Well, it could be about the Survey Corps teaming up with the Avengers. Maybe Eren's titan form could be as strong as the Hulk in a battle against a common enemy like Thanos. The Scouts' ODM gear would be an interesting contrast to the high - tech gadgets of the Marvel heroes.
Well, it could be amazing. Imagine the Survey Corps teaming up with the Avengers. Eren could use his Titan powers alongside Thor's godly strength. Maybe they'd be fighting a common enemy like Thanos who has somehow made his way to the Attack on Titan world. The different powers and personalities would create really interesting dynamics.
I think Eren and Spider - Man could make a great pairing. Eren has his determination and the power of the Titans, and Spider - Man has his agility and quick thinking. They could learn a lot from each other in terms of fighting skills and moral values.
One common theme is power struggle. Both 'Attack on Titan' and Marvel have characters with great powers. In the fanfics, it's often about how the powers from 'Attack on Titan' like the Titan - shifting abilities compare and interact with the superpowers in Marvel.
The cultural clash. The Marvel heroes come from a world with a different set of values compared to the more survival - based world of Attack on Titan. Seeing how they interact and try to understand each other's motives would be really engaging. For example, Steve Rogers might try to instill his sense of justice and freedom in the characters of Attack on Titan, while they might show him the harsh realities of their world.
A really cool plot could be that some of the Attack on Titan characters gain superpowers from the Marvel universe. For example, Mikasa could get some sort of enhanced combat abilities like Black Widow's training but on steroids. And the Survey Corps could learn new technology from Tony Stark to better fight the Titans. Also, Loki could play a devious role in the crossover, causing chaos between the two worlds by manipulating both sides.
One common theme is the clash of different power systems. For example, when crossing over with a magic - based series, the contrast between the Titans' brute force and magic is explored.
The story could begin with Optimus Prime leading the Autobots to a new dimension in search of a powerful energy source. This dimension turns out to be the world of Attack on Titan. The Survey Corps mistakes the Autobots for new threats at first. However, Armin, being the intelligent one, quickly realizes that they might be able to help in the fight against the Titans. Meanwhile, Megatron and some Decepticons also arrive. They see the Titans as potential weapons or servants. The Autobots then form an alliance with the Survey Corps. Optimus Prime is impressed by the courage of the humans, especially Mikasa Ackerman. As they battle the Titans together, the Autobots teach the humans about advanced technology, and the humans show the Autobots the importance of unity and tenacity in the face of a seemingly unbeatable enemy.
In a 'halo crossover attack on titan fanfic', there could be many interesting scenarios. For example, Master Chief could team up with Eren Yeager. Master Chief with his superhuman abilities and advanced weaponry could offer new strategies to fight the Titans. The fanfic might also explore how the different cultures and power systems in both Halo and Attack on Titan clash or merge. It could be a story full of action, adventure, and the exploration of two very different fictional worlds coming together.
It could be a very interesting creative crossover. MLP (My Little Pony) has a very different aesthetic and tone compared to Attack on Titan. In a fanfic, it might involve ponies in the world of Attack on Titan, perhaps with their own magical abilities helping or hindering the fight against the Titans. For example, Twilight Sparkle could use her magic to analyze the Titans' weaknesses in a way the Survey Corps couldn't on their own.
