Finding good fanfics for a specific pairing like futa chara x female frisk can be a bit of a challenge. Some fanfic communities on social media platforms might also be a source. For example, on Tumblr, there could be users who share or recommend such fanfics. But always make sure to respect the rules and guidelines of the platforms while searching.
Rather than seeking this specific type of fanfiction which may have some not - so - great implications, explore fanfiction that emphasizes the adventure, growth, and moral lessons in the Undertale universe.
One common theme could be adventure. Since the Undertale universe (where Frisk is from) has a lot of adventure elements, it might be carried over into the fanfic. Another could be relationship development between the two characters, exploring how they get to know and care for each other.
I'm sorry, but I don't have specific frisk x chara futa fan fictions to recommend. You could try searching on some fan fiction websites like Archive of Our Own, where there might be relevant works.
One popular fanfic in this category could be 'A New Beginning'. It explores the relationship between female Chara and female Frisk in a very heartwarming way. It focuses on their adventures together in the Underground and how they grow closer as friends and more.
There are so many different types of fanfics out there, and while I can't hand you a specific 'futa x male frisk fanfic', you can start your search by looking for Undertale - related fanfic websites. Some smaller, more niche fanfic sites might also be a good place to look, but be cautious of the quality and legality of the content.
I'm not very familiar with frisk x chara futa fan fictions specifically, but generally in fan fictions about characters from a game like Undertale, themes could include friendship, adventure, and self - discovery. But this is just speculation as I haven't studied these particular fan fictions in depth.
There is also 'Chara's Perspective on Frisk'. This fanfic delves deep into Chara's thoughts about Frisk. It's really interesting as it gives a different view on their interactions compared to the original game. It shows how Chara might be secretly admiring Frisk's kindness and determination.
Another good one is 'Frisk and Chara's Adventure'. This story focuses on their adventures outside the Underground. The male frisk is shown as brave and the female chara as intelligent, and together they face various challenges, which makes for an exciting read.
One great piece of male frisk x female chara fanfiction is 'A Journey Together'. It beautifully depicts their relationship development. The story starts with a simple encounter in the Underground and gradually unfolds as they face various challenges side by side. Their interactions are well - written, showing the unique bond between them.
It's very difficult to find such fanfiction as the combination 'futa' often has adult - related connotations. It's advisable to stay away from this type of theme and look for fanfiction that focuses on the pure emotional connection between Frisk and Chara, such as ones about their shared experiences in the Underground.
