Steam Smythe

History
Colonel Walter P. Smythenson was a very prolific inventor in the mid 1800s. With the likes of fully autonomous steam-powered assistants and other creations that were beyond anyone else's comprehension, he was years ahead of his time. However, in 1882, electricity became popularized as a more efficient means of power than steam. Fueled by the dismissal of his work, he wished there to be a reckoning upon all those who wronged him.

However, Smythenson contracted an illness that led him to be incredibly reclusive, he threw himself into his work until his death in 1896, but he had a final trick up his sleeve. He instructed one of his automaton assistants to remove his brain upon his death, and preserve it in a robotic steam-powered facsimile of himself. Over the next few hundred years, his lab would collapse in on itself, the majority of his creations would weather away without the care of their master. And yet, somehow, the brain was preserved inside the robotic copy.

A few hundred years later, the remains of the lab were unearthed, and a group of archaeologists brought the robotic body back to their base of operation. During an examination of the technology, the gears started turning with a groan. The man had somewhat effectively cheated death, having given himself new life. The process wasn't without its flaws though, as the only things he retained were his intelligence, his inventive capabilities, and his final wish to rid the world of modern technology.

No one heard from the group of archaeologists who found him, they all mysteriously disappeared. The man returned to what remained of his lab and continued his work just as he'd done. He couldn't remember his name, but a worn away metal plate on a wall read "Smythe", which he adapted into his new identity - Steam Smythe.
