One idea could be exploring Dante's early days as a devil hunter, like his first encounter with a really powerful demon. It would show his growth and how he developed his skills.
Another interesting concept is to create a story where Nero teams up with a new character. This new character could have a unique power that Nero has to learn to work with, and they go on a mission to save a city from a new type of demon threat.
One idea could be to create an OC who is a descendant of a powerful demon hunter family. This OC could have a unique weapon that combines the abilities of different Devil May Cry weapons, like a sword that can also fire bullets. Another idea is an OC with a special power to control time briefly during battles, adding a new dynamic to the fight scenes. You could also have an OC who is a half - demon, half - angel, struggling with their dual nature and how it affects their place in the Devil May Cry universe.
A crossover with the Castlevania universe would also be cool. Dante could find himself in Dracula's castle, facing off against classic Castlevania monsters while also dealing with his own demonic foes. It would be interesting to see how he interacts with the Belmonts.
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.
One idea could be that Pennywise from 'it' somehow enters the world of 'Devil May Cry'. Dante could mistake Pennywise for a particularly grotesque demon and engage in a battle. Pennywise, with his shape - shifting abilities, would constantly change forms to try and deceive Dante. Another plot could involve the characters from 'Devil May Cry' being lured into Derry by Pennywise's illusions. They then have to fight their way out while also dealing with the psychological warfare that Pennywise is known for.
One idea could be a crossover with the Bayonetta series. Dante and Bayonetta could team up to fight a common, powerful demon. Their different fighting styles would make for some epic battles and interesting interactions. For example, Dante's flashy swordplay combined with Bayonetta's acrobatic and magical combat.
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.
One plot idea could be a crossover where the characters from RWBY have to team up with Dante from Devil May Cry to fight a powerful demon that has somehow made its way into the RWBY universe. This would bring in Dante's combat skills and his devilish powers to the mix.
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 Naruto somehow ends up in the Devil May Cry world. He might mistake some of the demons there as similar to the tailed beasts he knows. For example, he could try to 'befriend' a demon in the DMC world thinking it's like how he dealt with Kurama. Another idea is Dante teaching Naruto some swordsmanship. Dante's flashy and powerful combat style could blend well with Naruto's own energetic fighting moves.
Well, one interesting concept could be the fusion of the dark and edgy style of Devil May Cry with the colorful and magical world of My Little Pony. Maybe it involves characters from Devil May Cry having to adapt to the more positive and harmonious environment of Equestria. For example, Dante might find himself in a situation where he has to use his combat skills in a non - violent way to solve problems in Ponyville.
