Hades God Dagon is the leader of the Infershian Pantheon and a major antagonist in Mahou Sentai Magiranger.
After N Ma was destroyed by Isamu's sacrifice, it activated a fail safe in the awakening of the Infershian Pantheon. Once revived, with Vancuria as a witness, Dagon and the other Hades Gods rose from the Earth and he introduced them, saying they were the humans’ punishers and have surfaced to tell humans to wallow in despair for the judgment they will execute. As Hikaru explained to the Ozu siblings, the Infershian gods' punishment on the surface can not be interfered as the act would jeaopardize Magitopia while ensuring the return of N-Ma in his full glory.
But as the Magirangers battle the gods chosen to deliver judgement, Dagon realizes that there is no sign of N Ma’s return and learns that his master's soul was sealed within the body of Isamu as Wolzard. Resolving to deal with Wolzard, acting against their laws with Sphinx's disapproval, Dagon arranged for Slepnir to aid Drake in fighting the Magirangers together to lure Wolzard into the open so Vancuria can place one of Dagon's scales on the dark knight. From there, with Wyvern and Titan accompanying him, Dagon finds Wolzard and defeats him while taking N-Ma's soul. When Titan attempts to enter a deep sleep after being chosen to be N-Ma's vessel, Dagon murdered him to ensure his master's rebirth.
After he and Slepnir execute Sphinx for her refusal to carry out her judgment as ordered by N Ma, Dagon leads the attack on the surface and destroys Smoky before draging Miyuki Ozu into Infershia to show her the futility of fighting the darkness. However, Dagon was confronted by Sphinx who was revived by Vancuria. Though Sphinx tries to convince him that N Ma caused too much death, Dagon refused to forsake their leader as he dies fighting.
