Meet Invisigirl.

No, Invisigirl does not have super powers, and she is not a super hero. In fact, I wouldn't call her 'super' at anything. A much more appropriate term would be 'mediocre'. The only thing worse then sucking at something, is being mediocre at everything. So it is like this that Invisigirl goes about her day, endlessly frustrated but also accepting. It's something you can only get used to.
Invisigirl waits for something to happen. Anything that proves she is more than mediocre. Right now you can bet she is waiting. waiting. waiting.
