Pir'Oth Ix's Super State[2] (本気ノウェム Honki Nowemu?, lit. "Serious Novem"), also known as Imperator Ix Final Form,[3] Twilight Ix,[4] or simply Imperator Ix in-game, is the Super State of Ix and the final boss in Sonic Chronicles: The Dark Brotherhood. He attained this form using the residual Chaos Emerald energy from the Chaos Emeralds and/or Master Emerald in Nocturne.


Casting away his battle outfit, Imperator Ix fights in his casual attire in his Super State. His spines grow further than in his original form, so that they look like Knuckles' dreadlocks. His fur color is the same as his normal form (white and gray) and his eyes are blanked out, possibly glowing. He is constantly surrounded by a cyan aura.


In battle, IX has "???? HP" (9999 HP) stat, and his only move is Overload. He can be defeated in one turn if the player can successfully perform Super Sonic, making this one of the most simple final boss fights in the series. However, if the player unsuccessfully performs all the real-time events on the touch screen, Ix will regenerate HP. When fighting him, it is impossible to ambush or be ambushed, because neither Ix nor Super Sonic have normal attacks to use.

  • So far, Ix is the second villain in the video game continuity to achieve a Super State through use of the Master Emerald, the first being Mecha Sonic in Sonic & Knuckles, although he is the first organic villain to do this.
    • It is unclear if Ix used the Master Emerald to transform as Sonic remarked, "If he can use the power of the Emeralds, then so can I!", but Ix states just before the transformation that he is using "the very power of Nocturne itself!". However, this might refer to the fact that Nocturne was using the power of the Master Emerald to move out of the Twilight Cage, and when calling upon the power of Nocturne, Ix might have absorbed the residual energy from the Master Emerald in Nocturne in order to induce an actual super transformation.
  • For unknown reasons (most likely development issues), this form's mugshots are used for Imperator Ix's mugshots in all instances of the game save for when he is on his Power Throne in Nocturne, including when the player encounters him in his base form on Angel Island.
  • Ix in this state overall appears similar to Nestor.
