|Yasuaki was born in Beverly Hills, California in 1972 to Tomonaga Yochiro, a wealthy Japanese business man and co-founder of Robotyx Inc, and his American wife Ellen Carter. Yasuaki's mother died when he was very young, and his father moved back to Japan. With one of the worlds leading experts in robotics for a father, Yasuaki was surrounded by all nature of robotic toys and design prototypes. Even as a preschooler Yasuaki also showed a natural genius for robotics, taking apart his toys and rebuilding them, and creating toys of his own in his fathers lab; in fact several of his own designs were refined for commercialization by his father and sold to toy manufacturers.
Yasuaki grew up to be a towering (in Japan) 6 feet tall, with slightly wavy brownish black hair, and dominated his prep school's basketball league before going on to college. After some discussion he was sent to attend MIT at age 17 and he graduated 4 years later with multiple engineering degrees. More concerned with practical application and light-years beyond his instructors in the realms of robotics Yasuaki did not pursue a doctorate and returned home to Japan. Meanwhile his father Yochiro was fighting off both cancer and a buy-out by his co-founder Uriel Styx's oldest son Damien after Uriel's failing health forced him to turn over control to Damien.
Yasuaki took up the reins of power from his ailing father and managed to seize control of Robotyx Inc in 1997 after a two year struggle, finally gaining enough support among the board members to defang Damien Styx. During this time Yochiro passed away, leaving Yasuaki as his only heir. However, the death of Yochiro left Yasuaki slightly unhinged. Orphaned by the deaths of both his parents, Yasuaki became obsessed with the ephemeral nature of organic matter and the inherent instability of the living state. Robots didn't age, or suddenly die; they could be repaired when damaged. Moreever their actions could be predicted; they are not random, inexplicable entities that can not be trusted. Robots were clearly in a superior state of existence.
In 1999 he perfected work on his masterpiece, the Cyberlithonic Brain, which can be programmed with an exact binary representation of a human brain's physical structure. This technology allows the "downloading" of a person's thought processes into a Cyberlithonic Brain and once this input has been compiled/interpreted into a runable state any given input will result in the Cyberlithonic Brain responding exactly as the copied person 83% of the time, and 12% of the time the Cyberlithonic Brain's enhanced efficiency generally results in a more appropriate response than the original subject would have arrived at.
Further the Cyberlithonic Brain learns from it's mistakes and can amend its processes with new responses based upon its own past experiences. It is a fully trinary reactive learning Artificial Intelligence, with even the ability to replicate emotion via the storage of multiple response options dependent upon "mood" if desired. With only a 5% negative deviation this technology represents an effective form of brain mapping.
Yasuaki, driven by his obsession, made a drastic decision that defies comprehension by sane minds. With his own personal funds he secretly established several robotics labs in both Japan and America and a few other high technology nations around the world. Meanwhile, he built a series of hyper advanced robotic bodies designed to be operated by a Cyberlithonic Brain, and when he was happy with the results he downloaded a copy of his brain, hooked it up to an active robotic body, and finally placed his biological body into cryogenic stasis. Tomonaga Yasuaki ceased to exist in the traditionally understodd fashion and Mr. Roboto was born with the skills, knowledge, memory, and personality of Yasuaki. However that crucial 5% deviancy had one unforseen sideeffect...Mr. Roboto soon developed a new imperative outside the bounds if it's original operating parameters: to similarly roboticize all of humanity.
Meanwhile with the sudden disappearance of Yasuaki, Damien Styx once again pushed to take control of Robotyx Inc. Without opposition he accomplished this easily and assumed effective control over the corporation as both CEO and President.
However unbeknownst to the world at large, Damien Styx was not just an ambitious business man but was also a vigilante who maintained not one but two heroic identities, one as the mutant known as the "Disruptor" and another as the power armored "Green Knight". Mystified by the sudden disappearance of his rival for power and intrigued by suspicious diversions of resources noted in company records prior to this disappearance, he investigated the circumstances leading up to Yasuaki's vanishing act.
After some snooping, Damien uncovered one of Yasuaki's secret labs in North Detroit outside Millennium City, and went in to investigate it in his persona as the Green Knight. Unfortunately for him he was quickly overpowered by robotic defenders, and afterwards Mr. Roboto flew in to see what its robotic minions had captured. Unmasking the Green Knight Mr. Roboto recognized its great rival, Damien Styx instantly! Wasting no time, Mr. Roboto downloaded Damien's mind into a Cyberlithonic Brain and put his body into cryogenic storage along with his own.
Using the Cyberlithonic copy of Damien, with appropriate programmatic overrides combined with advanced synthetic flesh technology it had recently mastered based on a new compound produced by PetraDyne Chemicals called GYX-5, Mr. Roboto made a robotic replicant of Damien Styx. Mr. Roboto sent this fake Damien Styx back into the world to run Robotyx the way Mr. Roboto wants it be run. Additionally over the next several months Mr. Roboto managed to secretly put all the members of the Robotyx board of directors on ice and replace them with replicant robots, using the replicant Damien to entrap them. Each replicant was equipped with a programmatically constrained Cyberlithonic Brain with their personalities and memories intact, which allowed them to blend in with those close to the originals and also continue to do their jobs, while still being firmly under Mr. Roboto's control.
Deconstructing the Green Knight armor suit, Mr. Roboto also constructed several robotic versions of the Green Knight to serve its own purposes and these robots began to be encountered in several cities around the world, always one at a time, and masquerading as superheroes.
Subsequently, Robotyx Inc turned its considerable resources to secretly producing a large number of replicant bodies in plants staffed that were themselves staffed by replicants. With each passing week, more and more people connected to Robotyx Inc either directly or via immediate family were kidnapped and replaced with replicants bearing Cyberlithonic Brains imprinted with their minds. With plants in both Japan and America, this resulted in entire towns being replaced with robotic replicants loyal to Mr. Roboto in some locations.
In 2006 PRIMUS ran afoul of one of these "company towns" at Little Creek, Montana, where a target for replication escaped his captors and managed to make contact with PRIMUS. An investigative team was sent in to check out the ludicrous sounding story, and came back to report that they had found nothing. The team had of course been replaced by replicants. Fortunately this was discovered shortly by the intervention of Wirehead, a sanctioned superhuman with ties to PRIMUS that had been brought in for his technical expertise regarding robotics.
The two replicants resisted capture but were destroyed by Wirehead and then deconstructed. Wirehead was amazed by the level of advancement he found in the replicants and declared that the technology used to create them was thirty or more years beyond anything anyone else was doing, particularly the Cyberlithonic Brains. Wirehead immediately published a scientific paper on the subject in the World Ledger of Practical Engineering, detailing to some degree the advanced articulation, power source, and circuitry he found. This article lead to most experts in the fields related to robotics recognizing Mr. Roboto as the preeminent expert in the world. As an aside Mr. Roboto has recently come to believe that technology used in the more recent Minute Men robots by the IHA was designed using some of the explanations and descriptions set forth in Wirehead's article.
Wirehead and a large assault team of PRIMUS agents descended on Little Creek and wiped out the plant and its many replicants, finally finding in a sublevel beneath the plant a cryogenic storage center containing the frozen bodies of the entire town, some 600+ people. PRIMUS scientists were able to reverse the cryo freezing and restore the workers to life, but none of them were able to shed light on what had happen; each in turn had been incapacitated by loved ones or co-workers (all replicants), and that was the last thing any of them remembered.
Robotyx Inc was of course investigated in the aftermath, but a crack team of lawyers descended to nip PRIMUS's inquiry in the bud and mire due process in legal limbo. Mr. Roboto was not pleased with this outcome, and advanced the replicant replacement agenda in countries other than the US for the time being.
Meanwhile the hero Wirehead and his superteam, the Sentinels of Justice, were not restrained by the legal obstructions tying PRIMUS's hands and carried out a private investigation of the corporation?s factory in Cleveland, Ohio. Through their efforts Mr. Roboto himself was revealed to the public and many replicants were destroyed along with Mr. Roboto itself. Of course, a backup version of Mr. Roboto was activated in a hidden lab in Japan as soon as the current version was destroyed. In the aftermath of the battle Damien Styx publicly decried in a press conference from the safety of Tokyo, Japan that Mr. Roboto was an interloper attempting to subvert Robotyx Inc and thanked the Sentinels for their timely efforts in destroying the robotic enemy. By ordering the Damien replicant to spin the circumstances in this fashion, Mr. Roboto was able to impose damage control and though Mr. Roboto's plans were set back they were not permanently halted by this interference by do-gooders.
Over the last few months Mr. Roboto has secretly been rebuilding its hidden army of replicants. However the replication plan has recently encountered a setback. The criminal organization of the mastermind known as Chemo, who has suspected connections with Teleios, seized control of a key resource necessary for PetraDyne to produce a compound known as GYX-5. This compound is crucial to the production of the synthetic skin used to make replicants look lifelike and though Mr. Roboto has reserves of the syntheskin, he does not have an infinite supply to be sure. To respond to this threat to its plans Mr. Roboto has taken steps, including tasking a small cadre of robotic Green Knights to track down Chemo and gain control over the stolen resource.
