He could have adventures in new dimensions. Maybe he discovers a dimension where his loved ones are alive but everything is in chaos, and he has to use his powers to restore order.
There could be a new scientist who helps Peter with his web - shooter technology. Maybe this scientist has some secret knowledge about the symbiote or other aspects of Spider - Man's powers. Another new character could be a foreign exchange student at Peter's school who turns out to have some sort of superpower or connection to the superhero world. Or it could be a new villain's henchman who later has a change of heart and helps Peter.
Well, one possibility could be Peter dealing with the public's new perception of him after the events in 'Far From Home'. Maybe he has to face more scrutiny from the media or the government. He could also be exploring new powers or trying to master the ones he already has better. Another aspect could be his relationships, like with MJ, Ned, or even new characters he meets in the fanfiction.
His relationships might become more distant. With the events of No Way Home, he's lost a lot and might isolate himself from his friends to protect them from any further harm.
They could go on a quest to retrieve a powerful magical artifact. Loki's knowledge of magic and Peter's agility and spider - sense would make them a great team. For example, they might have to travel to an ancient temple hidden in the mountains. Along the way, they face various challenges like traps set by an ancient race. Loki uses his magic to disarm some of the traps, while Peter swings them over dangerous chasms.
Well, in a fanfiction setting, there are many possibilities. One idea is that Peter might start to form a new superhero team. He realizes he can't do everything alone, especially after the events in Far From Home. He could recruit other young heroes he meets in the city, and together they could face challenges that are too big for just one hero. This would also give him a chance to grow as a leader and as a person.
Well, they might have an adventure in space. Maybe there's a threat out there that requires both Iron Man's advanced technology and Spider - Man's unique abilities. They could team up with other superheroes like the Guardians of the Galaxy. Peter would be in awe of the space settings, and Tony would be using his engineering skills to adapt to the new environment. Their father - son dynamic would add an interesting layer to the adventure, with Tony looking out for Peter while also relying on his help.
He might have enhanced technological skills. Since Pepper is associated with Stark Industries, Peter could have grown up with more exposure to advanced tech. He could potentially have better - integrated his web - shooters with other Stark - made gadgets, giving him new ways to fight crime. Maybe he could even have some sort of energy - based powers if he had access to experimental Stark technology from a young age.
Perhaps they embark on a diplomatic mission to a far - off land. Naruto as the Hokage and Hinata as his support. They would encounter different ninja clans and political situations, which would be a new experience for them. It would also test their relationship as they face various challenges together.
His Aunt May would be a crucial part of his support system. She's always been there for him, and in this tough situation, she'd offer emotional support, cook him healthy meals, and encourage him to keep fighting. Also, his friends like Ned could be there for him. Ned might help him with schoolwork when Peter is too tired from treatments or his superhero duties.
He could have the power of flight, which is not a typical spider - man power. As a demigod, he might be able to soar through the skies like some of the Greek or Roman demigods. Another power could be the ability to control the elements. Maybe he could use the wind to enhance his web - swinging or use fire to create a protective barrier around himself.
