MacGyver

Angus "Mac" MacGyver is the title character and the protagonist in the TV series MacGyver. He is played by Richard Dean Anderson in the 1985 original series. Lucas Till portrays a younger version of MacGyver in the 2016 reboot.

In both portrayals MacGyver is shown to possess a genius-level intellect, proficiency in multiple languages, superb engineering skills, excellent knowledge of applied physics, military training in bomb disposal techniques, and a preference for non-lethal resolutions to conflicts. MacGyver works for the fictional Phoenix Foundation in Los Angeles, which in the original series was an independent think tank, and in the 2016 reboot is a clandestine government organization using the cover of a think tank. In addition to his scientific knowledge and inventive use of common items, he always carries a Swiss Army knife and refuses to carry a gun.
