Morpheus

•Morphium Coma: Morpheus manifests white poppies around the bodies of his victims. Each poppy that changes color is an emotion he steals from his enemies; they end up being gradually deprived of anger, sadness, the will to fight, and so on until they have no emotions left.

Morpheus is sent with his three brothers to find Tenma of Pegasus, with orders to imprison his body and soul in Morphia, a place in the Dream World where the souls of heroes and kings are imprisoned. After achieving this without the slightest difficulty, Morpheus confines Tenma to a dream where Hades and Athena are still children, and where the Sacred Wars do not exist, making Tenma believe that everything that has happened so far has only been a dream. But Athena tries to rescue Tenma, taking control of her "young self" in the dream, and guiding him to an image of Sisyphus of Sagittarius, thus awakening Tenma of Pegasus's memory before being expelled from the dream by Morpheus, causing the Saint to awaken from the false reality. Freeing himself from Morpheus's power, Tenma attacks the god with his Meteor Fist of Pegasus technique, but Morpheus is unaffected, trapping Tenma in a net of Underworld Poppies, so that they absorb all his feelings and emotions until he is left an empty shell. But then, moved only by sheer willpower, Tenma frees himself, and Pegasus transforms into Divine Armor, then delivers a single blow that ends Morpheus, who realizes before dying that Tenma had a vision in which Hades seemed to be the one who made him wake up from the effect of the poppies. Later, his soul would be summoned by his brother Oneiros to form a monstrous creature, but it is destroyed by the Golden Arrow of Sagittarius, imbued with Athena's Cosmos, and split into four by El Cid to attack the four souls at once.

Morpheus shares with his brothers an arrogant nature, and tends to underestimate opponents because he doubts human capacity, and maintains the superiority of the gods.
