Charlie Robinson (Emerson Brooks) is a bomb analytics expert working for the FBI.
He and Angus MacGyver (Lucas Till) met while serving in the army as EOD (Explosive Ordnance Disposal) techs. On a two-week-mission in Kabul, they disarmed 127 IEDs together, setting a new record.
In Episode 1×06 (Wrench), Charlie calls MacGyver to New York. He needs Mac’s expert opinion on a bomb; suspecting that it has been made by a notorious bomb maker called “The Ghost“.
Over the course of the episode, they realize that The Ghost installs a digital camera into his bombs so he can watch as his victims try to deactivate the bomb and fail. As it turns out, the records go back over a decade – and there’s also a recording of MacGyver’s mentor Alfred Pena getting killed by one of the bombs in Afghanistan.
In Episode 2×12 (Mac + Jack), MacGyver and Jack Dalton (George Eads) are trapped in Mac’s house because The Ghost has rigged it with explosives. With the help of Charlie and Team Phoenix, they manage to disarm the bombs and get out.
In Episode 3×08 (Revenge + Catacombs + Le Fantome), Team Phoenix is approached by Eileen Brennan (Holland Roden), an Irish military intelligence officer; claiming she knows the whereabouts of The Ghost. Charlie joins Team Phoenix and Eileen to finally get hold of the bomb maker.
It’s later revealed that Eileen is the daughter of The Ghost who had killed her mother by accident. She only asked for the Phoenix Foundation’s help because she finally wanted to get revenge for her mother’s death.
In the Season 3 finale (Mason + Cable + Choices), Charlie is used as a pawn against Mac and his father James MacGyver (Tate Donovan). He sacrifices himself to save his friends and the guests of a fully-booked hotel.
