The first individual Bugster to be born, Parado's genesis lay in Mighty Action C, a demo game created by the teenage Kuroto Dan, son of then Genm Corp. CEO Masamune Dan. The Bugster Virus, which had been discovered by Kuroto on his laptop shortly following the arrival of the New Year in 2000 having appeared as a result of the Y2K bug, was planted on the Mighty Action C disc by Kuroto in an act of spite against eight year old Emu Hojo, whose fan designs he had sent in impressed yet angered Kuroto, who recognized the boy's vision as rivaling his own. Receiving Mighty Action C as "thanks" from Kuroto, the young Emu was unknowingly infected with the Bugster virus and, through his subconscious wish for a friend to play games with, the being who would be known as Parado manifested within him. Unknown to everyone but Kuroto Dan, Parado's conception inside Emu influenced him into becoming the Genius Gamer, "M."

As M, Parado would use Emu's body and play and win various championships, defeating a new challenger who named herself "Genius Gamer N" as a homage to him. After this challenge, Emu was abducted and operated on by Michihiko Zaizen and Parado was separated from Emu's body. This resulted in Emu returning back to his goal of becoming a doctor.

Despite being separated, Emu was still infected with Parado's Bugster Virus. This allowed Emu to transform using a Gashat without a "compatibility surgery." The side effects of being able to transform without it was that it would stimulate the Parado's Bugster Virus within Emu, causing Emu to evoke mannerisms similar to when he and Parado were one by switching from (Boku) into (Ore). In return, some of Emu's personality traits would eventually be evoked within Parado as well, as would later be seen.

Parado is seen playing a portable version of the Mighty Action X game and is informed by Graphite of a new Bugster infection by Graphite. With Graphite proclaiming that they would soon be joined by an influx of comrades, Parado voiced to him his excitement at the prospect of their game field expanding.

As Graphite spread the Bugster virus further, Parado voiced to him that fate was like a puzzle game. When asked by Graphite if he was sure that they should not be acting directly, Parado decided that he might as well introduce himself as he set off.

Meeting Graphite's old nemesis, Taiga Hanaya, Parado called off Graphite from his confrontation. Before they took their leave, Parado dared Taiga to clear the most games and become the strongest Kamen Rider.

With the Rider War heating up Kuroto, Lexx, Emu, Kiyra, and Dr. King retreat to Kurotos estate for food and to finds tools to turn the tide, as the ar is a danger to human and Bugster alike Parad joins, revealing his Ruse t othe team that he is the Mighty Action Bugster and learning that each Game can only have one Bugster meaning that he has to be from something other then Mighty Action X as Salty is already the Bugster of that game. As Emu, Kuroto, and Lexx get distracted inside Monster Safari however Parad starts to search the estate and with no one watching him he finds 3 new gashats Kuroto is working on and spawns 3 new allies from them gaining the services of Eve, Blake, and Micheal.
