Geneva (River Person) is the wife of Gaster and mother of Sans and Papyrus. She doesn't make an appearence in Furytale, but does appear in its prequel, Echoes of the Mind. She's feisty and cunning, using her street smarts to her advantage. She is seen as this embodiment of kindness, as usually she's sweet and gentle with those who need help, unless she's with her friends or husband, then she becomes this dorky fiery skeleton that doesn't take no for an answer. She's super nerdy, having an intense love for anime and anything with a wholesome plot.  On the surface she was the head of public transportation, overseeing methods of travel and ensuring that they remain safe for both monsters and humans.

Her weapon of choice is a Sabre, which is a sword most commonly used in Fencing. She has graceful like moves as she swings at her opponents, her movements sometimes mesmerizing her opponents to distract them so she can take them down. She does use blasters like her husband, but she doesn't use them as much, since after having Sans, they drain her of too much magic and leave her helpless

[Geneva shouldn't sound too young. She has a fiery attitude, almost tsundere like. I don't have a headcannon voice for her, so feel free to put your own spin on this!]
