Well, perhaps Reverse Dipper has some knowledge or power that regular Dipper doesn't. So, when they meet, Reverse Dipper shows off a bit. But then they realize that they need to combine their skills. For example, Reverse Dipper is really good at something that Dipper is bad at, and vice versa. They could use this to their advantage when facing a common enemy or solving a problem that spans across their worlds.
In this fanfiction, it could start with Dipper being really skeptical of Reverse Dipper. But as they interact more, they find out that they have a lot in common, like their love for mystery - solving. They might even find out that their destinies are somehow linked. Maybe there's a prophecy in both their dimensions about two versions of Dipper coming together to save both worlds from a great evil. So, they have to put aside their differences and work together towards that goal. Along the way, they learn from each other's experiences and grow as characters.
One idea could be that Reverse Dipper, coming from his alternate dimension, initially confuses the regular Dipper. Maybe they start by arguing about who is the'real' Dipper. Then, they could team up to solve a mystery that involves both their dimensions.
One potential antagonist could be Bill Cipher from Reverse Dipper's dimension. He might have different motives or be more powerful in that realm and see the meeting of the two Dippers as a threat to his plans.
One idea could be that Reverse Dipper, who might have different characteristics in this reversed world, meets Mabel and they initially have a misunderstanding because of their different ways of thinking. Maybe Reverse Dipper is more cautious while Mabel is her usual exuberant self. They could go on an adventure where Mabel tries to teach Reverse Dipper how to have more fun and let loose.
Perhaps the fanfiction's plot is centered around a time - traveling experiment gone wrong. Bill Cipher seizes the opportunity when Dipper is involved in this experiment and uses his powers to reverse time in a strange and unpredictable way. Dipper then has to navigate through a world where time is out of order, and he has to face Bill Cipher at different points in time, trying to set things right and save the Gravity Falls world from a fate worse than death.
One idea could be that Dipper and Pacifica team up to solve a mystery in Reverse Falls that's been plaguing the town. Maybe it has something to do with the strange occurrences that are unique to Reverse Falls. They start off as reluctant partners but gradually grow to trust and rely on each other.
One idea could be that they start off as rivals but then find themselves in a situation where they have to team up to solve a mystery in Gravity Falls. As they work together, they begin to understand each other better and a strange bond forms between them.
Bill Cipher would be an interesting character to involve. If he shows up, he could be even more manipulative towards Reverse Dipper and Mabel. His chaotic nature could create a lot of conflict and drama. Reverse Dipper might be more vulnerable to Bill's tricks or perhaps more resistant in some unexpected ways. And Mabel would have to use her wits and kindness to try to counter Bill's evil plans.
I'm not entirely sure what specific 'Will Cipher Times Reverse Dipper Fanfiction' refers to. It could be a very unique or niche concept within the Gravity Falls fanfiction realm. Maybe it's about some sort of time - reversing adventure involving Bill Cipher and Dipper? Without more context, it's hard to say for sure.
Perhaps in the fanfiction, Arnold discovers a portal in his world that leads to Gravity Falls where he meets Dipper. Kryptos could be some kind of code or entity that exists in both their worlds. They start to investigate it together, facing challenges like strange creatures and obstacles set by the mystery of Kryptos. As they dig deeper, they learn more about each other's worlds and themselves.
One possible plot could be Dipper's struggle with his new identity. He might have to deal with how his friends and family react. For example, Mabel could be super excited to have a sister for a change. And Dipper would have to navigate a world that treats him differently as a girl, like different expectations in Gravity Falls' strange society.
One common theme could be role - reversal in their personalities. For example, Dipper might be more carefree and Mabel more cautious. Another theme could be exploring a different kind of relationship dynamic between them, like a more romantic - friendship hybrid.
