Imperator Ix

"I have been imprisoned in the Twilight Cage for too long! Soon I will break free and shake the foundation of the universe!"

- Pir'Oth Ix, Sonic Chronicles: The Dark Brotherhood

Imperator Pir'Oth Ix (ノウェム) is the main antagonist of Sonic Chronicles: The Dark Brotherhood. He is the leader of an ancient tribe of echidnas known as the Nocturnus Clan. A megalomaniacal echidna with a knack for techno-wizardry and machiavellian politics, Ix orchestrates the capture of all seven Chaos Emeralds and the Master Emerald, in a scheme to break the Nocturnus Clan out of the Twilight Cage, and to conquer Sonic's world.

History
Ix has ruled the Nocturnus Clan echidnas "for as long as we can remember" (according to Shade in Chapter 6). Four thousand years ago, when the Nocturnus still lived on Sonic's world, it was Ix who incited the tribe to war against Knuckles' ancestors, the Knuckles Clan. Bloody warfare against Chief Pachacamac's warriors only ended when the Perfect Chaos cataclysm (recounted in Sonic Adventure) destroyed the Knuckles Clan, leaving Ix and the Nocturnus with no further obstacles on the road to complete conquest of the ancient world.

However, the Nocturnus Clan eventually fell victim to its own supernatural catastrophe: the Argus Event. Without warning or explanation, the entire civilization was uprooted from Sonic's world and cast into the Twilight Cage; a slow-time prison-dimension occupied by a host of fearsome alien races. Forced to adapt or die, Ix continued to lead the Nocturnus in the Cage's nightmaric environments, brokering strategic alliances and pitting his enemies against one another, as the Nocturnus society evolved in mere years from an ancient-era tribal civilization to a sinister technological empire. The echidnas were eventually able to subjugate or pacify their caged opponents, and turned their attentions to escape.

At the start of Sonic Chronicles, Ix dispatches Procurator Shade and a large force of Nocturnus soldiers back to Sonic's world using the warp belt technology developed by the Nocturnus inside the Cage. The Imperator himself later comes to Angel Island, to personally capture the Master Emerald. After fighting Sonic and Knuckles to a standstill (and declaring Shade an insubordinate traitor), Ix uses the Master Emerald to open a wormhole, and retreats to the Twilight Cage with the Emeralds to prepare his invasion.

During the second half of the game, Sonic pursues Ix into the Cage and marshals the other imprisoned races against the Nocturnus. After the heroes fight their way to the throne room of the Nocturne citadel, defeating all guards present, Ix attempts to convince Knuckles to side with the Nocturnus echidnas - but to no avail. After fighting three consecutive battles, the Imperator remains unbroken. He uses either the Chaos Emeralds or the Master Emerald (the game is unclear on this point, as he even says that he's "using the very power of Nocturne itself!") to achieve his Super State. But after being defeated by Super Sonic, Ix still won't go down; and he teleports away as the Nocturne begins to fall apart. His eventual fate after The Dark Brotherhood is unknown.

Personality
Ix is extremely arrogant, considering those below him as "dust" or "worms", but has no qualms with getting his hands dirty if the situation necessitates it. Prolonged isolation in the Twilight Cage has driven him insane, instilling within him a desire to conquer Sonic's world instead of merely returning to it. As the unquestioned leader of the Nocturnus, Ix demands complete loyalty from all his soldiers, swiftly punishing those who dare to so much as question him, such as Shade.

Abilities
The following is a list of POW moves Ix has in Sonic Chronicles: The Dark Brotherhood:
 * Doom Orb (Dark Gravity ダークグラビティ): Ix shoots a green energy ball that, if not perfectly avoided, instantly KOs one member of the team.
 * Power Blast: Ix shoots a green energy beam from his scepter.
 * Dark Anomaly: A move similar to Chaos Rift.
 * Overload: Only used move as Imperial Ix, a higher-powered version of Dark Anomaly.

Archie Comics
Pir'Oth Ix appears in the Archie Comics' Sonic the Hedgehog comic book series and spin-offs. In the comics, Ix is the leader of the Nocturnus Clan, the advanced sciences caste of a group of echidna colonists from Albion. They settled in Soumerca, where Ix and the Nocturnus Clan remained behind and entered a territorial war against the Felidae and the Knuckles Clan, until Ix and his people were mysteriously trapped in the Twilight Cage. Inside this prison, Ix and the Nocturnus Clan managed to counquer the other alien race there and took over the entire dimension. Ix is currently researching the Twilight Cage to find the means of returning to Mobius and conquer it.

Trivia

 * Although it is never mentioned in Sonic Chronicles: The Dark Brotherhood, Ix's first name, "Pir'Oth", is given in the title of his character information box on the game's official website, along with other trivia not directly referenced in Chronicles.
 * Ix's design is reminiscant of two other white-furred, technophilic echidnas from alternative Sonic continuities: Doctor Finitevus, from the Archie Comics, and Doctor Zachary, from Fleetway's Sonic the Comic. In fact, Ix may have been influenced by these characters, just as Shade may have been influenced by Julie-Su.
 * Ix's hair style is similar to that of Silver the Hedgehog, though Silver's hair has five points where Ix only has three. The rings on Ix's wrists also bear a resemblance to Silver's.
 * There is a possibility that Ix is in fact, insane. As stated by Shade that he "has gone mad from his years in the Twilight Cage." The fact that he's insane could connect back to Dr. Finitevus from Archie, who is also insane; but he went insane from too much Chaos energy.
 * Unlike other members of the Nocturnus Clan, Ix does not disappear in a flash of light when he is KO'ed.
