Perhaps when he realizes that all his efforts to defeat the dark forces seem to be in vain. He has been fighting so hard, but the dark side just keeps getting stronger. This feeling of futility could drive him to his breaking point, making him question his whole purpose and existence in the wizarding world.
When he reaches his breaking point, Harry might become more withdrawn. He could stop trusting people as easily as he did before. For example, he may start to keep his own council and not share his thoughts and plans with his friends like he used to.
In fanfiction, when Harry Potter reveals himself, it could be a moment of great drama. Maybe he reveals his true identity to save his friends from a dangerous enemy. For example, if they are being tricked by a Death Eater in disguise, Harry might step forward and expose himself to stop the harm.
Well, one possibility could be Itachi as a wizard in the Harry Potter world. Maybe he'd be in Slytherin due to his cunning nature. He could use his Sharingan abilities in a magical way, like seeing through invisibility cloaks or detecting hidden spells.
I'm not sure specifically as there could be many different 'Breaking Point' Harry Potter fanfictions. It might be about a moment where a character reaches their breaking point, perhaps Harry dealing with the stress of fighting Voldemort, or Hermione struggling with the pressure of schoolwork and the wizarding world's problems.
In some fanfictions, Harry might become a very influential Auror, traveling around the wizarding world to fight dark magic remnants. He could also be involved in reforming the Ministry of Magic, ensuring fairness and equality for all magical beings.
In the fanfiction, Harry squinting at Wormtail might also be a moment of intense focus. Harry could be trying to use his Legilimency skills (if he has developed them in the fanfic world) to read Wormtail's mind. He's squinting as he concentrates, trying to break through any mental defenses Wormtail might have. It could be a crucial moment in the story where Harry's discovery of Wormtail's thoughts could change the course of events.
In such a fanfiction, one possibility could be that Harry Potter defies Dumbledore over the use of certain dark magic items. Maybe Harry believes that Dumbledore is being too cautious and that these items could be used for good in the fight against Voldemort. For example, he might think that the Elder Wand could be harnessed in a different way than Dumbledore anticipates.
Well, one scenario could be that Harry moves out to escape the constant media attention in the wizarding world. He might find a quiet cottage in the countryside where he can practice magic in peace.
Perhaps Harry faked his death with the help of his friends. Hermione, being extremely intelligent, could have come up with a plan. They might have used polyjuice potion to create a false body that looked like Harry's dead body. This would mislead the enemy and give Harry the element of surprise in the ongoing battle against the dark forces.
One possible scenario could be that Harry uses Polyjuice Potion to create a false body that appears to be his dead self. He might do this to deceive Voldemort and his Death Eaters, giving him the element of surprise to strike back later. Another scenario could involve elaborate magical illusions created with the help of his friends, like Hermione's extensive knowledge of spells and Ron's courage in the face of danger. They could set up a staged death scene that looks very real to the outside world.
