Egg Beater

The Egg Beater is a battle mech that was created by Dr. Eggman and was designed to counter all of Sonic's abilities, first being used during the attack on Knothole and later on New Mobotropolis. It had managed to utterly defeat Sonic, however it was destroyed by the combined efforts of the Knothole Freedom Fighters and Chaotix. Despite it's destruction however, Eggman plans to bring back his creation in a more powerful state.

Appearance
The Egg Beater takes a rathe bulky appearance, having a round body and had spikes on it's shoulders, the top of it's head, and on it's feet. It's head has a sort of red-metal mustache that mimics Dr. Eggman's and a blue visor. It sports two missile launchers on it's back, while also wielding a checkered wrecking ball with it's right hand and a star bumper shield with it's left, wrist-mounted laser blasters being on both wrists. The mech primarily sports red and black in it's color scheme, with yellow and grey acting as secondary accents.

Abilities
The Egg Beater was specifically designed to combat Sonic the Hedgehog and was able to counter all of his abilities. It was able to fire teleportation beams at its desired target to teleport them to another location (such as the Egg Vineyard), and was able to fly with very powerful propulsion jets on the bottom of its feet. Apart from using its wrecking ball and shield to bash it's opponents with, the mech also came equipped with two missile launchers on its back and laser emitters on its forearms. Its shield is extremely durable, as it was able to tank Sonic's most powerful spin dash with only a dent to it.

Background Information

 * The Egg Beater combines elements of several boss machines from the Sonic video games: its wrecking ball is borrowed from a recurring boss first seen in the original game, the missile barrage may possibly be a reference to a boss in Sonic The Hedgehog 3, while its shield and foot design both seem lifted from the first boss of Sonic CD. Its general form also resembles the final boss in the classic game: Sonic The Hedgehog 2.
 * The Egg Beater also shares a strong resemblance to Metal Robotnik from the Sonic OVA movie.
