- Not to be confused with the Egg Buster, a version of the Egg Flyer found in Sonic the Hedgehog (2006).
The Egg Busters are a variant of the more common Egg Gunner robot, painted yellow instead of white. This model is equipped with a homing missile launcher on each arm, along with a propulsion unit mounted on its back. It attacks by firing powerful homing missiles that leave an explosion upon impact, which can hurt the player if they are near the explosion's blast zone. The missiles can be picked up by Silver's psychokinesis. It has strong armor, taking three hits to be destroyed. Due to the game's rushed development, their missiles will reduce the FPS of the game when launched, causing the game to slow down and making it more difficult to dodge or grab the missiles using PK.
- They are the only version of Eggman's robots that were not given any name or description in the Sonic the Hedgehog: Official Game Guide.
