Hakkei

Hakkei (Fa Jin) is one of Sie Kensou & Shion's Throws in the King of Fighters series, first appearing in The King of Fighters '96 by Kensou, and last seen by Shion in The King of Fighters XI.

Description
Kensou puts his hand in front of his opponent, then blasts them away with a burst of blue energy.

In The King of Fighters '99, he gets a version without energy called Sunda (Short Strike), where he blasts his opponent away with a palm strike instead.

Shion's version has him thrust both his palms into his opponent's middle, blasting them back.
