Another theme could be adventure - related. Since they are both characters from the game Undertale which has an adventure - based storyline. They might go on adventures together in the fanfiction, facing challenges and growing closer as a result. Maybe they team up to save the Underground from a new threat or something similar.
Love and friendship is also a very common theme. Writers often depict how their relationship develops from being just acquaintances in the game to something deeper, whether it's a romantic relationship or a very strong friendship. This can involve things like them having heart - to - heart conversations, or doing things for each other that show their care and affection.
One common theme is friendship. Papyrus and Undyne are often shown building a strong bond of friendship through various adventures or just daily interactions in the Underground. Another theme is mutual respect. They both recognize each other's strengths, like Papyrus admires Undyne's fighting skills and Undyne respects Papyrus's determination.
One common theme is friendship. Since their relationship in the Underswap world is different from the original, fanfics often explore how they become friends first. For example, they might bond over a shared interest in cooking or training.
Some fanfictions focus on their backstories. Writers might create stories about how they first met, what their initial impressions of each other were, and how their relationship has evolved over time. This can add more depth to their characters and make the readers understand them better.
The contrast between their personalities. Undyne is strong and fierce, while Papyrus is kind - hearted and a bit naive. When these two are paired in a fanfic, it creates a lot of interesting dynamics. For example, Undyne might protect Papyrus in a fight, and Papyrus would be there to comfort her with his gentle nature.
Overcoming challenges is also a big theme. Maybe there are challenges in their relationship due to differences in their nature (Undyne being a tough warrior and the reader perhaps being more timid). Or they might face external challenges like threats from other characters in the Undertale world, and they have to work together to overcome them and in the process, their relationship deepens.
There's also a fanfiction that delves deep into their backstories. It shows how Papyrus and Undyne first met and how their initial impressions of each other changed over time. It's really interesting as it gives a lot of depth to their relationship. It also has some great dialogue that really captures their personalities.
Redemption is another theme. Chara is often seen as a more morally ambiguous character, and fanfictions might explore how Papyrus could influence Chara towards redemption. Papyrus's strong sense of right and wrong could play a big role in this kind of story.
Well, 'The Red and the Blue' is a great one too. It delves deep into their backstories and how those past experiences shape their relationship. The story shows how Undyne's boldness and Papyrus' kindness complement each other. It's a bit more of a slow - burn story, but it's really well - written and engaging.
The theme of growth is often seen. Both characters grow as individuals within the relationship. Alphys may become more outgoing and Undyne may become more empathetic. Also, the theme of adventure in their relationship is present in some fanfictions, where they go on adventures together in the Underground, strengthening their bond along the way.
Growth is also a common theme. Frisk may grow in confidence and strength under Undyne's influence, while Undyne might become more understanding and less hot - headed because of Frisk. And of course, there's the theme of adventure. Since they are in the Underground world which is full of mysteries, many fanfictions have them going on adventures together, facing monsters and solving puzzles.
