Sai

Sai is a secondary character in The King of Fighters series, first appearing in The King of Fighters 2001 in one of Lin's win poses. He is a member of the Hizoku assassin clan and one of the Four Devas. Sai is known for his unique appearance: a tall, muscular figure with a strangely shaped head, orange skin, and a Yin-Yang symbol on his head. He is a man of few words but has a fondness for gambling. In the story, Sai works alongside Luan and Chat, all of whom are members of the Hizoku. While his combat abilities are not fully displayed in the games, he is said to be skilled in shooting techniques and precision. Sai's fate is somewhat mysterious in the story, as he is implied to have possibly joined the traitor Ron or encountered a supernatural event, leading to his disappearance with his companions.
