The theme of revenge often pops up. Harry may turn to the dark side seeking revenge for the wrongs he's suffered. And the theme of the dark vs. light within himself. He battles with his former self and the new, dark identity he has adopted. It's complex and makes for great storytelling.
One theme is the corruption of innocence. Harry was once seen as the 'Chosen One' for good, but as a Dark Lord, his innocence is corrupted. Also, there's the theme of redemption in some cases. Some fanfictions explore if Harry can be redeemed from his dark path. It's really fascinating to see how different authors handle these themes.
One common theme is the exploration of forbidden love. Since Harry and the Dark Lord are on opposite sides in the original story, their love in fanfiction is often seen as something that goes against the norm. Another theme could be redemption. Maybe Harry's love is seen as a way to redeem the Dark Lord.
Power is a common theme. Fanfictions often explore how the Dark Lord amasses and wields his power. Another theme is fear, as his presence instills fear in the wizarding world. Redemption can also be a theme in some, where the Dark Lord or his followers might have a chance at redemption.
One common theme is the corruption of power. It shows how Harry, once a symbol of good, can be swayed by the allure of dark magic and ultimate power. Another theme is the breakdown of relationships. His friends and former allies would likely react in different ways to his transformation, which adds a lot of drama. There's also the exploration of the nature of good and evil, as Harry's new role blurs the lines between what was once clearly defined in the original series.
A theme that frequently appears is redemption. Even in the 'Dark Lord Harry' scenario, there can be a journey towards redemption, especially in relation to his relationship with Fleur. It could be about Harry trying to find his way back from the dark side because of Fleur's influence. Also, there is the theme of identity. Harry's new identity as a dark lord clashes with his previous self, and this affects how Fleur sees him and how they interact.
Power struggle is a common theme. It shows how the Dark Lord tries to gain more power and how the good side tries to stop him. There's also the theme of fear, as the wizarding community lives in dread of the Dark Lord's return.
One common theme is the corruption of innocence. Since Harry starts as a child, it shows how his initial pure and naive self can be influenced by the allure of dark magic. Another theme is the power struggle. As he becomes a 'dark lord', there are battles for control within the wizarding world.
One common theme could be the subversion of the traditional heroic image of Harry. Maybe in these fanfictions, Harry is portrayed as being corrupted by dark powers, turning into a 'dark lord'. As for Hermione bashing, it might involve making her out to be overly bossy or her intelligence being misused in a negative way in the story.
The theme of self - discovery is quite prevalent too. As Harry travels through time, he discovers new aspects of himself and his powers. He may realize that he has more potential than he thought in the original timeline. Additionally, the exploration of different timelines and how they interact with each other is a common thread. This can lead to some really mind - bending and exciting plot developments.
Common themes include identity crisis. Harry being in such a relationship would question his own identity and values. Manipulation is also a theme, as the Dark Lord might try to manipulate Harry. And there's the theme of secrecy. They would have to keep their relationship a secret from their respective allies. This adds an element of mystery and danger to the story.
Power is a very common theme. Since he is a dark lord, many fanfictions explore how he gains, maintains, and uses his power. Another common theme is betrayal. His relationships with his followers or other powerful beings often involve elements of betrayal. And of course, the theme of darkness and evil, which is central to his character as a dark lord.
