When word of a strange occurrence happening soon, Billy sets out to discover the truth. But what he finds is... disturbing... This AU was made as a challenge to make a whole AU in one week. The concept was decided by a spinning wheel. Unfortunately, this challenge was postponed, so it's just a regular AU now.

After Stepney and D261 leave Sodor, new engines are needed. At the same time, strange things begin to occur on Sodor. And caught at the forefront is Percy The Green Engine himself. Read as he proves why his legacy is remembered.

After years of disappearances, the engines are face to face with a threat thought to be long gone... This AU is the AU made for the one week AU challenge, where I make a whole story in one week. :)

A new company makes a deal with Sir Topham to have his railway transport their tankers around the Island. However, Oliver quickly grows fed up with it, while Duck gets suspicious about what the tankers are carrying. It all comes to a head when a massive explosion occurs at the Harbor, causing the chemicals to leak all over the Western side of Sodor. Now, it's up to Oliver and everyone else he meets to save survivors on Sodor. Will they succeed? Find out!

"It was big, it was like a man, and it was deadly. Everything that encountered it was crushed under its might immediately! Nothing could stop it, or even come close to matching its power! So, I'd be careful if I were you. Otherwise, you might be the next victim of The Titan of Sodor!" -Percy

Just a place to compile fanart and such. The cover may or may not be an Agony of The League edit :>

The three mains, the beasts, and several other roles were decided by a spinning wheel. This AU does actually have a rule for who lives and who dies, so I'm curious on if anyone can guess it :> This AU was first created October 16th, was finished October 17th, and published October 18th to ensure it's bad.

This story is based of memory from the other one so comment if I'm missing some parts from the original version. Originally made by TheRingGuy (Shanks) This was deleted off Wattpad since other people tried to recreate this I wanted to bring the story back to life. I do not own this story, If this gets taken down then I'm sorry"Join Sir Topham Hatt as he returns to Sodor with some of his engines to search the one they left for dead. They think the retrieval will be easy, but how wrong they were. Now they must once again fight for their lives in the place they called home but this time the threat is much larger than anticipated."

As it say's this is a remaster of Percy And The Deadly Comet. When two alien's make a comet that shoot's out laser's, and turns Henry into a monster, it is up to Percy and his friends to fight Henry and the alien's who made the comet. Thanks to ThomasStudios8 who let me make this.

"Tucker Hunterson was under the impression there was no one left alive. However, he couldn't have been any more wrong. Several of those engines were still alive. Our units are heading back to save those engines." -Colonel Patrick Osborne, February 11th 1987
