— His skin is unorthodox. It doesn't feel like steel, but has a deflective power that's greater than the material, so it's very hard to get him out of the way using traditional modus operandi—if you really hate him, there's always the option of ruining his suit by shooting it and then hiring him for a hit, though. He won't refuse a request, no matter who gives it. It's fun to watch.
— He does not have any superhuman biological weapons and thus resorts primarily to the use of his gun.
— He's gained the title Nemean Lion, despite looking to be made of silver and not gold. Nobody knows if he can be dispatched in the same way it was, but most people think it's safe to make the inference, since he's very careful not to allow himself to be restrained in any way.
— He is legitimately in monochrome; he's not human. The fluid that runs through his veins would probably be black if anyone saw it.
— He has a very serious demeanor, and a propensity to take even joking threats as if they were genuine. It is generally not a good idea to fool around with him verbally unless you are prepared for the potential consequences, as he is alert and has a weapon on him at all times.
— He's got some floral "tattoos" on his back; they're inconspicuous and actually not meant as generic "criminal" ones, though it's often hard to tell the difference. Nobody knows how in the world they got there: some people have actually made it their life's goal to hunt down the artist.
— Fairly gentle in his private life. His private life does not comprise most of his life.
— A tall man, in both the literal and metaphorical sense. He's surprisingly refined for what he does.
— If he weren't always wearing his suit then maybe he could pass for having a troubled romantic type disposition. As is, people are more concerned about...well, his face than what's on it, or about what he's doing with his hands.
— He's not good enough at doing makeup to disguise himself as a human.
— He's not impartial and not ashamed of it. If you're near and dear to his heart he will kill to keep you safe from harm, and he's not so changeable that he could easily shoot a past flare.
