What are some interesting ideas for a Bleach Attack on Titan crossover fanfiction?

In an 'Attack on Titan' and 'Titanfall' crossover fanfiction, there could be a plot where the world of 'Titanfall' is somehow connected to the world of 'Attack on Titan' through a rift in space - time. The Pilots could be sent to the 'Attack on Titan' world to help in the fight against the Titans. They could introduce their Titan - mech technology to the people there. The story could also focus on the cultural shock that both sides experience. The Pilots would be shocked by the primitive living conditions in 'Attack on Titan' while the 'Attack on Titan' characters would be amazed by the high - tech machinery of the Pilots.

One idea could be that Mel, a character from another universe perhaps, has some unique ability that can help the Survey Corps in 'Attack on Titan' deal with the Titans. For example, if Mel can manipulate time, she could freeze the Titans in place, giving the soldiers a chance to attack without risk. Another idea is that Mel accidentally ends up in the world of 'Attack on Titan' and has to learn the ways of survival there. She could form an unlikely friendship with Eren or Mikasa and together they discover new ways to fight the Titans.

The combination of different power systems. In Bleach, you have spiritual powers like zanpakuto and kido, while in Attack on Titan, there are the unique abilities related to the Titans. Seeing how these interact in a crossover is really cool.

Perhaps the friendly titan is a protector of a certain area outside the walls that the humans have not explored much. The story could be about the Survey Corps making an alliance with this titan. The titan guards the area from other dangerous titans, and in return, the humans help the titan when it gets injured. This could lead to a whole new understanding of the titan world and how they can co - exist with the friendly ones.

Ichigo and Eren would be a very interesting pair. Ichigo has his powerful Soul Reaper and Hollow powers, and Eren has the power of the Titans. They could learn from each other, like Ichigo teaching Eren about controlling his inner power better, and Eren showing Ichigo the determination of the people in the Attack on Titan world.

A great 'bleach crossover fanfiction' idea is to cross it with One Piece. The Straw Hat crew could end up in the Soul Society. Luffy's carefree attitude would contrast with the more solemn Shinigami. Also, a Bleach and Fullmetal Alchemist crossover where the alchemic principles are applied in the Bleach universe would be really interesting.

Sure. One popular 'bleach attack on titan crossover fanfic' is 'Soul Reapers in the Walls'. It combines the unique powers of the Soul Reapers from Bleach with the post - apocalyptic world of Attack on Titan in an interesting way.

One idea could be that your OC is a new recruit in the military and gradually gains the attention and affection of various popular characters like Eren, Levi, and Armin. They are all drawn to the OC's unique skills and personality.

A male OC in an Attack on Titan fanfiction could be a double agent. He pretends to be on the side of the Titans while actually working for the Survey Corps. He could have been captured by the Titans as a child and raised among them, but his human instincts and loyalty to his own kind make him turn against the Titans. Another interesting idea is a male OC who is a healer. In a world full of Titan attacks, most of the focus is on combat, but a healer OC could bring a new dimension to the story. He could develop new medical techniques to treat the wounded soldiers, and his struggle to keep people alive in the face of such danger could be a great plot point. And also, a male OC who is a historian, trying to uncover the secrets of the past about the Titans and the origin of the walls.

One idea could be exploring an alternate timeline where the main characters have different Titan powers. For example, Eren could have the Colossal Titan's power from the start. Another could be a story centered around a new character who joins the Survey Corps and has a unique ability to communicate with Titans on a deeper level. Maybe they try to find a peaceful coexistence with the Titans instead of just fighting them all the time.
