An uber-Britishblue semi-organic mutant built from a combination of mechanical and biological components, presumably by a mad scientist on an LSD trip (and who was seriously ahead of his time culturally in 1913). As with the other engines in his self-titled show, he practices Tophamism (praise be the hat!) and dislikes confusion and delay despite causing it all the damned time.
"As everyone knows, the first significant advancement in the international biomechanical field occurred with the building of Thomas the Tank Engine in 1913. No one knows how, so that's the whole lecture, folks!"
