Can you recommend some interesting 'undertale x deltarune fanfiction'?

One interesting concept could be the crossover of characters' personalities. For example, how the determination trait from Undertale might interact with the more mysterious elements in Deltarune. Another could be the exploration of different timelines. Since both games have some elements related to time and alternate realities, a fanfic might delve into how these timelines could cross or affect each other. Also, the unique magic systems of both could be combined in creative ways, like how the soul powers in Undertale might work with the magic in Deltarune.

Another plot idea is a story where the antagonists from both games, such as Flowey from Undertale and the King from Deltarune, form an alliance. Their goal could be to take over both universes. This would force the heroes of both games to work together. The fanfic could explore how the different characters with their own powers and personalities interact and strategize to defeat this powerful alliance.

One idea could be that the characters from Undertale find themselves in the world of Deltarune. For example, Frisk could end up in the Dark World and have to figure out how to get back home while interacting with the Deltarune characters. They might team up with Kris to fight against new threats that are a combination of both universes' villains.

One common theme is the exploration of the differences and similarities between the two worlds. Since Undertale and Deltarune have different settings and rules, fanfictions often play with how the characters react to these differences. Another theme is friendship. Characters from both games often form new friendships or strengthen existing ones across the world boundaries.

Maybe in the fanfiction, the Dark Fountains from Deltarune start appearing in the Undertale world. This causes chaos as the monsters in Undertale don't understand what these strange fountains are. Frisk, along with the Deltarune trio, has to figure out how to stop the fountains from spreading darkness. They could learn from each other's powers and strategies. For example, Frisk could teach Kris about determination in a more in - depth way, and Kris could show Frisk how to navigate the strange new areas created by the Dark Fountains.

One idea could be that the characters from Undertale find themselves in the Deltarune world and have to adapt to its different rules and characters. For example, Sans could meet Ralsei and they could have a humorous exchange about the nature of their respective universes.

It could be seen as a form of cultural exchange within the same fictional realm, and Deltarune might even learn something new about the Undertale characters or concepts from it.
