The Egg Gunner is a humanoid combat robot created by Dr. Eggman. These machines serve as the doctor's primary foot soldiers in Sonic the Hedgehog (2006). They have a nimble, almost skeletal physique with thin framework. Their legs have backward knee joints and three claw-like toes. The torso is covered in a simple armour plate with a floodlight attached on the left side. The head is small and saucer-shaped with a horizontal optic visor. The gunner has no hands, only weapons. The left arm is fitted with a machine gun and the right one carries a grenade launcher that fires small, slow-moving mini-rockets. The Gunners are also flight-capable and have jet boosters that fold away into their backs.
The Egg Gunner has three variants that are identified by their different colours and weapons.
