Bugsters

This article is about a monster race in Kamen Rider Ex-Aid.

The Bugsters (バグスター, Bagusutā), are a type of computer virus and the main antagonists of Kamen Rider Ex-Aid.

Overview[]

The Bugster virus (バグスターウイルス, Bagusutā Uirusu) is a computer virus that has gained the ability to infect human beings. After infection, the virus initially lies dormant within the host's bodies during an incubation period. When the host's immune system is weakened due to experiencing stress, the virus is able to replicate, leading to a condition known as game illness (ゲーム病, Gēmu-byō). The virus cannot be treated with conventional medicine and progressively takes over the host's body until they disappear. The Bugster Virus cannot normally be transmitted from person to person, though later variants such as the Gamedeus virus and Nebula Bugster virus displayed the ability to do so.

Upon the onset of game illness, the infection takes over the host's body, creating a giant Bugster Union from the rapidly replicating virus. Bugster Unions can only be defeated by a Kamen Rider in Level 1. Once the Kamen Rider separates the patient from the Bugster Union, it will separate into the humanoid core Bugster based on the associated game as well as numerous Bugster Virus foot soldiers to help them fight. However, in the state the Bugster is still parasitizing the host, who will continue to suffer from game illness and eventually disappear. The patient will only be cured if the Bugster is destroyed. In some cases, such as Ju Ju Burger, the patient can be cured if the conditions for clearing the game are met, even if the Bugster is still alive. If a Bugster is not defeated in time and the host disappears, it will become a Complete Bugster (完全体バグスター, Kanzen-tai Bagusutā). This enables it to live without the need for a host, and it can be revived at any time if destroyed. They also gain the ability to adopt a human form and may retain the memories of the host. The data of the person that disappeared will be stored in the Proto Gashat from which the virus that infected them originated from. If the host dies from unrelated causes before the game illness completes its course, the Bugster will not materialize.

Even if a Bugster is destroyed while incomplete, its data can be retrieved with the Gashacon Bugvisor and used to infect another person. It will then return in an evolved form. In this case, the Bugster Union phase is skipped, and the evolved Bugster can either separate immediately or possess the host's body. The ability of Bugsters to "level up" is analogous to normal viruses evolving to resist antibodies.

History[]

Origin[]

The Bugster virus was inadvertently created in 1999 by Kiyonaga Hojo, who in anticipation of the impact that the Y2K problem could have on medical equipment had repeatedly conducted simulations of the phenomenon in order to devise a countermeasure.^{[Novel: Kamen Rider Ex-Aid: ~Mighty Novel X~]} The newly created virus escaped onto the internet and was discovered by Kuroto Dan, who showed it to his father, Masamune Dan.^{[Chasing the Mystery!]}

Kuroto Dan inserted this original version of the virus into a game known as Mighty Action C and sent it to Emu Hojo, causing Emu to become the first person to be infected with the Bugster virus. The virus would continue to mature in Emu's body until 2010. Having observed Emu, Kuroto hired Michihiko Zaizen of the Next Genome Institute to operate on Emu and harvest the virus. While Zaizen and the others operating on Emu were infected in the process and died, the virus was successfully isolated and Parado separated from Emu's body as the first Bugster. ^{[We're Me!?]} Unbeknownst to Kuroto, Masamune had had also injected himself with the original virus in order to develop antibodies as part of his own agenda.

Zero Day[]

The first Bugster outbreak took place in 2011 and is designated "Zero Day". It started when game testers were infected from 10 prototype games being developed by Genm Corp. CR was founded by the joint efforts of the Ministry of Health and Seito University Hospital to fight the Bugsters. Kuroto helped design the Gamer Driver and Proto Rider Gashats as a method of counteracting the virus. While the Bugster Virus was thought by the public to have originated from a bug in the games, Kuroto had secretly started the outbreak and was merely using the Riders and the Bugsters to gather data for better games.

While the outbreak was mostly contained, there were numerous casualties, including Heiji Uesugi's son and Saki Momose (coroner Jungo Aihara was also infected, but he died in a car accident before the virus could manifest). The Rider for CR, Taiga Hanaya, lost his medical license for failing to save Momose. As the CEO of Genm Corp., Masamune was held responsible for Zero Day and was incarcerated. Unbeknownst to anyone else, Masamune had allowed himself to be framed by Kuroto as part of his plan for Kamen Rider Chronicle.

Second Outbreak[]

In 2016, the Bugster virus re-emerged. The first known victim was a boy named Sota Suyama, who was infected by the Salty Bugster. Hoping to make the boy feel better (and not realizing the severity of the condition), his doctor Emu Hojo brought him to the release of Mighty Action X, where the Bugster took over Sota's body. In the resulting chaos, Emu was able to use the Gamer Driver and become Kamen Rider Ex-Aid, removing the Salty Bugster and defeating it, saving Sota. ^{[I'm a Kamen Rider!]}

Soon, more Bugsters began to appear as they were fought and defeated by the Kamen Riders. Graphite tried to start off a second Zero Day by using the Proto Drago Knight Hunter Z Gashat to spread the Bugster virus over a widespread area, but he was later defeated by the Kamen Riders. In an effort to find out the truth behind Zero Day, medical examiner Kiriya Kujo went to Masamune Dan, but Kiriya was later killed at the hands of Masamune's son Kuroto.

As part of his master plan to complete Kamen Rider Chronicle, Kuroto began to create leveled-up Bugsters such that he could collect their data once they were defeated. But after Kuroto was killed, Parado took over his project in his own way.

Chou Super Hero Taisen[]

As Kamen Rider Para-DX, Parado joined in the Chou Shocker Taisen, fighting in a temporary alliance with his Rider adversaries as well as Sentai Rangers against the army of Shocker from the Game World. ^{[Kamen Rider × Super Sentai: Chou Super Hero Taisen]}

The Perpetual Horde[]

As a result of Kuroto Dan's plot to revive in the Game World, an endlessly reviving horde of Bugsters emerged in the real world where they were held off by Kamen Riders Brave and Snipe while Emu was sent from CR to the Game World to stop Dan. ^{[Maze 2: Escape]} Ultimately, the Bugster army was suddenly dissipated in an instant as the destruction of the Game World brought about by Kazuma Kenzaki thwarted Dan's ambition to revive. ^{[Maze 3: Gorider Forever]}

Kamen Rider Chronicle[]

The game was eventually finished by Parado with the help of the new Genm Corp CEO Ren Amagasaki, who distributed the finished product to the public in the form of a mass-produced Rider Gashat. ^{[Start the New Game!]} Unbeknownst to them, however, the objective of Bugsters is to use it to spread the game illness so they will die upon a Game Over and disappear forever. Therefore, usage of the Gashat also infects the user with a dose of the Bugster virus, and if the player decides to quit the game without defeating a Bugster, leaving the disease untreated, the virus will eventually kill them as well.

However, after a public announcement from the Ministry of Health, the amount of people playing the game started to decrease significantly, and one of the Ride-Player survivors Tenma spread the truth across the internet about a further darkness behind Kamen Rider Chronicle. However, Ren Amagasaki and Parado have a secret plan to increase and fool the players who still have the mass-produced Gashats, which is by announcing if they won the game, the victims of the previous Bugster incidents will be revived. ^{[Players Who Bet on Survival] [Love & Peace for the Winner!]}

Months later, Masamune was finally released from jail and took over Genm Corp by force. When the Riders and the Bugsters finally have their final clash, Masamune showed himself using the power of Cronus. He later told everyone that everything had gone according to his plans. He reveals that the manipulation of himself to be jailed, the perfection of Kamen Rider Chronicle, and the succession of Kuroto were part of his plan; making Kuroto his hidden pawn and not Kuroto who pulled the strings, which surprises Kuroto himself. ^{[Judgment Received!]}

Other Events[]

"Tricks": Virtual Operations[]

Bugster Virus appeared in virtual simulation where Ex-Aid and Snipe was testing their powers. ^{[Ex-Aid Chapter] [Snipe Chapter]}

Kuroto Dan simulated his own Proto Mighty Action X Gashat and faced Graphite who sneaked into VR world. When asked why, Graphite simply said that he needed to test his competence, too. Dan then transforms and activates his Critical Strike finisher using the Kimewaza Slot Holder and cleared the simulation by beating Graphite.^{[Genm Chapter]}

"Tricks": Kamen Rider Genm[]

Collabos Bugster in his prime body reemerged with Proto Gekitotsu Robots and Proto Giri Giri Chambara installed. After quick battle with Emu, who used Kaigan Ghost, Full Throttle Drive and Toukenden Gaim Gashats, he falls on the hands of Kamen Rider Genm, who uses the power of the Legend Rider Gashats to complete his Ganbarizing Gashat. Using the blank Collabos Bugster as a conduit to harness the power of Kamen Rider Battle: Ganbarizing, a game Emu is unfamiliar with, Genm brings forth manifestations of Kamen Riders Double, OOO and Fourze. ^{[Part. I: Legend Rider Stage]}

A team of Bugster viruses appeared in the Game Area of Famista where they encounter Brave acting as baseball pitcher. Back in the real world, Poppy Pipopapo discovers the inert Collabos Bugster which she is unable to budge, projecting a blank Game Area which soon enough manifests as Ganbarizing, causing it to come back to life and go berserk before Ex-Aid arrives, allowing Poppy to get away. Taking out the Ganbarizing Gashat from the Bugster's head, Ex-Aid inserts it into his Gashacon Breaker, performing its Critical Finish to destroy the Bugster. ^{[Part. II: Legend Gamer Stage]}

Notes[]

• The Bugster virus was caused by the Y2K event, the real-world prediction that computers' 2-digit year displays becoming "00" for the year 2000 would cause all computers in the world to stop working properly, as they may believe the year to be 1900 instead. In reality, at least in part to preventative measures, very little happened.
• All Bugsters are designed by Katsuya Terada who is well known for designing the Dopants.
• The Bugsters being genetic viruses given humanoid form is reminiscent of the Amazons, especially when they begin to spread out as seen with the sequences shown.
• The virus effectively replacing the host, assuming a large form before taking on a more humanoid frame, is reminiscent of the Phantoms of Kamen Rider Wizard
  • Unlike the Phantoms, however, the virus does not necessarily use the original body when the virus claims the infected host, such as the case of Graphite's host being different from the human form it currently possesses.
  • But the way they are cultivated with their cultivators working in pairs is similar to the way the Makamou are cultivated.
    • An exception to this rule is the Level 30 Bugsters, where they not only cultivate their hosts but also possess them. And upon defeat, the Bugster Viruses would eject from the host's body similar to the Dopants of Kamen Rider W having their monstrous Gaia Memories destroyed.
• Given the series' gaming motif, the revived Bugsters altered appearance and additional abilities is likely a reference to enemies becoming more powerful and possessing new or enhanced abilities at higher difficulty levels.
• Bugsters' weapons possess their owner's name: ex. Salty Bugster's Salty Knuckle.
• Bugsters using Kamen Rider Chronicle to commit genocide on humanity and become the superior race on Earth mirrors the goal of the Orphnochs working for Smart Brain in Kamen Rider 555.
