The lost prince of the Underground, son of Asgore and Toriel. After his tragic death for Chara and transformation into a soulless and uncaring flower, he is reawakened after obtaining all the souls of the Underground, including the human souls. Normally, he’s very kind and loving, but he’s back to destroy the universe. Only our protagonist can stop him, and they’re carrying all of monsterkind’s hopes and dreams with them. (Asriel has two forms: him as a kid and him as the “God of Hyperdeath” as he calls himself. If you think he should have two different voices for them, do it! If not, don’t! Up to you. Make sure to record at least two or three takes of each line.)
