Ceroba Ketsukane

Fox lady from the fangame Undertale Yellow who also has really hard boss fights and likes to drain your max HP in her Genocide fight, and is the final boss of the Pacifist route. She is the wife of Chujin Ketsukane and the mother of Kanako Ketsukane, and best friends with Starlo. Her goal is to obtain the soul of the game’s protagonist Clover, in hopes of aiding in reviving Kanako after she fell down. She also wants to further Chujin’s legacy, as he passed away before the events of the game. In the Pacifist route it is revealed that she was the one who unintentionally caused Kanako to fall down due to her injecting a serum that contained an impure human soul. This was because Chujin told Ceroba to continue his work with creating a serum that can turn regular monsters into boss monsters, and Kanako was one of the few monsters that possessed the boss monster gene in order to make the perfected serum, thus motivating her goal to use Clover’s pure soul. Ceroba’s character was met with mixed reception from fans, with some either calling her a bad mother or a fox MILF. Sometimes the Undertale Yellow fandom also call her “The Roba”
