Sie Kensou/Story

Psycho Soldier
Sie Kensou is a lively young man born with Psycho Powers. He teamed up with his friend, Athena Asamiya, to fight in the name of justice. In Psycho Soldier, he was one of the "heroes of light" who defended the world from the Shiguma forces. His psychic powers can allow him to transform into a dragon.

Athena: Awakening from the Ordinary Life
Kensou remains relatively the same as his other incarnations. The main difference from this Kensou is that he doesn't exhibit psychic powers during the majority of the story. He declares himself to be "Athena's knight" and often rushes to her aid when she is in danger. He recklessly runs into one of her teleportations and joins her search in Tantauls' headquarters. While she is battling the Tantauls system, he temporarily shields her by using his previously latent psychic powers. During the ending, he comforts her brooding by trying to not over think things and repeats some of his kenpo teacher's advice. He also tries to confess his feelings for her but is interrupted when Athena spots a healthy Rika.

The King of Fighters
He is one of the young disciples of Chin Gentsai who wields Psycho Powers. Both he and Athena are trained by Chin to prepare for "the worst case scenario of oncoming evil" and use the tournaments as a method of training for such an event. Plans go awry when Kensou loses his powers in The King of Fighters '99 yet saves Athena with a previously unknown latent energy.

It is later revealed to be the Dragon Spirit (の, Ryū no ki), a power he somehow shares with younger teammate, Bao. He regains his powers and masters this newer power in The King of Fighters XI, much to the satisfaction of former NESTS member, Ron. The deeper meaning of the Dragon Spirit's importance has yet to be revealed. It's probable that the Dragon Spirit is a reference to Kensou's ability to morph into a dragon from Psycho Soldier.
