Might be easier if you explain your character idea first, and it gets decided on from that.

I think the rules are basically "don't make anything stupidly overpowered". I mean, Jack might be really strong, but only in specific situations. She's not great with tech beyond suit maintenance, and while in a face to face fight she turns into a meat grinder, she's not much use outside of combat or preparation for combat. She's strong, but in a limited field.

So yeah, describe your character idea, it's easier than setting up a hard list of what can and can't be done.
