Bob As Guardian 452, Bob's chief function is to defend Mainframe from the plots of viruses such as Megabyte and Hexadecimal, and to help its inhabitants win games. He wears Glitch, a multi-function guardian keytool, on his left arm. Bob is rather impulsive and overconfident, which sometimes gets him in trouble with Dot. He has an old car he works on in his spare time, and lives in Kits sector near the waterfront, named for Kitsilano, a waterfront district in Vancouver, where ReBoot is produced. Not a native of Mainframe, Bob hails from the Supercomputer.
She runs Dot's Diner, a retro-style eatery on Baudway frequented by binomes. Dot sometimes wears glasses, and is something of a workaholic. She can even sing! Dot tends to think things through thoroughly before taking action, which can irritate Bob and Enzo, and is very independent. A successful businesswoman, Dot is always on the lookout for new opportunities.
In seasons 1 and 2 he almost always wore a red baseball hat, and two of his favorite games were Jet Ball and Circuit Racing. He went to school (or at least classes), where he hated studying ancient languages like COBOL and FORTRAN. He was featured in the episode "Enzo the Smart," and underwent a minor upgrade in "Talent Night" and a major one in "Icons," when he began calling himself Matrix.
AndrAIa is the first game sprite ever to appear outside a game; we first saw her in the episode "AndrAIa." She's the only sprite in Mainframe the same age as Enzo. Andrea Libman provided the voice of AndrAIa in episodes 19 through 27; Sharon Alexander began providing her voice in "Icons," in which she underwent a major upgrade.
His body is made of blue armor, and he has a suave but diabolical voice. Megabyte is a virus and controls an entire sector of Mainframe, Sector 1000, but is always trying to break out of the city and access the Supercomputer. He lives in a tower called the Tor and has his own huge following of binomes, which can be recognized by their blue color, green eyes, and "unhappy face" emblem, just like Megabyte himself.
The old computer guru made of gold metal. He looks like a robot, and lives in the Principle Office in the center of Mainframe. Phong is the oldest sprite in Mainframe and, as its Command.com, has access to all its vast knowledge. However, one must usually beat him at Pong, his favorite game, before he will give out advice. His icon is a yin-yang symbol. Phong shading is a technique used in computer graphics to render polygons.
She is a virus and lives on an island called Lost Angles, and was featured in the episode "The Medusa Bug." In the episode "Gigabyte," we learned that Megabyte is her brother. Hexadecimal controls the nulls of Mainframe.
Bob's TV set. He hardly ever shuts up, which causes Bob (and everyone else) frequent irritation. Featured in the episode "Wizards, Warriors, and a Word from our Sponsor."
Enzo's dog, red and gold. About as big as Enzo and takes orders only from him. Featured in the episode "In the Belly of the Beast."
