Angela Belti is a reoccurring character in the Power Instinct series. In the first Power Instinct, Angela was voiced by a male Atlus employee and appears with a huge, muscular body in the game. Her original design was depicted as a "large muscular character". In Power Instinct 2, she was voiced by a woman and appeared more feminine.

In CR Goketsuji Ichizoku, Angela has the ability to transform into a less corpulent version of herself dressed as a nurse, known as "Devil Nurse".

The inspiration for Angela's visual design comes from an early 90s Japanese TV commercial for an energetic drink produced by Pip Fujimoto. The commercial stars professional female wrestler, Reggie Bennet, which closely resembles Angela's original design.
