Trish could be the most interesting. She has a complex past being a demon created by Mundus. Her alluring appearance and her powerful demon - like abilities make her stand out. In a fanfiction with Naruto, she could be the one who is more open to learning about Naruto's world and his powers. She might see in Naruto a chance to break free from her past and the expectations placed on her in the Devil May Cry world. Her relationship with Lady could also be further explored as they both interact with Naruto, and she could be the one to initiate the idea of a deeper connection with Naruto, whether it's a true'mate' relationship or just a strong friendship.
Well, one possible plot could be that in a strange crossover world, Naruto's chakra somehow connects with the demonic energy in the Devil May Cry universe. Lady and Trish, being the powerful demon hunters they are, initially see Naruto as a threat. But as they get to know him, they realize his noble intentions. Maybe Naruto helps them in a fight against a powerful new demon that is immune to their usual weapons and tactics. His unique abilities could be the key to victory, and during this adventure, a deep bond forms between them, not exactly a'mate' in the romantic sense at first, but more like comrades. As time passes, this bond could potentially develop into something more, with Naruto learning about their world and they learning about his ninja way.
I think Naruto and Dante would be an interesting pairing. Naruto's positive and determined attitude would contrast with Dante's more laid - back but still badass demeanor. They could learn a lot from each other in combat. Another interesting pairing could be Sasuke and Vergil. Both are brooding characters with a thirst for power, and their meeting could lead to some intense power struggles or even a begrudging mutual respect.
I think Vergil and Pennywise could also be an interesting combination. Vergil is very much about power and control. He would likely approach Pennywise with a more calculated mindset. Pennywise, on the other hand, would try to break Vergil's stoicism by getting into his head and exploiting his fears. It would be a battle of wills, with Vergil trying to cut through Pennywise's illusions and Pennywise trying to make Vergil doubt himself.
Ruby and Dante would be an interesting pairing. Ruby with her innocent and positive attitude could contrast with Dante's more laid - back and devil - may - care nature. They both are great leaders in their own ways and could learn a lot from each other in combat. Dante could show Ruby some new sword techniques and Ruby could show Dante the power of Aura and how it can be used in battle.
It's hard to say for sure, but Dante would be a strong contender. His experience in fighting demons and his vast array of weapons and abilities make him a formidable force. He has his devil trigger which significantly boosts his power, and his swordsmanship is top - notch. However, Naruto also has his own strengths. With the power of the Nine - Tails and his ability to use various powerful jutsu, he could also hold his own. But if we consider adaptability to different types of enemies, Dante might have an edge as he's used to facing all kinds of demons.
It's hard to say for sure, but Dante has a lot of experience and a wide array of powerful weapons and abilities. He has his Rebellion sword, Ebony and Ivory guns, and his devil trigger form which gives him enhanced strength, speed, and durability. However, Devilman also has his own unique powers, being part - human and part - devil. His ability to blend in with humans while having devil - like strength could give him an edge in certain situations.
The combination of different power systems is really interesting. In Naruto, we have chakra - based powers like Kushina's chakra chains, and in Devil May Cry, there are devil arms and demonic powers. When these two collide in fanfiction, it can lead to some really cool battle scenes and unique abilities for the characters.
It's likely Alucard. His vampiric powers are extremely potent. He can regenerate from almost any injury, has superhuman strength and speed, and can even manipulate shadows. In a crossover, he could potentially overpower many of the Devil May Cry characters, especially if he has the element of surprise.
Naruto's ability to create shadow clones would be very useful. He could send clones to scout out areas full of demons, or use them as distractions in battle. His rasengan could be a powerful close - range attack against demons. Also, his chakra control could potentially be used to enhance Devil May Cry weapons, like making a sword cut through tougher demon hides more easily.
The character of Trish is very alluring. In the Devil May Cry series, she has a unique personality and appearance. Fanfiction allows writers to explore different aspects of her character in new and exciting ways. The 'lemon' aspect, which often implies a more romantic or spicy take, can add an extra layer of interest for those who enjoy that type of storytelling.
