Demise appeared in 2016 videogame called Monster Legends. Demise was the Princess of the Underworld until, one day, she felt the sunlight for the first time. She then ran away to the land of the living with her pet skull Manuel and became the protector of its inhabitants.
Demise is a nice support with decent speed and great skills, and doesn't often fail. The rest of her isn't particularly good -not to say outdated- but for how old she is, she's surprisingly great.
