Marcel was bitten by the Enhanced Original Vampire, Lucien Castle, but was cured by Vincent Griffith using the serum that turned him into the Beast, an upgraded Original Vampire. He then took over New Orleans and established his rule over the supernatural community.
In “The Originals,” Marcel Gerard, a vampire sired by Klaus Mikaelson, undergoes significant transformations throughout the series. Initially, Marcel is the self-proclaimed king of New Orleans, having taken control of the city during Klaus’s absence. His rule is characterized by a strict code and a system that ensures peace among the supernatural factions.
The pivotal moment for Marcel comes in the third season when he is fatally bitten by Lucien Castle, who has become an Enhanced Original Vampire, a creature even more powerful than the Originals themselves. This bite is lethal to vampires and werewolves alike, and there is no known cure at the time. However, Marcel’s fate takes a dramatic turn when Vincent Griffith, a powerful witch and ally, intervenes. Vincent uses a serum that was created by the Strix’s coven of witches to turn Marcel into the Beast, an upgraded Original Vampire prophesied to be the downfall of the Mikaelson family.
Upon taking the serum, Marcel not only survives the bite but also becomes the most powerful creature in the vampire lore, surpassing even the Original Vampires. With his newfound power, Marcel seeks revenge against the Mikaelsons for their past betrayals and for the death of Davina Claire, a young witch he considered family.
Marcel’s ascension to the Beast leads to a significant shift in power dynamics within New Orleans. He challenges the Mikaelsons, leading to a series of conflicts that culminate in his taking control of the city once again. Throughout the rest of the series, Marcel’s role fluctuates between antagonist and ally as the narrative evolves, with his relationships with the Mikaelson family, especially Klaus and Rebekah, being central to his character development.
By the end of the series, Marcel has reconciled with the Mikaelsons to some extent and has found love with Rebekah. He continues to be a formidable presence in New Orleans, upholding his vision for a city where supernatural beings can coexist peacefully.
