Mr. Karate

How Mr. Karate joined the Tourney
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.

Mr. Karate was later used in The King of Fighters series as comical relief. He appeared in some of the Art of Fighting Team endings, claiming that he is the true master of Kyokugenryu Karate and that Ryo, Robert and Yuri have much to learn. When they tell Takuma to take off the mask, he replies he is not Takuma Sakazaki and does not know him. He eventually takes off the mask, revealing to them what they already knew. Later, when he is hospitalized due to poor health, he humorously uses the Mr. Karate mask to sporadically sneak out of the hospital to train. King reports the stories from the hospital staff to him, and Takuma claims his innocence as usual.

When Takuma dons the Mr. Karate form, he stages a fighting tournament against B.L.A.D.E. (Builders of the Legacy After the Destruction of Earth). The winner would be his worthy adversary. Eventually, Cross made it and swore to settle things with Mr. Karate at the second Smash Bros. Tourney.
