Nerona Imu

Saint Imu of the Nerona Family was one of the twenty kings who founded the World Government after the Void Century 800 years ago. The person has been theorized by Emporio Ivankov to be the true identity of Imu, the secret occupant of the Empty Throne in the present day, them having achieved immortality through unknown means.

Abilities and Powers
As one of the twenty founders of the World Government, Imu ruled the world alongside the other royal family heads 800 years ago.

History
St. Imu of the Nerona Family was one of the First Twenty monarchs who eventually founded what today is known as the World Government.

Egghead Arc
On Mary Geoise, Imu shows himself whilst king Nefertari Cobra is still present, as the subject about the letter that queen Nefertari D. Lily sent back home picks their interest. The Five Elders shout Imu's name, claiming that Cobra was still present and he shan't sit on the throne next to him. An absurdly surprised king Cobra asks for the identity of the Empty Throne's seater, claiming that he already knows the name 'Imu' from among the First Twenty, albeit he believes that to be a coincidence. Uninterested, Imu tells him not to seek the answer, as they anyways won't provide it.

On Momoiro Island, after Sabo had finished explaining to Dragon and Ivankov what had occured during the latest Levely, Ivankov theorized that the mysterious Imu who seems to rule the World Government in secret is Nerona Imu, who could have been given eternal life. Ivankov noted that he could imagine no one else but one of the First Twenty to hold the power to outright order around the Five Elders, who are publically the World Government's heads as the highest-ranking Celestial Dragon.

Trivia

 * The book Ivankov uses to identify the possible connection between Imu and Saint Imu is titled "Genesis", likely a reference to the Book of Genesis, the first book of the Hebrew Bible and the Christian Old Testament, which details the creation of the universe by God.
