They might have adventures exploring different planets. Peter's charm and Rocket's combat skills would make them a great team. For example, they could be on a mission to find a rare artifact on an uncharted planet. Along the way, they'd face various challenges like hostile aliens and dangerous terrains.
They might go on a mission to find a rare herb in a dangerous forest. Naruto's determination and Anko's knowledge of the area could lead them to the herb and also encounter some interesting creatures along the way.
They support each other emotionally. Peter is a great listener when Rocket wants to rant about something. And Rocket is there to give Peter a reality check when he's being too overconfident. They also support each other physically during battles, covering each other's backs and working as a seamless team.
Well, they might go on a mission together. Since Naruto is strong and Tenten is skilled with her weapons, they could face off against a group of bandits. They would support each other in battle, with Naruto using his Rasengan and Tenten throwing her various tools. It would be a great display of their friendship and teamwork.
Well, they could embark on a journey to explore an ancient ninja ruin. Naruto, with his curiosity, would be eager to discover new things, and Tenten, being knowledgeable about ninja history related to weapons and artifacts, could guide them. Along the way, they'd face various challenges and grow closer as friends.
Well, they could have an adventure in a new dimension. Naruto's ability to use chakra and Gohan's ki powers could be combined in unique ways. For example, they could use their combined energy to break through barriers that are otherwise impossible to cross. And they would surely make new friends and enemies in this new dimension.
They could go on an adventure to find a lost Wakandan artifact that has some sort of connection to Peter's powers. Maybe it was stolen by a group of thieves who don't understand its true value. Peter and Shuri would have to travel across different countries, using their unique skills. Peter's agility and spider - sense, and Shuri's intelligence and access to Wakandan technology.
They could have an adventure in an enchanted forest. Maybe they get lost and have to use Percy's skills with water to find a way out, like creating a stream that leads them to safety while Piper uses her charm - speaking to communicate with the forest animals for directions.
Friendship is a very common theme. They are always shown supporting each other through thick and thin. Another one is adventure. Since they are part of the Guardians of the Galaxy, most fanfictions involve them going on wild adventures in space.
They could have Pokémon battles against powerful trainers in different regions. Ash's battle experience combined with Cynthia's strategic skills would make them an unbeatable team.
They might go on a mission to protect a small village from bandits. Naruto's enthusiasm and Shikamaru's strategic mind would combine perfectly. Naruto could engage the bandits head - on while Shikamaru comes up with a plan to surround them and cut off their escape routes.
