One more plot twist could be that the Devil May Cry world is actually a parallel dimension created by an ancient Asgardian magic long ago. When the Avengers accidentally open a portal to this world, they find that the demons there are not just mindless monsters but are part of a complex society. And some of the Devil May Cry characters are actually descendants of Asgardians who were trapped in this dimension. This would lead to a complex web of relationships and power struggles as the two groups try to figure out their connection.
Perhaps a plot twist where one of the main Avengers, like Captain America, is actually a reincarnation of a hero from the Devil May Cry world. This would bring in a whole new backstory for him. He would start to show abilities related to Devil May Cry, like being able to sense demons or having enhanced sword - fighting skills. It would also create a conflict within him as he tries to balance his newfound identity with his role as an Avenger.
One idea could be that Dante from Devil May Cry is somehow transported to the Marvel universe. He teams up with the Avengers, like Iron Man. Dante's unique combat style and devil - slaying abilities would be a great addition to the team. For example, he could use his Rebellion sword against powerful foes that the Avengers are having trouble with, such as Loki if he were to return in a more powerful form.
One way to blend Devil May Cry and Avengers fanfiction could be through a crossover of characters. For example, Dante from Devil May Cry could team up with Iron Man. Dante's sword - fighting skills and superhuman abilities would make for an interesting combination with Iron Man's high - tech gadgets. They could fight a common enemy that has elements of both the Devil May Cry and Avengers universes, like a demon - like alien.
One idea could be a story where Dante discovers a hidden demonic realm within the human world that has been influencing events without his knowledge. He has to team up with a new, inexperienced hunter to navigate this strange place.
Maybe Bucky shocks them by suddenly showing a new power or ability that no one expected. He could have been experimented on further during his time in captivity and this new power throws the Avengers off - guard as they now have to reevaluate how to fight alongside him or against him if he were to turn.
In some Batman vs Avengers fanfiction, a great plot twist is when Batman manages to hack into the Avengers' communication system and makes them fight among themselves. He then uses the chaos to his advantage. Another cool twist is that there's a greater threat looming, and Batman and the Avengers have to put aside their differences and work together. But as they do, they discover that one of the Avengers has been replaced by a shape - shifter, and Batman has to figure out who it is before it's too late. There could also be a plot twist where Batman uses a device that actually amplifies his own strength and skills to the point where he can match the Avengers' superpowers, at least temporarily.
In some fanfictions, a plot twist could be that Ghost Rider is actually a key to unlocking an ancient power that the Avengers need to defeat a new, extremely powerful enemy. This changes the whole dynamic as the Avengers have to protect and work with Ghost Rider in a different way.
In some fanfics, a great plot twist is when Ghost Rider turns out to be the key to defeating an enemy that the Avengers thought was unbeatable. His hellish powers were the one thing that could counter the enemy's invulnerability.
One interesting plot idea is Izuku inheriting some of Dante's powers. For example, he could gain the ability to use Devil Arms and his combat skills could be enhanced in a unique way. Another could be Izuku getting involved in the demon - hunting world of Devil May Cry while still trying to be a hero in his own world. It would be a cool mix of the two universes.
One idea could be an OC who is a descendant of a powerful demon slayer family. They come to the world of Devil May Cry with unique weapons and skills, and have to team up with Dante and the gang to face a new, super - powerful demon threat. Their family's secrets and ancient techniques add new twists to the story.
One idea could be that the characters from RWBY end up in the Devil May Cry world and have to team up with Dante to fight off a new type of demon that is attracted to the unique Aura energy of the RWBY characters. Another could be a crossover where Nero and Ruby exchange their weapons for a short time and learn from each other's fighting styles. Maybe Yang could also have a friendly sparring match with Vergil to compare their strength and swordsmanship skills.
