The King of Fighters Ash Saga/Shion

Shion is a video game character in The King of Fighters series and the sub-boss of the The King of Fighters XI game.

History
Shion works under Magaki and moves for the resurrection of the seal-moved Orochi. He uses a form of barehand wushu, a spear, and a rope dart for her moves. He is very eager to accept challenges.

Shion is first shown in the mid-game cinematics after the mid boss fight, showing her talking with Magaki, who warns her of betraying him. Next, Shion is seen taking a break after turning the finals arena into ruins. After she is beaten, Shion gets surprised by Magaki who whisks her away to a different dimension. The most likely case is that since she is definitely upset by this, Shion doesn't waste time at all when she finds an opening on Magaki's defense when he's trying to flee via dimensional rift. Shion kills Magaki by driving her spear right through his heart, killing him quickly, even though she is then trapped in the other dimension. SHES A GIRL.

Trivia

 * Shion is one of the most fluidly animated character to ever grace the 2D The King of Fighters series. This might be due to the fact that Shion uses the forms of Wushu which itself involves a lot of graceful and complicated moves.
 * Shion is said to be a favorite amongst the KOFXI designers. This may be evident of her being one of the characters that were made into toy give-aways in SNK Playmore's 2005 Year End Party, just months after the release of KOFXI.
 * Unlike Mukai and Magaki, Shion will actually be defeated once the fight with Shion is complete.
 * Although it is not known for sure whether Shion himself killed Magaki, in the endings gallery for the game, Magaki's death scene is labeled "Shion's Betrayal." Also, earlier in the game, Magaki warns Shion not to betray him, which was probably foreshadowing for such an occurrence.
