Flipping a Villain card.

I’m new to Sentinels of the Multiverse so I have a question about basic game play. When you flip a villain card like Citizen Dawn does their HP reset or do they keep the current HP?

Unless a card states otherwise (like Baron Blade's character card restoring him on his flipside), a card keeps its current HP when it flips.

Wow, imagine if their hp did reset. Akash'Bhuta would be impossible! Actually, Omnitron would be even more impossible, because at least you can potentially control when Akash'Bhuta flips…
