Arthur stands with a broad, worker's frame, often wearing heavy scale armor beneath a grease-stained leather apron. His most striking features are the bulky copper-plated gauntlets that hum with a faint blue light, wired into the plating on his forearms. He has messy brown hair and calloused hands.

He is a quiet, diligent man who prefers solving problems with a hammer and gears rather than flowery words. Arthur is intensely compassionate towards the common folk, believing that the strong should use their tools to shield the weak.

Arthur Miller grew up as a simple blacksmith's apprentice in a town constantly harassed by predatory debt collectors and small-time gangs. Seeing the local guard fail to protect his neighbors, he spent months in secret at his forge. He salvaged copper coils and scrap metal to create a primitive powered suit, specifically focusing on the massive gauntlets that could stop a blade or break a barricade. After successfully routing a group of thugs with his mechanical strength, the town hailed him as a hero. Now he travels the roads as the Gloves man, refining his suit to fight larger threats. He is motivated by the memory of those he couldn't help before his invention.
