Di-Jun Huang

Teikun Ō was the president of Zheng Fa. Despite his fearsome appearance, he was in actuality a coward who pretended to be the man he claimed to be. He came to visit Japan to give a speech thanking Miles Edgeworth and others for their efforts in exposing the leader of an international smuggling ring that had crippled his country's economy. During his speech, his discourse seemed to touch the hearts of others. However, his speech was cut short when he was unexpectedly injured.

The real president

 * Main article: SS-5 Incident

{C Years ago, an assassin called Ryōken Hōinbō was hired by the president's double due to the fact he was jealous of his position and that he gained no genuine respect. The real Ō was at the Happy Family waiting for Ami Aizawa, who he didn't know had left hours ago. When Hōinbō arrived, Ō begged him to wait until he could see his son. Hōinbō attacked him, with the first attempt missed him and the real Teikun Ō was killed the next attempt. He was then replaced by his double and his accomplices, Marī Miwa and Bansai Ichiyanagi took his corpse.

The group were planning to betray and kill Hōinbō but Sōta Sarushiro informed Hōinbō of the betrayal. Sarushiro then planned to kill his best friend Manosuke Naitō and the fake president because the fake president was part of the group that tried to kill Sarushiro's savior.

Speech

 * Main article: Turnabout Target

On March 25, 2019, the fake president's private plane landed on the waters of Gourd Lake. Ō then exited the plane onto an already set-up podium, and then, attended by several bodyguards including Manosuke Naitō and Gai Tojiro, proceeded to address an eagerly waiting crowd. Since he didn't trust the local police, he hired a private security firm. Sometime later, however, while Ō was giving his speech, a gun fired a shot, injuring Ō, creating panic within the crowd as the bodyguards scrambled into action. He was escorted into the plane and into the room, where he cowardly hid under the bed.

The investigation
After the perimeter was secured by the bodyguards, he was taken into the plane and the genius prosecutor Miles Edgeworth was called upon the scene to investigate. He appears after De Killer entered the plane with Edgeworth and co. and left once he was sastified with the investigation. He introduces himself to Edgeworth but immediately tried to hand over investigative authority to the Zheng Fa police and had Naitō confisicate the evidence. Edgeworth was forced to commence Logic Chess against him. When Edgeworth's Knight destroys his, he reveals that he wishes to apply extraterritoriality rights to his plane. However, he was beaten when he slipped up about the used gun being from outside, which the extraterritoriality rights do not apply to.

Ō then testified about the speech, saying that a round red balloon had burst from the gunshot he had heard and that when his two bodyguards attempted to escort him to the plane, a second gunshot had hit Tojiro. The red balloon that had burst was the Steel Samurai balloon and Ō would have known that wasn't a round red balloon if he was present during the speech. He then claimed it was the flag flapping wildly blocking his field of vision but this proved that his bodyguard was the one who shot the flag and the balloon. He then breaks down, revealing his true self: a cowardly, gluttenous man. It was then revealed the whole assassination attempt was a farce to make him more appealing to the public since his popularity was starting to decline.

At the end of the case, Ō turned back into his kinglike persona and thanked Edgeworth for his efforts in solving the case and exposing his most trusted bodyguard as a murderer. He reveals back when he proposed the idea of a fake assassination on him to Naitō, he was anxious and that gave Naitō the impetus for murder. Edgeworth reminds him that he was the one who came up with the fake assassination in the first place so he had to take responsibilty for his crime. Ō agrees with Edgeworth and before he left, he thanked Edgeworth one more time and told him he would always be welcome to Zheng Fa if he decided to visit.

Death

 * Main article: The Grand Turnabout

Unlike in the previous case, this time he died for real. He was killed by Sōta Sarushiro when they accidentaly met on the rooftop of the Prosecutorial Investigation Committee Headquarters on April 5th. His body was hidden in the freezing room of the warehouses rented by the Berry Big Circus near the Sunshine Coliseum. When Sarushiro then transported it back using his balloon to frame the judge Hakari Mikagami, he noticed the torn off Borumosu head in the Global Studios filming lot and decided to dump the body there, to make it look like he was crushed underneath it, thereby framing Shimon Aizawa who had been rehearsing there the night before.

In the investigation, it was finally revealed that the real president died and that the current one was just a body double. The actual reason why he returned was because he found out about Aizawa being Ō's biological son. Fearing that the test results would reveal the conspiracy, he came to kill both Aizawa and Mikagami. The real Ō's skeleton was found in Bansai Ichiyanagi's house.

Personality
At first, Ō appears to be a bold and authoritative ruler who pushes his weight around and likes giving dramatic speeches. However, underneath it all, he is a scaredy-cat who can only pretend to be the lion his people need.

Design
{C Ō is a large, lionlike, muscular man who wears a tight-fitting purple suit with an orange tie. His long hair, which points behind him, along with his long and shaggy beard come together to resemble a lion's mane. The design is meant to feature a more muscular and powerful look than that of fellow Zheng Fa native Shi-Long Lang.

Name

 * His Japanese surname "Ō" (王) means "king" and given name "Teikun" (帝君) means "emperor, monarch", a fitting term for the President of Zheng Fa.
 * His name also fits with the "chess" theme of characters in this case, with him being the "King" while Naitō is the "Knight" and Tojiro is the "Rook".
