Ichigo's power might be enhanced or changed. For example, if they travel to a time when the Hollow and Soul Reaper powers were more intertwined, he could gain a new form or ability. His Zanpakuto might also have different properties. Unohana's healing powers could be affected too. She might find that in some past or future time, her healing abilities are either more potent or restricted, depending on the state of the Soul Society at that time.
Perhaps the time travel is not what it seems. It could be a trap set by an unknown enemy. When Ichigo and Unohana think they are traveling through time to fix something, they are actually being led into a situation where they will be separated and used against each other. This would create a lot of drama and conflict in the fanfiction.
Well, 'A Time - Twisted Love' is a popular ichigo x rukia time travel fanfiction. In this story, a mysterious force sends them on a time - traveling adventure. As they travel, they discover things about each other that they never knew before. Also, 'Time Warp of Souls' is worth reading. It delves deep into the consequences of time travel on their souls and how they struggle to keep their connection alive throughout the time - jumping chaos.
To write an Ichigo and Unohana fanfic, start by imagining a unique situation for them. Maybe it's a world where they are both outcasts for some reason. Then, build their relationship gradually. Show how Ichigo might initially be intimidated by Unohana but then grows to trust her. You can also add some emotional depth by exploring their personal traumas. For instance, Ichigo's struggle with his Hollow side and Unohana's past as a more violent self. Use vivid descriptions of their surroundings and actions to make the story come alive.
I'm not sure if there is a specific fanfiction about Ichigo and Unohana being pregnant. There are so many fanfictions out there that it's difficult to say for certain. You could try searching on popular fanfiction websites to see if such a story exists.
Ichigo is often headstrong and driven by his sense of justice. Unohana, on the other hand, is more reserved and has a deep well of knowledge. Their personalities would likely create a dynamic where Ichigo might initially be a bit frustrated by Unohana's calm approach, but gradually learn to appreciate it as he realizes the wisdom behind it.
I'm not sure if there is such a specific fanfiction. Fanfiction can cover a wide variety of scenarios, but this particular one might be a bit rare or not in line with the general tone of the original work. You could try searching on some major fanfiction websites to see if it exists.
One possible plot could be that Ichigo gets sent back in time accidentally due to some of Kisuke's experiments gone wrong. He then has to figure out how to get back to his own time while also dealing with the past versions of his friends and enemies. Kisuke, of course, feels responsible and tries to help him.
One common theme is self - discovery. When they travel through time, both Aizen and Ichigo often learn more about themselves. For example, they might see how their past actions have led to certain situations. Another theme is the alteration of fate. They may try to change things in the past, which has consequences for the present and future of the Bleach world.
