What is Marlette?
Marlette AU is an alternate universe where Sans and Toriel have a child (without sex) named Marlette, and that takes place after the True Pacifist route of UNDERTALE. As Marlette grows up, she has to figure out her relationships with her family and herself.
Marlette is an UNDERTALE OC that I designed roughly around 2018. I never did anything with her until 2020, thanks to a friend of mine, CHAOS_FANTAZY, coming up with her name. Now I'm attached and I need everyone to know about her.
She even has a button to share around!! Please consider saving it to your site or something.
