Goeniko is an umbrella term used to identify a popular fan-made character for several characters, first designed, seen and made playable for the fighting game engine MUGEN. A reference to her as an independent character can be seen in the first pachi-slot game for The King of Fighters. Her first mod was made by Ahuron though several different versions of her have been made since then. She is also known by many other names such as Goenika, Amanda, Wind, Kazeko, Reas, Sheryl Wainwright, or simply Goenitz.
Goeniko made his playable appearance in The King of Fighters '98: Ultimate Match Online.
