This is a list of characters from the animated television series ReBoot. Most ReBoot characters are named after technical computer terms or pieces of computer hardware. Main characters Bob Guardian 452 and the defender of Mainframe from both internal and external threats. Bob is often criticized by other Guardians for his unorthodox views regarding viruses: unlike other Guardians, who believe that viruses should simply be deleted on sight. Bob theorizes that viruses can be reprogrammed to live as Sprites (he cites Hexadecimal as proof of his theories). Despite this criticism, Bob is still respected as one of the finest Guardians ever to come out of the academy. Compared to Dot, he usually does things "on the fly", and is an extremely casual and laid-back hero in the first two seasons. After living and partially degrading in the harsh Web (under the alias "Interface") he became slightly more cautious, more sensitive and less impulsive than he used to be. Despite the difference in their personalities, he and Dot developed romantic tension that results them in coupling at the end of Season 3. He is equipped with a Guardian Keytool, "Glitch", which can transform into any device with a voice command. When a Guardian is first introduced to a Keytool, they exchange code. In Season 3 and 4, Bob bonds with Glitch (referred to in My Two Bobs as "Glitch-Bob") and gains energy-based Keytool powers. As Glitch was broken at the time and because Bob's code was missing from Glitch (Megabyte stole the code from Glitch before crushing it at the end of Season 2) the merger did not quite work. The continued use of his powers (including rebooting) lead to total fragmentation. Eventually they were separated; Glitch now upgraded in design and power regained his original form. While he was always in favour of non-violent solutions, in Season 4 he opposed to deletion of virals under any circumstances, which caused conflict with other characters like Matrix. The reasons for this change (as he had deleted viral Binomes by destroying ABC craft before) was not directly expressed on the show, but presumably it was the result of both Hexadecimal's reprogramming and his experiences of war-torn Mainframe. At the start of the "Code of Honor" webcomic, Turbo accuses Bob of causing a net-wide viral onslaught that has ruined tens of thousands of Systems, claiming his views have caused many Guardians to talk about
