#14 Matilda Roberts

Matilda discovered in her shy teenage years that she had the power to turn invisible at will. A few years later, she was invited by the government to be trained and go into action as a super spy.

Sadly for her government Matilda may well be the worst suited person to being a spy that there is, despite her ability to disappear. She is clumsy and forgetful, and easily distracted by, well, pretty much anything.
