Well, Naruto would probably become an even more formidable ninja. Batman's skills in strategy, detective work, and various combat techniques could enhance Naruto's abilities.

One challenge could be the difference in their combat styles. Naruto is used to using chakra and ninja techniques, while Batman relies on his physical strength and gadgets. Adjusting to Batman's style might be difficult for Naruto. Another challenge could be the difference in their moral codes. Naruto's is more about forgiveness and redemption, while Batman is more about vengeance and justice.

Well, Batman had multiple trainers. One of them was Henri Ducard. He taught Batman various combat and detective skills. Another was Jean-Paul Valley, who also had an impact on his training and approach.
It could be that the story focuses on how Izuku's character changes under Batman's training. Batman might teach him about the importance of preparation and having a backup plan. Izuku, on the other hand, could teach Batman about the power of hope and believing in oneself unconditionally.

The main characters would be Harry Potter and Batman. Harry Potter, the young wizard from the wizarding world, is the focus as he is being trained. Batman, the Dark Knight from Gotham, brings his skills and knowledge to the table. There might also be some appearances from other characters in the Harry Potter universe, like Hermione and Ron, who could react to Harry's new training. And in the Batman side, perhaps Alfred could also play a role, providing support or advice in the training process.
