Emporio Ivankov is queen of the Kamabakka Kingdom on Peachy Island in the Grand Line. He had eaten the Horm-Horm Fruit, a devil fruit that allows him to manipulate the hormones of the human body. He would go on to join the Revolutionary Army of Monkey D. Dragon as a general with Bartholomew Kuma. Ivan always seemed to notice that Dragon would out toward the East Blue, and suspected he might have family there, but he would never say. During one of their early missions into the East Blue on Dawn Island, they rescued a number of people from the great fire of Grey Terminal. At some point Ivan was captured for not cooperating with the World Government, along with Inazuma. They were sent to the great Marine prison Impel Down. Ivan escaped deeper into the prisons through secret tunnels that had been created by someone else before. There he randomly rescued more prisoners to create New Kama Land. The Impel Down guards presumed him to be dead, and he waited for news of Dragon's movements before trying to escape.
Emporio Ivankov is a supporting character of the One Piece series that was created by Eiichiro Oda. The series first began serialization in Shueisha's Weekly Shōnen Jump on August 4, 1997. He first appeared during the Impel Down Arc that began in Volume 54. Oda based Ivankov on the real life cross dresser Norio Imamura, who was a member of Mayumi Tanaka's acting group. Oda met him and described him as having the face of a boulder (岩, iwa) and he mistook Imamura's name as "Iwamura". Upon hearing that that Emporio was based upon him, he auditioned for the role as the voice actor and got it.
His first appearance was in One Piece Volume 55 CH. 537 "Okama in Hell", and his first anime appearance was in One Piece - Episode 438 "A Paradise in Hell! Impel Down Level 5.5! ". His character in the Japanese series was originally voiced by Norio Imamura, but after his arrest for indecent exposure he was replaced by Mitsuo Iwata, The English dubs produced by FUNimation has not yet announced a voice actor.
The design and personality of Ivan bears a remarkable resemblance to the Dr. Frank N. Furter character from the 1975 cult classic The Rocky Horror Picture Show that was portrayed by the acclaimed actor Tim Curry. Both characters have permed hair, wear revealing female lingerie, pearl necklace, heavy make up, are self proclaimed transvestites, proclaim the attributes of sexual ambiguity, and lead a band of like minded followers. Emporio's tendency to call his followers "Candies" is possibly a reference to the Rocky Horror song "Sweet Transvestite", In the lyrics, Frank N. Furter calls himself the "candy man".
Ivan and Inazuma spent years in Impel Down spiriting away many criminals into New Kama Land. While exploring the Frozen Hell of Level 4, Inazuma brought two people to Ivan. One was a Okama, such as himself; and the other was a young man. The young man was still awake. Despite being seriously infected with the poisons of Warden Magellan, he was pleading with Ivan to take care of the other man Bon Clay first. Ivan met with the young boy named Luffy and offered him the crew for the poison. There was a chance it wouldn't work, and if it did it would take ten years off his life. Luffy agreed without hesitation. Luffy was cured after several days of pain from the process, and woke to explain how he had broken into Impel Down to save his brother Ace. Ivan was read to let Luffy go on his own until Luffy let slip that he was the son of Dragon.Knowing he couldn't let his ally's son go off alone, he organized the people of New Kama Land to revolt.
Ivan with Luffy and Inazuma went down to Level 5 where Ace was being held. They were too late to save Ace from being taken away to Marineford, but Luffy was determined to follow him there. They gained two new allies, the former Shichibukai members Jimbei and Crocodile. The uprising began in Impel Down to make an escape. Ivan changed himself into a woman to defeat the guard Sadi-chan, then he changed back to buy Luffy and the others time as he fought against Magellan alone. Magellan won. He was left for dead, but Ivan cured himself with the Healing Hormones. He found Inazuma had also been poisoned. After curing him, he arrived just in time to launch everyone off Impel Down and to a Marine ship for escape. Bon Clay had stayed behind to open the Gates of Justice for them.
As they group of Luffy, Ivan, former Shichibukai, and other escaped convicts approached Marineford, Luffy accidentally let slip that not only wasn't Ace his brother by blood. Ace was the son of Gold Roger, the first Pirate King. The ship was caught up on a giant tsunami that froze with them on top. Below them the war between the Whitebeard Pirates and the Marines was in high gear. Ivan's group freed their ship and cashed into the harbor area. Ivan fought along with Luffy, and Whitebeard told his crew to back up the young man to save Ace from execution. It was a hard battle that forced Ivan to fight against Bartholomew Kuma, who didn't seem to recognize him.
Luffy fought hard but fell from exhaustion. He begged Ivan to give him another energy boost. Ivan once again used the Energy Hormones on him and they battled to reach Ace. Though Ace was freed, he was killed by Admiral Akainu in front of Luffy. Luffy went catatonic from the trauma, and it became a fight to protect the unconscious boy from Akainu. Ivan and Inazuma tried to shield his escape while Jimbei carried Luffy. Ivan's powers were useless against the magma powered admiral. He got to Jimbei and seriously injured both him and Luffy. Luffy was only rescued by the intervention of the Heart Pirates' captain Trafalgar Law. They escaped, and Ivan joined Boa Hancock, who was following after Luffy. Hancock and Ivan caught up with Law's crew. He had saved Luffy's life and they agreed he should be hidden on Hancock's island of Amazon Lily. Ivan parted ways with them there, and he returned to Peachy Island.
Upon his return, Ivan met a young man on Peachy Island named Sanji. he claimed he was a member of Luffy's crew, but Ivan refused to trust him. He had no idea if he was a Government agent after Luffy. Ivan presented Sanji with the wanted posters of Luffy's Straw Hat Pirates, but refused to admit any were of him. When he begrudgingly admitted that the awkward sketched poster was him, Ivan didn't think it looked much like him. Sanji tried to challenge Ivan for a ship to leave, but he was soundly defeated by Ivan's New Kama Kempo. When the papers arrived with news about Luffy's return to Impel Down, Sanji noticed a message there that he refused to explain.
While having a meal, Sanji was impressed by the power he felt from the food. Ivan explained this was the special Attack Cuisine of New Kama Kempo. He refused to give Sanji the recipes since he refused to join them. Ivan instead offered a challenge. Sanji could have the secrets if he could best all 99 New Kama Kempo masters. Though, the island's men would be constantly chasing him to try to put him in a dress. Sanji accepted this challenge and trained for two years on Peachy Island before he left to reunited with Luffy and the others on Sabaody Archipelago.
Ivan's greatest powers comes from the devil fruit he ate called the Horm-Horm Fuirt. The "home" is short for "hormone". With these abilities he can manipulate the various hormones of the human body. His finger tips can change into syringes then he can inject certain hormones into a target to effect a wide variety of changes.

He has even used this ability on himself to change into a woman. The reason is either based on his mood or for a different style of combat, such as when he fought Sadi-chan in Impel Down.
Emporio Healing Hormone: The healing hormones of Ivan can have some of the most serious side effects. When injected they manipulate the bodies hormones to cause a speedy healing effect, but the cost of this technique is that it takes away years from the life of the person it's used on. He's used it on Luffy to cure him of the poinson, then later on himself.
Emporio Energy Hormone: The energy hormones Ivan injects with this skill gives a massive burst of energy to the target. This can allow a person to move and be active in place of extreme exhaustion or injury. Though, this does not heal the body. It only causes the body to ignore the pain. Ivan used this technique several times on Luffy.
Emporio Facial Growth Synthesis: The facial grown hormones is a technique Ivan uses on himself. It causes his face to grow to a tremendous size. This can be effective in intimidation, and he uses it to enhance the attack potential of his Wink-based attacks.
The New Kama Kempo is a martial arts skill only taught by the New Kama Kempo masters of Peachy Island. They are boosted in strength by the special cooking style called Battle Cuisine. The philosophy is to build the body through the food to make them stronger.
