Who could be the main character in an 'infinity armor crossover fanfiction'?

One idea could be to have the Infinity Armor cross over with a superhero universe. The wearer of the armor could team up with popular superheroes to fight a common enemy. Maybe they battle an interdimensional threat that only their combined powers can defeat.

Sasuke could also be a great main character in this fanfiction. Given his drive for power, he might be the one to seek out the dragon armor and use it to further his own goals. He could have an interesting journey of learning to control the power of the armor while also dealing with his inner demons.

Harry Potter himself could be the main character in this fanfiction. Imagine if he found the basilisk armor and used it to his advantage against Voldemort. It would add an extra layer of protection and power to his fight against the dark lord.

Wanda Maximoff could also be the main character. After losing Vision, she could be on a rampage. But then she realizes that she needs to control her powers and use them for the greater good. She could be a key player in trying to bring back the vanished ones and fighting any new threats that emerged after Infinity War.

It could be a new vampire character that is created specifically for this crossover. This vampire could be a hybrid of some sort, half - vampire and half - something else, and their unique nature draws the attention of both the vampire world and the characters from 'The Originals'.

Another option is that a new character introduced in the crossover could be the main character. For instance, in a Naruto - Fullmetal Alchemist crossover, an alchemist from the FMA world could stumble upon Naruto's sealed state and make it their mission to free him, while also getting involved in the politics and power struggles of the Naruto world.

It could also be a new character created specifically for the fanfiction. This character could be from the world of the crossover and have some special ability or knowledge that helps in the fight against the Heartless. Maybe they have a deep understanding of the magic or technology in their world that can be used to counter the Heartless threat.

A werewolf alpha could be the main character. He enters the 'familier of zero' world and has to navigate the complex magic and politics there. His werewolf instincts could either help or hinder him as he tries to understand this new world and find a way back home.

Well, Naruto might initially be confused by the Spartan armor. He could try to figure out its use and powers. Maybe he would think it was some kind of strange new jutsu - related equipment. He might then try to incorporate it into his fighting style, using his ninja skills along with the protection and potential weaponry of the Spartan armor.

It could be a new character who has been brought into the Fate Stay Night world with gamer - like abilities. This character might be from our world and has to use their gaming knowledge to survive and thrive in this new and dangerous environment.
