In this crossover fanfic, it could be Doctor Strange. He has magic that can manipulate reality. He could potentially create barriers to keep the Titans at bay or even banish them to another dimension. His knowledge of the mystic arts would give him an edge over the other characters. While the Avengers have their physical powers and the 'Attack on Titan' characters have their own skills, Doctor Strange's magic is on a different level and could make him the most powerful in this unique scenario.
It's hard to say. Thor has his godly powers and his hammer Mjolnir which gives him great strength. But in the 'Attack on Titan' world, Eren's Titan form is also extremely powerful. However, if we consider all - around power, Iron Man with his advanced technology and ability to constantly upgrade his suit might be the most powerful. He could analyze the Titans' weaknesses and come up with strategies to take them down.
It's hard to say for sure, but Thor could be a very powerful character. His hammer gives him the ability to fly and strike with great force. Against the Titans, he could use his lightning powers to fry them. Also, his god - like strength and durability would make him a tough opponent for the Titans.
I think Iron Man and Armin would be an interesting pairing. Iron Man with his brilliant mind and high - tech gadgets could learn a lot from Armin's strategic thinking. And Armin could be amazed by Iron Man's technology and learn new ways to fight the Titans.
Thor would be a strong contender. His god - like strength and the power of Mjolnir, or Stormbreaker, could be very effective against the Titans. He could fly in and smash the Titans with his hammer, and his lightning powers could also do significant damage.
I think Naruto and Levi would be really interesting. Naruto's positive and determined attitude would contrast with Levi's more stoic and no - nonsense personality. They could learn a great deal from each other. Naruto could teach Levi about the power of friendship and believing in oneself, while Levi could show Naruto some of his amazing combat skills and discipline.
It's hard to say for sure. Superman has incredible strength, speed, and heat vision. But Thor has his godly powers and the mighty Mjolnir. Maybe in a crossover, it would depend on the situation. If it's a fight in space, Superman might have an edge, but if it involves magic, Thor could be more powerful.
In this crossover, the Avengers might use their high - tech weapons and superpowers to fight the Titans. For example, Iron Man could blast the Titans with his repulsor rays, and Thor could strike them with his lightning. The Titans, on the other hand, are huge and powerful. Their presence would pose a great threat to the Avengers and the world they are protecting. Maybe the Avengers would have to learn about the Titans' weaknesses quickly to stand a chance in this battle.
It would be epic! Imagine Eren Yeager with the powers of the Hulk. He could transform into a titan - Hulk hybrid, with the strength of both. The Avengers would be both confused and intrigued by the existence of Titans. Maybe Captain America would try to form an alliance with the Survey Corps to fight a common enemy that threatens both their worlds.
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.
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.
It has to be Naruto himself. His never - give - up attitude and his ability to make friends easily would make him a great addition to the world of Attack on Titan. He could inspire the characters in that world, like Eren, to keep fighting even in the face of despair. Also, his unique powers would be really cool to see against the Titans.
