"I come from the net. Through systems, peoples, and cities, to this place: Mainframe. My format, Guardian: to Mend and Defend. To protect my new found friends, their hopes and dreams, To defend them from their enemies." -Bob

Bob is a Guardian from the Super Computer. He is formally designated Guardian 452 and is the protector of Mainframe from its various internal and external threats. His Key Tool is named Glitch that he wears on his left wrist. The Guardian motto is "To Mend and Defend," and Bob takes pride in doing just that. He is always trying his best to keep Mainframe's enemies at bay.

Bob enjoys taking things as they come, is impulsive, and rarely plans anything. When he's not defending the system, Bob can be found either in his garage, fixing his perpetually broken 262 convertible, or in Dot's Diner trying to pry Dot Matrix away from her work.

Bob loves Dot Matrix. Early on they didn't talk about it much, being too shy to actually admit to it. During the Treasure of Atlantis Game, Bob and Dot rebooted as telepathic merpeople, and he was caught admiring her.

Bob as a cadet

Bob and Dixon Green

While training as a cadet in the Super Computer, Bob helped arrest Mouse. She was trying to hack into the system. The two formed a friendship that has lasted through the years. Bob doesn't exactly trust Mouse, but he likes her.

Bob and Mouse

Bob serves under Turbo and was trained by Dixon Green. His roommate at the Guardian Academy was Cardon. Even as a Cadet, Bob was fairly unique among Guardians as he was in favor of non-violent alternatives to dealing with Viruses rather than executing nefarious being. Bob believed it wasn't their fault a User made them this way.

Bob meets Dot

While talking to his partner, an upgrading Killabyte broke free and dealt Dixon a fatal wound. Bob was heartbroken at the loss of Dixon. Her Key Tool Glitch joined with Bob. Bob came to Mainframe chasing the virus Gigabyte that killed Dixon. When he arrived in what remained of Mainframe's Twin City he was utterly shocked to see all the surrounding chaos and devastation. This is when Bob meets Dot Matrix. She was in shock over the loss of the city and her father and initially blamed him for all the destruction.

Bob decided to stay in Mainframe and protect the city from the new viruses, Megabyte and Hexadecimal. Megabyte quickly took control of Giedi Prime sector, while Hexadecimal took the island of Lost Angles as her home.
Bob himself took residence in Eight Ball Apartments in Kits Sector, on the top floor. His apartment has everything from a picture of the Super Computer captioned with the phrase "Home, Sweet, Home," to an assembly-line style shower, to a very annoying talking television, Mike the TV.
After his arrival, Bob grew very close to Dot Matrix. Bob also gradually trained Enzo Matrix on how to fight in Game Cubes, though Dot discouraged Enzo from following him into Games.

Bob and Megabyte

Bob was somewhat naive about living in a small system. Megabyte tried to trick Bob into stabilizing a tear into a portal to the Super Computer. In an attempt to persuade Bob, Megabyte prevented him from aiding a sub-sector in winning a Game, causing it to be nullified. Bob tried to take care of the situation alone, but eventually learned he could not, because Mainframers always stick together and help each other out. (The Tearing)

The Mainframers discovered that Bob was immune to viral bugs when Hexadecimal's Medusa Bug began infecting the city, and his Guardian code was strong enough to protect him. The rest of the city was turned to stone until he figured out how to restore them. (The Medusa Bug)

Bob assisted Phong and Dot in installing a system upgrade. Megabyte had teamed with Hexadecimal to create a fake upgrade with Megabyte inside. He gained access to the Core Control Chamber and started to erase the city. Bob tried to fight Megabyte but Glitch lost power. They were forced to abandon the chamber and find other weapons. From the wise advice of Phong, Bob managed to use Megabyte's greed against him by tricking him into stepping into a virus decompiling chamber and ejecting him from the Principal Office. (Infected)

The Web War

Hexadecimal was infected by a baby Web Creature that came to Mainframe through her Looking Glass. The cities nulls covered her to protect the city, forming a monster named Nullzilla. To stop the monster, Phong had a Giant Robot that Bob, Dot, Enzo, Frisket, and Mike the TV piloted to fight the monster. Bob felt ridiculous in their battle costumes.

Bob fighting Gigabyte

The Web Creature bonded with Megabyte next and forced him to merge with Hexadecimal, reforming the super virus Gigabyte. Bob found himself outmatched by this powerful virus. By overpowering him they managed to split Gigabyte into the three individuals.

The Web Portal

Dot Matrix went missing on Level 31 and Bob went searching for her. Mouse was also on the trail. They eventually found the Web Creature, grown to a large monster. Turbo and the Guardians activated an explosive to destroy the Web Creature, but it would also destroy the entire city. Bob quickly got the bomb into the sky, and it exploded over the city. The Web Creature flew to the massive tear the bomb had made and turned it into a portal to the Web.

Making Enzo a cadet

Bob helped Phong fortify Mainframe and fight off the Web. They formed an alliance with Megabyte and Hexadecimal. Megabyte built the Hardware to close the Web Portal, Phong downloaded the software to run it, and Hexadecimal powered the device. Mouse hacked the Web and erased Mainframe's location. In case something would happen to Bob, he gave an upgrade to Enzo. Bob downloaded version 1 Guardian code to Enzo's icon, making him a cadet, and charged him with the defense of Mainframe.

Bob thrown into the missile

Megabyte betrayed Bob as the end of the war neared. When the hardware was ready to close the portal, Megabyte attacked Bob and crushed Glitch, which unknown to either at the time transferred some of his guardian code into the virus. Then he threw Bob into a missile and shot it into the Web. Then he activated the hardware and closed the portal, stranding Bob in the Web.


Bob degraded by the Web

Bob rescued

While in the Web, Bob's uniform degraded due to harsh environment. He encountered a group of degraded sprites called the Web Riders, who took him in and taught him how to survive in the Web. Bob quickly learned the squeak language of the Web Riders, and rose to prominence among their ranks. Bob's appearance continued to change the longer he spent in the web, causing his hair to grow long and lose some of its shiny luster, along with silver scales and Web scars developing on his head and neck. Bob created a mask out of Web Creature scales for protection against the Web's environment. His voice had also been slightly affected, growing higher in pitch. It was later said that he took the form of Interface.

The next year, Matrix and his friend AndrAIa were lost on the Net during the Viral Wars. They met up with The Crimson Binome and the pirates of the Saucy Mare. They teamed up with the surfer Ray Tracer and entered the Web to search for Bob. He was eventually found much to their delight and they celebrated.


They took the Saucy Mare to Mainframe's Web Address to return home. When they arrived the location was protected by several traps laid by Mouse. The ship was nearly destroyed. The Web Riders and Ray Tracer went outside the ship to protect it. They became separated from the ship by a massive shield and began pushing the ship toward the tear marking Mainframe's location. Bob and Glitch came up with a very unorthodox idea. In order to save themselves and return to Mainframe, Bob downloaded Glitch into himself, upgrading him. His uniform transformed into a lustrous silver and gold armor, which imbued him with Glitch's lost powers. He removed the ship's Web Shields and formed a portal to their home.

When they returned to Mainframe they found the city all but destroyed by the Viral Wars. Bob and Matrix inspected the remains of the Silicon Tor and realized Hexadecimal destroyed the tower and a battle began between the two viruses. Afterward, Megabyte attacked the Principal Office and took control of the city.

They soon ran into Hack and Slash. The pair took Bob and Matrix to Dot. She and Mouse were leading the Mainframe rebellion. Dot was relieved to have Bob back but was overwhelmed to have her little brother returned as well. Megabyte found out about Bob's return and realized the city was back on the Net. He used the captive Phong to explode the Sub-Sphere, preparing to turn the new tear into a portal.

Curing Hex's mask

Before they could attack, Bob was kidnapped by Hexadecimal. She was more insane than ever, due to the damage that had inflicted her mask. Bob managed to treat the damage to her mask and in thanks, she returned him to Dot.

Phong, Hexadecimal, and Bob

Megabyte had been defeated, but the system had been so damaged by the wars that it began shutting down. Bob suggested that they allow it to crash and hope the User would begin a restart. Although many didn't like the idea, they allowed a Game Cube to damage the city further and cause it to crash.

Bob and Dot

As the system began to crash, Bob begged Phong to give an icon to Hexadecimal. He knew that she would not be restored with the rest of the system if she was not registered with the Principal Office. Phong finally agreed, though thinking this decision was "absolute and utter madness".

The User restored the system and the city came back online and everyone in the city was saved. Dot told Bob to never leave her again, and he said he wouldn't. They finally had a passionate kiss as the city came to life around them. Suddenly they heard someone yell for Bob, he turned and was flattened by the kid version of Enzo, a system copy of the original. They named him Little Enzo.

The Net War

Bob helped Mainframe fight off the virus Daemon and the Guardians. When she found out that he was joined with Glitch she named him her messenger because he was the only guardian left that could create portals since all the key tools left the Guardians because of Daemon's infection.

Bob and Hex

The Guardian Armada invaded Mainframe at the beginning of the War. Bob couldn't stand to see his fellow Guardians deleted so he tried to contain their ships, one by one, in file locks. Bob convinced Hexadecimal to help them, and she expelled the entire Armada from Mainframe, and Mouse resealed the system. The effort drained Hex enough to make her vulnerable, a virus scan from the User turned her into a sprite.

Bob transparent

When Matrix captured Turbo, Bob used what little guardian he had to partially cure his old friend. He and Dot then learned that Daemon seeks to bring unity to the Net and needs Bob to create portals to the closed or offline systems to infect

Bob fell ill during the war. Phong performed a complete compile on Bob and found that the merge with Glitch was not entirely successful, as the Key Tool had been badly damaged at the time of their merge. Due to this, Bob was effectively breaking down. Phong also tells Bob that the continued use of his Glitch powers will result in total fragmentation, leading Bob to make Phong swear to not tell Dot. Bob also discovered he was no longer capable of rebooting, but it is unclear if this is a result of his partial Web degradation, his merging with Glitch, or both.

During one of his talks with Turbo, he disagreed to destroy Daemon, believing he could reprogram her but Turbo insisted that the entire Net was at stake.

Daemon arrives

Daemon eventually breached Mainframe's defenses. She was overjoyed to meet her messenger. Daemon noticed Hexadecimal next to Bob and called her an abomination, a disgrace to viruses. Bob defended Hex and Daemon disregarded his anger, and infected the entire city. Hexadecimal asked for forgiveness and Daemon threw her into a wall.

Being infected

Daemon took Bob to the portal generator and forced him to form portals to any offline system so she could infect the entire Net. Each effort to form a portal degraded Bob further.

Little Enzo and Matrix found a cure, the pure Guardian code in Matrix's icon. They used it to cure AndrAIa, Hexadecimal, and Phong. Hexadecimal went to the Core to get more firepower to fight Daemon.

Hexadecimal dancing with Bob

When Daemon's infection of the entire Net was finished, Bob collapsed at the steps of the Principal Office. Hexadecimal appeared, fully viral again, and attack Daemon. The two super viruses battled, destroying sections of the city, but never hurt each other.

Dot proposing to Bob

Daemon reached the end of her life, announced the word is 'Cron', and decompiled. Everyone infected began counting down to their own deletion. Bob explained to Dot that a Cron Virus is programmed to create a total crash. Hexadecimal grabbed Bob and began dancing insanely. Bob explained to her they were all going to die. Hex demanded they stop it. Welman Matrix told her they had a cure and a virus could distribute it, but Phong realized that it would cause the virus total fragmentation. Hexadecimal decided to do it to save Bob, her final words were, "Bob, I have always loved you, Dot take care of him, and be happy." She then left and saved the entire Net.

Bob collapsed and Dot began to cry, asking him not to leave her again. Dot then asked Bob to marry her. Bob accepted and she leaned it to kiss him. A portal appeared in front of them and Ray Tracer stepped out, with a second Bob identical to his old self.

The Return

Glitch Bob and the fake Bob

With the second Bob in Mainframe, the real one couldn't stand it. As the new Bob resembled the Guardian as the people of Mainframe originally knew him, some started to believe that the first Bob was the copy and the new one was the real one. To make things worse, Dot refused to let the first Bob into Games due to his illness.

Bob encased

Desperate, Bob finally decided to try and separate from Glitch. He tried several teleportation machines to separate them but nothing worked. Finally, he came up with the idea to use a portal. When Gigabyte was separated back into Megabyte and Hexadecimal they used a portal and split it. He decided to do the same thing. The action backfired: the portal imploded when it tried to split in two. Bob was left immobile, encased in a hard black covering that nothing could penetrate. He was rushed to the Super Computer for treatment

The Dream

Soon after Bob was taken to the Super Computer, the second Bob proposed to Dot, and she accepted. They prepared for their wedding while Bob remained in treatment. Nothing they tried could penetrate it. Bob had a strange dream where he says a massive Glitch while wondering if he was the copy. All the Key Tools returned and went into Bob's body.

Bob changing

As the wedding began back in Mainframe, Bob's body began to glow.. The Key Tools returned through small black portals and used energy beams to save Bob, restoring him back to his pre-merged form while upgrading Glitch, now separate once more, back into his full functionality. Despite this, Bob's code didn't match what the Guardians had on file.

Bob and Megabyte fighting

Bob quickly went to the Wedding and crashed it. Despite his return, Dot was not convinced of his identity as the true Bob, and he was told to leave. Conceding defeat, Bob tearfully sent Glitch to the second Bob. However, the second Bob immediately doubled over in pain, as Glitch proceeded to pull some code from him and return to the first Bob, giving the code to him. The first Bob returned to his original form, and the second Bob transformed into Megabyte, having been transformed into a shape-shifting Trojan Horse virus. They battled, destroying the wedding, and then Megabyte shape-shifted into a binome and snuck away.

In the Brig

Dot came up with a plan to trap Megabyte with a fake Gateway Command. Megabyte took the bait and Bob, Matrix, AndrAIa, Frisket, and a team of CPU's were able to capture Megabyte. Back at the Principal Office, Bob performed a scan of Megabyte and found there was nothing there: it was an alias. Matrix deleted the alias and Bob quickly informed Dot in the War Room that Megabyte must be in the War Room with her. Megabyte attacked everyone, some got out, others were infected. He locked down the building and informed everyone he wasn't there to conquer Mainframe or the Super Computer, but for revenge. He said to prepare themselves for the hunt.

Alternate Timeline

Null Bob with Phong

During an effort to free one of the sectors of Giedi Prime controlled by Megabyte, Dot became disillusioned and lost confidence. To help, Phong used a device on Dot called a Reality Distortion Engine. It made it so she could see what would happen to Mainframe if she did nothing to stop Megabyte. In this horrible future Megabyte ruled what was now Megaframe, Enzo was a gang punk, and Phong was driven insane and was living in a box in an alley. Bob had been nullified in a Game and was living with Phong as a pet. He was kept in a small cage and, as a Null, could not recognize Dot. (Identity Crisis, Part 2)

Comic (Non-Canon)

Bob helped the binomes and Sprites evacuate Mainframe and attended Little Enzo's graduation ceremony in the Super Computer. However, Turbo saw Bob's views towards Viruses as a weakness, calling him a virus sympathizer, saying that if he had just deleted Megabyte when he had the chance instead of letting him go all the time none of this would have happened. Bob took this advice to heart, along with Little Enzo's speech, and he single-handedly went to Mainframe to delete Megabyte once and for all. Turbo called him back as the Code Masters had come up with a device to delete all of the viruses. Later after the Code Masters destroyed all of the viruses in the Net, Dot and Bob went to a cheap chapel for a quickie marriage from Mike the TV.

ReBoot: The Guardian Code (Alternate Continuity)

Bob as he appears in the Guardian Code

In the new series, Bob was restored along with Dot and Enzo when an outside user and guardian named Parker (codenamed Googz) booted up an old Mainframe computer found in room 0.

Bob then teams up with three new upgraded guardians Googz, Vector and Enigma who he bumps into in Baudway, outside Dot's Diner. They explain that they are guardians from outside the net and have the same objective as Bob to protect Mainframe.

He is also shocked to hear that Megabyte is back and causing more trouble in Mainframe.

They fight Megabyte who has teamed up with a restored Hexadecimal and his evil sentinels. But suddenly a game dropped by a user called "Escape from Alcatraz" comes down and Bob, Googz, and Vector enter. They succeed in beating the user by Googz and Vector remembering a tactic outside the net on how to win and Mainframe is restored. Bob then congratulates his new friends who promise him that they will carry out the mission of all guardians: To Mend and Defend. (Mainframe Mayhem)


  • According to Gavin Blair, Bob's original name was "Chip". However, they liked the name Bob better. After they had already named him Bob they thought of the idea that the name could mean Binary Object.
  • Bob has no last name. The origin of his name was simply because the producers liked how Rowan Atkinson said it in the British TV series, Blackadder. It also has a similarity to the software "Microsoft Bob".
  • In the Definitive Mainframe Edition DVD box set, Michael Benyaer says he based his reading of "I don't think so" on a song by LL Cool J (which contained the same line).
  • The original Bob design received a noticeable change in the fourth season, the primary difference being more pronounced cheekbones.
  • Michael Benyaer was the original voice of Bob in seasons one and two. During the later portion of the third season, he was unavailable, having moved from the Vancouver area to Los Angeles. Veteran Mainframe voice actor Ian James Corlett voiced Bob in the later half of season three, with his only time voicing Bob's original design being a dream sequence in Number 7. As a throwback, Michael Benyaer returned to voice the original Bob during the flashbacks of the Daemon story, the fake Bob in the first half of My Two Bobs, and the real Bob in the second half. Michael is currently voicing Bob again in the new rebooted series ReBoot: The Guardian Code.
    • Bob's change in voice actors was canonized into the story, as Dot mentioned that the Benyaer-voiced Bob in season 4 (actually Megabyte in disguise) "sounded right" as opposed to Glitch Bob, voiced by Corlett.
