Athena Asamiya is originally from SNK's video game Psycho Soldier and a descendant of Princess Athena from Athena. She later appears in The King of Fighters series and has appeared in each of its eleven editions. Athena is perhaps best known for changing her outfit and hair style for virtually every new KOF game. She is a modern day high school girl in Japan. Her psycho power is a legacy from her ancestor Princess Athena through her mother and it seems no one else in her family possesses the same power. She is a typical protagonist of Japanese animation culture with strong sense of justice and will to fight evil, help the weak and exercise hard for self-progress. Objectively, she also has gained lots of popularity to make her an idol because of her energetic exterior and warm soul, both inside and outside fictions. For a time, Athena was considered the mascot of SNK. She eventually lost this role to Terry Bogard due to the popularity of Fatal Fury. In her bio, Athena considers Terry to be a very rude person in reference to this.
