Perhaps the 'sucker' is a charm in disguise. Harry Potter, being curious, eats it and then finds himself in a whole new adventure. He might be transported to a different part of Hogwarts that he's never seen before, or even to a different magical realm altogether.
Well, it's a very strange concept. Maybe in this fanfiction, the 'sucker' is some kind of magical candy that has a really unexpected effect on Harry Potter. For example, it could make him start speaking in a strange language or have some wacky magical abilities for a short time.
In this fanfiction, the 'sucker' could be a prank item created by the Weasley twins. Harry, not knowing what it really is, eats it and then has to deal with all sorts of comical situations like his hair turning into snakes or his voice getting really high - pitched. It could be a really fun and light - hearted take on the Harry Potter universe.
Well, he might start breathing fire! Ghost peppers are extremely hot, and Harry's magic might not be able to prevent his mouth from feeling like it's on fire. His face would probably turn bright red, and he'd be gasping for water or some kind of cooling spell.
Well, if Harry Potter ate the Ope Ope no Mi in a fanfiction, he might gain the ability to create a 'room' and perform surgical - like operations. He could use this power in his battles against Voldemort. For example, he could isolate Voldemort in a 'room' and then use his magic to try and defeat him without harming others around.
Maybe the author wants to create a humorous situation. Harry Potter is such a well - known and serious character in the original series, and having him eat a sucker just turns that on its head and makes for a really funny scenario. It could also be a way to introduce a new magical item into the fanfiction world that the story then revolves around.
Well, if Harry ate a devil fruit in fanfiction, he might gain some extraordinary powers. For example, if it was a Logia - type devil fruit, he could transform into an element like fire or water. This would completely change his abilities and how he interacts with the world around him. He could use these new powers to fight against his enemies in a whole new way.
Well, Harry could get involved in some really off - the - wall pranks. Since he's bored, he might decide to play some elaborate tricks on his friends, like magically changing their voices during class.
In fanfiction, if Harry Potter disappears, it could lead to chaos at Hogwarts. His friends like Hermione and Ron would likely be on a desperate search for him. They might suspect the Dark forces at work again, and start investigating all the possible places where Harry could have been taken or hidden.
In fanfiction, Harry Potter could be wrongly accused of using dark magic in court. Maybe some false evidence is presented against him, like a planted dark magic item. And he has to fight to prove his innocence.
Well, it could be a meeting between Harry and some long - lost relative. Maybe a wizard from a far - off land who has a connection to his family. It could bring new revelations about his past and powers.
In fanfiction, the possibilities are endless. It could be that they go on an adventure to a previously unknown magical land or face a powerful dark wizard who was thought to be defeated.
Well, it could go in many directions. They might travel to a previously unknown magical realm or encounter creatures that were only hinted at in the original series.
