One possible adventure is that they get caught up in a time - traveling incident. They end up in different eras, like Naruto in the Saiyan - dominated era and Gohan in the ninja - filled Hidden Leaf Village.

Naruto would lead the way with his Rasengan, Inojin would use his art techniques to create distractions, and Himawari could use her Byakugan to spot the enemy's weak points.
They could have an adventure exploring the Forbidden Forest. Dudley, being curious about Harry's world, could tag along with Harry. They might encounter magical creatures like centaurs or unicorns.

This adventure would strengthen their friendship as they rely on each other in the forest.
They might have adventures exploring different planets. Peter's charm and Rocket's combat skills would make them a great team.
