I really hope they don't give Mary Jane powers. Can't we have one main cast member in Peter's age group who doesn't put on a costume or get powers ?
Although maybe Peter helps the other Spiders control their Symbiotes since he has the most experience with them.
The Avengers look fairly villainous as Symbiotes so maybe they can't control it while the Spiders can, which is where the fighting starts .I'm wondering if the Venomized heroes will somewhat maintain control of themselves. Peter, Miles, and Groot have part of their faces showing more than the other heroes. Especially Groot to the point you can see him smiling.
