Running From Betrayal

Jay, a hero traitor. Only a few know. Not even the #1 hero himself knows. She's an assassin for the League of Villains, and her quirk makes it extremely easy. She's never seen in action. But she's still the #3 hero. She doesn't appear or come out as an active or joyful person. She's actually really jumpy and nervous most of the time, but can also change and be overly confident and outgoing, making her both arrogant and jumpy. It's a rare thought that she might be caught or discovered as the traitor, but she knows with her quirk nobody can know. Or will.
