A possible plot is that they are thrown into a dangerous situation together. As they work side by side to survive, memories of their time as a couple resurface. Qrow might be a bit more protective of Amber due to their history, and Amber could start to see the good in Qrow that she had forgotten.
Well, the plot could involve them reminiscing about their past relationship. Maybe they meet again after a long time and there are still some lingering feelings. They could start to talk about what went wrong in the past and whether they can start anew.
The plot could also be about how their old relationship affects their current relationships with other characters. For example, if Qrow is now friends with someone who doesn't trust Amber, or vice versa. There could be a lot of drama and conflict as they try to navigate their old feelings and new loyalties.
Qrow is often a bit brooding and self - deprecating. Amber, on the other hand, is more positive. So, their personalities could create an interesting dynamic. Qrow might be drawn to Amber's light - heartedness, while Amber could be intrigued by Qrow's complex nature.
It could also be a more comical take. The 'bird bird fruit model' might be a misnomer or a really strange concept that Qrow has to deal with. For example, instead of giving him cool powers, it makes him do really silly bird - like things. And the fic could be about how he tries to get rid of this 'fruit model' effect while his friends and family have a good laugh at his expense.
In this fanfic, Naruto and Amber could have different goals at first. Naruto might be on a quest to find a way back to his own world, while Amber is trying to rescue her family or something. However, as they face the common enemy of the zombies, they realize that they need to work together. Naruto's chakra - based abilities could be a huge asset in dealing with the powerful zombies. For example, his Rasengan could be used to take out large groups of zombies at once. Amber, on the other hand, could be the one with the knowledge of the layout of the area in Dead Rising 2, guiding Naruto through the dangerous streets and buildings.
One possible plot could be that Naruto somehow gets transported to the RWBY universe. He witnesses Qrow's skills in battle and becomes an instant fan. He then tries to learn from Qrow, and Qrow, seeing Naruto's determination, decides to train him a bit. This leads to Naruto adapting some of Qrow's fighting techniques to his own ninja style.
A fanfic could revolve around a world where Amber Liu and Eric Nam are superheroes. They have different superpowers but are part of the same superhero team. They initially clash because of their different approaches to fighting crime, but as they get to know each other better, they realize they are stronger together and their relationship evolves from a rocky start to a loving and supportive one.
Perhaps a plot where the worlds of Harry Potter and RWBY are merging. Harry, as Qrow Branwen, is seen as a key figure in uniting the two worlds against a common threat. He has to bring together the magic of his original world and the combat abilities of the RWBY world to defeat an enemy that is powerful enough to destroy both universes. This would involve him recruiting characters from both worlds and finding a way to make them work together.
Well, it could be about Naruto having some of Qrow's characteristics. Maybe he has Qrow's combat skills or his sense of humor. For example, Naruto could inherit Qrow's scythe - using fighting style and combine it with his own ninja moves. It would make for some really interesting battles.
One possible plot idea could be a dance competition story. Amber Riley, known for her amazing vocal skills but also with a passion for dancing, teams up with Derek Hough, the brilliant dancer. They start off as strangers but gradually bond over their shared love for dance and the desire to win the competition. Along the way, they face challenges like difficult choreography and tough competitors.
One possible plot could be that Naruto, with the power of the Flame - Flame Fruit, becomes even more powerful in combat. He could use the fire - based abilities of the fruit to enhance his existing jutsu, like adding a flaming element to his Rasengan. This would make him a more formidable opponent against enemies, especially those with water - based techniques.
Perhaps a fanfiction where Amber is revived in some unexpected way. Autumn, who might have some connection to the afterlife in the RWBY lore, helps bring her back. Qrow then has to deal with the implications of Amber's return and the potential chaos it could cause in the world of Remnant.
