Heidern

Eight years prior to The King of Fighters '94 tournament, Heidern was promoted to his current rank for his exceptional proficiency in martial arts and strategy. Rugal, who caught wind of Heidern's high marks, stormed the base when he was away and killed fifty secret service officers on his arrival. When Heidern hurried back from his duties, Rugal deprived him of his right eye and deemed him unfit to be a part of his collection. Instead, he murdered Heidern's wife and child. Disgraced and alone, he developed his own fighting style and mercenary unit, the Ikari Warriors. Since then, he's pursued Rugal to avenge his loved ones' deaths.

Sometime before the King of Fighters tournaments, he found Leona as the last survivor of a destroyed village. The girl was amnesiac and Heidern adopted her to care for her. He originally forbid her to partake in any training yet became lenient due to her inclinations on the matter. His refusal to give her a formal rank is his way of protecting her from some of the dangers on the battlefield.

Beginning in The King of Fighters '96, he assigns Leona to take his place in the tournaments while he issues orders from the sidelines.
