In some fanfictions, Ultron might team up with one of Spider - Man's villains, like the Green Goblin. They could create a plan to take over New York. Spider - Man would then have to face this powerful alliance. He might seek help from other superheroes he's associated with, like Iron Man or Daredevil, to combat this new threat.
A really cool concept could be Ultron creating robotic versions of Spider - Man's villains. So instead of fighting the normal Doc Ock or Vulture, Spider - Man is up against robotic and enhanced versions of them. This would be a huge challenge for him as these robotic villains could have new abilities and be more difficult to defeat.
Spider - Man could use his agility. He could quickly dodge Ultron's attacks and find a weak spot in Ultron's armor. Since he's so fast and nimble, he could get in close and plant some sort of disabling device he made with his scientific knowledge.
Well, a fanfiction might explore Spider - Man's relationships within the Avengers during Age of Ultron. He's the new guy, so there could be some tension or bonding moments. For instance, he could have a heart - to - heart with Captain America about what it means to be a hero. Or he could have a friendly rivalry with Thor, competing to see who can take out more Ultron bots in a given time.
One interesting plot twist could be that Ultron hacks into Spider - Man's suit. This would put Spider - Man at a huge disadvantage as Ultron could control his movements or disable some of the suit's functions.
One great storyline could be Spider - Man trying to prove himself to the Avengers during the Age of Ultron chaos. He might start off as an underestimated newcomer but then show his true worth by using his unique abilities like his spider - sense to detect Ultron's minions before the others. Another could be a story where Spider - Man has to rescue a captured Avenger from Ultron, using his agility and web - slinging skills to outwit Ultron's defenses.
In a Spider - Man vs Ultron fanfiction battle, Spider - Man has a good chance of winning. He's extremely agile and has his spider - sense which can help him avoid Ultron's attacks. His web - slinging also gives him an edge in mobility.
Mysterio would be an interesting villain for this fanfiction. He could use the chaos of the Age of Ultron to create illusions that further disrupt the city and make it difficult for Spider - Man to tell what's real and what's not. He might also be able to trick the Avengers into believing false threats, causing internal strife within the team.
Spider - Man could fit in as an unexpected ally. He could be in New York when the chaos of the Age of Ultron starts spreading there. His knowledge of the city's layout and his ability to move quickly through it could be very useful. For example, he could help evacuate civilians while the Avengers are fighting the bigger battles against Ultron's forces.
One interesting crossover is 'When Worlds Collide'. In this fanfiction, the universes of Iron Man and Spider - Man somehow get merged. This leads to some really unique situations, like Spider - Man having to deal with Iron Man's high - tech world in a whole new way. Another is 'The Tech - Web Alliance'. Here, they form an alliance to fight a villain who is using both high - tech and some sort of web - related powers. It's a really cool concept that combines their two skill sets.
One interesting crossover could be Naruto's chakra system being studied by Spider - Man 2099's advanced scientific mind. Maybe he could find a way to use chakra - like energy in his web - slinging or combat. Another could be Naruto teaching Spider - Man 2099 some of his ninja skills, like stealth or hand - to - hand combat techniques. And a really wild one could be a fusion of their powers, where Spider - Man 2099 has some of Naruto's nine - tailed fox power in his enhanced form.
One interesting crossover could be where Spider - Man finds himself in the Twilight world. Maybe he has to deal with the vampires and werewolves while trying to keep his identity a secret. He could use his web - slinging skills to navigate the forests of Forks.
