Death Egg Robot (Classic Sonic's world)

The Death Egg Robot (デスエッグロボ) is an object in the Sonic the Hedgehog series. It is another version of the Death Egg Robot from an alternate dimension set in the recent past. Like its counterpart, it is Dr. Eggman's personal mech.

Appearance
The classic depiction of the Death Egg Robot shows it as a humanoid mech whose head and torso come together in an indistinguishable egg shape. Its head and torso bare a great resemblance to Dr. Eggman, right down to his mustache and attire, but with a metallic grey scalp and a small antennas on the sides of its head. It also has yellow shoulders with red arrow marks on them, along with red and yellow arms with three spikes for fingers, a grey jetpack on the back, and thighs made of two grey spheres each. It also has large and armored red feet with kneecaps.

Modern depictions of the Death Egg Robot depict it as much taller than initially shown. While still similar to the original, its modern depiction has a sturdier chassis, what that appears to be wheels installed in the feet, round shoulders, and a black and grey jetpack consisting of two rectangular cylinders. The antennas seen on the head of the original are also absent and the forearms appear to have been redesigned to be much bulkier to allow for the rotary spikes on their ends. Its lower chassis is also smaller and its legs are shorter.

Powers and abilities
The Death Egg Robot is a massive powerhouse but incredibly slow. Its thick chassis made it nearly impervious to attacks (even bombs could only stun it temporarily) and it had enough physical strength to jump despite its massive frame and smash metal like paper. With its jetpack, it was capable of flight as well. It could also launch its hands telescopically and deploy small bombs. It is also shown to possess an articulated waist that lets it rotate its torso 360 degrees.

Past
The Death Egg Robot's early history was most likely largely the same as its mainstream counterpart's up until at least some time after the West Side Island incident.

Sonic Generations
In the console/PC version of Sonic Generations, Sonic went back in time and wound up fighting Dr. Eggman and the Death Egg Robot onboard the Death Egg during the time of the Westside Island incident. History would repeat itself though, with Sonic triumphing over the Death Egg Robot. It was then that the Time Eater showed up and kidnapped Dr. Eggman from the Death Egg Robot's remains.

After the Time Eater was neutralized, the Death Egg Robot most likely had its original fate restored.

Sonic Mania
In Sonic Mania, shortly after the incident on Angel Island, the Death Egg Robot was used by Dr. Eggman to ambush Sonic, Tails and Knuckles in the Green Hill Zone. Despite this, the heroes were able triumph over the Death Egg Robot, which fell into a hole upon its defeat, where Eggman was reunited with his Hard Boiled Heavies. Using the Death Egg Robot's still-functional arm, Eggman claimed the Phantom Ruby the HBH had found.
