(Cool Accepted, Sean said he would post tmrw and if he doesn't I will start this without him haha, co owner override)
(Wolverine only had hard metal and regenerative abilities. Also, metal skeleton would't make you stronger. Strength is based off of muscle. Same with speed. His speed would actually be reduced due to weight, and it would make him less stealthy because he would make more noise. Only thing that could be enhanced is flexibility, but that depends on the metal and would most likely make the bones brittle.)
(A metal skeleton isn't realistic for an assassin OR for a spy movie. Could also be considered god modding. A metal skeleton would be better suited for a sci-fi type rp.)
(Servos in his joints make him stronger, and as for the flexibility he doesn't have the locked elbows, knees, or other joints that stop a normal person, ie I could in fact bend my arms backwards at the elbow, its viable as it makes me potent in hand do hand... And I do it because I can do it, I did add in the factor of cold and you obviously didn't read my flaws, I'm not god modding if I have obviously hindering weaknesses*
Servos also help his speed and stealth isn't much of a matter considering 1: I'll be sniping. Or 2: I'll be the violent and messy assassin
(Flexible metals are known for breaking apart in the cold. And when it would be in the shape of a bone, it is less malleable than if it was sheet metal. Then in heat, it would become too soft from body heat and would become distorted.)
Either way, there's still the problem of the metal distortion. You would need a metal that has a high boiling point that also isn't very reactive so it doesn't create other chemicals with things running through you. Also... What about bone marrow? You need bone marrow.)
Titanium is strong, resistant to heat, and fairly tame, and as for the bone marrow I have to do blood transfusions often to keep my blood cell count up
(He is going against the laws of science. As well, I think this is supposed to have close to current technology. With this technology, there is no way to remove a skeleton without damaging the rest of the body.)
