10 out of 10 for devious deeds and brutal strength, Diesel 10 is a big bully and typically the one who initiates schemes between him and Cerberus.
With a giant claw on his roof, he’s often out to destroy the harmony of the railway, typically to prove that diesels are superior. While he can look silly at times, he’s a force not to be reckoned with. One minute he can whack himself on the head with his claw, the next he can demolish a wall if the job calls for it.
In spite of his terrifying appearance, however, he can be helpful if persuaded enough. Unfortunately, Diesel is usually too wrapped up in his own devious deeds to see reason and often gets him and his partner-in-crime into a lot of trouble with their schemes and bullying.
Fun Fact!
Diesel 10 was first brought over to help out the engines while Sir Topham Hatt went away...but only made trouble in the end!
