I definitely don't see Venom popping up this Trilogy, but it would be nice if they do the same with him, that they are doing with Green Goblin right now, when they make a new Trilogy. Build his character during the course of 3 Movies.
Exactly.
and they can still keep there "Oscorp" ties within that new trilogy if they tie the symbiote in with Richard Parker, like in USM.
I always had an idea of Oscorp (Richard and Eddie Sr. particularly) being contracted by the government to experiment on the Symbiote to find medical and military applications but when Eddie Sr. deemed it to dangerous and put it on ice, out of the reach of the Norman, he disappeared like Richard would later do.
Years later, Eddie Jr. is looking for answers like Peter was in the previous trilogy. He enlists Peters help and they discover the symbiote. Peter takes a piece for his own experimentation and the typical story for him happens. It attaches itself to his suit and it corrupts him.
IMO, the story should see everything in Peter's life crumble because of it (alienates and pushes away his loves one, he becomes a menace in the yes of the media, etc). Peter decides its time for it to go.
Meanwhile, Eddie does his digging and finds out what Oscorp did (I say from Norman himself) and vows revenge.
Typical church scene happens where the Symbiote leaves Peter and goes to Eddie who vows to take out everyone responsible.
Peter follows his path of destruction, while dealing with his mindgames, and this leads to their confrontation.
you get the gist.
