The plot could involve Emil and Richter exploring different magical or historical places. Maybe they are on a quest to find a lost relic that has the power to save their world. Along the way, they could encounter various mythical creatures and face challenges that test their friendship and skills.
They could encounter wise old sages. These sages might offer them advice on their journey or give them clues about their destination. Another type of character they could meet is the bandit. Bandits would try to rob them, forcing Emil and Richter to either fight or use their wits to escape.
One possibility is that Naruto enters an AU where chakra doesn't exist. Instead, there are other forms of power. He would have to learn how to use this new power from scratch. Also, the relationships between different ninja clans could be very different. Naruto might end up making new alliances and enemies based on this new dynamic. This could be a great opportunity for character development as he faces challenges that are completely different from what he's used to in his original world.
He could meet an AU version of Hinata who is more assertive and outgoing. Maybe she's a powerful ninja in her own right and not as shy as in the original story.
One interesting plotline could be that in the alternate universe (au), Harry Potter discovers a world where magic is used in completely different ways. For example, instead of using wands, they use amulets. Another could be that he finds himself in a world where Voldemort won the war in his own universe, and he has to figure out how to change things in this au. Or perhaps he travels to an au where Hogwarts is a school for all magical creatures, not just witches and wizards.
Well, he could find himself in an AU where the Hogwarts houses are based on different criteria. He might then have to help students adjust to this new system. He could also stumble upon a world where the Deathly Hallows have a different significance or are even unknown. This would lead him on a quest to understand their new meaning and how they relate to the balance of power in that universe.
Ava von Richter in 'Ava von Richter based on a true story' is most likely a real - life person whose story has been adapted. She could be a woman who overcame great odds in her life. For instance, she could have been a survivor of a difficult historical event, like a war or a natural disaster. Her story might include how she rebuilt her life, how she found strength within herself, and how she influenced those around her. It's also possible that she was known for her creativity or her kind heart, and the work aims to showcase these aspects of her.
His character could be more carefree. In a different AU, he might not have the burden of fighting Voldemort. So he could be more relaxed and focus on things like magical research or teaching without the constant threat of dark forces. For example, he could be more experimental with his teaching methods at Hogwarts.
Common characters he could meet include an au Ginny who is a powerful seer. There might be a Hagrid who is a tiny, timid man instead of the large, boisterous one we know. He could also encounter an au Sirius Black who is a Death Eater, which would be a shocking twist. Additionally, he may run into an au Professor McGonagall who is more of an artist than a Transfiguration teacher.
In fanfiction, 'au' is short for 'alternate universe'. It allows fans to explore different 'what - if' scenarios. For instance, in a Supernatural AU, the characters could be normal humans instead of hunters. Writers can change character relationships, like Sam and Dean being estranged instead of the close brothers they are in the original show. It gives a lot of creative freedom to play around with the source material in new and exciting ways.
