The successful first season of Marvel and Netflix’s Daredevil not only jump started plans for a second season, but also firmed up the streaming service’s commitment to building their street-level pocket of the Marvel Cinematic Universe. We know that Jessica Jones will arrive later in 2015, with Luke Cage debuting in 2016, and Iron Fist and The Defenders still to follow.

Luke Cage will star Mike Colter as the title character (and erstwhile Power Man), who will be introduced in Jessica Jones. So far, that’s all we really know about the series. Anything else – including the assumption that, like in the comic books, Cage and Jessica Jones will be married and have a daughter – is all speculation. Now we can add one more rumor to the mix regarding a potential villain.

According to Heroic Hollywood (via CBM), a villain from the early Power Man comic books will make an appearance: the drug lord Cornell Cottonmouth. There are no additional details or source available, and we don’t know in what context the villain could appear in relation to the still-unknown nature of Luke Cage‘s overall plot, so take this with a grain of salt, as always.

There have been a couple of different villains called Cottonmouth, but the one named Cornell first appeared in Power Man #18 in 1974 as a drug dealer who crossed paths with Luke Cage – then known as Carl Lucas – when Willis Stryker (also known as the villian Diamondback) stole a shipment of Cottonmouth’s drugs, intending to frame Cage. Cornell Cottonmouth possessed super-strength rivalling that of the invulnerable Cage and a mouth full of razor-sharp teeth.

If Cornell Cottonmouth really does appear as a central villain, the character could also serve as a bridge between Luke Cage and Iron Fist. In later comics Cottonmouth goes to work for the villain Nightshade, and at one point the storyline sees Cage and Iron Fist pitted against each other. More likely, Cottonmouth might emerge in the Netflix series as a crime lord looking to move in on the incarcerated Kingpin’s Hell’s Kitchen territory.

So far, the only concrete plans for Marvel’s Netflix continuum revolve around Daredevil and Jessica Jones. With all the series expected to cross over at some point, we know that Charlie Cox’s Daredevil will have his hands full dealing with Jon Bernthal’s Punisher. Certain aspects of the Iron Fist comic book were teased in Daredevil season 1, but we may end up seeing some of those plot threads played out in Luke Cage. Stay tuned for more details as they emerge.

Daredevil is currently available on Netflix. Jessica Jones premieres in fall 2015, followed by Luke Cage and Daredevil season 2 in 2016.
