A character in Undertale and Deltarune and the son of Asgore and Toriel, Asriel resembles a humanoid goat-like monster, and is primarily seen wearing a green and yellow striped shirt and black pants as portrayed in Undertale.
In Undertale, he died long before the events of the game and reincarnated as Flowey due to Alphys injecting Determination into one of the golden flowers that happened to contain his essence. During the "True Pacifist" route of the game, he takes on the role of the final boss as the God of Hyperdeath after absorbing everyone's souls.
In Deltarune, he was mentioned multiple times throughout the story, though he has yet to make an appearance until after a week in the game's setting since he is studying for college.
