“Look out, everybody, things are about to get awesome!”
Marcus is a merchant character with next to no morals. He is also extremely aggressive towards his rival arms dealers going as far as to have them killed or have their stock burned. Indeed, in Borderlands 2, his vending machines say that he "made sure of that." Marcus also has a very strong "no refunds" policy; in his intro cutscene in Borderlands 2, he is seen shooting a customer asking for a refund with what he claimed was a defective gun. Despite this, he is not above thanking people who do things which turn out well for him.
Despite his aggressive business dealings, Marcus is shown to be very acquainted with the Vault Hunters. After Roland's death, Marcus is visibly saddened, despite their arguments over his business, specifically Marcus supplying bandits with weapons. Later in the storyline, he gives the Vault Hunters a free weapon, not because Hyperion is disrupting his arms trade, but because Handsome Jack is a "greedy murdering sonofabitch who needs to die screaming."
Marcus was originally an arms dealer allied with either the Dahl or Atlas corporations before the Vault Hunters made their way to the planet. His current affiliations are unknown, although he maintains a mercenary outlook on life, which has him dealing frequently with the main characters. He sells weapons from all except the Eridian and Gearbox weapon manufacturers. During Borderlands he is the only current purveyor of weapons, while in Borderlands 2 he is the only non-Hyperion weapons purveyor. Despite his numerous weapon vendors and advertisements for his business, it is written in very small text, on his vendors that he is in fact, "unauthorized" to sell weapons on the planet.
It is also hinted that Marcus also sold daily supplies to Pandora residents, as he is the first person to be suspicious of where Patricia Tannis's supply comes from, due to the fact that she never buys from him.
Marcus is the driver of the bus that brings the original four Vault Hunters to the town of Fyrestone at the beginning of Borderlands. After the Vault Hunters complete some tasks around Fyrestone, Marcus opens up his weapon and ammo vendors in the town. He runs and maintains the weapon and ammo vendors found throughout Pandora. Marcus himself lives in New Haven, and offers a few optional missions when the Vault Hunters arrive there.
In Mad Moxxi's Underdome Riot, Marcus is revealed to have been Mad Moxxi's third husband. While he does not personally appear in that DLC, he still provides his services to the Vault Hunters, such as with the new Marcus Bank.
Between the events of Borderlands and Borderlands 2, Marcus moved to Sanctuary at Roland's request. However, he sells weapons to both the Crimson Raiders and Bloodshots, the latter treating him like a god and having created a shrine at Bloodshot Ramparts, despite Roland's insistence that he doesn't.
