According to the game's illustrator Akira “Akiman” Yasuda in the Street Fighter X Tekken Artworks artbook, he wanted Cammy to serve as a counterpart to Chun-Li, citing how Cammy is from the West and has upper body strength, in contrast to Chun-Li's eastern origins and lower body strength.

He also stated he modelled Cammy after the pigtail assassin Misty who appears in the manga Wounded Man. Her arm protectors are based on the ones used in Masamune Shirow's Appleseed.
