Caine is a tall man with a hunched posture, long arms, and abnormally large forearms and hands. His hair is stringy and gray (or brown in promotional artwork), and he has a black horseshoe mustache. He wears a drab green baseball cap and matching uniform with ripped sleeves, as well as brown gloves, black boots, and a tool belt. He keeps his eyes covered with protective goggles and carries a large wrench that he uses as a weapon.
Caine was a mechanic who worked for the Skull Cross Gang. Since childhood, Caine had a compulsive hobby of disassembling machines and mechanisms, to where he would often sneak into the local car factory with his father's tools to dismantle and then reassemble the various parts and cars he got. Into his later years, Caine's obsession for destroying and restoring appliances and gadgets got him into trouble that forced him to run away from home and ended up staying at a scrapyard to make a living and satiate his fixation. Caine is also said to be antisocial and doesn't like to hang out with people.
Due to his experience of handling machinery and makeshift engineering, Caine is said to have built strength to where he can easily bend steel, but has no fighting experience. He has great reach with his wrench, and is fast on his feet in spite of his size. However, he is nearsighted and will position himself very carefully before he attacks. He will also swing his wrench immediately after recovering from a knockdown, whether or not anyone is in front of him. If enemies get too close to him, he will grab them and bash them in the head with his wrench for major damage.
