Batman joining the Dark Side would mean a complete shift in the power dynamics of Gotham. The police force, which has had an uneasy relationship with Batman at times, would be in a state of panic. They would no longer be able to rely on him as an ally, and would have to deal with a much more dangerous vigilante - turned - villain. His knowledge of Gotham's underworld and all its secrets would now be used to his own advantage, rather than to protect the city.
Well, his relationships would be turned upside down. Commissioner Gordon would feel betrayed. Batman has been a symbol of hope for the city, and now he's a threat. His enemies like the Joker might not know how to react at first. They're used to Batman being their adversary. But with him on the Dark Side, the Joker might feel like he has to step up his game or risk being overshadowed. Batman could start making deals with other villains, using his resources and influence to gain more power.
If Batman joins the Dark Side in fanfiction, his moral compass would be completely askew. He's always been a character defined by his strict code of ethics. Without that, he could start to target innocent people who he believes are part of the 'corruption' in Gotham. His actions would cause a ripple effect throughout the city. The public's perception of heroes would be shattered. And the other heroes in the DC universe would likely have to step in to try and stop him, leading to some epic battles. But it would also be a very interesting exploration of the character, seeing how far he could fall from grace.
One possibility could be that Batman's sense of justice becomes warped. He might start using more extreme and unethical methods to 'clean up' Gotham. For example, he could be more brutal with criminals, foregoing his usual no - kill rule. His relationships with his allies would also be severely strained. Alfred would be deeply disappointed and the Bat - family might split apart as they try to oppose his new, darker path.
If Harry Potter joins the dark side in fanfiction, it would completely颠覆 the original story. His friends would become his enemies, and Hogwarts would be in chaos. The power dynamics in the wizarding world would shift, and Voldemort might see Harry as a valuable ally or a potential threat to his own leadership. It's a very interesting concept to explore in fanfiction.
If Batman were to join Darkseid, it would be a huge shift in the DC universe. Batman is known for his strong moral code and fighting against evil. Joining Darkseid would mean he has to abandon his principles. Maybe he's forced to do it under some mind - control or a desperate situation to save Gotham in a way he thinks only Darkseid can help. But it would also make him a target for all his former allies, like the Justice League.
His relationship with Alfred would be severely strained. Alfred has always been Batman's moral compass and a source of support. If Batman joined the Dark Side, Alfred would be heartbroken and would try his best to bring Batman back to the light. There would likely be many arguments between them as Alfred tries to remind Batman of his true values.
Well, one possibility could be that Harry, feeling betrayed by the Order of Phoenix or perhaps influenced by some dark magic artifact, starts to question the motives of the good side. He might see how the Dark side offers power and a different kind of 'freedom'. For example, Voldemort could manipulate Harry by showing him how the wizarding world could be united under his rule, eliminating the in - fighting among pure - bloods, half - bloods and Muggle - borns, though of course this would be a false promise.
One possibility is that Batman would bring his detective skills to the Avengers. His ability to analyze a situation and find clues is unrivaled. He could help the Avengers solve mysteries that they might not be able to on their own. For example, if there was a villain leaving behind complex riddles or hidden messages, Batman would be the one to crack them. Also, his martial arts skills would be a great addition to the team's combat capabilities. He could train some of the Avengers in different fighting styles, enhancing their overall performance in battles.
In such a fanfiction, Anakin would likely remain a Jedi. He would continue to fight for the Republic and the Jedi Order. He might have a more positive influence on the Clone Wars, perhaps finding a way to end the conflict more peacefully. His relationship with Padmé would also be different, not marred by his fall to the dark side.
In fanfiction, Anakin joining the Dark Side often has complex motives. It could be due to his fear of losing Padmé. The Dark Side might seem to offer him a way to save her, so he succumbs to its power.
If Naruto joins the Dark Brotherhood in a fanfic, he could bring his unique ninja skills. His shadow clones, for example, could be used for various sneaky missions the Brotherhood undertakes. However, his positive and optimistic nature might be a threat to the Brotherhood's more secretive and often amoral operations. The Brotherhood would either have to adapt to him or try to corrupt his good nature.
Perhaps Harry discovers some dark secrets about the wizarding world that make him lose faith in the good side. For example, he might find out that some of the so - called good wizards have been involved in immoral acts. This disillusionment leads him to think that the dark side might be a better option. As he joins them, he starts to abuse his power, using dark magic to get revenge on those who he believes have wronged him.
