Asriel is an anthropomorphic goat boss monster. He bears a strong resemblance to his father with his horns, facial hair and floppy ears. He wears a satchel slung over his shoulder, presumably for work purposes. He also wears a heart locket around his neck.
His informal outfit consists of a green t-shirt, black shorts and no shoes.
For his formal outfit, he wears a purple jacket over his shirt, long pants and purple boots.
Asriel has never seen his father, since he was born after his parents Asgore and Toriel went their separate ways.
Asriel currently works as a business partner with Crossbones and publishes comics for him.
