His character could be more carefree. In a different AU, he might not have the burden of fighting Voldemort. So he could be more relaxed and focus on things like magical research or teaching without the constant threat of dark forces. For example, he could be more experimental with his teaching methods at Hogwarts.
Well, he could find himself in an AU where the Hogwarts houses are based on different criteria. He might then have to help students adjust to this new system. He could also stumble upon a world where the Deathly Hallows have a different significance or are even unknown. This would lead him on a quest to understand their new meaning and how they relate to the balance of power in that universe.
His relationships would be significantly different. With Ron and Hermione, he might not form the same close bond as in the original story. Since Dumbledore is more of an authority figure, Harry might be more aloof from his peers at first. But he could also attract different friends who are interested in Dumbledore's teachings.
His character could develop a greater sense of humility. If he encounters new and powerful magic or beings in his adventure, he'll realize there's always more to learn in the wizarding world. He may start to see himself as just a small part of a much larger magical universe.
In some fanfictions, Dumbledore is portrayed as a more mysterious figure, with his actions and motives not always clear. He might be shown as having hidden agendas that are gradually revealed throughout the story. For example, in a story where the wizarding world is facing a new and unknown threat, Dumbledore's actions to counter it might seem strange at first but are later understood as part of a grand plan.
In a fanfiction where Harry Potter is raised by Albus Dumbledore, there would be many implications. Harry would be surrounded by the headmaster's influence. He might have early access to the secrets of Hogwarts. Dumbledore could teach Harry about the Dark Arts in a more controlled way, so that Harry would be better prepared to face Voldemort. Their relationship would be more like father - son, and this would change the dynamics of many events in the original story.
Well, it would be extremely complicated. Dumbledore was the one who defeated Grindelwald. So, initially, Dumbledore might be very cautious around Harry. He would be constantly on guard to see if Harry shows any signs of following in Grindelwald's footsteps. However, Dumbledore also knew Harry well, so he might be conflicted. He could try to guide Harry more closely to ensure he doesn't go astray.
If Dumbledore traveled to the past and influenced important historical figures, it could change the political and social structure of the wizarding world. Say he convinced a key figure to support a different ideology. This could lead to different laws and norms in the present. It might also change the relationships between different magical communities, like how wizards interact with goblins or centaurs.
Batman in the Marvel Universe in fanfiction would likely have a different view of heroism. In DC, his brand of justice is very much his own. But in Marvel, where there are so many different types of heroes, from mutants to Asgardians, he might re - evaluate what it means to be a hero. He could become more of a mentor figure to some of the younger heroes like Spider - Man, teaching them the importance of preparation and using their brains as well as their powers. His costume might also change to blend in more with the Marvel aesthetic, perhaps taking on some elements of Iron Man's high - tech look or Captain America's patriotic colors.
A fanfiction could be about Snape's unspoken loyalty to Dumbledore. Despite their differences and the difficult tasks Dumbledore assigned him, Snape remained faithful. This could be explored through Snape's thoughts and internal monologues, showing his deep - seated respect for Dumbledore.
For Lily Potter, her husband James Potter might be a likely ally. He would support her in any conflict she has with Dumbledore. Also, her close friends from her school days could side with her. They know her well and would trust her judgment.
