The Green Goblin is very memorable. His maniacal laughter and his crazy stunts on the glider, along with his complex relationship with Spider - Man, make him stand out. He was one of the first major villains and set a high bar for the others.
Doctor Octopus is another great option. His mechanical tentacles and his high - level intellect pose a significant threat. You could write a story where he creates a new, more powerful set of tentacles that Spider - Man has to figure out how to defeat.
Well, the Kingpin could be a main villain. He could see Naruto as a threat to his criminal empire in New York. He might hire some ninja mercenaries from the Naruto universe to take him down. And then there's Electro, who could be enhanced by some sort of chakra - based technology. He could use his new powers to cause chaos in the city and target Naruto specifically, thinking that he's the key to getting even more power.
The Lizard could be turned into a more supernatural villain. Maybe he gets possessed by an ancient spirit that makes him not only stronger but also able to control other reptiles with dark magic. This would pose a huge threat to Spider - Man as he has to deal with the Lizard's new powers on top of his already dangerous physical abilities.
Venom is quite popular in Spider - Man fanfiction. His complex relationship with Spider - Man can be explored in many ways. He can be a villain, an anti - hero, or even an ally in some really creative fanfictions. Another popular one is Gwen Stacy. Fans love to write about her and Peter's relationship, especially in alternate timelines.
Some of the main villains in Insomniac Spider - Man 2 are Kraven the Hunter and Venom. Kraven is a formidable foe known for his hunting skills, and Venom brings his own unique set of challenges with his symbiotic powers.
The Vulture could be a new and more menacing villain. Maybe he's using the post - Civil War chaos to his advantage, stealing high - tech equipment that was left unguarded during the Avenger's split. He could be targeting Spider - Man specifically, seeing him as an easy target now that he doesn't have the full support of the Avengers.
Venom is another important villain. He has a symbiotic relationship with an alien entity. This gives him enhanced strength and abilities, and his hatred for Spider - Man makes for some intense battles in the graphic novels.
Well, he could protect villains in fanfiction by ensuring they get a fair trial. Spider - Man, being the morally upright hero he is, might believe that everyone, even villains, deserve justice. So he could protect them from vigilante attacks or mob justice until they can be properly dealt with by the legal system.
