Savage and Hyneman are the original MythBusters, and initially explored all the myths of the series using their combined experience with special effects. The two work at Hyneman's effects workshop, M5 Industries; they make use of his staff, who often work off-screen, with Hyneman and Savage usually shown doing most of the work at the shop. The show is narrated by Robert Lee, though in some regions his voice is replaced by a local narrator.

As the series progressed, members of Hyneman's staff were introduced and began to appear regularly in episodes. Three such members, artist Kari Byron, builder Tory Belleci and metal-worker Scottie Chapman, were organized as a second team of MythBusters during the second season, dubbed the "Build Team". After Chapman left the show during the third season, Grant Imahara, a colleague of Hyneman, was hired to provide the team with his electrical and robotics experience. Byron went on maternity leave in mid-2009, with her position on the Build Team temporarily filled by Jessi Combs, best known for co-hosting Spike's Xtreme 4x4. Byron returned in the second episode of season eight. The Build Team now works at its own workshop, called M7, investigating separate myths from the original duo. Each episode now typically alternates between the two teams covering different myths, although the two teams still work together.

The series had two interns, dubbed "Mythterns": Discovery Channel contest winner Christine Chamberlain and viewer building contest-winner Jess Nelson. During the first season, the program featured segments with folklorist Heather Joseph-Witham, who explained the origins of certain myths, and other people who had first-hand experience with the myths being tested, but those elements were phased out early during the series. The MythBusters still commonly consult with experts for myths or topics for which they need assistance. These topics include firearms, for which they mostly consult Lt. Al Normandy of the South San Francisco Police Department, and explosives, for which they consult retired FBI explosives expert Frank Doyle and Sgt. J.D. Nelson of the Alameda County Sheriff's Office. The MythBusters often ask other people, such as those supplying the equipment being tested, what they know about the myth under investigation.
