Asriel and Chara have a complex and tragic story in Undertale. Chara was a human who fell into the Underground. They became friends with Asriel, the prince of the monsters. They had grand plans to free the monsters by using Chara's soul. However, things went horribly wrong. Chara's plan involved sacrificing themselves, but when Asriel tried to carry out their final wish, the humans attacked him, thinking he had killed Chara. Asriel was too kind-hearted to fight back and died as a result.
One important event is when Chara first fell into the Underground and met Asriel. Another is their decision to try and free the monsters together. And of course, the tragic event when Asriel carried Chara's body to the surface and was attacked by humans.
Well, it's not really acceptable. The Undertale community is supposed to be inclusive but also appropriate. Fan fiction should focus more on the positive aspects of the game, like the story, the characters' development, and the unique world it presents. NSFW content, especially with a sexual orientation focus like 'gay' in this case, can make a lot of fans uncomfortable and may even violate community guidelines in many platforms.
The fandom can enforce strict community guidelines on the platforms where fan works are shared. Moderators can actively look for and remove any NSFW content, including those with a 'gay undertale' theme. Also, fans can report such inappropriate works when they come across them.
One interesting Undertale fan fiction is 'Flowey's Redemption'. It explores the idea of Flowey getting a second chance at being a good being. Another is 'The Underground's New Era' which imagines a future where the monsters have fully integrated with the human world. And 'Chara's True Intent' delves deeper into the character of Chara, giving different perspectives on their actions in the original game.
There's a fan fiction called 'Toriel's Garden of Hope'. In this story, Toriel uses her magic to create a huge garden that not only provides food for the monsters in the Underground but also becomes a place of peace and healing. It's a really heartwarming take on the character of Toriel. Another one is 'Sans and the Multiverse'. This fan fic takes Sans on an adventure across different universes within the Undertale multiverse, encountering different versions of the characters he knows and having to deal with all sorts of crazy situations.
Sans is often a popular character. His laid - back yet mysterious nature can be really interesting to explore in the context of undertale overgrowth. He might use his unique abilities in different ways in this new setting.
Undertale music fan fiction is an interesting concept. It combines the love for the game's music with the creativity of writing. In these fan fictions, the music can act as a driving force for the plot. Imagine a story where a character is haunted by a melody from Undertale, and they have to go on a journey to find out the origin of that music. It could also be about how different characters interact with the music. Maybe a monster in the game has a special connection to a certain track, and the fan fiction delves into that relationship. It's a great way for fans to expand on the Undertale universe using the power of music.
