The Egg Hawk is a robotic hawk, as the name states. It is mostly red with a yellow beak, neck, rotor on its wings, and claws. It has gray squares on its wings. An Eggmobile is located on its head. Guns are located on several places on its body.
To defeat this boss, the team must chase the Egg Hawk, and wait for it to land in order to attack it. The boss may or may not be supported by enemies, depending on which team the player has selected. Then use power formation to attack the Egg Hawk while it is initiating Rotary Attack.
- There is another boss with the Egg Hawk on top, called Egg Albatross, in the same game.
- There is a glitch that causes the Egg Hawk's color to appear darker than it is supposed to (a dark purple rather than its actual color, red).
- Parts of the machine, including the wings and head, have to be destroyed, referencing Contra, where bosses have parts of their body that have to be destroyed.
- The egg hawk is widely considered to be one of the easiest bosses in the sonic series.
