A toxic combination of Dark Energon and the vivisected remnants of the original Galvatron, the terrifying G-Virus is an artificially engineered plague like no other. Any Cybertronian infected by the disease slowly transforms into a copy of Galvatron, with all the myriad mental problems that this brings.

Fiction

Beast Wars: Uprising

Following the Human Confederacy's destruction of Galvatron's forces during the Great Push, Galvatron was vivisected by Cybertron's best scientists. His remains were used to create the G-Virus, which was in turn locked away in Cybertron's Forever Vaults. There it remained for several centuries until the infamous gang known as the Antares Eight used a combiner to storm the Vaults and steal a sample of the virus.

Resistance member Grimlock had masterminded the heist, and planned to detonate a canister of the virus in Tesarus Arena. The transformation would cripple thousands of Builders, leaving them immobile and insane. However, several hundred Micromasters as well as Resistance POWs being forced to fight in the Game would become mobile Galvatrons. While attempting to execute his plot, Grimlock was confronted by Hot Rod. The two fought; Snapper, the only other survivor of Grimlock's squad, planned to go through with Grimlock's plan until Hot Rod informed him what the virus was, and the disastrous effects it would have. Snapper chose to destroy the virus, earning him Grimlock's enmity.

Meanwhile, Cop-Tur, sole survivor of the massacre of the Forever Vaults, succumbed to his brief exposure to the virus, mutating into a Galvatron and escaping Micropolis's infirmary.

Uh-oh... Micro-Aggressions

Elsewhere, Eject used the virus as part of his "Galva-Contingency", mixing the virus with a clone of Lio Convoy to create Galva Convoy. A few cycles after his creation, the newborn Maximal was tempted by a mysterious source to use both aspects of his design to corrupt the energon matrix within him. Not All Megatrons Eventually, Galva Convoy succeeded in doing so, creating three "Vehicons". Due to the nature of their origin, the Vehicons all contained a trace of the G-Virus within themselves. During the following Vehicon Apocalypse, this shared fact of physiology allowed Galvatron to avoid their touch. Derailment

Some ten thousand years later, shoddy historians misremembered the G-Virus as the Genesis-Virus. Lio Convoy: Unity Through Tyranny

Notes

• The G-Virus's name is coincidentally similar to that of the T-Virus from the video game series Resident Evil (or even the less-known but identically named G-Virus from Resident Evil 2). What did you expect? The author is from an evil universe, after all.
