He could start to explore the secrets of his parents' past more deeply. Since he's feeling so down, he might look for some kind of comfort or understanding in their history. This could lead him to discover new things about his family that give him strength.
Another plot could be that Harry begins to train himself in some forgotten or ancient magic. Since he's feeling isolated and depressed, he decides to take matters into his own hands and become stronger. He could find an old book in the Dursleys' attic or in the local library that contains the knowledge of this magic, and he spends his summer mastering it.
Maybe he tries to find a way to communicate with Cedric's spirit. Feeling guilty and depressed, he might think that by talking to Cedric, he can get some closure. This could open up a whole new world of magic and mystery in the fanfiction, as he delves into the realm of communicating with the dead.
In this fanfiction, Harry might be dealing with the aftermath of the Triwizard Tournament. He could be depressed due to the loss of Cedric, the return of Voldemort, and the general disbelief from the wizarding world.

There might be a fanfiction where in their fourth year, Harry and Hermione go on a secret adventure related to the Dark Arts that they suspect is connected to Voldemort's return.

I'm not sure specifically as there could be many different interpretations of a 'Harry Potter fourth year retribution' fanfiction. It might be about seeking revenge or justice for something that happened in Harry's fourth year at Hogwarts in the fanfic author's vision.
One possible betrayal in Harry Potter's fourth year could be when some students believed the false rumors about Harry being a cheater in the Triwizard Tournament. In fanfiction, this could be explored further. For example, Hermione might initially doubt Harry due to the overwhelming rumors, creating a sense of betrayal for Harry. However, as the story progresses, she realizes the truth and they reconcile.
A possible plot might be that Harry uses his Superman - like powers to help the wizarding world during times of peace as well. For example, he could use his super strength to rebuild parts of Hogwarts that were damaged in previous battles. Or he could use his flight to quickly transport important magical artifacts from one place to another. Also, there could be a plot where the wizarding community is initially afraid of Harry because of his non - magical powers, but he has to prove that he is still one of them and is there to protect them.
One interesting plot could be Harry and Tonks going on secret adventures during the summer. They might discover a hidden magical place that no one else knows about and have to protect it from dark forces. Another could be Tonks teaching Harry some advanced magic skills that he can't learn at Hogwarts, like a unique form of transfiguration.
A potential plot could be that Draco is tasked with finding Snape's secret daughter for some unknown reason. When he does, he's surprised by her resemblance to Snape in terms of her intelligence and determination. They begin to work together to solve a mystery related to Snape's past, which gradually builds a bond between them.
Well, in some fanfiction, during summer vacation, Harry might go on a journey to find a rare ingredient for a potion that could potentially cure a common wizarding illness. He teams up with Hermione and they travel to far - off magical places, facing various challenges along the way like dangerous spells and tricky magical traps. This not only tests their magical skills but also their friendship.
Romance is also a common theme. Harry's growing feelings for Cho Chang, and other potential romantic relationships among the characters are often explored in fourth year fanfiction. It adds an extra layer of complexity to the story as the characters are also dealing with the high - stakes events of the Triwizard Tournament.
One popular plot is about the behind - the - scenes of the Triwizard Tournament. For instance, a fanfiction might focus on the preparation of the tasks by the teachers and the magical creatures involved. It gives a whole new perspective on the tournament.
