One idea could be that Morty discovers a way to redeem Evil Morty. He tries to show Evil Morty that there's a better way than his villainous path. Morty could use his own experiences of growth and kindness to reach out to Evil Morty.
A fanfic could explore a scenario where Evil Morty has a change of heart because of Morty. Morty's unwavering belief in the good in people, even in the darkest of characters like Evil Morty, could be the catalyst for this change. Morty might show Evil Morty the value of family and friendship that he has been missing out on.
Perhaps a plot where they are forced to team up against a greater threat. This could lead to some interesting character development as they have to put aside their differences. They might start to understand each other's motives better during the process.
Well, an 'Evil Morty' fanfic in the 'Rick and Morty' universe can be really interesting. Evil Morty is such a complex character. In these fanfics, he could be explored further in terms of his motives. Maybe he's tired of being in Rick's shadow or he has some grand plan to take over the multiverse that wasn't fully shown in the show. Fanfics give the writers the freedom to expand on his backstory and what makes him tick.
One more thing that makes these fanfics unique is the way they can twist the relationships in the show. Evil Morty's presence can change the dynamics between Rick and Morty. For instance, Morty might start to question Rick more if he sees what an Evil version of himself is capable of. And Rick might have to reevaluate his relationship with Morty in light of this new threat. This creates a whole new set of story possibilities that are unique to these fanfics.
One idea could be a fanfic where Rick and Morty get stuck in a dimension where time runs backwards. Another could be about Morty becoming a super - intelligent scientist like Rick for a day. Maybe a fanfic where they meet alternate versions of themselves who are complete opposites in terms of personality.
In such a fanfic, one aspect could be how Jessica views Morty. She might initially be dismissive or not even notice him, but as the story progresses, she could start to see his hidden qualities. Also, the fanfic could play with the different dimensions in Rick and Morty. For example, there could be a dimension where Morty and Jessica are already a couple, and Morty from our main dimension tries to learn from that version of himself to win Jessica in his own world.
By putting them in situations where they have to rely on each other. For example, if they are trapped in a dangerous dimension. This would force them to interact and potentially grow closer.
One idea could be a time - traveling adventure where Summer and Morty end up in a parallel dimension where their roles are reversed. Morty is the confident, popular one and Summer is the nervous sidekick for a change.
One idea could be an OC who is a brilliant scientist from another dimension, but with a very different moral code than Rick. They could start as an adversary but then form an unlikely alliance. For example, this OC might believe in using science for the greater good of their own dimension in a way that Rick would find naive.
The 'Rick and Morty' universe is so wild and full of possibilities. Fanfiction allows writers to explore different scenarios for Summer and Morty that might not be shown in the actual show. For example, they could be in a situation where they have to save the entire multiverse, which would be a great adventure to read about. It also gives a chance to develop their characters further and see how their relationship might change in various circumstances.
One possible plot is that Morty gets a device from Rick that can make him more appealing to Jessica. But things go wrong, and instead of attracting her, he ends up making a fool of himself in front of her. Another plot could be that Jessica gets into some kind of trouble, and Morty has to step up and be the hero to save her, which makes her see him in a new light.
There could be a fanfic where Rick and Morty accidentally swap bodies. This would lead to a lot of comical situations as they try to adapt to each other's lives. Morty - in - Rick's - body might struggle with handling Rick's advanced technology, and Rick - in - Morty's - body would have to deal with Morty's school and family life in a very different way.
