Surya has light pink hair, part of which is held in a high ponytail. He has lightly tanned skin. He wears silver armor, a white cape, and black gloves with what appears to be silver rings on each of his fingers. In the Nastika v. Astika scene, he wields a sword while facing Asura (light v. dark).
Nothing is known about Surya's personality at this time. He seems to be a kind god, as he was friends with God Kubera and was worried about him. He was also shown smiling at Saha On when giving him an oracle.
(6) During Asha's trial, Saha On reveals that he received an oracle from Surya during the Cataclysm in N0. He allegedly told Saha that his friend Kubera was in danger of disappearing and that he was worried about him.
