Tommy S. Gordon

Where a head and shoulders would sit, Tommy carries the front end of a steam engine, an oversized cartoon face fitted into the smokebox itself. Everything from the waist down stays conventional: a bodysuit finished off with boots, gloves, and an ornamental belt.

The number 4 painted on his sides ties the design to Gordon of the Railway Series, while his given name and the locomotive body point at Thomas the Tank Engine. He has never been adapted into the anime.

Tommy picks his fight the moment Koichi Haimawari, known as The Crawler, steps out of a coffee shop, and he gives chase on the spot. Pop Step tries Christopher Skyline first, finds him busy, and calls Midnight instead. Midnight passes the job along to Eraser Head, who is browsing Recycle Shop: Hoppers nearby with the Hotta brothers.

Koichi waves the surrounding civilians clear and opens up with repulsion blasts from his Scrappy Thrust Style, which only makes the villain angrier. He then slips away and hands the matter over to Eraser Head, who defeats and arrests Tommy without much ceremony.

He resurfaces during the Naruhata Lockdown among a crowd of reformed villains. Rhino Man, Horse Man, Willy Wanda, and Emperor Yotsuura stand with him, all of them cheering The Crawler on as he takes Number 6 apart, the villain fighting in Destruction Style form.

Tank Engine is the Quirk responsible for the locomotive occupying his upper body.

Increased Speed: Because steam machinery makes up his top half, Tommy runs extremely fast. He kept pace with The Crawler at a point when the vigilante could match a speeding bus.
