Okama Kenpo is the fighting style used by Bentham. It is a style that uses mainly kicks and is taken directly from ballet dancing, therefore most of its stances are ballet poses rather than martial art stances. In a response to a fan, in order to learn Okama Kenpo, a person must do three steps: first a person must learn ballet, secondly they must learn karate, and third, they work at one of "those" places. Because of the complexity of the moves, Bentham can only use it with his own body which makes his Devil Fruit a liability. It is called Ballet Kenpo (バレエ拳法,Barē Kenpō?, literally meaning "Ballet Fist Way") in the Arabasta Arc in the anime.
Hakucho Arabesque (白鳥アラベスク,Hakuchō Arabesuku?, literally meaning "Swan Arabesque"): Bentham performs a powerful high kick, usually after a combination of kicks and punches. This attack is equal in power to Sanji's Mouton Shot. Arabesque is a raised-leg position in ballet. It is also called Swan Arabesque (白鳥アラベスク,Suwan Arabesuku?). This is called White Swan Arabesque in the Viz Manga, Ultimate Swan Arabesque in the FUNimation dub and Swan Dive in the 4Kids dub.
Okama Dash (オカマデャーッシュ,Ōkama Dasshu?, literally meaning "Crossdresser Dash"): Bentham taps the ground several times and then takes a giant leap forward. With his long legs, Bentham is able to cross long distances quickly. It is known as Swan Dash (スワンダッシュ,Suwan Dasshu?) in the anime and Viz Manga and Primadonna in the 4Kids dub but retains its original (anime) name in the FUNimation dub.
Chi to Ase to Namida Relevé (血と汗と涙のルルヴェ,Chi to Ase to Namida no Ruruve?, literally meaning "Tip-Toe Stance of Blood and Sweat and Tears"): Using his leg strength, Bentham is able to sprint up a vertical cliff wall.Relevé means "Standing on Tip-Toes". In the Viz Manga, this is called Relevé of Blood, Sweat and Tears and Relevé in the FUNimation dub.
Dozo Okamai Knuckle (どうぞオカマい拳,Dōzo Okamai Nakkuru?, literally meaning "Don't Mind My Fist"): Bentham simply punches the enemy in the face. The name is a pun off of the Japanese phrase "Dōzo okamai naku" (roughly "Don't mind me") and the English word "knuckle" or " Dōzo Okama Knuckle" meaning (Here is my crossdresser knuckle). In the Viz Manga, this is called Pardon My Oh Come My Way Knuckle.
Urabure Swan Butokai (うらぶれ白鳥舞踏会,Urabure Suwan Butōkai?, literally meaning "Shaking Swan Dance"): Bentham attacks the enemy with a flurry of kicks and punches. For some reason, Bentham's swans appear drunk and have their tongues hanging out when he uses this attack. This prepares Bentham for Swan Arabesque. This is called Drunken Swan Soiree in the Viz Manga and FUNimation subs, Degenerate Swan Dance Recital in the FUNimation dub, and Smiling Swan Soiree in the 4Kids dub.
Okama Chop (オカマチョップ,Okama Choppu?, literally meaning "Crossdresser Chop"): Bentham strikes the enemy in the eyes with a chop, blinding them. This attack can prepare Bentham for Keri Pointe. Unlike other attacks, this one can be made by Benthan transformed as Nami, implying it is a very simple technique with little to no practice required to perform. This is known as Ballet Chop in the anime and FUNimation dub, Karate Chop in the 4Kids dub, Swan Chop in the Viz Manga, and Crossdresser Chop in the FUNimation dub of Movie 8.
Keri Pointe (蹴爪先,Keri Poanto?, literally meaning "Kick Claw First Pointe"): After blinding the enemy with Okama Chop, Bentham jumps into the air and kicks the enemy in the face with both feet. He continues to push the enemy until he kicks them off into a nearby structure. This is literally translated as Kick Pointe in the Viz Manga and FUNimation dub and called Tip-Toe Kick in the 4Kids dub.
Mascara Boomerang (マスカラブーメラン,Masukara Būmeran?): Bentham peels off his mascara and throws it at the enemy, and, like an actual boomerang, it returns to his hand. The mascara is bladed so it cuts the enemy, and can hit the enemy upon return.
Grand Fouetté: Ano Natsu no Hi no Memoir (グラン鞭打 あの夏の日の回想録,Guran Fuette Ano Natsu no Hi no Memowāru?, literally meaning "Grand Whipping: Memories of That Summer Day"): After spinning 320,000 times, Bentham performs a kick using the momentum of the spins to increase the strength. The true power of the kick was not seen because Sanji was able to dodge and counter it. In the Pirate Warriors series, Bentham flies forward while rapidly kicking then ends with a powerful kick. This is called Memoir of that Summer Day in the Viz Manga, Memoirs of a Summer's Day in the FUNimation dub and Spinning Summer Pirouette in the 4Kids dub.
Prima (主役技,Purima?, literally meaning "Leading Part Skill"): Bentham removes the two swans from his shoulders and places them on his feet. When he kicks in prima mode, the swan neck extends, giving him further reach, and the steel bill pierces the enemy. When he kicked a stone wall, it left a solid hole without any cracks around it. According to Bentham, the power of his kicks when upgraded with Prima is equal to a rifle shot. Not relevant to the attack, the swan on his right foot is female, the Pen, and the swan on his left foot is male, the Cob.Prima is the ballet term for the lead performance, hence the particular kanji symbols written for this technique. In the 8th movie, they are more whip like. In the Viz Manga, this is called Prima Ballerina and in the FUNimation dub, it is called The Prima of Balet Kenpo.
Bombardier (爆撃白鳥,Bonbarudie?, literally meaning "Bombing Swan"): After using Prima, Bentham kicks the enemy with an extended and pointed kick. Before delivering the real kick, Bentham appears to kick several times, which may be used to confuse the enemy.Bombardier is French for bomber. This attack is called Swan Bombardier in the Viz Manga and 4Kids dub and Bombardier in the FUNimation dub.
Ano Fuyu no Sora no Memoir (あの冬の空の回想録,Ano Fuyu no Sora no Memowāru?, literally meaning "Memories of That Winter Sky"): After using Prima, Bentham leaps into the air and begins to perform several somersaults in mid-air. After spinning enough times, Bentham descends at a 45 degree angle and delivers a piercing kick strengthened by the momentum of the spins. The full power of this attack was not seen the first time because Sanji dodged and countered it. He used a version without his swans against Minotaurus in Impel Down. It caused significant damage, and was even capable of knocking it down, but was not enough to defeat it. This is called Winter Wonderland Jete in the Viz Manga and 4Kids dub and Memoirs of a Winter Sky in the FUNimation dub.
Bombardier Arabesque (爆弾白鳥アラベスク,Bonbarudie Arabesuku?, literally meaning "Bombing Swan Arabesque"): This is the strongest attack Bentham uses. After using Prima, Bentham uses Bombardier after leaping into the air. The kick is also higher than the normal Bombardier. This attack is called Swan Bombardier Dive in the Viz Manga and 4Kids dub but retains its original name in the FUNimation dub.
Ohikae Na Fouetté (お控え・ナ・鞭打,Ohikae na Fuette?, literally meaning "Oh! Pardon My Whiplashing Feet"): Bentham lunges forward and does a backwards somersault in midair, to land a powerful kick on the opponent's head. This attack was strong enough to ram Minotaurus into a jail cell's bars, but not enough to slow him down.Fouetté is a ballet term for a whipping movement of one leg, made while turning on the other leg. In the Viz Manga and FUNimation subs, this is called Wait Just A Fouetté.
Anime Only Techniques
Ano Sabaku no Kuni no Memoir (あの砂漠の国の回想録,Ano Sabaku no Kuni no Memowāru?, literally meaning "Memories of That Desert Country"): An anime-only technique, Bentham leaps into the air and spins twice before ramming the tip of a foot downwards in a punishing kick. He uses this technique to destroy Impel Down's controls for their local Gate of Justice. This move refers to Arabasta. In the FUNimation subs, this is called Memoirs of a Desert Kingdom.
So far two different styles of Okama Kenpo have been seen, regular Okama and Newkama.
Both versions have a unique attack that involve the use of mascara or eyelashes.
So far, Bentham is the only person shown using Okama Kenpo.
