Interesting, but because of the way we set up Shocker I think we can lean a little more towards the criminal element than what you're proposing, as well as trim down the number of movies we need to set up a number of these villains.
Here's my proposal: OsCorp is the Arc Villain...but not for the reasons you think.
Alright, it's established that in our scripts that A) Peter has dealt with the Chameleon, B) Herman decided to attack a subsidiary of OsCorp, C) Shocker has a plan to take over the prison, and D) the Shocker gets recruited for another initiative in prison. In addition we know that in the comics that E) in the Ultimate Peter's powers were tied to an attempt at creating the Super Soldier Serum (made by OsCorp), F) in that same continuity, Richard Parker had been one of the scientists working on an [unrelated] Super Soldier Project, G) Peter's parents were spies (616), H) Peter's parents were assassinated (616), I) Chameleon was taught by the man who killed his parents (616), J) Kraven and Chameleon are half-brothers (616), K) Kraven's family has a thing against Spider-Man and his allies...
Now that we have all of that together, let's start building up a story of Criminals, Espionage and Corporate Sabotage using that information.
Spider-Man 2:
Starting with that Post-Credits sequence where Shocker is approached by a recruiter [who so far hasn't been tied to anybody], ask that he keep an eye on Dmitri (Chameleon). Next, we move to Kraven, who as a higher up in the Solntsevskaya Bratva [Russian Mafia], hearing about his brother's capture. Now, there's no love lost between the two brothers, but there's honor,
family honor, at stake here, so Kraven asks two of his own, Aleksei Sytsevich [Rhino] and Adrian Toomes [Vulture] to learn what they can about the "
Pauk" [Spider]. Their first stop is getting into contact with Dmitri [through a backdoor prison channel to keep their names clear] about what he knows about the Spider, where he gives a rather detailed, and well reasoned, impression of Spider-Man; unknown to the three, this communique is tapped by Herman who grins with a bit of satisfaction.
From here, start building up the idea that Kraven and his brother were where they were at in the Bratva hierarchy wasn't just because they were violent thugs with a sense of intelligence, but because of their prior ties to the KGB and the secrets, tech and blackmail they could level at people with little effort on their parts; simultaneously, Peter's uncovering family secrets via his parent's effects, finding that they were Government Contractors due to their positions in OsCorp, a defense contractor to the US Military, with references to a formula. But it ultimately isn't until the end [after the B-Story involving Herman and Dmitri's war for control over the prison that ends in Herman's favor], that things line up for us and the audience learns that they [the Kravinoff brothers],
specifically, were the reason his parents were assassinated, that Peter was left an orphan, that we get to get our first glimpse of Peter's
rage.
In this rage, and against the advice of all his friends and family, Peter makes a beeline for Kraven. What he fails to understand, is that in those many years Kraven and his cadre weren't idle with the technology and formulae they stole from the Parkers, created weakened versions of the prototype formula [that eventually created Peter]; it's why, when he's confronted by a fully kitted out Rhino and Vulture, they can stand reasonably toe-to-toe with Spider-Man. He struggles, eventually overcoming them, but then has to face Kraven in his full glory. The fight is absolutely brutal, and it's only a reminder of Uncle Ben that snaps him out of his rage, letting him finally fain an upper hand.
B-Plots:
- Herman taking over Riker's, first by taking out Dmitri. Loses to Kraven when he finally shows up.
-- "You are but an animal trapped in this cage, with I
, the
Hunter!"
- Felicia's estranged father, Ivan Hardesky, part of Kraven's Bratva and this series' Tinkerer.
-- When he fails to work fast enough and fearing he is a turncoat, Kraven forces Ivan to test the formula on his daughter, tying it into why Peter confronts Kraven the way he does.
- News about Astronaut John Jameson returning to Earth after the successful first test flight of a private aerospace vehicle (OsCorp) and the recovery of alien material.
Post-Credits: Norman Osborn, having managed to
finally [after all these years] repossess the technologies stolen from OsCorp, gives them over to his team of scientists overseeing the project; Kurt Conners, Michael Morbius and Miles Warren, as overseen by Project Lead Otto Octavius. In the background, we see the creation of a Venom symbiote from the acquired alien material.
Spider-Man 3: TBD
Need to see what we actually agree on what the sequel should be, but I figure having Venom the main antagonist/deuteragonist works here, maybe having Morbius and the Lizard as secondary villains. Tease the Clone Saga, Gwen as Spider-Woman, and/or Green Goblin here.
From what I could gather, because Sony has the rights to all Spider-Man properties [for film distribution], if Marvel was to make a movie about Jessica Drew as Spider-Woman they'd have to either come to the negotiation table or pay for licensing of Spider-Woman in the title.
But that's specifically her, Julia Carpenter, Mattie Franklin, and Mayday Parker are all fair game for us [and Gwen, in two years].
