Scarlet was a newspaper reporter who, after sticking her finger in a ray from a machine her scientist father had created, found she was invisible, clothing and all. It was not long before she found that she could change from visible to invisible by pinching a nerve in her left wrist. Scarlet used her ability to become a better reporter and take down such villains as the King of the Slums and others.

As the name suggests, Scarlet O'Neil can turn invisible by pinching a nerve on her left wrist.
