Captain America: Serpent Society

Captain America: Serpent Society is an idea meant for the next film in the MCU Captain America series. In this hypothetical, the film would take place either at the very end of Phase 4 or at the beginning of Phase 5.

Synopsis
After Sam Wilson adopts the mantle of Captain America, he and Bucky Barnes must stop a criminal empire from forming a new "Hydra" known as The Serpent Society -- who plan on releasing an experimental virus and causing a global pandemic.

Plot Details
To start off, Sam’s arc revolves around the pressure of being the leader of the new supers (again, assuming this film takes place right after an Avengers film). The press insulting him, every action of his being over analyzed and judged, and him feeling the pressure of being a black Captain America. While Bucky, we can explore him trying to figure out where he wants to go with his life now that he’s finished his notebook. What does he do with his life now that he’s free?

I would like Sam and Bucky to stay as a duo (I imagine they ended up moving in together), they're just so interesting and funny together. Then we'd also have Misty Knight and Joaquín Torres as support. Torres comes in (this film will be his first time suiting up) to help out Sam, while Misty comes in, sent by Nicky Fury (as a ground agent of S.W.O.R.D.), and her and Sam develop a relationship reminiscent of Steve and Natasha.

Shortly after Sam’s speech in New York, a company called Serpent Solutions rose up, helping those hurt and displaced from the Blip. Years later, the world has returned much to normality and a rare period of peace between nations has sprung.

Serpent Solutions is a fake pharmaceutical company, run by Arnim Zola himself, still alive after the events of CA: The Winter Soldier. Supplied and funded by A.I.M., an advanced science and technology conglomerate. Serpent Solution's plan is to drive the superheroes out and reclaim control of the government by diving America as they supply arms and technology to radicals and subversive organizations in order to foster a violent technological revolution.

Serpent Solutions is seeking out Devil's Breath, a virulent bioweapon that reads specific DNA and can effectively wipe out ‘super powered’ individuals. Currently being worked on by Dr. Bernhold Renner, former S.H.I.E.L.D. scientist and lead researcher at Serpent Solutions -- Sam, Bucky and the others must work together to stop the bio-terrorist organization from releasing the experimental virus and causing a global pandemic.

Henry Gyrich (played by Demetrius Grosse; a former government official turned business man who has a hatred for superheroes and liked when the government had the power) is the face and public CEO of Serpent Solutions, although he is a pawn, being used by the real leaders, Arnim Zola and William Burnside (obsessed with Steve Rogers, doesn't think Sam deserves the mantle and wants to get rid of the "false capes"), known as the Grand Director.

Serpent Solutions has their own specialized task force to take down heroes -- Serpent Society.

The all female group includes;


 * Claudette Voorhees aka Madame Cobra; a former Red Room spy (genderbent) and the leader of the Serpents. Has electrically-charged, Carbonadium chain-whips.
 * Rachel Leighton aka Diamondback; former S.H.I.E.L.D. operative. Enhanced Knifeman equipped with diamond encrusted Carbonadium nails, knives and daggers.
 * Ophelia Sarkissian aka Viper; former Hydra assassin. A master toxicologist who specializes in poisons and toxins.
 * Tanya Sealy aka Black Mamba; former Ten Rings member. Has tiny nanites that join together with each other to form various structures and constructs.
 * Cornelia Stokes aka Cottonmouth; rogue Wakandan (also genderbent) and former follower of Killmonger. Has the power to emit a sonic scream.

The Serpent Society are all equipped with Carbonadium weapons.

Trivia

 * I imagine the movie takes place either around the Forth of July, or in November during an election year. Just depends on the direction you want to take it. If you go the latter route, I would like Norman Osborn to be one of the presidential candidates.
 * I want the same vibe as Thor's Revengers from Ragnarok, Sam having Bucky, Torres and Misty as his 'Team Cap '.
 * While Sam and Misty have a flirtatious relationship, he has no solidified love interest in the film. I'd much prefer if the MCU would finally let a main character be gay and have Sam/Bucky happen.
 * Misty Knight will not have a metal arm in the film.
 * I’d like if Bucky got his cat, Alpine.
 * Sharon Carter is not in the film.
 * Serpent Solutions is very similar to Umbrella from Resident Evil if you’re familiar with that series.
 * S.S. is an analogy of MAGA, their prejudice view of America and how those views can lead to destruction.
 * Devil's Breath is an aggressively volatile and powerful poison tailored to destroy the body of anyone with metagene DNA.
 * Carbonadium is a highly resilient, radioactive metal developed by A.I.M. by fusing the compound of Vibranium with alien technology.
 * Henry Gyrich is a black man being used as the face of Serpent Solutions for positive press, secretly being run by Arnim Zola and William Burnside.
 * Depending on if you want to keep old stuff or start incorporating new things, Arnim can be replaced with MODOK.
