One common theme is the exploration of new powers. When Toshiro Hitsugaya is in a different universe, he has to either adapt his existing ice - based powers or gain new ones. For example, in a crossover with a superhero universe, he might learn how to fly or have enhanced strength.
I really like 'Hitsugaya's New Adventure'. In this fanfic, he crosses over into a modern - day world, which leads to some really interesting and humorous situations as he tries to adapt to things like technology and modern social norms. It also has some great character interactions.
One great idea for a Toshiro Hitsugaya and Sakura Haruno fanfiction could be a story where they meet in a dimension -rift situation. Toshiro, from the Bleach universe, and Sakura from Naruto, both have their unique powers. Toshiro's ice - based abilities and Sakura's medical ninjutsu and strength could create an interesting dynamic. They might initially be at odds, not understanding each other's worlds, but as they face common enemies or challenges in this new, strange dimension, they start to work together and learn from each other.
There's also a crossover where Toshiro Hitsugaya meets characters from 'Fullmetal Alchemist'. In this fanfic, the clash between his ice - based powers and the alchemy - based world creates really interesting scenarios. The author does a great job of exploring how he would interact with the Elric brothers and other characters. It's full of action and some really cool power - up moments for Toshiro.
A good Toshiro Hitsugaya crossover fanfic should first have a believable crossover concept. For example, if he crosses into a different anime world, the rules of that world need to be well - established and his integration into it should make sense. His character traits should also be maintained, like his cool - headedness and strong sense of justice.
There's a fanfiction called 'Toshiro's Journey of Redemption'. It takes Toshiro on an emotional journey where he has to face his past mistakes. The author does a wonderful job of portraying his internal struggles.
Another plot idea is that a powerful villain uses a jutsu to merge the worlds of 'Bleach' and 'Naruto'. Hitsugaya and Naruto meet and at first have trouble understanding each other's abilities and cultures. But as they face challenges together, they learn from one another. For example, Hitsugaya could teach Naruto some sword - fighting skills, while Naruto could show Hitsugaya how to use chakra more effectively.
I'm not entirely sure if there is a large quantity of it, but considering the popularity of both Harry Potter and Bleach, it's very possible. Some fans enjoy creating scenarios where characters from different stories interact. For example, they might write about how Toshiro Hitsugaya would fare in the wizarding world of Harry Potter, or how Harry Potter characters would react to Toshiro's ice - based powers. However, you would need to search on specific fanfiction websites to find such works.
Well, self - discovery is a significant theme. As he's still young, he has a lot to learn about himself and his place in the world. Fanfictions might take him on a journey where he uncovers parts of his past or future potential. Another common aspect is his role as a leader. He has to lead his division, and fanfictions could show the challenges and triumphs he experiences in that leadership role, all while dealing with the various threats that come his way in the Bleach universe.
Definitely Naruto and Hitsugaya. Naruto's boisterous and determined personality would contrast greatly with Hitsugaya's more stoic and cold - natured self. Their interactions could start with misunderstandings due to their different worlds and ways of doing things. But as they get to know each other, they could form a strong bond based on mutual respect for their powers and goals.
