Maybe Dante Vale is on a mission to find a particular magical item that has been lost in the wizarding world. Harry and his friends could help him in his search. Along the way, they discover that the item has a connection to both their worlds and its power could either save or endanger both realms.
Hermione would be a great candidate. Her thirst for knowledge and eagerness to learn about different forms of magic would make her very interested in Dante Vale and his skills. She would probably bombard him with questions and they could have long discussions about magic.
Danny is extremely powerful as a half - ghost. His powers are based on ectoplasm and he has a wide range of abilities that make him a formidable opponent. However, Dante has been trained to fight demons all his life. He has strength, speed, and agility, as well as a vast knowledge of different types of demons and how to defeat them. If they were to face off in a straight - up fight without any environmental factors, it would be a close call. Danny's powers are more supernatural in nature, while Dante's are more combat - based. So, it's really hard to say who would be stronger.
One idea could be that Danny and Dante team up to fight a powerful ghost - demon hybrid that is causing chaos in both their worlds. They could use their unique powers to complement each other in battle.
I don't think it's a valid statement in the traditional sense. Harry Potter has its own unique world -building, characters, and plotlines that are distinct from Dante's works. Dante's writing is more of a deep exploration of the afterlife and moral concepts. Harry Potter focuses on a magical school, magic in a more contemporary - feeling world, and battles against dark wizards. There is no real indication that J.K. Rowling wrote Harry Potter as fanfiction of Dante.
Maybe they just saw some very superficial similarities. For example, both stories have elements of a journey. In Dante's 'The Divine Comedy', he goes on a journey through the afterlife, and in Harry Potter, Harry and his friends go on various adventures through Hogwarts and other magical places. But that's about as far as it goes really.
Well, it could involve Harry having some of Dante's devil - slaying abilities. Maybe he uses them to fight the dark forces in the wizarding world that Voldemort represents in a more unique way than just magic. For example, he could have enhanced speed and strength like Dante to take on Death Eaters.
He'd probably be more confident. Dante is a very confident character, and if Harry is his son, he might inherit that trait. He'd be less likely to be intimidated by bullies like Draco or even the Death Eaters.
There's also a possibility that it's Trish. She could be calling to warn Dante about a new threat that she has discovered. Dante would trust her information and start to make preparations to face this new danger.
Sure, it's very likely that such a fanfiction exists. Given the popularity of both Naruto and Dante, fans are always eager to create unique crossovers. In a 'naruto is dante fanfiction', one could imagine Naruto having some of Dante's abilities or characteristics, or perhaps they are in the same world facing common enemies. But keep in mind that the availability and popularity of such a fanfiction would depend on the fan community's interest in this particular crossover.
