Spider-Man 4 plot
Venom could be in hiding healing himself with the help of mysterio who is a top mental and technological scientist who helps Venom heal for the 4th it is revealed he was sent to jail by spiderman when he sabotaged a film set of which he was employed for a stunt.
and helps Brock survive the blast and the symbiote which needs items to survive Quintin beck and Brock have become friends he adopts the mysterio guise to destroy spider-man and save his friend
including manipulating people to bring them to his lair where the symbiote can absorb the chemical it needs to live from the mind of the victims as the mysterio gas helps boost the rate that chemical is produced
Spider-man finds mysterio's lair and they fight but venom is healed and helps the fight after venom is though to be defeated mysterio reveals his sinister plan he has found the symbiote is about to spawn and wants that symbiote as if venom dies so does the spawn he had to help him live mysterio is defeated before he can bond with this symbiote however
The Spawn has escaped, yes where a escaped criminal is on loose from a previous battle mysterio hid in a mental asylum however he unknowingly let out the killer Cletus Kasady who is on the run underground in the sub way he encounters the spawn accidentally it latches onto him and the film ends with a shadow of a mouth with weird teeth screetching in pain as a train passes by
by the way I meant to include Spider-man battled Mysterio and HE accidentally released Cletus Kasady
it's his fault the spawn and Cletus bonded well that's what he thinks he should have prepared himself also this give spidy the chance to interact with his next new villain for 5 this new foe could also put more strain on peter and Mary Jane especially when carnage's first or last victim is Gwen Stacy
well that's how she died in ultimate
