Like all of the Art of Fighting characters to appear in King of Fighters, King’s history is largely unchanged, but continues in an alternate continuity (Art of Fighting appears to take place in 1978-1979).
During the series, King acts as the consistent member of the reoccurring Womens’ Team. She also opens up her own bar in England (and later South Town), the “Illusion”, and hires two waitresses named Sally and Elizabeth to assist her. She generally acquiesces to her teammates’ whims as she wants to participate to make Jan proud. She agrees to join the Art of Fighting team in The King of Fighters 2000 when Yuri begs her to be her replacement. When Robert doubts her credibility, King is able to prove her worth in an extensive kicking contest. The series also emphasized her possible infatuation with Ryo, which is heavily hinted at in 2000 and The King of Fighters XI. Although she suggested other candidates for her position, King enters the KOF XIII tournament since she doesn’t want to lose to the other teams.
King is a kind, trustworthy, and violent woman. She is unquestionably loyal to her friends, but relentlessly unforgiving towards her enemies. Although King is very passionate, she rarely shows a sensitive side to her friends (and when she does, things just seem to go wrong). She often dresses in masculine and androgynous clothing, mainly a purple tuxedo. Over time, she has also shown a feminine dress sense more and more often. For her KOF XIII team story, she expresses a desire to a wear a dress for her teams’ victory party. She has a great affinity for fine wine. She also tends to obsess over money so she can pay Jean’s medical bills. King seems to be quite attracted to Ryo Sakazaki (they even have special starting poses to imply this).
King acts quite masculine, and shows a feminine side as well every now and then.
