How can a 'Harry Potter divinity crossover fanfiction' be written effectively?

Well, you need to blend the magical worlds of both carefully. Make sure the characters' personalities remain true and the plot is engaging for fans of both franchises.

One idea could be that Voldemort tries to harness divine power to become invincible. He discovers an ancient artifact that has a connection to the divine realm and attempts to use it for his evil purposes. Another idea is that the gods send a messenger to Hogwarts to teach the students about a different kind of magic, the magic of the divine. This messenger could be a character from a mythological pantheon, like Hermes.

Use body language. Harry could be standing tense, his hands clenched into fists while he squints. This shows his determination. And for Voldemort, you can describe his reaction to being stared at in such a way. Maybe he sneers or his red eyes flash with anger. 'As Harry squinted, Voldemort's lips curled into a cruel sneer, his eyes flaring.' This creates a dynamic between them.

To write it effectively, you need to find a common ground for the two universes. It could be a shared criminal organization or a unique type of crime. Then, introduce the characters in a way that makes sense. Maybe start with the BAU team being called to London because of a series of crimes that seem to have a connection to the US cases they've worked on. As for the writing style, blend the more scientific and psychological tone of Criminal Minds with the fast - paced, deductive style of Sherlock. Let the characters grow and learn from each other during the story. For instance, Sherlock could learn about the importance of team dynamics from the BAU, and the BAU could pick up some new deduction techniques from Sherlock.

Build up the emotional context. Maybe Harry has just received some devastating news, like the loss of a dear friend. The shock combined with his physical state makes him faint. 'Harry's heart felt like it had been ripped out when he heard the news. His legs gave way beneath him as he sank into unconsciousness.'

You need to have a deep understanding of both the universes you want to crossover. Make sure the characters' personalities and the overall tone match.

You can start by looking on well - known fanfiction websites. Check the reviews and ratings of the fanfictions tagged as Harry Potter crossovers. High - rated ones are more likely to be well - written. However, be cautious of any inappropriate 'lemon' content. Some websites have filters that can help you find suitable ones.

Parody is another effective method. You can create a story that parodies the typical 'Harry Potter' plot. For example, instead of Voldemort being the big bad villain, it's a wizard who's obsessed with making everyone wear matching socks. The absurdity of such a change can be really funny. And when the heroes like Harry and his friends have to deal with this strange new 'threat', it can lead to all kinds of humorous situations.

First, understand the original characters deeply. Know their personalities, motives, and backstories. If you're making a character a murderer, there should be a logical and believable reason. For example, if it's a character that has always been on the edge of darkness, show the gradual descent. Also, keep the magic system and the world - building consistent with the original. Use vivid descriptions to set the mood, whether it's a dark alley in Diagon Alley or a spooky corner of Hogwarts.

Humor can be added through character quirks. Like Neville's clumsiness can be exaggerated in a funny way. For instance, he could accidentally trip over his own plant while trying to show it off in Herbology class. Also, using puns related to magic. For example, when someone says 'I'm so charmed, it must be the spell of good humor!'
