Something Sony may want to consider in their attempt to expand their cinematic universe (which is just Spider-Man & related characters) Is the story-line from the 1990's animated series titled "Spider Wars."
In that Series Finale, The Hob Goblin opens a dimensional portal and is wreaking havoc across parallel earths. Madame Web, enlists the aid of 4 different Spider-Men, as they exist in different versions on different earths to fight Hob Goblin.
If Sony ever does a version of this Shattered Dimension Story, they could introduce 3 other Spider-Men to their CU and perhaps do Spin-offs. Here are my suggestions for the other aspects of Spider-Man.
1. The Scarlet Spider, who was in fact a clone of Peter Parker.
2. Another incarnation of Spider-Man was the Iron Spider...
The Peter Parker of this world was a Billionaire inventor and had a suit much like Tony Stark's. He relied more on tech gadgets than his own Spider-strength.
3. Miles Morales (Ultimate Spider-Man)
I would introduce Miles Morales into this story-line instead of using a six armed mutate Spider-Man or a Doc-Ock Spider-Man. It would be a good way to get him started and accepted as a Spider-Man variant.
4. Current Sony Cinematic Universe "Amazing" Spider-Man would be the 4th aspect, of course played by Andrew Garfield.
Having this many Spider-Men in a movie would be a blast and could very well go up against the Sinister Six. That would even the odds a little more...
So what do you think?
