Emperor Dominius

Emperor Dominius, more commonly called Duros Black or Dark Duros, was the God-Emperor of Planet Duros until his death. He sought to build a superweapon capable of destroying entire planets in order to become the most powerful being in the universe.

Appearance
Duros Black is a very large man who wears a large silver lion mask and a full suit of highly adorned, obsidian black armor with a purple glow. However, upon closer inspection the lion mask appears to be a wolf. He also carries a giant sword. Under his mask, he looks exactly like Duros, but more menacing. He has white hair and pale skin with purple shadows under his eyes, presumably at least partially due to the influence of his armor. In his final moments however, he looked like an old and weakened version of Duros.

Personality
Duros Black is an evil man, imposing slavery over the planet of Duros and randomly killing people as 'examples'. This is primarily because he was corrupted by his armor, as once the armor was removed, he returned to his normal, wholesome self.

Overview
Duros Black is a very powerful fighter, being massive in size and strong enough to wear full plate armor all the time. He also has the many benefits of wearing the cursed armor, such as eternal youth, great defense, and an extra mouth. In terms of combat, everything Duros can do, Duros Black can do better. Despite seeing Ragnar being trained in Armament Haki, and having one of his own Inquisitor's know Armament Haki, namely Maximus, and having over a thousand years of training, Duros Black still does not appear to have access to Armament Haki.

As the Emperor of Duros, Duros Black has complete authority over every living citizen on the planet and wields absolute executive, legislative and judicial power. He commands a massive army, the true numbers of which are unknown, as well as the four Inquisitors, who serve him as his highest ranking administrative and military officials.

Cursed Armor
This set of cursed armor gave Duros Black eternal youth, at least while he's wearing it. It appears that the armor uses life force as a fuel, as when Duros Black is about to absorb energy he claims that the armor "needs more energy"


 * Destruction Wave (Proposed: Hakai-hadō) - Using the boots' magic, Duros Black can stomp on the ground and send out a strong shockwave.
 * Armor Manipulation - Duros Black can contort his armor to eat various things. Eating people will slowly drain their life force, which directly feeds into Duros Black's own lifespan, which is what allowed him to live for 1000 years.
 * Force Gauntlets - Using these gauntlets allows Duros Black to grab foes from a distance by utilizing some unknown telekinetic force.

The Inquisitors
The four Inquisitors are the public representatives of Emperor Dominius, each ruling one of the four major cities of the planet in his name.

Devil's Luck Pirates
Due to the influence of the cursed armor, Duros Black betrayed and killed the Devil's Luck crew of his own timeline. He then quickly developed a sick obsession with them, spending years trying and failing to create clones of them in order to kill them again and again to satisfy that obsession. When he found out about the arrival of the current timeline's version of the Crew, he was delighted over the prospect of getting to kill them again.

Luna
Originally one of his Inquisitors, a loyal and powerful subordinate, Luna rebelled against her lord after realizing how much damage his policies were inflicting on the population of the planet. She went from worshipping and serving Dominius to despising him, quickly becoming determined to bring him down. This resolve was strengthened even further when her half-brother Helios fell in battle against the Emperor, prompting her to decide to become the new Empress of Duros in order to change the world for the better and honor his memory. The Emperor didn't seem to mind Luna's betrayal, as even though she was a highly capable Inquisitor, he could presumably replace her quite easily.

Helios
Helios was a Centurion in Dominius' army, serving him with great enthusiasm and a peerless sense of duty. However, after the Devil's Luck Pirates manage to make him see the truth of Dominius and his tyranny he joins them in their rebellion. Dominius took to this betrayal with apathy and casually killed him.

Lyssa
The Emperor seems to be mostly unaware of Lyssa's existence. However, she blames him for the deaths of her parents and harbors an intense hatred for him.

History
Duros Black is the corrupted, alternate timeline version of Duros who found all the pieces of the cursed armor. This Duros (also called Duros Black or Dark Duros) got corrupted by the armor and killed all of the Crew, except for Louis who in his last dying breaths sent Duros Black back in the past hundreds, maybe even a thousand years. Once he landed there, Duros Black took the early people of Planet Duros and manipulated them into thinking of him as a god. Once he established himself as a god, Duros Black created imitations of the Crew to kill in an attempt to quell his anger. However, he's now quite happy that he can truly kill his crew once again. He enjoyed their fight, and when all hope seemed lost for the Crew, with Pearl raging as a dragon, Gravy and Louis eaten by the armor, and Helios dead, the Louis who sent Duros Black in time showed up and saved Gravy and his past self, along with turning Pearl to her normal self. After this, Duros used Pearl's fire to destroy the evil armor. Soon after this, Duros Black was sorry for everything he did, but was happy he could protect his planet before he turned to dust.

Trivia

 * Dominius bears many similarities to the Emperor of Mankind in Warhammer 40K.
 * He often likes to pick a random person to kill as an example to not disobey him and sometimes for no reason at all. Two of them happen to be Lyssa's parents.
 * Despite wanting to kill his former crew again and spending effort to recreate them his Inquisitors share similarity's to his former crew. For example, Ragnar and Maximus being the physically strongest of their respected groups shows that he gathered them as he could trust their reliability from previous experience.
 * Duros Black has done the most damage in one turn, being 121, without a critical hit
 * It can be assumed Black Duros also hates mimes since mimes were outlawed on Planet Duros
 * When Duros Black betrayed the Devil's Luck Pirates in his original timeline, the first member he killed was Pearl since he deemed her full dragon form to be the biggest threat to him.
 * Interestingly enough, when he was eventually finally defeated, it was technically by the flames of Pearl's dragon form, stored and released at him by Duros' shield.
