Legion ex Machina

The Legion Ex Machina are the most recurring antagonists in the cartoon Big Guy & Rusty the Boy Robot. The group consists of seven members, most of whom are identical. Despite having the same appearances each member has a different cybernetic modification. There is a member left who hasn't been revealed.

Birth
The Legion Ex Machina was invented by Dr. Roland Poindexter. His goal was to create what he perceived as the perfect artificially intelligent robots. He was successful but that was also his downfall. His creations soon turned against him. They placed Poindexter in stasis where they had complete access to his mind. The legion then built a secret base and began their goal to eradicate mankind.

ARG0-12
ARGO-12 was the first robot created by the Legion Ex Machina. It's purpose was to recruit any other robots to join the legion. It would terminate any of them if they refused the offer. It was powered by packs of nuclear energy that #6 stole from where he worked. ARGO-12 engaged in a fight with the Big Guy and was almost successful. It ran low on fuel and was given a defective nuclear pack from Rusty which resulted in a massive overload. ARGO-12 was scrapped afterward.

Rebellion

 * 1) 6 (also known as Dr. Gilder) was placed inside Quark Industries as a mole to gather information. He still felt human emotions which his peers considered a weakness. He harbored bitter feelings toward the CEO, Quark Donovan, for destroying his inventions. Gilder eventually lost his patience and shifted his focus towards killing Donovan. His first attempt was to hack a robot but it was stopped by the Big Guy. He then hacked into Rusty and controlled the boy as an assassin. However, he was stopped when one of Quark's scientists, Dr. Slade, discovered what he was doing. She dispatched security but he literally threw them aside. Dr. Gilder chased her to a grinder and lost his skin in the process, revealing he was a robot. Big Guy and Rusty reached Slade in time. Dr.Gilder fell into the grinder. The Legion Ex Machina took no pity in the demise of their colleague.

ARGO-12000
ARGO-12000 was the legion's second robot creation. It was a 400ft version of ARGO-12. ARGO-12000 was sent to steal a Micro-Fusion generator that could be used to build more robots like it. The body parts of ARGO-12000 were transported through an underground rail station. The remaining piece, the left hand, was salvaged before construction was complete. This didn't stop the robot from stealing the micro-fusion generator which was successful. ARGO-12000 headed towards the nearest ocean but was shot by a green beam from its missing hand. It collapsed and went permanently offline. The generator was recovered.

Stealing Rusty's Brain
The legion devised a machine to sabotage a dam. However, this was also an attempt to download Rusty's brain.

Project NOVA
In order to finish their latest creation, the Legion Ex Machina needed specialized fuel. Their only source was a power plant that manufactured neutrinos. They sent a machine to steal a new kind of neutrinos: anti tronic neutrinos. As it began draining the entire supply it was interrupted by the Big Guy. Rusty then attempted to download data from the machine's archives. #4 attempted to use his own strength to counteract Rusty. Both sides engaged in a mental tug-of-war. The connection ended after Rusty and #4 were overwhelmed. Later, it was revealed that their personalities swapped. Rusty started building Project NOVA and #4 played video games. When Quark and the Legion Ex Machina found out, more confrontations followed. Rusty completed NOVA and released it. Dr. Slade tried to contain Rusty while Big Guy attempted to stop NOVA. Rusty managed to escape his confines but so did #4. When they reached the scene, each of them engaged in another mental tug-of-war. That time, there was a swap between their identities. Rusty took full control of #4's body. He then short circuited NOVA. The brain of #4 was acquired by Quark.

Confronting Big Guy
Sometime later, the legion sent it's fifth member to acquire a robot from technology collectors. He was greeted by the Big Guy upon his arrival. A fight took place where #5 had his cybernetic modification as an advantage. His skin was destroyed after he revealed himself as a robot. He still had the upper hand in the battle. Big Guy used his own body to smash #5 into the ground. #5 malfunctioned from the impact and was then shot into a tank of cryogenic ice. His existence came to an end when Rusty shattered his frozen body.

Missing Colleague
Quark still had the brain of #4. Donovan's nephew, Pierre, stole it for his science project. He placed the brain inside a toy robot. Once activated, the toy robot escaped. Unaware of the Legion Ex Machina, Pierre had no idea about the possible consequences. Meanwhile, the legion made plans to destroy #4 because he became incompetent. He contacted them and requested a rescue but was unaware of their true intention.

Sabotaged Rusties
The remaining three members of the Legion Ex Machina purchased a household version of Rusty from Quark industries. Using their advanced technology, they redesigned the circuitry. Then they connected the robot into a machine and used it to control every other household version. Their mission was to head directly towards Quark, take over, and replace their own batteries with nuclear packs. The next phase of their mission was to shoot green beams at New Tronic City. This would annihilate the inhabitants and allow the Legion Ex Machina the opportunity to build a utopia for robots. They were almost successful but a bomb destroyed all of the Rusties.

Fake Big Guy
Frustrated by their constant defeats, the Legion Ex Machina built an exact duplicate of the Big Guy. They dubbed it the BGY-11X. In order to hide the real Big Guy, the legion trapped him in a remote desert. During its time at Quark Industries the Legion learned the truth: the Big Guy was piloted by a human. Despite the efforts of the BGY-11X to act like its counterpart, Rusty became suspicious and found out. When he told Dr. Slade she was already being pursued. The BGY-11X caught her in an elevator and threw her out of a building. She was saved from death but Rusty became the next target. The real Big Guy appeared after his pilot and body were found. Both the original and the clone engaged in a brutal fight. The Big Guy won by shooting his arm into the cannon of his opponent.

Abduction
The victory was short lived however. The legion dispatched a clone of the pilot, Lt. Dwayne Hunter. It shot the lieutenant unconscious and sent him directly to the legion's headquarters. Hunter and the legion met face-to-face.

#7
The current status and location of #7 is unknown.
