Well, the fanfiction could start with Naruto being in a strange place, like a different dimension where he encounters Venom. Venom, seeing Naruto's potential, decides to form a bond with him. This bond would bring out new powers in Naruto. He could use Venom's abilities, like the webbing and enhanced physical strength, in combination with his ninja skills. For example, he could swing from building to building in Konoha using the webbing while also using his shadow clones to confuse enemies.
In a Naruto Bonds with Venom fanfiction, perhaps Naruto is on a mission outside of Konoha when he stumbles upon an ancient artifact that contains the essence of Venom. Once it bonds with him, Naruto has to deal with the inner voice of Venom. The two start to communicate and understand each other. Naruto teaches Venom about his ninja way and the importance of protecting the village. In return, Venom gives Naruto the power to fight stronger opponents. They could team up against villains like Orochimaru who is now more powerful with some new dark magic he has acquired. This new bond would make Naruto an even more formidable ninja, but also a target for those who fear his newfound strength.
Naruto might become more aggressive at first. The influence of Venom could bring out his darker side. But as he gets used to it, he would learn to balance it with his usual positive and determined self.
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.
The plot might involve Naruto exploring the darker aspects of his world. Maybe he discovers a hidden organization within Konoha that has been dabbling in dark jutsu. This could lead to him having to make difficult choices between loyalty to his village and uncovering the truth.
At first, Venom might be angry at Naruto for neglecting it. But as the story progresses, Naruto could realize his mistake. Maybe he sees Venom helping the villagers in some way, like protecting them from a minor threat. This could make Naruto approach Venom and try to make amends. They could then start to train together, with Naruto teaching Venom about chakra and Venom teaching Naruto about its unique abilities.
Well, Naruto could be initially shocked by Venom's appearance. Maybe Venom would see Naruto as a worthy host at first, thinking his chakra could enhance its powers. But Naruto, being Naruto, would likely try to reason with Venom and convince it to use its power for good. They could end up teaming up against some common enemies in the Naruto universe, like the Akatsuki.
It could be about Naruto somehow ending up in the Venom universe and having to team up with Venom to fight a common enemy.
It could be an old ninja who was once banished from Konoha for using dark jutsu and now wants revenge. He might see Naruto as a symbol of the village he hates and tries to corrupt him by luring him into the darkness.
It could be a rogue scientist - ninja who has been experimenting with toxins and wants to use them to take over the ninja world. This antagonist would see Naruto's new - found bond with toxins as a threat to his plans.
One interesting plot twist could be that Venom starts to have memories of Peter Parker's life as Spider - Man. This would create a strange dynamic where Venom understands Spider - Man's motives on a deeper level and might even start to protect the things Spider - Man cares about. For example, Venom could find itself saving Mary Jane from a random mugger because it has a new - found sense of connection to Spider - Man's world.
In some fanfictions, Venom could be integrated by having a symbiote-infected character join the Avengers. Maybe a character like Spider - Man, who has a history with Venom in the comics, brings the symbiote's knowledge and power to the team. This could create new conflicts within the team as they deal with the more violent and unpredictable nature of the symbiote.
