Michael Garibaldi, was Chief of Security for Babylon 5 from 2257 to 2261, Head of Covert Intelligence for the Interstellar Alliance for most of 2262 and from September 2262 onwards, was CEO of Edgars Industries.
During most of Babylon 5's five seasons, Garibaldi is the Chief of Security on board the space station Babylon 5. He holds the rank of Chief Warrant Officer. During the fourth season he suddenly resigned as Security Chief; he then begins working for Edgars Industries on Mars, one of the largest corporations on the planet. During the fifth and final season of Babylon 5 he was the Director of Covert Intelligence, a post similar to the present-day CIA Director, for the new Interstellar Alliance. Although friendly with the other crew members, he is very much his own man.
This independence leads him into great danger numerous times during the series. Like most of the characters on the series, Garibaldi is a complex person. On the positive side he is loyal, trustworthy, brave, shrewd, thorough in his job duties, and a tough and skilled soldier, with small arms, in hand-to-hand combat, or in the cockpit of a Starfury fighter. He possesses a lively sense of humor, enjoys watching old twentieth-century cartoons such as "Daffy Duck" (Duck Dodgers in the 24½th Century) who is referred to as a "household god of frustration" for Garibaldi in a conversation between Zack Allan and G'Kar, loves twentieth-century motorcycles, and generally has an easygoing, laid-back personality when he's not on duty.
However, he can also (ironically, given his suspicious nature) be too trusting of close friends and aides, and his tendency towards alcoholism and self-destructive behavior is a constant struggle for him throughout the series. Of the major characters on Babylon 5 Garibaldi is in many ways the most "down-to-earth" and "ordinary"; he often sides with the working-class humans on the station and in turn is considered by them to be a kindred spirit. He loves Italian food and often cuts secret deals with Babylon 5 dockworkers to bring expensive Italian foods onto the station. The deals are secret because of the disapproval of Dr. Stephen Franklin, B5's medical chief and a close friend of Garibaldi. Dr. Franklin disapproves of Garibaldi's love of fatty foods, although on at least one occasion he agrees to eat an Italian meal (bagna càuda) cooked by Garibaldi.
