Omega Arm (オメガアーム Omegaāmu?) is a Power Formation maneuvers and the Wide Power Attack used by Team Dark in Sonic Heroes. When using this technique, E-123 Omega launches different rounds of artillery from his built-in arm cannons in all directions, with the effects depending on Omega's level.


When performing Omega Arm, Omega releases his teammates from his grip (due to holding them for the move's initial attacks) and stands in one place while spinning his robotic torso around clockwise. While doing so, Omega unleashes a full-force weapon barrage from his built-in arm cannons, which he transforms according to the weapon he uses. This results in a spiral-like wave of artillery that damages anything caught within its radius.

By collecting red Power Cores during gameplay, the player can increase the power, nature, and radius of the Omega Arm. The levels of power are as follows:

  • Level 1: Omega reconfigures his claws into rotary cannons and fires a hail of bullets in a circular radius around him.
  • Level 2: Omega reconfigures his claws into Flamethrowers, spraying flames in a circular radius around him. Attack radius is increased about a couple of meters and the resulting damage dealt is doubled.
  • Level 3: Omega reconfigures his claws into Missile Launchers, and unleashes a barrage of drill-like missiles in a wide circular arc that create explosions upon contact with nearby enemies or obstacles. Attack radius and damage is at maximum. The missiles fire at a slightly upward angle so that they may not hit ground enemies from a far distance.

To perform this technique in gameplay, the player must have Team Dark in Power Formation and must have performed the Spinning Back punch. Right after using the Spinning Back punch, the player then has to press XboxX.png/PSSquareButton.png/SNNBGAMECUBEDISCO.png to use the Omega Arm.
