[quote]So long as the adamantium suit isn't treated like Superman's skin I see no issue with that.

Oh sure, I'd just need it to maybe go toe-to-toe with your Wolverine character (if he has an adamantium skeleton) or at the very least delay your Superman character murdering him if ever. It could also be vibranium/carbonadium or some other metal that isn't quite as strong as adamantium but still lightweight. My intent for him is to make him more of a scientist and a political schemer than a pure fighter. Plus, the bionics and drugs he needs to maximize the suit’s potential are slowly killing him - another plot point.

Also another idea for a character arc: Panau's regime is generally very intolerant of superhumans [i]unless[/i] their loyalty to the government is unquestionable. So there could be like two camps within the government/military: those that believe the regime should use superhumans and those that believe otherwise, instead preferring to neuter their powers or kill them. My Vulture character could be on the anti-super camp while yours would be the poster child for the pro-supers. Then tensions could possibly develop as the Prime Minister's health fails and a power struggle starts to arise.
