Eggrobos are humanoid Badniks that have made a number of appearances throughout the Sonic the Hedgehog franchise. They first appeared in Sonic & Knuckles and are modelled after Dr. Eggman himself. They are equipped with jet packs for flight and they are armed with laser cannons that can fire straight shots or burst shots. In Sonic Generations, there are black Eggrobos that can launch homing missiles from their heads.
Eggrobos have also appeared in the Archie Sonic the Hedgehog series and in the UK-published Sonic the Comic. In StC, Eggrobos had camera optics that fed live images straight to Dr. Robotnik's command centre on the Death Egg. Some Eggrobos have even been equipped with cloaking devices to become invisible.
In the Archie Sonic series, the Eggbots were not created by Robotnik, but by his nephew Snively. They hatched from large egg-like capsules and were equipped with various tools as well as their standard armaments.
