Gigabyte is a class 5 energy absorbing Super Virus created from the virus Killabyte. Killabyte was captured in the Super Computer and was scheduled for deletion, but just before the procedure he received an upgrade from the User that programmed him. He quickly grew several sizes, and gained the ability to to fly, form portals, with trans-finite power reserves, and drain energy from any sprite, binome or powered equipment. At this point the new virus began calling himself Gigabyte, Destroyer of Systems. (What's Love Got To Do With It? )

Just after Gigabyte's upgrade, he was caught in a Gateway Command from Mainframe's Twin City and was pulled there. When he arrived he unwittingly damaged the gateway causing it to overload, destroying the entire city. The explosion nullified everyone in the Twin City and also split Gigabyte in two, creating the new viruses Megabyte and Hexadecimal.

Gigabyte was briefly reformed when a Web Creature infected Megabyte forcing him to merge with Hex again, in a bid to reach the Net, forming the super virus Gigabyte. Once Bob found what Gigabyte was he initiated a Net wide alert that there was such a powerful new virus, calling for any assistance.

Mainframe had never previously encountered any threat of the sort. His personality was a perfect balance between Hexadecimal and Megabyte, as he possesses both incredible power and a cold machine-like intelligence. This makes the Super Virus very dangerous since he has none of extreme-traits present in the two viruses that made him up, neither joyfully insane like Hex, or a greed of Megabyte.

Because of his energy absorbing abilities, Gigabyte cannot be harmed by energy-based weaponry from Glitch, however he is not invincible to all forms of attack; he can be directly impeded by physical assaults or weapons such as Mouse's katana, but even these do not leave any lasting injury, should Gigabyte sustain heavy damage he can easily repair himself in seconds.


Bob, realizing this virus was far from 'benign', fought Gigabyte while trying to keep him from getting any power. He was effortlessly tossed aside by the virus. At first there seemed no logic to this pattern, until Phong correctly surmised that his transformation left him very weak because Hexadecimal had been all but drained of power by nulls. Gigabyte would seek out the largest sources of energy, so Phong quickly powered down the city, leaving the Guardian and Glitch as the biggest energy source, apart from the System Operating Core. Bob lured Gigabyte to Floating Point Park while the rest prepared to put their plan to degrade the virus into effect.

Bob was still no match for the virus' brute strength but was fortunately backed up by Hack and Slash. The two robots combined strength was enough to actually put up a fight with the virus, however their luck ran out when Hack accidentally got too close and was drained of energy. Slash in a temper sent Gigabyte reeling with a punch, but idiotically, straight back to Mainframe. With Hack's energy Gigabyte could now fly and tapped into the Principal Office's shields, forcing Phong to bring them down before the virus became too powerful to stop. The Mainframers kept stalling for time, so Gigabyte wouldn't reach the Core.

Together with Mouse and Dot, Bob eventually caught and defeated Gigabyte in a tear and using Glitch, managed to split him back into Megabyte, Hexadecimal, and the Web-Creature, destroying Gigabyte for the second time, and reforming his children.


  • His name is a reference to a unit of computer memory.
  • His catchphrase is a reference to the line "I am become death, the destroyer of worlds" from the Hindu scripture Bhagavad Gita.
    • The line was famously quoted by an American theoretical physicist J. Robert Oppenheimer, upon witnessing Trinity, the world's first nuclear test.
  • Gigabyte was termed a Super Virus in the book, The Art of ReBoot, by Dave Roberts, Gavin Blair, Brendan McCarthy, and Scott Lee.
  • Bob later tried to use the same method of splitting up Gigabyte to separate himself from Glitch in Life's a Glitch. However for him it went horribly wrong.
  • It appears that both he and his two halves Megabyte and Hexadecimal have no knowledge of the others' existence.
  • During Gigabyte's second chronological period of existence, he had several tendrils reminscent of Web Creatures jutting out from his back, due to a Web Creature having possessed Megabyte earlier and becoming part of the combination.
  • After the Web War, Hexadecimal had several physical and mental changes, to the point of being a sprite, causing that Gigabyte didn't return after the Hex's demise in the Net War. Megabyte also suffered changes because he was sent to the Web, giving him the Trojan virus powers and a different look.
