Just curious in case this ever comes up. If Captain Marvel is on her supercharged click and she were to be healed by a game effect (support, hitting a Bounty ID figure, opposing game effects, etc), where would she heal to?

I don't remember if "you can't be healed onto a KO click" is still a thing, but if it's not, then she "would be KO'd" and would thus return to her "most recently noted click number," right?

Like bobcat said, she is going nowhere. From page 6 Core Rule Book
