Well, it depends on the creativity of the fanfiction writer. One possibility is that the field trip is to a magical museum. In this museum, there are artifacts that have the power to show the past of Hogwarts and its founders. The students might accidentally set off one of these artifacts and be sent back in time, having to find a way to return to their own time while not changing the past too much.
In fanfiction, during a Harry Potter field trip, students might encounter new magical creatures not in the original books. For example, they could come across a herd of rainbow - colored unicorns in a hidden glade. They may also visit a wizarding village that was never mentioned in the main series and learn unique spells from the local wizards there.
In a field trip to Avengers Tower fanfiction, the students could be given a tour by Black Widow. She could show them the training facilities and tell them stories about her missions. They might also get to see the Avengers' living quarters and learn about their daily lives. This would be a great opportunity for the students to get an in - depth look at the world of the Avengers.
In a fanfic about a Spiderman field trip, it could be that the field trip is to Oscorp. There, Spiderman discovers some unethical experiments. He has to then figure out how to expose the wrongdoings without revealing his identity to his classmates who are also on the field trip. He might use his wits and web - slinging abilities to gather evidence secretly.
Peter might be in awe of all the high - tech gadgets in Stark Tower. He could meet some of the Avengers unexpectedly and have a short chat with them. Maybe he'd even get a chance to see Tony Stark's personal workshop up close.
He might encounter a strange creature. Since Peter has a penchant for getting into extraordinary situations, it's not far - fetched that during his field trip, he stumbles upon a creature that no one else has seen. Mary Jane could be the first person he tells, and together they decide what to do about it.
Peter could be amazed by Wakanda's advanced technology. He might see the vibranium mines and learn about how they use vibranium in different applications. Maybe he'll even get to meet some of Wakanda's superheroes like Black Panther and exchange some spider - themed and panther - themed combat techniques.
There could be a mystery on the base that Peter, with his sharp senses and quick thinking, is the only one who can solve. Maybe there are some strange disappearances or unexplained phenomena that turn out to be related to some new experiment gone wrong, and Peter uses his superhero abilities and intelligence to figure it out.
Well, Peter could encounter a strange scientific anomaly during the field trip. Maybe he discovers a new form of energy that no one has ever seen before. He would then use his Stark - like intelligence to try and understand it, and perhaps even come up with a way to harness it.
In a 'Dragon Ball Field Trip' fanfiction, the characters might go on an adventure to a new planet. For example, Goku could lead the Z - fighters on a field trip to a planet known for its unique martial arts training. They could encounter new species and learn different fighting techniques there.
It could also be a new generation of students. For instance, the children of the original characters. They might go on a field trip to explore an ancient wizarding ruin. During the trip, they discover secrets about their parents' time at Hogwarts and how it relates to the ruin they are exploring. This would add a new dimension to the Harry Potter universe in the fanfiction.
Maybe they could visit the Kai planet. Goku would be thrilled to meet the Kais again. He could learn new techniques from them. Vegeta might be jealous at first but then get interested in learning too. The other characters like Trunks and Goten could explore the beautiful landscapes of the Kai planet and have some friendly sparring matches with the Yardrats who live there.
