In addition to Glitchtale, Camila Cuevas has also worked on other Undertale fan creations. One of them is the LISA X Undertale Crossover Interlopers where Chara (Undertale) and Buddy (LISA) travel to other "Alternate Universes" and confront the characters in them, with Glitchtale's main antagonist Bete Noire being one of them.
Felipe Montero - better known by his online persona NyxtheShield - has also composed songs for other prominent fan animations and fan works in the Undertale fandom, including Jael Peñaloza's Underverse series.
Sans is Camila's favourite character.
Gael Rice, the voice actor for Undyne is also an animator himself, with many of his most prominent animations centered around Undyne herself, including a parody of "I'm the Bad Guy" from Wander Over Yonder.
