Imagine a child who's power was so great as a child that all 9 of the great evils realized that this one person would bring about their destruction. The power so great in fact that they had to kidnap her and unable to kill her put her into sleep for 10 years so they all made armor powerful enough to seal away her power. Then they locked the armor and hid the keys to make sure she would never be able to unleash her full power.

Forgotten, and nearly made indestructible by this armor she eventually was awoken and now seeks to deal some serious vengance to some evil.
She is coming for those keys...
