Personality:
She doesn't care about others really, and stays alone most of the time. The way she talks may seem odd to others, but it seems completely normal to her. She seems really tough and cold on the outside, but in actuality she just cares about her inventions, and doesn't want anyone to ruin them, as they are her life, basically.

Backstory:
Amanda is an inventor, and creates several gadgets that she then sells to larger companies for mass production. To test them, she usually tests them on herself, as she doesn't have anyone to test them for her. One day she ends up finding Oliver and Catherine, or more like they wandered into her lab. She thought she got them to leave, but they continued to come back. Soon she might find herself getting attached to them, even if she didn't think she ever would to someone.

Extra notes:
She has basic psychic powers. She can levitate objects or shoot psychic blasts at others. And she can sometimes read someone's mind.
