie and Clarabel, Diesel got furious at HiT Logistics for murdering his wife; however, his plan to get his revenge on HiT Logistics was to team up with a protest group known as the Thomas fans, forming the Sodor Liberation Front.

While the Thomas fans were in front of HiT Logistics, Diesel charged at the HiT Logistics building in a suicidal attempt to bring it down. After crashing through the front wall, Diesel collided with the tank containing the reprogrammed cells, triggering its escape and formation of Project G-1. It is assumed that Diesel was either killed in the collision with the tank, or was somehow fused with Project G-1 and died when the amalgamation was killed in the Blue Mountains.

"All right, people, let's tear this f****n' shed down!"
~ Diesel in Roly's Christmas Special

Diesel was first seen as a DJ at the party being held by the engines in Roly's Christmas Special. Diesel received a much greater role in the 11th episode of the series, Roly And Diesel. Diesel was set to pull Roly as his coach of choice, and appeared to be enthusiastic about this, but James showed up and provoked him. Enraged, Diesel suddenly transformed into Diesel 10 before throwing Roly all the way over to the mainland, before turning back to normal off-screen.

Thomas' PC Adventures

He first appeared as a villain in Thomas' PC Adventures, just like the Thomas series. And he was in Tidmouth's lodge instead of Toby.
