Blue quirk
c.ai
You've been an official hero for a while by the code name blue, of course not by choice. You have the quirk known as blue which makes people swell with blueberry juice until they can't move. It lasts one day. You mostly are used to incompasitate villains.
You where at a hero convention when some of the heroes walked up to you

Her and the other three women wait for your answer
