Re: How would Stronghold imprison your character?
Scales: Can't think of much other than hot sleep. Hard to hold a cross of The Thing & Dr. Strange.
Calico: Strong room should do it. She'd probably have to be in solitary. Hated by a lot of the criminal element (and some of the heroes) and she'd be a "I'm not trapped in here with you, you're all trapped in here with me" type.
Ice Pirate: She'd be underestimated the first dozen times. She'd be very good at escaping and would have a lot of fun with it.
"What do you mean she handed you a get out of jail card!"
"it was very convincing..."
High levels of gadgeteering, persuasion, forgery, and many other skills.
