Well, he could use his ninja skills to fight the Titans in a really cool way. Maybe he'd show the Survey Corps some new combat techniques. For example, his Shadow Clone Jutsu could be used to confuse the Titans while the soldiers attack from different directions.
Well, 'oc' usually stands for 'original character'. So it might mean that an original character in an Attack on Titan fanfiction experiences a fall. Maybe it's a physical fall like falling from a wall or a building in the context of the Attack on Titan world. Or it could be a metaphorical fall like a fall from grace or a fall into some sort of trouble within the story of the fanfiction.
Well, there's 'Titan - Shinobi Alliance'. This one is quite interesting as it imagines a scenario where the characters from Naruto and Attack on Titan form an alliance. The story has some great action scenes where ninjas and the Survey Corps work together. It also explores the cultural differences between the two groups, which makes for a very engaging read.
One possible scenario could be Naruto using his godlike powers to quickly assess and counter the Titans. His ability to sense danger and move at high speeds would make him a formidable force against the Titans. For example, he could use his shadow clones to distract the Titans while he goes for the kill with a Rasengan.
One example could be an oc who is overly confident in their abilities. They might think they can take on a Titan alone without proper training or backup. So they charge at a Titan and end up getting severely injured or killed, which is a 'fall' in terms of their physical state and over - confidence. Another example could be an oc who falls from the good graces of their comrades. Maybe they make a decision that goes against the group's ethics or code, like stealing supplies for their own benefit. As a result, they are shunned by the others, which is a social and moral 'fall' within the fanfiction.
One common theme is the clash of different powers. Naruto has his ninja powers like jutsu and chakra, while Attack on Titan has the ODM gear and Titan - shifting abilities. So, in many fanfics, there's a focus on how these powers interact when the characters from both worlds meet.
In a Juubi Naruto Attack on Titan fanfiction, Naruto could form an alliance with Eren. Naruto's ability to sense danger and his superhuman strength would be a great asset. He could teach Eren some of his ninja techniques, like how to better control his Titan form. Maybe Naruto could even find a way to use his Sage Mode to understand the Titans better.
One great 'Attack on Titan' fanfiction with a Titan reader is 'Titan's Perspective'. It delves into how a reader - turned - Titan experiences the world within the walls. It offers a unique view of the familiar 'Attack on Titan' universe, exploring the inner thoughts and struggles of a Titan, which is something not often explored in the original series.
Well, in such a fanfic, Harry Potter might find himself in the world of Attack on Titan. He could use his magic to fight the Titans in ways the Survey Corps has never seen before. Maybe he'd use spells like 'Wingardium Leviosa' to lift the Titans off the ground or 'Stupefy' to stun them. It would be really interesting to see how his magical abilities would interact with the technology and combat style of the Attack on Titan universe.
