I'm making a villain for my party to go up against, who is a metal manipulator. Not sure yet if I'm going to have his power be magnetism or just metal shaping.
Anyway, his super outfit is, of course, made of metal.
The problem comes in when one of the heroes has the ability to manipulate metal as well, and isn't the type to worry about the morality of making bad guys armour grow spikes into them. And when another of my intrepid 'heroes' uses guns and likes filling people with lead.
So the obvious answer to the second hero, to me at least, is to make him immune to damage from things made of metal. His powers just kind of make anything metal stop just before it can harm him, whether it be bullets, brass knuckles, baseball bats, whatever. But that still leaves his suit as manipulable by the first hero. How do I stop that, how do I make it so every round my villain isn't distracted by constantly having to undo his suit fusing together?
Is it an Immunity to Magnetic Effects? Immunity to Damage from Metal? Immunity to Metal Effects? A Reaction power of some type? Do I just make it an unstated Power Stunt? And how do I stat the costs of such?
