The comic could start with a chance encounter between the two groups, leading to confusion and mistrust. But as the story progresses, they might realize they need to work together to save the world from a greater threat that combines elements from both their universes.
Well, it's a tough call. Attack on Titan offers a gritty and emotional narrative. Avengers, on the other hand, has a more colorful and heroic universe. It really comes down to what kind of comic experience you're in the mood for.
Maybe some survivors from areas that were previously unmentioned. They could bring new skills and perspectives to the story.
The ending of AOT in the manga is quite controversial. Some fans loved it, while others were disappointed. It involves complex plot developments and character decisions.
I don't recommend or have any knowledge about such inappropriate or adult-oriented comics. It's not something worth discussing.
The crossover comic could have complex storylines. Maybe it'd explore how the different worlds and characters interact and how they handle the combined threats. It could lead to some mind-blowing action and character development.
A fanfiction could also be based on the Avengers trying to find a way to reverse the Titan transformation. They might see the Titans as victims of some sort of dark magic or science gone wrong. Bruce Banner, with his scientific knowledge, teams up with Armin from Attack on Titan. Armin provides all the information he has about the Titans while Banner tries to come up with a solution. Meanwhile, the rest of the Avengers are fending off any Titans that come their way.
Obviously, Eren as a baby is the central character. But we can also expect to see his family members like his father, Grisha. His mother, Carla, would also be an important presence as she plays a significant role in Eren's early life.
Lovi (Lovino Vargas from Hetalia) and Levi (from Attack on Titan) could be a likely pair. They both have that tough - exterior and are often seen as no - nonsense characters. Their interactions could be full of bickering and grudging respect. Another possible pair could be America (Alfred F. Jones from Hetalia) and Eren (from Attack on Titan). They are both quite headstrong and have a strong sense of justice, so they might team up to fight the Titans and try to bring about change in the world.
The Avengers' abilities would bring a whole new level of combat to the Attack on Titan world. For instance, Iron Man's flight and advanced weaponry would give him an edge in aerial attacks against Titans. Captain America's shield could be used to block Titan attacks and also as a throwing weapon. Thor's hammer would be a powerful melee weapon against the Titans. The characters from Attack on Titan, on the other hand, have their own skills like Eren's Titan - shifting ability. It would be interesting to see how they all work together.
A 'Attack on Titan Avengers fanfic' could be really exciting. It might involve the Avengers somehow getting transported to the world of Attack on Titan. Maybe Iron Man could use his technology to fight the Titans, like creating special weapons against them. Captain America could lead the Survey Corps in a battle strategy. And Thor with his hammer could be a powerful force against the Titans as well.
