He is voiced by Naoki Sagawa.
Hired sometime prior to The King of Fighters XIV, Hein works as Geese Howard's butler. In KOF XIV, after many years of absence from the King of Fighters tournaments, Geese decides to form his own team and has Hein join and Billy Kane in order to investigate the Jin scrolls' prophecy regarding Verse.
Although modest, mild-mannered, and never seeming to break his polite tone, he does have a sadistic side. He has a distant respect for all that he encounters but is not above roughing them up to the extreme, or being snarky, especially to Geese's adversaries. Still, as a butler, he knows when to pull his punches and admire true power.
- Gravitokinesis - Hein can command a mysterious red energy, its overall properties being similar to gravitational fields.
- Gravity Sweeper - He can lay down small pools of damaging red energy on the floor.
- Gravity Bomber - He can produce a large explosion of red energy around him to repel foes.
- Gravity Trap - He can cover a large area of the floor with his red energy. Any opponent standing on it is pulled into the floor and vulnerable to attacks.
He fights in an elegant fighting style known as "Gambits" with moves named after chess terminology.
