"Welcome to Megaframe!" -Megabyte

Megabyte is a power-hungry, egotistical, and ambitious virus from Mainframe. He is impeccably dignified and sophisticated, however, and always wants to make a good impression, even when he is trying to infect the Super Computer. However, he is also very sadistic, punishing his servants and taking sick pleasure in the agony of his enemies. Megabyte can infect most anyone as long as he can get to their PID. However, he is incapable of infecting a city's leader, such as Phong.

Megabyte also has the ability to attach and detach his legs whenever he is sitting on his hover throne and has deadly retractable claws from both his knuckles and fingertips. He also has a control panel on his left arm that can store codes to control programs and functions of what ever system he is in as well as containing a self destruct program. He can also regenerate his body from any damage sustained in cyberspace. He has a pet null called Nibbles whom he referred to as "father". Nibbles was later revealed to be a nullified sprite of Welman Matrix who was Dot and Enzo's father. Welman was responsible for bringing Gigabyte into the Twin City, which resulted in him splitting into Megabyte and Hexadecimal, possibly explaining why Megabyte might view him as a father.

Megabyte and Hexadecimal

Megabyte was known all over Mainframe for his reputable fights with his sister, Hexadecimal. The pair were created when the virus Gigabyte was caught in an explosion, and each got specific attributes: Hexadecimal got insanity and strong, chaotic power; Megabyte got brawn and a calculating thought-process.

Megabyte on his Throne

Megabyte with his pet Nibbles

After arriving in Mainframe, Megabyte infected the city's industrial sector, Giedi Prime. All the binomes living there have been infected and are completely loyal to him. All the sectors buildings have been turned into construction facilities to build anything he may need in order to take over the rest of the city or other systems. He ruled the sector from his tower, the Silicon Tor.

Megabyte's Viral Symbol

The Commander of Megabyte's military was Lieutenant Chauncy and the head of his science and research was Herr Doktor. His main henchmen were Hack and Slash.

Infected by the Medusa

Hexadecimal and Megabyte entered into a brief partnership and he paid his sister several visits at her Lair, however it was merely a ruse to trick Hex so he could get to her stock of powerful viral weapons. He stole the Medusa Bug from Hexadecimal. Unbeknownst to Megabyte, Hexadecimal let him escape, despite destroying an attack group of ABCs. Megabyte went back to the Silicon Tor and activated the small device, and it was revealed to be not a weapon, but a viral bug. The Medusa quickly infected his arm and Hexadecimal taunted him through a VidWindow as he turned to stone. The Bug infected the Tor and moved on to the rest of Mainframe. The cities leaders first suspected Megabyte for the dangerous Bug, but ruled him out when they realized the Tor was already infected. (The Medusa Bug)

Megabyte in the Core Energy

Megabyte staged several attacks on the Principal Office in attempts to steal Mainframe's Core Energy. He finally succeeded in getting past the CPU Forces and began funneling the Core Energy into a containment module. Bob tried to stop him but a Game Cube loaded into the system. The Game distorted due to the loss of the Core Energy and landed on the Principal Office, trapping the energy, Bob, and Megabyte. Megabyte was in contact with the energy at the time and the Road Warrior Game turned him into a truck hauling the energy. Bob managed to get the energy back to the Principal Office just as the Game ended. (Bad Bob)

Megabyte invading the Core

Hexadecimal helped Megabyte break into the Principal Office by creating a fake upgrade. He defeated Bob and copied Phong's read-only memory. Using the command codes he entered the Core Control Chamber and began to erase Mainframe. Bob and Dot managed to finally defeat Megabyte by tricking him into entering a deletion chamber, pretending it was a portal generator. Megabyte started a self-destruct program to take Mainframe with him, and Bob ended the deletion and ejected Megabyte from the Principal Office. (Infected)

Using a Leech Command, Megabyte suctioned energy from Game Cubes and broke into the city's Archives. During this process Megabyte and Bob were trapped in a Game and Bob saved Megabyte just before the User deleted the virus. They stole the control circuitry for the Gateway Command and rebuilt the device in the Tor. To test it Megabyte sent Enzo Matrix through it and he entered the Super Computer. Bob and Dot tried to stop him and the Gateway and the control circuitry were destroyed. Megabyte allowed them to leave to repay his debt. (When Games Collide)

Megabyte Painted

Hexadecimal entered an artistic stage and broke into the cities Archives. She infected the system's paint program and began painting the city and everyone in it. Hex was not satisfied with the ungrateful response of the Mainframers and decided to see what Megabyte thought of her art. She painted the Silicon Tor yellow with her name on the side, and put massive daisy flowers into it, like a giant flower pot. Megabyte was furious at Hex for destroying the Tor, so she painted him up like a clown and pasted him into the city's sky as a still painting. (Painted Windows)

Web War

Merging with Hexadecimal

Infected by a Web Creature

For a brief time, Megabyte was infected by a Web Creature and became a primal black version of himself, obsessed only with merging with Hexadecimal to recreate Gigabyte. Gigabyte was eventually reformed, but Bob used a portal to split Gigabyte back into Megabyte and Hexadecimal. (Nullzilla) (Gigabyte)

Working with Mouse

After a Web Portal opened over Mainframe, Megabyte agreed to an alliance with Bob and Hexadecimal in order to close it down. Megabyte constructed the Hardware, Phong provided the software, and Hexadecimal powered it. Megabyte and Herr Doktor worked with Mouse in operating the craft. The CPU forces were quickly losing the fight and Megabyte had his ABCs launch and support the CPUs. Using the cooperation and Web War to his advantage, Megabyte was able to get rid of Bob. Just before closing the portal, Megabyte removed and crushed Glitch, forced Bob into a missile and launched him into the portal.

Declaring victory

Once the portal was closed Megabyte ordered Lieutenant Chauncy to destroy the remaining Web Creatures and then blow the exhausted CPU fleet out of the sky. Hexadecimal laughed as she began to recharge the Hardware and turned it towards the Principal Office. Then Megabyte and Hexadecimal contacted the Principal Office and ordered Phong to lower all defenses on the building. Phong told the viruses they would fight them until the last, and Guardian Enzo vowed to protect the city as Bob had. (Web World Wars)

Unbeknownst to him and everyone else at the time, when he damaged Glitch a small amount of Guardian code was transferred to him.

The Viral Wars

The Viral Wars started as the Web War came to an end. Most of the city's forces were destroyed in the following battle. Megabyte watched as Hexadecimal used the Hardware to fire on the Principal Office, damaging its shields. The cities remaining nine CPU ships prepared to dock at the Principal Office and they lowered their shields. The buildings Anti-Aircraft Guns managed to destroy the ABC tanks following them, but one crashed on the Principal Office shield generator.

Megabyte trying to stop Hex

Hexadecimal prepared to fire again, but Megabyte told her not to because it would destroy the Core and the entire system. Hex thought the resulting explosion and chaos would be glorious. The Principal Office managed to deflect the second shot, but Hex prepared to fire again. Megabyte tried to stop her from destroying 'his city' and lunged at her. Hexadecimal easily flung him aside and returned to the Hardware. Megabyte fell off the platform and was caught by Hack and Slash and carried back to the Tor.

Hexadecimal Captive

Hexadecimal was severely damaged when a Game Cube landed on the Hardware before she could fire again. The Hardware exploded and Hex was all but destroyed. Megabyte had her retrieved and imprisoned in the Tor. Herr Doktor was given orders to repair her.

Megabyte and his forces

To wear down his enemies, Megabyte organized propaganda against Enzo and attacked his inexperience. (To Mend and Defend)

Once Hexadecimal was repaired, Megabyte had a pain collar installed on her. When she was awakened he activated it so she would know she was not allowed to leave. (Between a Raccoon and a Hard Place)

Megabyte and Enzo

Megabyte paid Enzo and AndrAIa a visit after they finished a Game. He told the 'boy' to deliver a message to Phong and his sister. That they may be safe behind the Principal Office shields, but the people of Mainframe would suffer.

The Firewall activating

Phong and Mouse eventually developed a firewall capable of enclosing Giedi Prime to imprison Megabyte inside. (Firewall)

Megabyte made one attempt to break through the firewall. He had Hexadecimal's containment chamber moved to the firewall with his entire army ready to move. Megabyte ordered Hex to use her powers to breach the firewall or suffer. Hex opened a small rift in the wall and the ABC were able to move through, two by two. The Principal Office was able to put out enough firepower to make the ABCs turn back and Megabyte closed the rift. He lost Lieutenant Chauncy in the assault. (Game Over)

Megabyte invading the Principal Office

Hexadecimal eventually broke free, destroying the Silicon Tor and overloading the firewall immediately. She used a horde of Nulls to devastate most of Megabyte's ABCs and she personally destroyed Hack and Slash. Hexadecimal eventually grew bored of the fight and went back to Lost Angles. Megabyte took every binome and ABC he had left and attacked the Principal Office. Megabyte conquered it and everyone except Phong escaped. Phong was beheaded and Megabyte kept him in a jar so that he could retrieve information to control Mainframe's Core. He renamed the city Megaframe and diverted all the systems resources to defending the Principal Office and fighting Dot's rebellion. (Megaframe)

Megabyte and Phong

Eventually, Bob returned along with Matrix, AndrAIa, and the crew of the Saucy Mare. With the return of Bob, Megabyte knew that Megaframe was back on the Net. Megabyte ordered Herr Doktor to extract portal command codes from Phong so that he could leave the dying system.

Megabyte and Matrix

The Saucy Mare joined with Dot's rebellion and attack the Principal Office. The Saucy Mare was evacuated and loaded with explosives. It was used to destroy the remains of Megabyte's ABCs. With no air cover, the rebellion was able to stage an all-out attack on the Principal Office.

Megabyte being pulled into the Web

Matrix made it into the control centers and found Phong. Megabyte cornered Matrix, recognizing the 'boy', saying he will enjoy killing him. AndrAIa threw her trident to Matrix and he blocked Megabyte's claws. Megabyte and Matrix engage in a fight taking them to the higher levels of the Principal Office. In the last moments of the fight, Megabyte gained the final codes from Phong and formed a portal to the Super Computer. Matrix managed to defeat Megabyte but decided to show mercy, as he was better than the virus. Megabyte got away, injured, and prepared to enter the portal. However Mouse hacked into the portal and redirected its destination to the Web. Megabyte was pulled in by Web Creatures and the portal vanished. (Showdown)

The Return

Megabyte's New Form

Megabyte secretly returned to Mainframe shortly after the demise of the Super Virus Daemon, having transformed into a Trojan Horse virus. He is more dangerous than ever in this state because he can adopt the appearance of any person he has come in contact with, to the point of fooling system scans.

Megabyte was brought to Mainframe by Ray Tracer just after the defeat of Daemon. He had taken the appearance of Bob by using the Guardian code he had accidentally taken from Glitch during the Web War. Megabyte fooled everyone and proceeded to slowly move in on Dot Matrix. The real Bob became frustrated, realizing that Dot was falling for the original looking Bob. He attempted to separate from Glitch but failed and was trapped in a black cocoon.

While the real Bob was rushed to the Super Computer for treatment, Megabyte proposed to Dot and they started laying plans to get married. Bob was eventually freed by the return of the Guardian Key Tools. He quickly rushed back to Mainframe and crashed the wedding. Dot told him to leave and sided with the fake Bob. Glitch flew to the fake Bob and everyone thought the real Bob was the copy. As Bob was leaving Glitch took the original guardian code from Megabyte and returned to Bob and loaded the code into him. Bob returned to his original form and Megabyte, unable to hold that shape, reverted to his real form.

Megabyte and Bob began to fight and destroyed the wedding chapel in the process with the Virus amazed by Bob's new strength. When the fighting stopped for a nano-second Bob asked Megabyte why he had done this. Megabyte said, "It amused me." He temporarily blinded Bob and went back to the wedding chapel, stopping just long enough to kiss Dot. Then Megabyte went into the chapel and grabbed Specky, changing into his form, allowing him to escape unnoticed. (Null Bot of the Bride)

Megabyte running the War Room

While Mainframe's leaders were having a meeting to figure out what to do, Megabyte impersonated Mike the TV and told the entire city to panic. He then went to Al's Wait & Eat and found a few of his former military leaders there. He was pleased to find Herr Doktor and Lieutenant Chauncy there. After revealing himself to them, Megabyte ordered them to surrender their PIDs and together they would usher in a new viral dawn. As an example of what would happen if they resisted, Megabyte forcibly infected Al's Waiter with his new tendrils.

Megabyte takes control of the Principal Office

Megabyte was able to distract the Mainframers with an aliased copy of himself and forcibly took control of the War Room. He locked down the Principal Office and warned everyone that he was there for revenge, and to prepare themselves for "the hunt." (Crouching Binome, Hidden Virus)

Comic (Non-Canon)

The events of the Hunt are not fully known, but it left Mainframe devastated and overrun by murderous zombinomes. The entire System had to be evacuated to the Super Computer, though Welman Matrix was left behind. Megabyte placed a spyware device in the Super Computer and so was able to prepare a defense against the Code Master antiviral weapon Gnosis, but this failed and Megabyte was seemingly killed. Megabyte acted as the spokesman for Gnosis, though this was later revealed to be a backup created by Gnosis. However, after the defeat of Gnosis, it was stated by Bob that "even Megabyte" was restored. (Paradigms Lost)

Reboot: The Guardian Code (Alternate Continuity)

"Forgive me, but I appear to have been dormant a great many cycles. Is this about Bob?"

"It seems I have been... digitally enhanced."

In the new series, twenty years after Mainframe was shut down, a User named The Sourcerer hacks into the system and reanimates Megabyte. Immediately after, he upgrades the virus' appearance and abilities. To keep the virus under his control, The Sourcerer installs a delete code into Megabyte's new body, which he uses on occasion to incapacitate and even threatens to destroy Megabyte with in the event the virus goes rogue or fails to do the Sourcerer's bidding. (Resurrection)

After being pulled from Mainframe by The Sourcerer, Megabyte breaches the mobile game "Fortress Command" and hijacks the game's fortress, which becomes his new lair, and infects several of its game sprites, turning them into viral sentinels with an Alpha Sentinel in command... which is often destroyed- either at Megabyte's hands or by the Guardians' efforts- and replaced. (Fortress Command)

Several of Megabyte's missions included the previously-aborted sabotage of a power grid in the UK (Resurrection), infecting the internet with a Cat Video virus as a distraction for the Sourcerer to steal a prototype super-computer (Catastrophic), destruction of an online banking system (Emotional Rescue) and the hijacking of a military weather satellite to cloud-seed a tropical storm into a hurricane (Datastorm). In each case, he has run afoul of the Guardians, who thwart his plans with mixed success.

Megabyte plotted to free himself of the delete code implanted into him, as The Sourcerer's promises to remove it are always put off until a later time. To that end, he even went to temporarily ally with Hexadecimal, who is surprised of his new appearance. Not long after, he abandons her to be arrested and thrown into the Virusylum. After being ordered to deal with the Guardians and give him the secret to their travels in cyberspace, he forces the Sourcerer to relinquish his control over him, as promised, to which he reluctantly complies. When the Guardians escaped, Megabyte began a ruthless quest to infect Social Media City, where he interacts with, or rather terrorizes the "Users" of the human world. Megabyte was temporarily thrown into Virusylum, but was forced to partner with Hexadecimal once again, though he recalled that experience as "seeing the future". Though the Guardians attempted to get them back into the prison, both viruses managed to escape nonetheless.


  • Megabyte's name is a reference to a unit of computer memory.
  • Megabyte, in general, has made references to the Borg from Star Trek. The most overt example is from Between a Raccoon and a Hard Place, where the Jean Luc Picard binome gives a speech reminiscent of Captain Picard's speech in Star Trek: First Contact. Megabyte's response was the Borg motto, 'Resistance is Futile.' His appearance in the fourth season went even further, having him capable of infecting others using tentacles that protrude from his hands, also a Borg staple. It may be worth noting that Megabyte's voice actor, Tony Jay, was a guest star in an episode of Star Trek: The Next Generation and that he also played villain "Nigel St John" in some episodes of Lois and Clark: The New Adventures of Superman.
  • In seasons one through three, Megabyte removed his legs to physically merge with a hover throne, although no reason was ever given as to why.
