Editing Diesel 10 (section)

== Personality ==
Diesel 10 is ten out of ten for devious deeds and brutal strength, and a blast from the past who hates steam engines. Diesel 10 is also an evil, conniving, manipulative, bullying and raving diesel locomotive. He absolutely despises steam engines, would call them taunting names like "Puffball" (Thomas) and "Teapot" (Toby) and is not above do anything to get rid of them if possible. He is Sodor's strongest (but not quite largest) diesel, his power being enforced by his slightly malfunctioning claw, Pinchy. He can use this deftly, and is even able to use it to make a sculpture. Pinchy, though, seems to have a mind of its own, as it has been shown to "punch" Diesel 10 in the face from time to time, which he loathes. All engines, steam and diesel alike, fear or respect him.

He is also shown to be extremely psychotic and murderous, as he once tried to push James and Junior into the smelting pit at the Smelter's Yard. But Junior used the last of his gold dust to teleport him and James to safety, much to Diesel 10's shock.

Despite his brutality, some of his demeanour appears to have cooled, and his behaviour has apparently improved enough that Sir Topham Hatt allowed him back to the Island. He gets along enough with the other Sudrian diesels, but his efforts to help are often only when it suits his personal interest and he still harbours his scheming ways and anti-steam sentiments.
