A good crossover character could be Naruto. He and Ichigo share some similarities in their determination and their growth as characters. They could team up in the new dimension, with Naruto's ninja skills and Ichigo's sword - fighting abilities making for an interesting combination against the new threats they face.
Another plot could be that Ichigo is transported to a dimension that is a post - apocalyptic world. Here, his skills as a fighter would be put to the test. He might find remnants of a once - great civilization that had technology far different from his own, and he has to use both his swordsmanship and his wits to navigate this dangerous new world.
One common theme is self - discovery. As Ichigo travels through different dimensions, he often has to re - evaluate who he is and what his purpose is. Another theme is the exploration of different power systems. Each dimension may have its own unique set of powers and rules.
Ichigo often develops greater adaptability. He has to quickly adjust to the new environment, rules, and powers in the other dimension. This makes him more flexible in his thinking and combat strategies. For example, if the dimension has a different type of energy, he learns to incorporate it into his attacks.
A frequently used plot device is the change in relationships. When Ichigo is sent to another dimension, his relationships with his friends back home are put on hold, and he forms new bonds in the new place. He might meet a mentor - like figure in this dimension who teaches him new combat techniques or ways to control his powers better. Another common one is the culture shock. The new dimension could have a completely different society, values, and ways of living, which Ichigo has to navigate. This can lead to some interesting character development as he learns and grows from these experiences.
One interesting character to crossover with Ichigo is Light Yagami from Death Note. The clash between Ichigo, who is a protector, and Light, who is a morally ambiguous character with the power to kill, would be very engaging. Saitama from One - Punch Man could also be a great choice. Saitama's overpowered nature and Ichigo's journey to become stronger would make for an interesting story. And what about Alucard from Hellsing? His vampire powers and Ichigo's powers related to the afterlife would create a really dark and exciting crossover.
One great 'Bamf Ichigo Dimension Travel' fanfiction is 'Ichigo's Multiverse Adventures'. It has an exciting plot where Ichigo travels to various dimensions and meets different versions of his friends and foes. The character development is really well - done, making it a must - read for fans.
Aizen Sousuke would be an interesting crossover character. Since he's so powerful and manipulative in the Bleach universe, seeing him in a different setting with Ichigo could create some really complex and intense storylines. They could be forced to work together against an even greater evil in a crossover universe.
Ichigo could meet Frodo Baggins. Frodo, being from a very different kind of world, would find Ichigo's situation strange. But they could bond over their shared sense of being out of place in some ways. Frodo could teach Ichigo about the importance of perseverance in the face of great odds, and Ichigo could protect Frodo from any potential threats in this crossover world with his swordsmanship.
One idea could be that Ichigo and Naruto are brought together by some sort of interdimensional rift. They initially don't understand each other's powers but soon realize they share a common goal of protecting their friends and worlds. They could team up to fight a powerful enemy that threatens both their universes.
