Asriel is a melancholic goat monster who lives in Waterfall. He is encountered in the RUINS.
(In Rolereverse, Asriel is swapped with Napstablook.)
Asriel has low self-esteem and possible anxiety or depression. He cries during battle, and apologizes if he thinks he's being impolite.
Asriel has red eyes and white fur. He has no horns and droopy ears.
He wears a sheet, and whenever the sheet falls off, underneath a white shirt and white pants can be seen. He doesn't wear shoes. After his Ruins encounter, he is seen wearing a pair of headphones.
