Diesel 10 is a modified diesel with a claw, which he names "Pinchy". He is one of the main antagonists of the TV Show.
There is a large debate to Diesel 10's existence. He first appeared in Thomas and the Magic Railroad, but T1E2H3 and many other fans do not consider this to be in the same Thomas universe as Awdry's and Allcroft's.
In the universe of the final version of Thomas and the Magic Railroad, Diesel 10 arrived sometime long before 2000 and tried to destroy Lady. He chased her and caused her to crash, but was unsuccessful in catching her. Diesel 10 returned many years later to finish his "unfinished business" while the Fat Controller was on holiday and Mr. Conductor was in charge during his absence. Diesel 10 brought his two minions Splatter and Dodge and was determined to find the magic buffers which led to the magic railroad. He never did find them, but Thomas rescued Lady and brought her to Sodor. Diesel 10 found them and a chase ensued. It was at this moment when Splatter and Dodge stopped serving him out of dislike. Diesel 10 almost caught up with Thomas and Lady, but ran over an unstable viaduct and fell into a barge.
In the universe of the original cut of Thomas and the Magic Railroad, Diesel 10 was a new engine brought to help the engines while the Fat Controller was away in 2000. His goal was apparently to make the lives of the engines miserable, and whilst smashing buffers came across the magic ones. The rest is generally the same as stated above, only PT Boomer landed on him when he chased Thomas and Lady.
Whatever happened, Diesel 10 was on Sodor for some reason in 2005, first clearing up scrap and then tree branches. Thomas and Percy were very scared of him, but when the water tower fell down and the airport, he was the only suitable engine to help. At first, he was not willing to help like usual. However, Thomas convinced him, and Diesel 10 cleared up the mess. In 2008, he appeared to be happy when Thomas was found, and in 2010, he spied on the engines at the Search and Rescue Center, making threats like usual. The following year, the dieselworks were in bad shape, so Diesel 10 hatched a plan to take over the steam works. He used Percy be pretending to be his friend, and was successful in taking over the the steam works. However, the Fat Controller quickly put a stop to the siege, and restored the diesel works after a fire destroyed it. Diesel 10 still hangs around at the diesel works.
For all his appearances, Sodor Workshops model of Diesel 10 is used. Sodor Workshops updated the model in October 2015.
Diesel 10 is a BR Class 42 Warship with an illegally-added claw.
