Professor Gerald Robotnik

Gerald Robotnik (ジェラルド・ロボトニック, Jerarudo Robotonikku) or Professor Gerald (プロフェッサー・ジェラルド, Purofessā Jerarudo) was the grandfather of Doctor Eggman Robotnik and Maria Robotnik. Professor Gerald is the creator of Shadow the Hedgehog, Space Colony ARK, the Biolizard, Artificial Chaos, and various other projects while in charge of Project Shadow. He was also noted as "one of the greatest scientific geniuses of all time" by Eggman.

Professor Gerald loved his granddaughter, Maria Robotnik, dearly and was working a project that would allow human life to be immortal and would never age, with Maria chosen for the project, until G.U.N. came. Maria was killed ("taken away" in the English dub) by G.U.N. soldiers while assisting Shadow in escaping from them and Gerald himself was incarcerated by the government and sentenced to execution, spending his last days formulating his plan of vengeance against humanity.

Gerald has somewhat similar appearences that he shares with his grandson, de crazy old mamEggman, but somewhat older. He is bald with a gray mustache, his eyes have not been seen they were obscured by his glasses, and wears a lab coat, purple turtleneck sweater, dark brown pants, and pince-nez blue glasses. His height 170 cm. (5 ft. 7 in.), weight is 88 kg. (191111999999995lbs.)



Before his descend into insanity, Gerald was a good man and a profound humanitarian, the very much opposite of his psychotic grandson Eggman. He was devoted to using his great intellect to help mankind and bring people happiness and hope through the power of science, and believed this was the reason for his existence. His devotion to humanity is so great that he, after discovering Black Doom's plans of destroying humanity, creatcmaocmwoamkaowmxpalxmwpap!a?cowmaocmwoed the Eclipse Cannon as means to destroy Black Doom and his alien race and protect the world from outside threats and entrusted his will of protecting humanity to Shadow (this is revealed once Shadow confronted Black Doom and listened to Gerald's recorded message to him while being incapacitated by Black Doom). He was also much more serious about his work than Eggman.[1]vmaowmcmcoamam

Gerald was a man of strong ethical standards. He refused to use his genius for the wrong reasons, initially dismissing to lead Project Shadow because he believed it was crossing the limits of man to obtain immortality, and he had no interest in making or giving weapons for war.[4][8] However, he was not above breaking his own standards for certain reasons, like being forced to by the higher-ups or when he thought it was for the greater good such as participating in Project Shadow or handing over the dangerous Emerl to find a cure for her dying granddaughter. Even when in such situations however, Gerald would go out of his way to make sure the products of his research would have the capability for good as well, like when he gave both Shadow and Emerl feelings so they could choose not to fight and when he planned to share Shadow with the world to help mankind. He also held the strong belief that power born from the desire to protect rather than the desire to conquer would make all conflicts cease to exist.[19]

When Maria was killed, Gerald went through a profound change as he was consumed by grief and went insane. He eventually became a rage-filled psychopath, developing a deep hatred for humanity who he blamed for Maria's death and became obsessed with getting revenge at everyone by committing global genocide. Even in his last moments, all Gerald had to express was his contempt at humanity.


Friends and AlliesEdit




The Space Colony ARKEdit

Main article: Space Colony ARK

The former home of Gerald, Maria, the commander of G.U.N., and various researchers and soldiers, the ARK was a gigantic space colony where great research was performed. The entire place also worked as a life support system. While Gerald focused on making inventions for the good of mankind (such as the Heal Unit), little known devices of mass destruction were being made (The Ultimate Life form and the Eclipse Cannon), mostly under the influence of and preparing against Black Doom. Others who lived aboard the ARK were Shadow (who protected the ARK from danger until it was shut down), the Biolizard and Emerl (until he was transported to G.U.N's fortress). When Shadow failed to protect the ARK from an inside attack, the ARK was shut down. Many was capturd imprisoned and taken away (including Maria) and Gerald himself went insane. The ARK was later rediscovered by Dr. Eggman, who used it as a temporary base. After this, it seems GUN took control over the ARK once again.

Eclipse CannonEdit

Main article: Eclipse Cannon

The Eclipse Cannon is an extremely powerful weapon that is located inside the "nose" of the Space Colony ARK (the ARK resembles Gerald's face). It is powered by Chaos Emeralds, and can destroy planets or even stars with all seven. Gerald built it to destroy the Black Arms when they arrived near Earth, but after he went insane, he reprogrammed it to send the ARK flying into the Earth the next time it was activated with all seven Emera FOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOODlds. Eventually, it was used for its original purpose.

Artificial ChaosEdit

Main article: Artificial Chaos

Artificial Chaos are Gerald's first noteworthy creations. They resemble Chaos and are most likely modeled after him as Maria states that Gerald created them based on "a god of an ancient culture". The Artificial Chaos are made up of a core (the head, shaped like that of Chaos 0) and trillions of nanobots that both protect the core and provide the body for it. While the early Artificial Chaos seen, they had red, half-closed eyes and red marking on their heads, the final Artificial Chaos have larger green eyes and an emblem on their foreheads.

When first created they began acting out and attacking the ARK (according to Gerald, they had their electrode conductors reversed), but GUN (and possibly Shadow), stopped them. They were later fixed, and then adopted by the government to protect the ARK. When the Black Arms invade the ARK, Doom's Eye calls the Artificial Chaos "the legacy of Gerald" and then announced that they belonged to the Black Arms now, suggesting that the aliens somehow took control of them. There are several types of Artificial Chaos that are listed below.

Artificial Chaos P-1Edit

These Artificial Chaos, which are believed to be the first prototype of the series (hence the name), are tall, stationary, and are able to pull their head into its body to protect itself. They had the ability to cling to any surface and attacked using either a laser built into its eyes, long tentacle-like extensions from its body, or a combination of both.

Float Type Artificial ChaosEdit

These Artificial Chaos would float in midair with its water-part shaped as a large sphere. It either waits for someone to come within range, or floats toward them in the air. They attack with the same tentacles and lasers as the normal one.

Artificial Chaos P-100Edit

This type of Artificial Chaos, which are believed to be the final prototype for the Artificial Chaos line (hence their name), have the ability to split up the nanobots that make up its body into dozens of smaller robots called "Cells". This, however, left the head open to attack and easy to destroy. When the head was destroyed, all the Cells that it spawned would self-destruct. These are also believed to be the version that Shadow destroyed when they ran amok on the ARK, though they acted a bit different, as they attacked with tentacles and only split up when damaged. They can also grow to immense sizes, possibly by fusing with each other (several GUN soldiers suggest this during the attack).

Artificial Chaos CellEdit

When the Artificial Chaos P-100 splits its body up, the pieces turn into small blob-like cyborgs that are referred to as its "cells". The cells would crawl on the ground and try to surround an enemy, at which point they would start to self-destruct, or they would emerge from the body of the P-100 when struck, would float around the body for a few seconds, and then re-merge with the head. The cells would all be destroyed when the head is taken out.

Project: GizoidEdit

Main article: Emeral

Project: Gizoid was Gerald's experiments with the ancient robotic being known as the Gizoid. Gerald discovered that the robot could mimic anything it saw, and that it was powered up by Chaos Emeralds. Gerald soon had to hand the Gizoid over to the impatient government in order to buy time for research on his Project: Shadow. After the government did their own experiments with the Gizoid, it went crazy and destroyed a large part of the ARK, leading the government to deem Gerald's experiments as a threat to humanity and shutting down Project: Shadow and the ARK itself.

Project: ShadowEdit

Main article: Project Shadow

Project: Shadow was Gerald's project to create the Ultimate Life form, a being that would be immortal and would never age (this was probably related to the needing for the survival of Maria, who was suffering from a terminal illness). The project was successful, but was deemed too dangerous by the government, who sent G.U.N. to shut it down.


Main article: Biolizard

Biolizard was the prototype to the Ultimate Life form. It was a giant lizard hooked up to a life support system. The Biolizard was deemed a failure as it went out of control and had to be sealed up. After Gerald went insane, he programmed the Biolizard to stop anyone from hindering the ARK crashing into the Earth, but it was destroyed by the combined efforts of Super Sonic and Super Shadow.

Shadow the HedgehogEdit

Main article: Shadow the Hedgehog

Perhaps Gerald's most brilliant achievement, this was the finished result of Project Shadow, the immortal Ultimate Life form who would never age. Shadow was created after Gerald formed an alliance with the alien leader Black Doom, using his DNA to create Shadow with a promise that Shadow would help Black Doom retrieve the Chaos Emeralds 50 years later. However, Project: Shadow was forcibly shut down after Shadow was created, and Shadow was ejected to the planet by Maria during the raid. However, he was eventually found, captured and hidden away by GUN, only to be released 50 years later by Gerald's grandson Eggman.

Heal UnitsEdit

Portable box-like devices that send out energy that replenish health and are still used to this day by GUN. The Heal Unit may have inspired the creation of the Heal Cannon, a Bazooka-like weapon that fires shots with the same healing capabilities. Maria Robotnik feels it is Gerald's greatest creation (next to Shadow of course, most likely due to the fact that she is a pacifist).

Bomb UnitsEdit

The Bomb units produce an unlimited supply of bombs, these are used in the game Shadow The Hedgehog to break walls and find secret passage ways. Their design is very simalar to the Heal Units design.



Gereald being sentenced to execution

Fifty years before the main series, he attempted to create the "Ultimate Life Form" under the funding of the United Federation, hoping that it would help Maria (in case something would happen to her). He failed various times until meeting with the alien, Black Doom, and forming an alliance with him. Black Doom provided Gerald a sample of his DNA to use to create Shadow and Gerald promised Doom in return that he would give him the Chaos Emeralds by using Shadow as an agent who would collect the Chaos Emeralds without question. At some point after successfully creating Shadow, he learned of Black Doom's true plan (to destroy the planet) and prepared the ARK to act against Black Doom when the time comes. He also prepared a video for Shadow to see when the time came explaining Shadow's origins, as well as his intention for Shadow to make up for Gerald's past mistake by collecting all the Chaos Emeralds and then using his creation, the Eclipse Cannon to destroy the Black Comet. Later, G.U.N. decided Gerald's experiments were dangerous to humanity, and boarded the ARK to shut them down, capturing and imprisoning all the collegues, even killing Maria ("taking her away" in the English dub) in the process. This caused Gerald to lose his grip on reality, so he created plans to have the ARK crash into the planet with such power that it would completely destroy it. He was then captured by the government and executed (but not before leaving behind a recorded videotape of the execution where he explains in his final words his plan to get revenge on Earth). And he also used his diary as the acting bait for his assistance to reawaken Shadow (who would go along his orders without question) in case someone happens to find it. However, Rouge suspected that deep down, Gerald may have wanted Shadow to stop his plan from the beginning.
