Mr. Karate (Mr. カラテ) is the alter ego of Takuma Sakazaki that has appeared in a handful of SNK games. His first appearances was in Art of Fighting as the final boss. He wears a Tengu mask to hide his true identity. His name wasn't originally stated in-game, though the announcer did refer to him as "Mr. Karate" in versus mode. He was officially named as such in later games.
He is voiced by Eiji Tsuda.
When Takuma was forced to work as Geese Howard's henchman, he donned the Mr. Karate persona to protect the honor of his family and school. He was feared by many as an unbeatable and merciless opponent. Sometime during Yuri's kidnapping, he either told or left clues of his true identity to his daughter. Although he could have done the same for Ryo, Takuma decides to keep using his Mr. Karate persona when he faces his son. He was curious to see his son's true strength and didn't want their family ties to hold Ryo back. He is impressed by Ryo's progress and his real identity is revealed after his first defeat.
