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. Shion uses a form of barehanded wushu, a spear, and a rope dart. Shion is also very eager to accept challenges. It does bear mention that according to SNK and the KoF XI storylines, Shion is indeed male, but very feminine looking.

Shion is first shown in the mid-game cinematics after the mid boss fight, where Magaki warns Shion of betraying him. Next, Shion is seen taking a break after turning the final's arena into ruins. After being beaten, Shion gets surprised by Magaki and whisked away to a different dimension. The most likely case is that, getting definitely upset by this, Shion does not waste time at all when finding an opening on Magaki's defense while trying to flee via dimensional rift. Shion kills Magaki by driving the spear right through his heart, killing him quickly, though still trapped in the other dimension.
