In this state, in contrast to his child form, Asriel has black sclerae with white slit pupils, longer fangs, a pair of horns, and black markings on the sides of his face. He wears a long robe with white sleeves and the Delta Rune symbol, akin to Toriel's robe, as well as a large collar with shoulder pads. He also wears a locket similar to the Heart Locket. Asriel's attacks consists of a variety of rainbow and star-shaped attacks. It includes fire, diamond bullets, rainbow-colored straight beams and lightning, and blade swipes. In his final form, his attacks are a mix of rainbow-colored comets and a powerful beam.
