The Death Egg Robot is a massive grey mech with some red here and there. It has a small dome-shaped head that can open up like an eye. It also has three spike-like appendage on top of it that are similar to a crown. It also has a rounded body with a purple energy core in the middle and four tentacles with three-clawed hands at the end of each one on its back. It also has large shoulder pads with silver on its upper and lower arms and large fist with four fingers on both arms. Its lower body is also very serpent-like.
In the recent past, the Death Egg Robot was used by Dr. Eggman to battle Sonic the Hedgehog at the Eggman Empire Fortress. In the end though, Sonic and his allies defeated the villain and his mech.
- The Death Egg Robot is based on the vehicle of the same name that first appeared in Sonic the Hedgehog 2 as the final boss of the game. Its design, however, is derived from its Sonic Forces incarnation.
