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.
Justin could be involved. He might be the one who either tries to help Alex get out of the forced lemon situation or, on the contrary, he could be the one who thinks she should just follow the rules. Another character could be Harper. She might be there to provide some comic relief while Alex is dealing with the lemon thing. For example, she could make jokes about Alex smelling like lemons all the time.
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.
I also liked when the Russo family had to compete in the wizard family competition. The different challenges they faced and the unique spells they used were really exciting. It showed how creative they could be with their magic.
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.
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.
In the fanfic, perhaps there's a spell gone wrong that forces Alex to be around lemons all the time. It could be that an enemy wizard casts a spell that makes her have an aversion to lemons but at the same time be constantly in their presence. So she has to figure out how to break the spell while dealing with the annoyance of the forced lemon situation.
Another story could be about Alex Russo traveling back in time to the early days of Waverly Place and accidentally changing something that affects the present. She then has to figure out how to fix it while dealing with the differences in magic use from that era.
It's likely about the adventures of the characters from 'Wizards of Waverly Place' in a graphic novel format. Maybe it shows their magical exploits, family dynamics, and the challenges they face as wizards, all presented in illustrated form.
A good 'Wizards of Waverly Place' fanfic often has well - developed characters. It should stay true to the personalities of the characters from the show, like Alex's sassiness or Justin's studiousness. Also, an interesting plot is key. Maybe it could be about a new magical adventure that the Russo family goes on.
