Asriel Dreemurr was the first Monster to meet Chara when he fell into the underground. After a failed plan to free the Monsters, he died and was resurrected as a soulless flower. He is later given a soul with all seven traits, from Chara, near the end of Season 1, which returns him to his original form.
Appearance
Classic
Asriel is a male Boss Monster that has a goat-like appearance. He wears a green and yellow-striped shirt, with brown pants and dark brown shoes. His eyes are naturally green. When in battle, he can tap into his "Hyperdeath" powers. His sclerae turn black, his irises turn white, and a black face marking grows on his face.
When under HATE's influence, Asriel's irises turn pink and the black face marking grows toward his eye, showing his increase in power from HATE's enhancements.
God of Hyperdeath
Upon the manifestation of Asriel's God of Hyperdeath form, large horns emerge from his head. Additionally, an appearance resembling that of Asriel's battle mode, consisting of black face markings, white irises, and black sclerae, become prominent. The Dreemurr's body also transforms to bear a purple and golden cloak, as well as forming the proportions of an adult-like body. By the way, he is spoken by Geritz as the adult voice.
