Roadblock, real name Marvin F. Hinton, is the tremendously strong, brave and loyal Heavy Machine Gunner for the GI Joe Team. Perhaps more than anyone, he believes in his role as an American Soldier. His personal weapon, the Browning M-2 .50 caliber HMG, weighs almost 150 pounds, and is generally crewed by THREE soldiers in the Army! Roadblock is also a skilled gourmet chef, and joined the Army originally because an Army recruiter convinced him the US Army could teach cooking just as well as the famed Escoffier School in France. Finding himself totally disgusted by KP duty in basic training, Roadblock transferred to the Infantry. At some point, he became acquainted or friendly with his future Joe teammates Duke and Flint.
Roadblock's first action with the Joe Team occurred when GI Joe Commanding Officer General Flagg was being laid to rest in Arlington National Cemetery after being murdered by Major Bludd. Cobra Commander learned of the full-dress funeral, and over Destro's objections sent the prototype "Rattler" ground attack jet to strike GI Joe while they were vulnerable. The plan would have succeeded, if Duke and Roadblock hadn't been present and armed-successfully downing the jet with their hand-held weapons! Joe Machinegunner Rock 'n Roll Stated: "You must be a new Joe, because if the bad-guys can hand-hold a .50-I quit!"
Danger Girl/G.I. Joe
After the acquisition of the Danger Girl, IDW was decided to first launch the characters under the IDW banner with a crossover with one of the major properties at IDW, G.I. Joe (as they are owned by the same company it seems possible that these characters exist in the same continuity, though this is never confirmed.) The series starts off with a dog chase involving Scarlett and Flint who are soon shot down. It is revealed that they were providing escort for a shipment of rediscovered missiles with great destructive power. They are soon shot down however and the missiles are taken by Cobra, who also take the two prisoners. Once in Cobra custody they come across Abbey Chase, who is acting undercover, though the two members of G.I. Joe do not know this. Elsewhere the American president arrives to the USS Flagg and informs the Joe team to stand down and to not seek to free their teammates. General Flag orders them to stand down. The remaining female members (Cover Girl, Lady Jaye, and Jinx) come up with a plan where they will contact the Danger Girl team (Cover Girl had previously met Johnny Barracuda.) The team shows up and exposes the U.S. President as Zarana in disguise. Soon enough it is revealed that the Danger Girl team already has an operative in place and she informs them of the plan. Firefly is to head to Moscow and detonate one of the missiles while Major Bludd is to go to Beijing to detonate another. Three teams head out, one to each of the two cities and the third to the Cobra base. By now Abbey is under suspicion of Baroness, Destro, and Cobra Commander and is captured by Zartan when she attempts to free Scarlett and Flint. While they are trying to escape a team of Low Light, Snake Eyes and Stalker arrive to free them. Meanwhile in Beijing a team of Jinx, Johnny Barracuda and Sonya Savage stop Major Bludd while a team of Sydney Savage, Cover Girl and Roadblock stop Firefly. It is soon revealed that there is another missile which is headed for the homing beacon which Zarana has placed on the USS Flagg. Silicon Valerie, Duke and Lady Jaye quickly deal with it. Meanwhile at the Cobra base, Storm Shadow has arrived to stop the Joes and he engages Snake-Eyes in combat. Eventually this group is also able to escape, while blowing up the base and they are all reunited on the USS Flagg.
