^ All the marvel power disc they have planned so far will all come out at launch in one wave. It's highly likely she'll be apart of the Wave 2 of Marvel figures since the recent villains trailer shows her fighting loki (very short).
I'm guessing NPC, if she was spotted in the Avengers playset then she won't be playable, you probably unlock her for use in the toy box. You could use her to set speech bubbles to to create RPGs...
