[@Goldmarble] He could be a homeless guy wrapped in a very large trenchcoat. Maybe he's covered in bandages. He's known to the public as a hobo with a physical deformity but his super hero identity would still be somewhat a mystery.

His bone plate body thing is fine (I imagine him to be like mutant marrow or spike) but regeneration would have to be quite limited as a secondary power.

Hmm, if that's allowable, then....yeeesss.
Always have had him being covered up; deep hooded coats, baggy pants, gloves, heavy work boots, etc. Tries to avoid being seen, because people tend to react badly, and he's had...history. Physical appearance has always been hard to describe, until I watched something again. Something old; Grig from The Last Starfighter movie. A bit rougher, and less uniform, heavier set, shorter, broader, squater, etc.

The idea for his powerset, was actually a very slow acting reactive adaptation mechanism; essentially, it has taken years of getting the shit kicked out of him, to grow the dermal armour he has. And by slow acting, I mean slowly, like needing to be electrocuted six or seven times in a week, just to kick in for the body to start trying to generate methods to resist it, stop it, or do something to prevent the harm from occuring. Even then, it would take months of being electrocuted, daily, before it came up with some means of truly protecting him from it. But it isn't just his skin, it is everything: his bones are stronger and denser, his muscles have greater resistance to damage (cutting, crushing, etc). The regeneration has always been a slow-acting thing, definitively not "Wolverine" class in healing a bullet wound in a couple minutes to a couple seconds, depending on who wrote it. More like, taking over an hour.

Essentially, his entire powerset is devoted to being resiliant, tough, and extremely survivable. He is strong, but only to peak human capability (Dead lift ~1000 lbs, etc). He isn't fast, but he can run for a long time, so long as it isn't hot out...as his protection, has eliminated his ability to sweat. He can sustain a higher core temp than a normal human, but that doesn't mean much, as his overall endurance in any sort of moderate climate is still at, or less than average, due to his inability to simply get rid of the heat. Inversely, he can tolerate extremely hot environments for very short durations; his skin that insulates him from getting rid of heat, also insulates him from heat for a couple minutes at best. So he can run into a burning building, stay there for maybe three minutes and get out, but that heat will still transfer through and he will burn...just after the fact.

Other weakness? He cannot damn well float. Due to the increased density of...well, everything about him? He simply sinks in water, no matter how hard he tries to swim against it. He avoids any sort of location with deep water, because he can tank being punted through some walls, being shot, impaled, whatever. But drowning? He is not so sure he can survive that.

Personality wise? Cynical, with reason. Finds it hard to trust people, but he wants to. Is kind, gentle, supportive and caring of those who he does trust. Fatherly (He is over 60 years old!)
