Eggrobos or Egg Robos (エッグロボ, Eggrobo) are enemies from the Sonic games.
Eggrobos are android badniks built by Dr. Eggman, in his own likeliness. They first appeared in Sonic & Knuckles, as the sole enemy in Sky Sanctuary Zone. After being sent out of the Death Egg, they will hover in place and attack the player character when in proximity, firing at them with their large laser pistol. In the same game, an Eggrobo piloting Dr. Eggman's boss machines is the antagonist in Knuckles' story, replacing Dr. Eggman and acting identically to him. Their design in Smash Run is directly based on their appearance in Sonic Generations, where they reprised their role as Sky Sanctuary's enemies. Other important appearances include an Eggrobo being an unlockable character in Sonic R, and a group of five modified Eggrobos, known as the Hard-Boiled Heavies, which appear as bosses throughout Sonic Mania.
Eggrobos appear as enemies. They hover in the air keeping their distance from the player, and are hard to hit directly. They attack by shooting energy projectiles: either an energy bullet which can be reflected and absorbed, or a thin and continuous beam.
