The Giant Eggman Robot is a towering humanoid mech. It possesses a head and a torso that come together in an egg-like shape, with its head section bearing a close resemblance to Dr. Robotnik's face. Notably, its head is gray with a red top section, round eyes and wide mouth section consisting of several square sections that serve as windows into the cockpit, black and pointy eyebrows, a pointy red nose, a red neckline, and triangular black flaps attached to the nose that resemble a mustache. ON its torso it possesses red plating covering the top of its chest and its sides, as well as its lower torso, with gray and black layers of metal right underneath them and between these sections. It also has thick gray shoulders with yellow plating covering them. The aforementioned shoulder plating in particular have red edges and two downward-pointing red arrow marks on each of them. The rest of its arms consists of black elbows, gray forearms with yellow collars with gray studs around their upper section, red forearm plating, and large red hands. Its legs on the other hand consist of gray thighs, thick and red lower legs with gray ankle collars, and large red feet. Also, on its back are what appears to be three rocket exhaust holes.
The insides of the Giant Eggman Robot consists mostly of gears, lights and circuits, with the exception of its head and torso, which share a large, spacious room with a gyroscopically stable platform inside it that reaches up to the height of the head. It also possesses several ledges along the insides of its torso, as well as a secondary seat for the co-pilot, which takes the form of a spherical cockpit positioned in the nose of the mech with an instrument board in front of it.
When powered by the Master Emerald, the Giant Eggman Robot's eyes and mount glow green. When running on auxiliary power however, its eyes and mouth glow red instead.
Features and traits
The Giant Eggman Robot is a machine of nearly unprecedented might. It is equipped with vast offensive capabilities that include missile launchers on its front torso that can unleash barrages of missiles, destructive and explosive lasers that it can fire from its eyes, nose and knuckles, wrist-mounted flamethrowers that can unleash torrents of enduring flames, and the "'Stache Smasher", a feature where the Giant Eggman Robot clamps its mustache panels together to crush anything caught between them. To match its size, the Giant Eggman Robot is tremendously durable: even when hit by its own missiles or Knuckles' strongest attack, the Giant Eggman Robot emerged from those scrapes without any damage. Its forearms are also equipped with collapsible rocket thrusters that it can use to increase the momentum of its punches. In addition, it carries a large infantry of green and gray-armored Badniks that it can deploy in swarms from its shoulders to attack smaller enemies. It is also capable of playing music, possessing a “world domination playlist” of songs to choose from. In exchange for all its power, however, the Giant Eggman Robot is a bit heavy and slow. It also comes with a computer for operating it via voice commands.
The Giant Eggman Robot is primarily powered by the Master Emerald. While the Master Emerald is infused with Dr. Robotnik, the Giant Eggman Robot acts as an extension of Robotnik himself while he resides insides its head, allowing Robotnik to control it with his thoughts and movements. He is also able to sense through the mech, such as when he felt Knuckles punching its fist. In the event that the Giant Eggman Robot loses the Master Emerald as its power source however, it can switch over to auxiliary power upon Robotnik's voice command. Furthermore, it can operated manually using the Robotnik Control Glove and the instrument pads on the platform inside its head. With the former in particular, the Giant Eggman Robot can mimic the arm movements of the Robotnik Control Glove's wielder. In return, the wielder can feel the pressure of the forces that the Giant Eggman Robot will come into contact with.
Sonic the Hedgehog 2
After gaining the power of the Master Emerald, Dr. Robotnik came to Green Hills where he took several Guardian Units of Nations tanks and helicopters, as well as trains and any other nearby technological device to form, in a black vortex of debris and green energy, the Giant Eggman Robot. Before the robot's completion, Robotnik pulled Agent Stone in with him as well, putting himself inside the Giant Eggman Robot's head with his power and placing Agent Stone inside its secondary cockpit as his co-pilot. While Robotnik and Stone listened to music inside the robot, the doctor made the robot stomp into Green Hills, forcing the G.U.N. personal to retreat. It was soon after confronted by Sonic and Miles "Tails" Prower in the Tornado, at which Robotnik ordered Stone to shoot them down with the Giant Eggman Robot's missile. Stone, however, did not have the time to read the instruction manual, so Robotnik launched the missiles himself from the secondary cockpit, inadvertently shocking Stone with his energy surges. Though the Giant Eggman Robot's missiles all missed the Tornado, one managed to catch Sonic. Knuckles then confronted the Giant Eggman Robot, prompting Robotnik to have its right hand collide with Knuckles. Though Knuckles managed to land a powerful punch on the hand, it did not damage it. Meanwhile, Tails used the gadgets he had installed into the Tornado to shoot at the Giant Eggman Robot, only for the robot to destroy the left side of the plane's wings and cause it to crash after using the 'Stache Smasher; Stone managed to make it do this after reading the Giant Eggman Robot's manual. Immediately after, Sonic returned the missile that was shot at him back at the Giant Eggman Robot, causing a collision that rattled it enough to knock Stone out. Robotnik then sent many of the Badniks onboard the Giant Eggman Robot after the trio, who had gathered on the main street, following it up with lasers that he shot out of the Giant Eggman Robot's knuckles.
Sonic later teased Robotnik to chase him, leading to Robotnik using the Giant Eggman Robot to run after Sonic. While this occurred, Tails flew Knuckles onto the robot without the doctor noticing. After the Giant Eggman Robot had chased Sonic into a nearby forest, where Robotnik explained to him his plan to conquer the multiverse, he began firing the Giant Eggman Robot's eye lasers at him. Eventually, Robotnik chased Sonic all the way to Green Hills' bridge, where he destroyed it with its nose lasers and caused Sonic to fall. With Sonic too injured to continue, Robotnik began gloat, only for then realize that Tails was entering the Giant Eggman Robot's cockpit. Tails proceeded to confuse Robotnik with holographic images of himself. While Robotnik was able to dispatch all the holograms, this distracted him long enough for Knuckles to get into position and punch the Master Emerald out of him. Due to this, the Giant Eggman Robot shut down and fell over, forcing Tails and Knuckles out of the mech with the Master Emerald. Picking himself back up, Robotnik had the Giant Eggman Robot run on auxiliary power so that he could catch Sonic and the Master Emerald. As the Giant Eggman Robot was about to step on Sonic however, Tom and Maddie managed to rescue Sonic and the Master Emerald by swopping by in a truck. This was short lived however, as Robotnik flipped the vehicle over with a punch from the Giant Eggman Robot. He then had it create a ring of fire around the trio and attempted to stomp on them with the Giant Eggman Robot's foot; however, this attack was stopped by Sonic when he transformed into Super Sonic with the power of the Chaos Emeralds that had been released from the broken Master Emerald. Super Sonic proceeded to tear off the Giant Eggman Robot's head, exposing Robotnik. As Robotnik tried to fake a truce with Super Sonic however, he used his Robotnik Control Glove to make the Giant Eggman Robot launch punches at Super Sonic, only for the hedgehog to stop the attacks easily and finish off the Giant Eggman Robot by piercing it multiple times in several places, before tipping it over with Robotnik onboard using a tap with his foot
After the toppling and destruction of the Giant Eggman Robot, G.U.N. would look through its wreckage for Robotnik, but could not find him in the debris. However, Stone had survived the Giant Eggman Robot's defeat and posed as one of the G.U.N. agents to evade capture and observe Commander Walters.
A playset by Jakks Pacific was produced which includes a toy of the robot, Green Hills' bridge and a 2.5" articulated figure of Super Sonic. The set seemingly uses early designs, as most notably the robot is primarily purple instead of red. A toy of the robot was also included in the line of McDonald's Happy Meal toys available during the promotion for the film.
- The Giant Eggman Robot is based on the Death Egg Robot from the Sonic the Hedgehog series.
- Despite being created from Robotnik's own thoughts, the Giant Eggman Robot possesses features not even he was aware of, including the Stache Smasher.
