Venom belongs to the Marvel Universe. DC has its own roster of characters, but Venom isn't among them. Marvel has developed the Venom storyline and character over time.
Honestly, it's quite uncertain. Venom's powers and characteristics might conflict with the established DC lore and superhero balance. But in a fictional world, anything could potentially happen with creative writing.
Another idea is that Greninja gets exposed to some kind of meta - human - creating substance in the DC universe and gains new powers. It could then join the Teen Titans, sharing its unique Pokémon abilities with the group. It would be interesting to see how Greninja interacts with characters like Robin, Starfire, and Cyborg, and how it uses its powers in battles against the Titans' enemies.
Definitely Naruto. His positive attitude and strong will could create a really interesting dynamic with Venom. He could either try to reform Venom or use its power for good in the Naruto world.
I think Spider - Man would be really interesting. Since in the comics, Venom has a long history with Spider - Man, and if you bring that into the Avengers' world, it could add a whole new layer of drama. The Avengers would be caught in the middle of their relationship, not fully understanding the complex history between them.
One idea could be a Venom crossover with Spider - Man in an alternate universe where they have to team up against a common enemy like Carnage. Another could be a Venom and Deadpool crossover, with their crazy personalities clashing and then somehow working together. Maybe a Venom crossover with the X - Men, where Venom's alien nature causes some interesting reactions among the mutants.
One possible storyline could be Venom getting involved in an Avengers mission. Maybe Venom's unique abilities like his symbiotic powers and super strength could be used to help the Avengers against a common enemy. For example, against a powerful alien threat that the Avengers alone can't handle. Venom's ability to blend into the shadows and his near - indestructibility could give the Avengers an edge in battle.
One common theme is the clash of ideologies. Venom has a more chaotic and anti - hero approach compared to the Avengers' heroic and morally upright stance. Another theme is redemption. Sometimes Venom is on a path to redeem himself through his interactions with the Avengers.
A crossover could work by having a common enemy. Let's say there is an entity that wants to take over both universes. Naruto and Agent Venom would meet while investigating this threat. They would find that their powers complement each other. Naruto's ability to create multiple clones could be used as a distraction while Agent Venom sneaks up on the enemy. Agent Venom's resistance to physical damage could also protect Naruto in dangerous situations. Their relationship could start off rocky due to differences in their personalities and fighting styles, but they would gradually learn to work together as they face greater challenges.
