Egg Gunner

Egg Gunner is an enemy in Sonic the Hedgehog (2006), being the game's most common enemy. It is a white robot, with a propulsion system that allows it to hover, it also has a machine gun mounted to the left arm, and a missile launcher to the right. It has blue lights for eyes. It also has three other variants, the Egg Lancer, Egg Stinger, and Egg Launcher.

Sonic the Hedgehog (2006)
The Egg Gunners make their first appearance in Sonic the Hedgehog (2006). They first appear in the opening cutscene, attacking Elise in Soleanna with their machine guns until Sonic arrives and destroys them. They also appear in every action stage after that (along with most of the cutscenes for Sonic's story). They are white robots with black metal, red eyes, they also have a machine gun on their left arms, and a rocket launcher on the right. They are most often on the ground, but sometimes use their hover ability.

Sega Superstars Tennis
They reappear again in Sega Superstars Tennis. They have a minor role in the game, and they play very few times. They are seen alongside Metal Sonic in the game. Instead of guns and missiles, they are armed with electric spiked balls that relieve their opponents of ten rings when the balls strike.

Trivia

 * The strategy guide for Sonic the Hedgehog (2006) states that the gunners have two machine guns for arms. This is incorrect, as they have one machine gun and the other arm is a missile launcher.
 * The Gunners appear in two games, but all other versions only appear in Sonic the Hedgehog (2006).
 * The Egg Gunner family bears a striking resemblence to the E-100 series, albeit more streamlined and realistic. The Egg Gunner in particular most resembles E-102 Gamma, due to the single mounted gun on the right hand.
