Mukai

Mukai is the main villain from The King of Fighters' 2003.

Story
Mukai is one of Those From the Past, who is trying to awaken Orochi so that his master can absorb it's powers. His origins remain a mystery. He decides to use the King of Fighters tournament to gather energy for Orochi, but since he didn't wanted to call attention, he decided to manipulate the tournament indirectly. He orders his subordinate Botan to manipulate Chizuru Kagura and Rose Bernstein to host the tournament, while he tries to break the seal of Orochi. Mukai is amazed to see the prowess of the fighters of the tournament, admiring their vast potential. As he breaks the seal, he watches as Chizuru Kagura is defeated by the winning team, deciding to show himself and challenge the team. He is defeated, but he then stands up as if nothing had happened, and disappears, leaving Shion and Magaki to take on from where he left.

Personality
Mukai is a very proud warrior, who never underestimates his adversaries. He loves to talk in grandiose declarations, as if he is a prophet.
