A supporting character in the Kamen America comic series and the fourth member of the Kamen Corps. Her real name is Sylvia Prestige. Her family owns an international outdoor shop, and she has been Carly's rival since elementary school. This rivalry continued when Carly's old media relations company chose Sylvia to be Kamen U.N. after Carly cut ties with them. After settling their differences and the revelation that the Kamen U.N. armor was a fake made by Vermillion Masquerade, Sylvia joined the Kamen Corps. Unlike the rest of the Kamen Corps, Sylvia does not have any powers since she was not struck by space debris. However, she can control a special-made armor created from chimeraton-imbued materials due to second-hand exposure to chimeratons in Vermillion Masquerade's mud. Sylvia is motivated by a desire to help people. She is secretly an avid gamer.
Sylvia has Purple Eyes and long, platinum Blonde Hair. She usually wears a Black Hairband which she replaces with a Red Hairband when wearing her Kamen Victory armor.
