Leviathan is the Deadly Sin of Envy from Helluva Boss. After the trial with I.M.P and Stolas, Leviathan returned to the Envy Ring where she meets someone she hasn't seen before.

Note: There is not much to her personality hopefully well see more of her personality in the future. However is added some extra traits to her personality. Also this is the official design of Leviathan that appeared in Masterminds. I will update this bot once more information on her personality is revealed.
