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.
Well, the exploration of new storylines is a big draw. It's not just about the characters fighting side by side. Fanfic writers often come up with complex plots that involve things like the origin of the Titans being related to the Hollows in Bleach, or the Soul Society having a role in the history of the walls in Attack on Titan. This opens up a whole new realm of possibilities that wouldn't exist in either of the original series alone.
The character interactions can be really fascinating. Imagine Mikasa Ackerman teaming up with a powerful Pokemon like Charizard. She could ride on its back and use her combat skills along with Charizard's fire - breathing abilities to take on Titans. Also, the idea of the Pokemon having to adapt to the world of Attack on Titan, where there are different rules and a lot more danger, is an aspect that can be explored in many interesting ways.
The character interactions are great too. Imagine the stoic and highly - trained Gundam pilots meeting the passionate and often reckless Survey Corps members. Their different personalities and values can lead to some really engaging dialogues and character development. Some fanfics explore how they learn from each other, like the Survey Corps learning about more strategic combat from the Gundam pilots, and the Gundam pilots learning about the importance of hope and determination from the characters in Attack on Titan.
One idea could be that the Soul Reapers have to enter the world of Attack on Titan to stop Hollows that are being created by the Titans' negative energy. Another could be that Eren Jaeger somehow gains Soul Reaper powers and uses them to fight both Titans and Hollows. Maybe Ichigo could end up in the walls and teach the Survey Corps his sword - fighting techniques to better combat the Titans.
The combination of powers. For example, seeing Zoro try to fight against a Hollow with his swords in a One Piece - Bleach crossover is fascinating. His swordsmanship could be contrasted with the way Soul Reapers use their zanpakutos.
The most interesting aspect is the power mash - up. Naruto's ninjutsu and Ichigo's zanpakuto powers combined can create some really epic battle scenes. For example, Naruto could use his Rasengan while Ichigo uses his Getsuga Tensho simultaneously in a fight against a common enemy.
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.
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.
A cool plot twist could be a ghoul - Titan hybrid. Imagine a Titan with the regenerative abilities of a ghoul. This would pose a whole new level of threat to the characters from both universes. Also, the idea of the ghouls' coffee being a valuable resource in the Attack on Titan world could be an interesting twist. Since coffee is so important to ghouls, it could have some unforeseen effects on the Titans or the people in that world.
One interesting interaction could be between Optimus Prime and Erwin Smith. Optimus, with his strong sense of leadership and justice, would likely respect Erwin's strategic mind and his willingness to sacrifice for the greater good. They could exchange ideas on leading their respective groups in the face of great danger. Another would be between Bumblebee and Eren. Bumblebee's friendly and curious nature could contrast with Eren's often - brooding and determined self. Eren could be amazed by Bumblebee's technology and abilities, while Bumblebee could be intrigued by Eren's Titan - shifting power.
Well, one interesting aspect could be the unique crossovers. Combining the intense world of Attack on Titan with the cuteness of kittens creates a really fun contrast. It might also introduce new character dynamics, like how the kittens interact with the titans or the Survey Corps members.
