If Spawn were to interact with the main characters, he would bring a whole new level of seriousness. He has a dark past and a lot of baggage. When it comes to Issei's goal of becoming a harem king, Spawn might find it absurd but also interesting in a way. He could offer his own perspective on power and how to use it responsibly, which would be a contrast to the more carefree attitude of some of the Highschool DxD characters. And with the other characters like Akeno and Koneko, he'd be sizing them up, trying to figure out if they're threats or allies.
Naruto would probably be very friendly and curious. He'd be excited to meet all the different types of beings in the Highschool DxD world. He might start by trying to make friends with Issei, sharing his stories about his own battles and adventures in his world.
Well, first there's Issei. He's the protagonist, a former human turned devil. Rias Gremory is really important. She's a powerful devil and kind of Issei's mentor in the devil world. Akeno is also a main character. She has a unique personality and is close to Rias. Kiba Yuuto, he's a skilled swordsman among the devils. And Xenovia is interesting too. She starts as an exorcist but then her path crosses with Issei and the others, which changes things for her.
In 'Highschool DxD' fanfiction about Rias, her character often retains her strong - willed and noble nature. She is a powerful devil, and in fanfictions, her leadership skills and loyalty to her friends are usually emphasized.
Akeno Himejima is also a key character. She is one of Rias' peerage members and has a complex personality. Koneko Toujou, a cat - like devil, is part of the group as well. She has a strong fighting ability and an interesting backstory.
The female characters from Highschool DxD, like Rias, would be intrigued by the unique personalities of the Naruto characters. Rias might see potential in some of them to join her peerage. And the Naruto girls, like Sakura, would be a bit shocked at first by the more revealing outfits and flirty nature of some of the Highschool DxD characters. But over time, they would bond over things like protecting their friends and the school. The Naruto boys would respect the power of the Highschool DxD devils and might even try to incorporate some of their fighting strategies into their own ninja combat styles.
Goku's powers are on a completely different level compared to most characters in Highschool DxD. His Saiyan abilities like Super Saiyan transformations give him incredible strength, speed, and energy projection. In contrast, the characters in Highschool DxD mainly rely on magic and their devil or angelic powers which, while powerful, are not on the same scale as Goku's in terms of raw power. For example, Goku could easily defeat most low - level devils with a single punch in his base form.
In Highschool DxD fanfiction, characters might watch various things. For example, they could watch magical battles between different factions. Since the world of Highschool DxD is filled with devils, angels, and other supernatural beings, these battles can be quite spectacular. They may also watch training sessions of powerful fighters, learning new techniques and strategies. Another possibility is that they watch cultural events specific to their different species, like a devil's ball or an angel's ceremony, which can help them understand the traditions and values of each group.
The main character is Issei Hyoudou. He's a high school student who gets turned into a devil. Then there's Rias Gremory, a powerful devil and the president of the Occult Research Club. Akeno Himejima is also important. She's a devil and one of Rias's servants.
Great Red is also a very popular dragon in Highschool DxD fanfiction. Given his mysterious and powerful nature, many fanfictions explore his potential influence on the main characters' lives and the overall plot of the story. His abilities are often expanded upon in these fan - created works.
