Roadblock is a fictional character from the G.I. Joe: A real American Hero toyline, comic books and cartoon series. He is the G.I. Joe Team's Heavy Machine Gunner and debuted in 1984. He is one of the most prominent African Americans in the series.
Roadblock's real name is Marvin F. Hinton and he was born in Biloxi, Mississippi. His primary function in G.I. Joe is as a heavy machine gunner and a secondary function as a cook.
Before he enlisted in the U.S. Army, Roadblock wanted to be a gourmet chef, and was working as a bouncer to earn enough money to attend Escoffier School in France. An army recruiter managed to convince him that he could learn to be a chef in the Army. After enlisting, Roadblock found Army food appalling, and transferred to infantry where he excelled at using heavy weapons.
Roadblock is one of the biggest and strongest members of G.I. Joe, able to carry a fully loaded M2 Browning machine gun as a personal weapon, which can weigh up to 134 lbs, and usually requires a dedicated squad to transport and operate. Despite working in infantry, he still maintains his passion for making good food, and indulges in it while engaging in his secondary duty.
In the animated series, Roadblock is depicted as speaking in rhyme. He has a cousin named Heavy Duty.
