He could get enhanced senses, like his spider - senses could become super - charged.
Maybe he'd gain some sort of new fighting style, mixing his acrobatic spider - moves with the grace of the Black Panther. He could also become more in tune with nature, which would be a new aspect for him compared to his usual city - based heroics.
Well, in a fanfiction scenario where Peter Parker eats the heart - shaped herb, it could potentially give him some new powers or abilities. Maybe it could enhance his spider - senses even further or give him a connection to some sort of ancestral energy like in the Black Panther's case with the heart - shaped herb. However, this is all just speculation within the realm of fanfiction.
Peter might get invited to the Avengers' headquarters. There, he could see all their cool gadgets and technology. He would be like a kid in a candy store. The Avengers could ask him for advice on how to deal with street - level threats, since he has more experience in that area. Peter would be really happy to contribute and feel like he's part of the team.
In such a fanfiction, Peter might lose his usual control. He could accidentally reveal his identity while drunk. For example, he might start talking about his Spider - Man adventures without realizing it.
In a 'Peter Parker meets Shuri' fanfiction, they could team up to fight a common enemy. Maybe a new super - villain emerges in both their worlds and they combine their unique skills. Peter with his spider - abilities and Shuri with her brilliant Wakandan technology.
Well, he might become extremely powerful. He could use the power of the gauntlet to protect his city in ways he never could before. Maybe he could even defeat the most powerful villains with a single snap.
He could be using his phone to track a villain's movements. Maybe he installed some special app on his phone that can detect unusual energy signatures. So while the teacher is droning on about history or math, Peter is secretly following the path of a super - villain who is on the loose in the city.
If Peter Parker joins the Avengers in fanfiction, it would change the team dynamics significantly. Peter is used to operating on his own in Queens, but with the Avengers, he'd have to learn to work as part of a much larger and more powerful team. He could introduce the Avengers to his street - level knowledge, which might be useful when dealing with villains who operate in the shadows. His relationship with Aunt May could also play a role, as the Avengers might need to protect her from any potential threats. Plus, his growth as a hero would be accelerated by being around such experienced and powerful teammates.
Perhaps Peter Parker gets invited to the White House for some sort of science fair or young innovators' event. There, he meets the president and they strike up an unlikely friendship. The president could then call on Peter for help in situations that require his unique skills, like dealing with a super - villain who has some connection to national security.
Well, Deadpool might crack a lot of jokes and make Peter Parker super confused. He could also try to team up with Peter to fight some villains, but his crazy methods would probably drive Peter nuts.
One scenario could be that the Avengers are facing a new threat that requires Peter's special skills. His ability to stick to walls and his enhanced strength could be crucial. Peter might also introduce a sense of youthful enthusiasm to the group. He could crack jokes during tense situations, which at first annoys some of the Avengers but later they come to appreciate it as a way to lighten the mood.
