A great plot could be that Alex discovers a long - lost spell book that contains spells that are considered forbidden in the wizard world. As she starts to explore the spells, she attracts the attention of an old and powerful wizard who wants to get his hands on the book. Alex then has to protect the book and herself while also deciding if she should use the powerful and dangerous spells.
Another storyline might be a time - travel one. They accidentally travel back in time and have to blend in with the past while also trying not to change history too much. During this, their feelings for each other start to change from just sibling - like to something more romantic.
A magical detective who is investigating some strange magical occurrences in the neighborhood that Alex gets involved in. This character could be really serious and by - the - book, which would contrast with Alex's more carefree nature.
A fanfic could focus on a gay wizard who discovers a new form of magic that is only accessible to those who embrace their true selves. He then has to convince the other wizards in Waverly Place that this new magic can be a great addition to their world, all while dealing with some who are prejudiced against his sexual orientation.
Some writers develop their relationship through shared adventures. They go on quests together, face dangerous magical creatures, and in the process, they grow closer. As they protect each other from harm, their bond deepens. Writers might also include some jealousy plots, like when one of them seems interested in another character and the other gets jealous, which reveals their true feelings.
The 'coming - out' trope is quite common. It shows the journey of the gay wizard as he reveals his identity to his friends and family, often with some initial shock and then acceptance. For example, his best friend might be initially surprised but then stand up for him against bullies.
Max Russo is also a character that might show up a lot in Gay Wizards of Waverly Place fanfiction. His mischievous personality can lead to all kinds of fun scenarios in a gay - wizard - centric story. And of course, there could be original characters created specifically for the fanfiction that become popular among readers.
One idea could be a story where the gay wizard has to hide his identity from his non - magical family while also dealing with the pressures of wizard school. Another could be a love story between two gay wizards from different magical families, facing the challenges of their families' rivalries.
One interesting crossover could be a magical school exchange. Wizards from the Harry Potter universe visit Waverly Place's wizard school and vice versa. They could compare and contrast their different magical systems, like how spells are cast or potions are made. It would be really cool to see Harry Potter characters interact with the Russo family and their friends.
The plot is crucial. A 'best' fanfic might have an engaging and unique storyline that still fits within the world of Wizards of Waverly Place. It could be a new adventure that Justin and Alex go on together, or a situation where they have to overcome a big challenge. Maybe it's a time - travel plot or a story about them dealing with a powerful magical creature. The plot should keep you hooked from start to finish.
