Eric Baker is an agent with the CIA.
Because of a horrific incident that happened to her sister when they were both young, in which the sibling, Claire, was kidnapped and held for four years, Baker is determined to never be unable to take care of herself. In fantastic physical shape, Baker has also earned black belts in three different martial arts discipline, not to mention the firearms training she got when she joined the Agency.
That same event also make of her a fervent champion of the underdog, especially children, and anyone who would inflict harm on a defenseless person and then come into reach of Baker will find the meeting unpleasant if not lethal. Baker does not accept excuses or apologies where kids are harmed.
