Perhaps an anti - hero could be the main character. They find the Infinity Armor and initially use it for their own self - serving purposes. But as the story progresses, they start to see the bigger picture and become more heroic, using the armor to protect not just themselves but also the different worlds they encounter during the crossover.
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.
In the Infinity Wars comic, Loki's Infinity Armor is quite a game-changer. It's not only visually impressive but also grants him unique powers and strategic advantages. However, its appearance and capabilities can vary depending on the plot's needs.
In the Infinity Wars comic, Loki has a scheming relationship with the Infinity Stone and armor. Sometimes he teams up with others to get them, sometimes he works alone to control their power.
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.
One idea could be to have the heroes from Cartoon Network shows like Ben 10 and the Powerpuff Girls team up to fight against the forces similar to those in Infinity War. Ben could use his various alien forms to take on different challenges, while the Powerpuff Girls use their superpowers. They could also meet some of the Marvel characters and have some comical yet action - packed interactions.
Another theme is the alteration of reality. The Infinity Gauntlet can change reality, and in crossovers, this often leads to strange and unexpected situations. For instance, characters from one universe might find themselves in a completely different world due to the gauntlet's power, and they have to adapt. This theme adds a lot of intrigue and adventure to the fanfictions. Also, moral dilemmas are common. Characters have to decide whether to use the gauntlet's power for good or evil, and this internal struggle makes for some really interesting storylines.
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.
The Infinity Stones can be integrated by having them be the key to solving a major problem in a crossover. Say there's a threat that endangers multiple fictional universes. Characters from different worlds come together, and they discover that the combined power of the Infinity Stones is the only way to stop it. Each character might have a different idea on how to use the stones, leading to conflicts and alliances within the story. Also, a powerful villain from one universe could steal an Infinity Stone and use it to gain an upper hand over heroes from other universes, which would force the heroes to team up and find a way to take back the stone.
One idea could be a crossover between characters from different Disney Infinity franchises in a post - apocalyptic world. For example, Jack Sparrow from Pirates of the Caribbean and Elsa from Frozen teaming up to find a way to restore their shattered universes. Another idea is to have Buzz Lightyear and Stitch on an intergalactic adventure where they have to stop an evil force that is threatening multiple Disney worlds.
One interesting concept could be the different ways the Infinity Stones interact when characters from different universes come into contact with them. For example, if a character from a magical universe like Harry Potter's world encounters an Infinity Stone, how would their magic react to its power? Another concept is how the possession of an Infinity Stone might change a character's personality or goals in the crossover. A character who was once good might be corrupted by the power of the stone.
