What are some interesting plot ideas for Ichigo x Naruto fanfiction?

One idea could be that Ichigo has to go on a special mission with a group of characters and during the journey, they all discover new powers within themselves. For example, Ichigo could learn a new form of his zanpakuto from an unexpected ally.

Maybe in a modern AU (alternate universe), Ichigo is a regular high school student and Lisa is a new transfer student. They meet in the library where Ichigo is studying for an exam and Lisa is looking for some rare books. Their initial encounter leads to a series of events that bring them closer together, like working on a school project.

One idea could be a story where Ichigo and Shirosaki are forced to team up against a new, powerful enemy that threatens both their existences. They have to learn to trust each other despite their differences.

One idea could be that Ichigo and Naruto are transported to a strange new dimension where they have to work together to find their way back home. They start by comparing their skills and learning from each other. For example, Naruto could teach Ichigo some of his shadow clone techniques, while Ichigo shows Naruto how to use his zanpakuto more effectively.

Maybe fem Ichigo has a different set of powers compared to Ichigo. In the fanfiction, they could train together to combine their powers in a unique way. For example, her powers might be more focused on defense while Ichigo's are on offense, and they learn to complement each other. This could lead to some interesting character development as they overcome their differences and work towards a common goal.

One idea could be that Ichigo, through some sort of interdimensional rift, ends up in the Avatar world of Legend of Korra. He could initially be seen as a threat due to his otherworldly powers. But as the story progresses, he teams up with Korra to fight a common enemy that is trying to take over both their worlds. His Soul Reaper powers could be used in unique ways, like using his Getsuga Tenshou to blast away dark spirits that are plaguing the Avatar world.

One idea could be that the OC has a special power that only activates when in close proximity to Ichigo. For example, the OC can sense Hollows from a great distance, which helps Ichigo in his battles against them.

One plot idea could be that Ichigo and Eragon meet in a dimension that is a cross - between their two worlds. They have to team up to fight a common enemy that is threatening both of their universes. Their different powers, Ichigo's Soul Reaper abilities and Eragon's dragon - riding and magic, would make for an interesting combination in battles.

One idea could be that Ichigo is somehow transported to the wizarding world. He might use his Soul Reaper powers in unique ways against dark wizards. For example, his Zangetsu could be seen as a sort of magical weapon that even wizards are in awe of.

Another plot could be that an ancient evil force targets Femichigo because she represents a new and unknown power in the Bleach universe. Ichigo vows to protect her at all costs. Along the way, they discover secrets about their connection that were hidden by the Soul Society, and they have to fight against not only the external threat but also the political intrigue within the Soul Society.
