A popular plot twist is when the Lizard turns out to be a pawn in a bigger scheme. Some other villain is controlling the Lizard's actions, and Peter has to figure out who it is while still dealing with the Lizard's attacks.
One popular plot twist is when the reincarnated Peter Parker has memories of his past life but discovers a completely different Spider - Man origin in this new world. For example, instead of being bitten by a radioactive spider, he might inherit the powers through some ancient family curse or a high - tech experiment gone wrong. Another is when he has to team up with his enemies from his past life, like Doc Ock, but they are now good guys in this new reality. And sometimes, the twist could be that Peter Parker is not the only one reincarnated. Maybe Aunt May or Uncle Ben also have memories from another life, which changes the whole family dynamic and how they interact with Peter as Spider - Man.
In some fanfictions, Peter's death might be a result of a long - term consequence of his superhero activities. For example, the constant use of his powers could have weakened his body over time, leading to a tragic end. It could also be that a new and unexpected enemy emerges, one that he underestimates and this ultimately costs him his life. The death then serves as a shock factor to drive the story forward, perhaps leading other characters to avenge him.
In some fanfics, like 'The Unexpected Ally', a plot twist could be that Venom actually has a hidden connection to Peter's family history. This completely changes the dynamic between them as they start to uncover secrets together.
The plot could twist when it turns out that the real danger the Avengers are in was set up by someone close to Peter. It could be a friend or a teacher who has been secretly working for a super - villain. Peter has to overcome the shock of this discovery and still find a way to save the Avengers.
One common plot twist could be that the kidnappers turn out to be working for an old enemy of Spider - Man who wants to use Peter to get to him. Another could be that the person behind the kidnapping is someone Peter thought he could trust, like a fellow student or a neighbor who has a hidden agenda. Maybe there's also a plot twist where Peter discovers he has a new power during the kidnapping situation that helps him escape.
Well, perhaps in the fanfiction, Peter's memories as an adult are still somewhat intact in his baby form. So he tries to communicate with his loved ones in his own baby - like ways, like making specific noises when danger is near or trying to write in a very clumsy way. This could lead to some really cute and interesting interactions.
There's a fanfic where Peter Parker tries to find a cure for the Lizard's condition. He teams up with Dr. Connors in his human form, and they work secretly in the lab. Peter uses his scientific knowledge from school and his experience as Spider - Man to try and reverse the effects of the experiment that turned Dr. Connors into the Lizard.
In some fanfictions, a plot twist could be Peter losing his powers and having to rely on his intelligence alone. For example, in 'Powerless Peter', he has to use his scientific knowledge to outwit villains. Another is when the alternate universe has Peter's loved ones turn against him. In 'Betrayed by Aunt May', Aunt May becomes a villain, which is a huge shock. And sometimes, Peter is from a different time period in the alternate universe, like in 'Peter from the Future', and that changes the whole dynamic of the story.
A good plot twist could be that Danny Rand turns out to be related to one of Peter Parker's enemies. For example, he discovers that he has a distant family connection to Norman Osborn. This would create a huge conflict for both Danny and Peter, as Danny has to figure out his own identity and loyalty while Peter has to decide if he can still trust his friend.
One interesting plot twist could be that Peter's spider - sense is affected by his new vampire nature. Instead of warning him of physical danger, it now warns him of approaching sunlight or the presence of vampire hunters. Another could be that his relationships with his friends and family change drastically. For example, he has to hide his new identity from Aunt May, but she starts to suspect something when he avoids going out during the day. Also, his friendship with Ned might be strained as he has to keep this huge secret.
