Kinnikuman refers to him as Master (師匠, Shishō). He has only taken three students in his life, Kinnikuman, Mantaro Kinniku, and Chaos Avenir. He has an eagle on his chest and a mahiole-like crest on his head. His name comes from Hawaiian King Kamehameha.
Kamehame is a Veteran Choujin. In all of his 999 title defenses, he never lost once. When he first appears, he lives in Hawaii as Jesse Maivia's personal assistant. At age 70, he is Hawaii's greatest wrestler. He would have gained a 1000th victory but he lost to Jesse. Kinnikuman got to Hawaii and ended up challenging Kamehame because Kamehame agreed to let him fight Jesse if Kinnikuman could get through him. Kinnikuman lost within seconds of the match's start. He defeated Kinnikuman with a Back Flip. Kinnikuman lost but still wanted to challenge Jesse. Jesse was the only man to defeat Kamehame and since Kamehame saw promise in Kinnikuman, Kamehame decided to train Kinnikuman. He taught Kinnikuman the 48 Killer Techniques. When the training was finished, for now, Kinnikuman challenged and defeated Jesse.
Kamehame later joined Kinnikuman in the Dream Tag matches since Kinnikuman didn't have a partner. Kamehame sported a Kinniku mask and assumed the name Kinnikuman Great. The two had the name Muscle Brothers (マッスルブラザーズ).
The first match for them was against Pentagon and Black Hole: 4D Killer Combo. The 4D Killer Combo await in the first ring, and - as the Muscle Brothers enter - drop down upon them as a preemptive attack.  Kinnikuman ignores Kinnikuman Great's attempt to tag in, despite bleeding profusely, and this allows Black Hole to swap places with Pentagon. Black Hole throws Kinnikuman to the ropes; Kinnikuman Great reassures Kinnikuman they are equals, but Kinnikuman is determined to prove himself to what he considers his master. He still tags in Kinnikuman Great, despite his reservations, who uses a martial arts kick to attack Black Hole. They exchange several blows, but Kinnikuman Great temporarily incapacitates Black Hole with a Rolling Savate. 
The other teams leave their rings, so that they may watch the match.  Black Hole catches Kinnikuman Great off-guard and throws him to the ropes, in an attempt to engage in a German Suplex, but Kinnikuman Great counters with a Reverse Kick. Kinnikuman argues with Kinnikuman Great and trust breaks down, and this leads to the 4D Killer Combo gaining an advantage. As the 4D Combo use 4D Warp again, Great throws Kinnikuman out of the ring so that he may strike Pentagon midair. This fatigues both Pentagon and Great. 
Each move Kinnikuman uses on Black Hole becomes countered with Pentagon's Chronos Change, and - as Great comes to the defence - Pentagon uses Time Stop to freeze Great and stop with a Pile Driver. They stop Great with a 4D Cross and he is absorbed into Black Hole's body.  The 4D Combo tries to use a 4D Cross on Kinnikuman, but he counters with advice from the voice of Great.  Great tries to escape through Black Hole, grabbing his mask in the process, but Black Hole closes access to his dimension. 
Black Hole and Great fight within the dimension, and Great uses a Kinniku Buster to defeat Black Hole, while Kinnikuman uses the Kinniku Driver to defeat Pentagon. They combine their attacks into a Muscle Docking, which allows them to win the match. 
During a match between The New Machineguns and The Stray Devil Combo, Kamehame eventually was killed by Sunshine. Terryman carried Kamehame into an empty locker room and discovered Kinnikuman Great's identity. Before Kamehame died, he wanted Terryman to assume the mantle of Kinnikuman Great and his fighting techniques.
During the Royal Crown arc, Kamehame returned when Omegaman Dexia performed his Omega Metamorphesis technique and had Kamehame's spirit take over his body. Through the course of the match, Kamehame's spirit was too hard for Omegaman to control and Kamehame fully gained control of Omegaman's body. Kamehame used this to teach Kinnikuman his remaining techniques, the 52 Submissions. With the techniques at hand, Kinnikuman beat Omegaman with the Muscle Spark, and with his repertoire complete, was able to be a match for Super Phoenix.
