He is known simply as Pride the arrogant a well earned tittle and the most revered of all the homunculus. Even his own 'brother' Greed refused to recognize him as nothing more than a monster. He is menacing aura to himself that is extremely disturbing for a person of his age(although he is close to four hundred years old but only appears as a young boy)
Like his name suggests Pride is extremely arrogant, confident in his own abilities. He often fails to see the strength in others especially humans. He lacks empathy towards others and was shown to devour his own 'brother' Gluttony when the battle wasn't going his own way, claiming that it wasn't a true act of cannibalism since they had all once been a single being within father.
Pride's powers allow him to shape and meld the shadows around him, as they are an extension of his true form which resembles a black void with multiple eyes and teeth. He can shape the edges of these shadows to the point where they can clean cut metal or strangle a person to death. He's also able to form the teeth in his shadows to the edge, so he can ''cut'' through almost anything. He's even able to cut through multiple fullgrown trees with ease. When he devoured Gluttony's philosopher's stone into himself he gained his ability to track others from their scent.
