One way the worlds could collide is through a magical accident. Maybe a spell in the Harry Potter universe goes wrong and opens a portal to the Tokyo Ghoul world. The wizards could be shocked to see the ghouls with their kagunes. And the ghouls would be equally surprised by the magic of the wizards.
There could also be a situation where the two worlds are in danger and need to combine forces. The Death Eaters from Harry Potter could team up with some of the more malevolent ghouls in Tokyo Ghoul. In response, the Order of the Phoenix and the good ghouls like Touka could work together. This would create an interesting dynamic as they try to understand each other's powers and find a way to defeat the common enemy.
One way the worlds of Danny Phantom and Harry Potter could collide in a fanfic is through a magical accident. Maybe a spell gone wrong in the wizarding world creates a portal that leads to Amity Park. Danny, being the hero he is, gets sucked into the wizarding world through this portal.

Well, in a Tokyo Ghoul and Harry Potter crossover fanfiction, there could be a character who is both a ghoul and a wizard. This character would have to struggle with the dual nature of their existence.

They might use magic to try and control their ghoul instincts, like using a spell to suppress the urge to attack people.
One way their worlds could collide is through a magical portal. Maybe in a fanfiction, a powerful wizard in the Harry Potter universe accidentally creates a portal that leads to Middle - earth where Aragorn is. And Aragorn, being a brave and curious leader, steps through the portal to explore the strange new world of magic and wizards.
A plot might involve a magical accident that transports some of the Tokyo Ghoul characters into the wizarding world. Kaneki could end up at Hogwarts and be sorted into a house. He'd struggle to hide his ghoul identity while also trying to find a way back home. At the same time, the wizards are intrigued by his unique abilities and some, like the more power - hungry ones, might try to use him for their own gain. Harry Potter and his friends would then have to decide whether to trust Kaneki or not.
Hermione would probably be extremely curious about the ghouls. She'd want to study their biology, especially the kagune. She might even try to find a way to use her magic to help the half - human, half - ghoul characters like Kaneki deal with their identity crisis.
In a fanfiction scenario, perhaps Nick Fury is on a mission to recruit magical beings for S.H.I.E.L.D. He discovers the existence of the Harry Potter world and tries to make contact. Harry and his friends could be initially suspicious but then see the potential in working with Fury. They could exchange knowledge, with the wizards learning about Muggle technology and Fury learning about magic. This could lead to some really interesting team - ups and adventures against common enemies.
Well, it could start with a magical portal opening up in She - Hulk's world and sucking her into the Harry Potter universe. There, she might be seen as a strange and powerful being. The wizards would be both curious and a bit afraid of her. She - Hulk could then team up with Harry and his friends to face a common enemy, like a dark wizard who is trying to use her power for evil purposes.
The characters would interact in very unique ways. For example, Harry Potter might be initially cautious around the ghouls from Tokyo Ghoul. He's used to dealing with Voldemort and his Death Eaters, but ghouls are a completely different type of threat. Ken Kaneki, being a half - ghoul, could teach the wizards about the nature of ghouls, and in return, the wizards could show him some amazing magic spells.
