The Gizoids (ギゾイド Gizoido?) is a group that appears in Sonic Chronicles: The Dark Brotherhood. It is a mass-produced line of combat androids created 4,000 years ago by the Nocturnus Clan as advanced infantry in their wars of conquest. Following the Argus Event however, the entire Gizoid line was trapped within the Twilight Cage along with the Nocturnus Clan, excluding a single specimen, Emerl. Nearly 4,000 years later, Emerl was found by chance by Gerald Robotnik and was given the title "Gizoid" due to being the only known Gizoid model on the planet.


Not much is known about the Gizoid line. Emerl was discovered to be the last remaining robot.

The Gizoid robots were developed by the Nocturnus Clan as artificial soldiers around four thousand years prior to Sonic's time, as Imperator Ix's people vied for control of the ancient world against Chief Pachacamac and the Knuckles Clan. Marching out of the factories within the Nocturne citadel, the prototype Gizoids fought at the forefront of the Nocturnus armies, and (according to Ix's hyperbole before the final boss in The Dark Brotherhood) turned the tide of the war against Knuckles' ancestors. Gizoid's strength lay in their ability to flawlessly mimic their enemies' attacks, allowing them to become more skilled in combat with every vanquished opponent.

After Perfect Chaos obliterated their rival brethren, the Nocturnus Clan enjoyed a free (if brief) reign over Sonic's world. Robotics research and development did not stop during this time; the pinnacle of Gizoid science in the ancient world came in the form of Emerl, a robot with the ability to absorb Chaos Emeralds. As Nestor the Wise theorized, it was precisely this breakthrough development which attracted the attention of Argus, and led to imprisonment of the Nocturnus echidnas in the Twilight Cage. Rightly or wrongly, the Nocturnus were removed from Sonic's world shortly after Emerl's creation.

Excluding Emerl, every single Gizoid under Nocturnus control was transferred to the Twilight Cage in the Argus Event, along with the Nocturne and (apparently) most - if not all - of Nocturnus civilization. Some artifacts apparently remained, and the Nocturnus were dubbed "The Fourth Great Civilization." Imperator Ix continued to use the robots as the echidnas subjugated the other races of the Twilight Cage, and advanced Gizoid models remain a central part of the Nocturnus army when Sonic and friends arrive there during Chapter 7 of Sonic Chronicles: The Dark Brotherhood.

List of Gizoid models[]


  • Gizoid - The basic combat robot employed by the Nocturnus army throughout the Twilight Cage in Sonic Chronicles: The Dark Brotherhood. Has 250HP and can use any and all Nocturnus and player-character POW moves.
  • Gizoid Mk. II - A slightly stronger version of the basic Gizoid, with 340HP.
  • Gizoid Centurion - Advanced Gizoids that ambush Knuckles and Shade's party on the Nocturne. Gizoid Centurions have a protective, starry shield around them which renders the robots totally impervious to attacks. Only Tails' quick thinking enables the heroes to disable their shields, using a specific sonic frequency.
  • Gizoid Guardians - Elite bodyguards of Imperator Ix, only seen during the final boss fight of Sonic Chronicles: The Dark Brotherhood. These robots have a single, wide wheel in place of their feet, and attack using a massive pole-arm and a signature POW move, 'Crippling Arc'.
  • Prefect Charyb - One of the two Gizoid Prefects of the Nocturnus army. Charyb fights Sonic and Tails in an underwater lair as a sub-boss for the Nocturne.
  • Prefect Scylla - The other Gizoid Prefect of the echidna armed forces. Scylla is somewhat mentally unstable, and will often laugh crazily at the end of his sentences. Scylla fights Knuckles and Shade as another sub-boss on the Nocturne.
  • Emerl - Said to be the strongest Gizoid ever created by the Nocturnus Clan.

In other media[]

Books and comics[]

Archie Comics[]

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the Gizoids were a line of super-robots created by the Nocturnus Clan. Incredibly adaptive with an advanced artificial intelligence and capabilities equal to an entire army, the Nocturnus Clan would fall back on their Gizoid army when their own personal tech failed.


  • In Sonic Battle, Gerald's diary reveals that gizoid is a term in an ancient language for everything. This refers to the Gizoids' ability to copy and adapt to everything.
