Well, one possibility could be that Venom, being an anti - hero, is initially seen as a threat by the Avengers. But then they realize that there's a greater enemy that they both need to face. Maybe an alien force that is immune to the Avengers' usual attacks but Venom's symbiotic abilities can somehow counter. So, they reluctantly team up, with Venom constantly trying to assert his own way of doing things, leading to some interesting clashes and character development within the team - up.
In a Venom X Avengers crossover fanfiction, the story could start with Venom causing chaos in a city. The Avengers are called in to stop him. However, during the fight, they discover that Venom is being controlled by a powerful psychic. This psychic also has a plan to take over the minds of the Avengers. So, instead of fighting Venom, they decide to help him break free from the control. Once free, Venom, out of a sense of honor or maybe self - preservation, decides to team up with the Avengers to take down the psychic.
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.
One possible plot could be that Venom somehow gets transported to the Naruto universe. He might initially be seen as a strange and powerful beast. Naruto, being the curious and friendly ninja he is, tries to communicate with Venom. They could end up teaming up against a common enemy like Orochimaru who is interested in Venom's powers for his own dark experiments.
Well, it could be that Venom somehow gets transported to the Star Wars universe. Maybe he lands on a planet like Tatooine and causes chaos among the local gangs. The Sith could be interested in his power and try to control him, but Venom is too wild. And the Jedi might sense his dark presence and have to decide whether to destroy him or try to redeem him.
One possible plot could be that Voldemort teams up with Loki. The Avengers and the Hogwarts crew would then have to work together. Harry, with his knowledge of magic, could teach the Avengers some basic spells to counter the dark magic Voldemort and Loki are using. Iron Man could use his technology to enhance some of the Hogwarts defenses. And Thor could share his knowledge of Asgardian magic with the wizards at Hogwarts.
One idea could be Venom bonding with Hulk. Imagine the power boost and the chaos they could cause together. Another is Venom facing off against Thor. The contrast between Thor's godly powers and Venom's alien abilities would make for an exciting battle. Also, Venom could team up with Black Widow and use his stealth and her combat skills for some undercover missions.
Well, perhaps in this fanfiction, there's a multiverse rift that pulls Nightwing into the Avengers' world. The Avengers initially mistake him for an enemy, but after some misunderstandings are cleared up, they realize his skills. Together, they face a new threat created by a combination of Hydra and some of Nightwing's rogues gallery who have also crossed over. Nightwing could teach the Avengers some stealth tactics while they show him how to handle more powerful cosmic threats.
One possible plot could be that the Shikon Jewel gets scattered across the Marvel universe. Inuyasha and his friends, like Kagome, have to team up with the Avengers to retrieve the pieces. Iron Man might be intrigued by Inuyasha's sword and try to study it, while Captain America could admire Inuyasha's fighting spirit. They'd face villains who also want the power of the Shikon Jewel, creating an epic adventure.
One possible plot could be that the Voltron team gets transported to the Avengers' universe. They might initially be seen as threats, but then they realize they need to team up to fight a common enemy, like a powerful alien force that's too much for either group alone. The Voltron lions could combine in the middle of New York City, creating an amazing spectacle.
A really interesting plot could be a time - traveling crossover. Supergirl goes back in time to the era of the original Avengers. She helps them in a battle that changes the course of history. In return, the Avengers help her find a way back to her own universe. During this time, she forms a special bond with Thor, as they both have superhuman strength and a connection to otherworldly powers.
