The female characters in High School DxD, like Rias, might be charmed by Ash's kind heart and his relationship with his Pokemon. They could offer Ash protection in their world in exchange for seeing more of his Pokemon. Ash would be grateful and in return, he could offer to help them with any problems they have using his Pokemon's abilities. This interaction could lead to new adventures and friendships in the fanfiction.
Issei would likely be excited to meet Ash. He might see Ash as a unique and powerful individual. Ash could introduce Issei to his Pokemon, like how they train and battle. Issei could then show Ash some of his techniques in combat. They could also end up teaming up against a common enemy, with Ash using his Pokemon's powers and Issei using his Boosted Gear. This would create a really interesting dynamic between the two.
Ash would probably be curious about the devils and angels in High School DxD. He might try to befriend them with his friendly and innocent nature. The devils and angels, on the other hand, would be intrigued by Ash's Pokemon.
The Power Rangers, being used to a more action - oriented and team - based dynamic, would likely bring their sense of discipline and cooperation to the interactions. They might be initially confused by the more chaotic and hormonal nature of the High School DxD characters. The High School DxD characters, on the other hand, would be intrigued by the Rangers' powers and technology. Issei, for example, might be eager to learn about the Rangers' combat skills and see if he could incorporate them into his own fighting style.
Ash, being the enthusiastic and determined trainer he is, would likely approach Roxie with great respect for her as a gym leader. He would probably be eager to learn from her about different Pokemon types and battle strategies. Roxie, on the other hand, might be initially a bit reserved but would gradually warm up to Ash's energy.
The characters would likely have a mix of confusion and fascination. For instance, Harry Potter might be intrigued by the unique powers of the devils in High School DxD like Issei's Boosted Gear. On the other hand, the devils in DxD could be in awe of the complex magic system in the Harry Potter world. They would have to communicate and find common ground to work together, which could lead to some interesting cultural exchanges.
Well, Ben could use his alien forms to help out the characters in High School DxD in battles. For example, if there's a fight against a powerful devil, Ben could transform into Four Arms and use his super strength. The characters in DxD would be amazed by his abilities.
Ash is adventurous and always eager to catch new Pokemon and become a better trainer. Apple Bloom is more about learning new things in her own world. When they meet, Ash might share his Pokemon experiences with her, like telling her about different regions and the unique Pokemon there. Apple Bloom could be really curious and ask a lot of questions. She might also show Ash some of her own skills or knowledge from her world, which could be something new for Ash.
Their interaction might also involve some cultural exchange between the Pokemon and Digimon worlds. Ash could introduce Kari to Pokemon treats and how to care for Pokemon, while Kari could show Ash some of the unique digital technologies in the Digimon world. They might even exchange stories about their adventures and the friends they've made along the way, which could strengthen their bond and help them work together better.
Ash would first have to adapt to the different species and power levels. In Pokémon, he's used to battling Pokémon, but in High School DxD, he'd be facing devils, angels, and fallen angels. He'd likely use his quick - thinking skills from his Pokémon battles to assess new situations. For example, when facing a devil's magic attack, he might quickly analyze its pattern and try to find a way to counter it, just like he does with Pokémon moves.
Pit from Kid Icarus is very innocent and pure - hearted. He would be quite shocked by the more lust - driven characters in High School DxD like Issei at first. But over time, his positive attitude might influence Issei to be a bit more noble in his pursuits.
They could interact in a competitive way at first. Characters from Mars and Jupiter might challenge Ash to Pokemon battles to test his skills. As the story progresses, they realize they have a common goal, like protecting the Pokemon universe from a greater threat. So, they start to cooperate, with Ash's determination and the unique skills of the Mars and Jupiter characters combining to form a strong alliance.
Their relationship could become more competitive in high school. With both of them having their own goals in the Pokemon world. They'd constantly try to outdo each other in various school - related Pokemon activities. But this competition would also make them respect each other more in the long run. Ash might learn new strategies from May's contest - based approach, and May could pick up some battle - hardiness from Ash.
