Egg Fighter

The Egg Fighter (エッグファイター) is the main model of the robots that appear in Sonic Unleashed. It could wield a buzz-saw sword, normal shield, an electric shield, a spring shield, or nothing at all. Each has a variety of attacks, depending on the variation.

Egg Shooters look like the Egg Fighters, but their body has a different color and they can shoot lasers. Egg Launchers also resemble Egg Fighters, but they fire missiles at Sonic.

Egg Fighters are accompanied by some powerful robots, such as the Aero-Chasers, which are robots with jet packs and lasers, and finally the Interceptor, a huge robot that flew and dogged Sonic through many stages.

Egg Fighter also returns as an enemy for the Rooftop Run stages and missions in Sonic Generations.

Trivia

 * In Act 1 of Windmill Isle day (and the DLC version of that level) the Egg Fighters have a reddish orange color scheme unlike their usual steel color. Strangely, these Egg Fighters will not attack you no matter what.
 * The Egg Fighter's appearance looks very similar to Arms, a Badnik that appeared in Adventures of Sonic the Hedgehog and Dr. Robotnik's Mean Bean Machine.
 * The hands of the Egg Fighters are the Little Fighters, who have autonomous AI which allows them to fight after they are dismembered from the rest of the body. They are rarely seen in in-game levels, but are more notable as the controllers of the Egg Devil Ray and Egg Lancer's pilots.
 * In Eggmanland, an Egg Fighter Knight variation with an electric shield appears only once.
