I'm sorry, but I don't have specific 'bleach ichigo and soi fon lemon fanfiction' to recommend directly. You could try searching on fanfiction websites like FanFiction.net or Archive of Our Own. They have a large collection of Bleach - related fanfictions, and you might be able to find the ones featuring Ichigo and Soi Fon there.
In lemon fanfiction, Ichigo and Soi Fon's relationship can be quite interesting. Often, it might explore their characters in new ways that the original story doesn't fully cover. For example, it could show a more emotional side of Soi Fon towards Ichigo, perhaps blurring the lines between her usual stoic self and a more vulnerable state.
Well, a common theme could be their mutual growth. Ichigo is constantly evolving in his powers and understanding of the spirit world, and Soi Fon has her own journey of self - discovery. They could influence each other's growth in a non - romantic or non - inappropriate way. For example, Soi Fon could teach Ichigo some of the more disciplined aspects of the Soul Reaper way, while Ichigo could show Soi Fon the value of thinking outside the box in combat situations. Also, a theme could be their struggle to protect their comrades and the Soul Society, and how they support each other in that regard.
Common themes in this type of fanfiction also include trust - building. Given their different backgrounds, they would need to build trust in order to have a relationship. There could also be themes related to redemption, especially if there have been past conflicts between them. Additionally, themes of acceptance - both of themselves and of each other - are likely to be present in these fanfictions.
I'm not entirely sure what 'harry is fon fanfiction' specifically means. It could be a very unique or misspelled title. Maybe it's about a character named Harry in a fan - created story that has something to do with 'fon', but without more context it's hard to say for sure.
One interesting crossover idea could be a battle tournament where characters from both Bleach and Fairy Tail participate. For example, Ichigo from Bleach could face off against Natsu from Fairy Tail. Their different fighting styles, with Ichigo's zanpakuto and Natsu's dragon slayer magic, would make for an exciting showdown. Another idea could be a team - up scenario. Maybe some of the Soul Reapers and Fairy Tail mages have to work together to defeat a common, powerful enemy. This would allow for interactions between characters who have different powers and personalities, like Rukia and Lucy. They could learn from each other's magic systems and grow as characters during the adventure.
A good way to create compelling character interactions is to play on the differences in their powers. Take Lucy from Fairy Tail and Uryu from Bleach. Lucy uses her celestial spirits, while Uryu has his Quincy powers. If they were to meet, they could initially be curious about each other's powers. Lucy might be amazed at the precision and control Uryu has over his arrows, while Uryu could be intrigued by the concept of celestial spirits. This curiosity could lead to them trying to learn from each other, or even having a friendly competition to see whose power is more effective in a certain situation. Through these interactions, their characters can grow and a deeper relationship can be formed.
One idea could be a tournament where characters from Bleach and Fairy Tail compete. For example, Ichigo from Bleach could face off against Natsu from Fairy Tail in a battle of strength and sword skills versus fire - based magic. Another plot could involve a common enemy that forces the two groups to team up. They start off distrusting each other but gradually learn to work together. Maybe a powerful dark force is threatening both their worlds and they have to combine their powers to defeat it.
It's hard to say for sure. Ichigo in his final form in Bleach has extremely high power levels. He can cut through almost anything with his sword and has great speed and strength. However, in Fairy Tail, Acnologia is a very powerful dragon slayer. His dragon form gives him incredible power and he has a lot of combat experience. So it could be either of them depending on how the fight is set up.
