They're popular because it's a cool concept. It gives Harry a new dimension. Instead of being the normal Harry who is often in the dark about things, he becomes this super - knowledgeable character which is exciting.
There's a fanfic called 'Harry's Omniscience'. In it, Harry's all - knowing ability makes for some really unique plot twists. For example, he is able to foresee certain events that were going to be disastrous and takes steps to prevent them. It also changes his relationships with other characters as they start to rely on his knowledge more and more.
In fanfiction, 'Harry Potter remembers everything' can be a really interesting concept. It might mean that Harry has a perfect recall of all his experiences, including the traumas. This could lead to him being more strategic in dealing with Voldemort and his followers. For example, he could remember every detail of a Death Eater's spellcasting pattern and use that knowledge to his advantage in battles.
One consequence could be that Harry feels an internal struggle. Since he has a part of Voldemort's soul in him, he might have to constantly fight against the dark impulses that come with it. For example, he may find himself having more aggressive thoughts or being more easily influenced by dark magic in certain situations.

Definitely. The idea of Harry Potter, a wizard from the magical world, meeting Tony Stark, a genius inventor from the Marvel Universe, has a great potential for exciting stories.

In Harry Potter fanfiction, time can change everything by allowing characters to grow and develop. For example, as years pass, young wizards become more powerful and experienced. Their relationships also evolve. Friends might become enemies or vice versa over time. The wizarding world itself can change, with new spells, creatures, or political situations emerging as time goes on.
There might be a new dark wizard or witch that we don't know in the main series. This new character could be extremely powerful and target Harry specifically. They might have a vendetta against Harry's family or just want to take over the wizarding world by first destroying Harry, who is seen as a symbol of hope, and thus make him lose everything.
It could be about exploring a power within Harry Potter that he's not aware of yet. Maybe it's a new magical ability or a hidden strength related to his character's arc or his family heritage in the fanfiction world.
In a fanfiction scenario where Harry Potter knows the Joker, it would be a very interesting crossover. Harry, being used to a certain code of ethics in the wizarding world, might be shocked by the Joker's complete lack of moral boundaries. He could attempt to reform the Joker using magic, perhaps a spell to make him see the error of his ways. On the other hand, the Joker might see Harry as just another plaything in his game of chaos and try to break Harry's spirit.
