Noooo, you didn't miss anything. This was after I was first brought here. I was kidnapped by an alien race who wanted to put me on trial for crimes the older version of me committed.

WELL.
Turns out Older Me had a thing called The Phoenix Force in her for a long time, and due to some mental manipulation, a lot of anger, and a lot of mental stress, it made her go full-blown nuts, and she DESTROYED A PLANET.
