Batman, initially cautious, realizes they could work together. They team up to take on a new villain who has a blend of high - tech gadgets and super - strength.

And Venom's desire to spread chaos and destruction would put both heroes in a difficult situation.
The Joker could be a great main antagonist. Imagine he teams up with some of Spider - Man's foes like the Green Goblin. They could create a chaotic plan to take over both Gotham and New York. Their combined madness would be a huge threat to both Batman and Spider - Man.
