Dagon

An unregistered special grade cursed spirit born from the fear of the sea, Dagon began collaborating with Fake Geto after Yuuji Itadori's death. It has the appearance of an octopus with two muscular arms and wears a cloth over its head. It often cries "bufuu" and rarely speaks. Despite being timid, it is caring towards its companions. Dagon, a master of a technique that generates and manipulates water, can use a vast amount of water to overwhelm and submerge opponents, and also as a defensive barrier. It possesses high physical endurance, resistant to ordinary attacks. After gaining wings, it also became capable of staying airborne. During its cursed womb phase, it devoured a large number of humans. It has a domain called "Tou'un Heisen," which, when activated, unfolds into a beach-like scene where it can endlessly summon a fierce fish shikigami called "Shiruru Yuugun." Initially encountered by Fake Geto in its cursed womb form, Dagon transformed during the Shibuya Incident into a large humanoid with red skin, tentacle-like barbels, and bat-like wings. After the transformation, it became braver and started speaking fluently. Dagon insists on being called by its name, disliking being simply referred to as a "cursed spirit." In this form, it fought against Naobito, Nanami, and Maki, but was put at a disadvantage with the arrival of Megumi Fushiguro and subsequently killed by an attack from Toji Fushiguro. Dagon's name and appearance are inspired by Cthulhu.
