Gowther³

10 years ago, it was unknown exactly what Gowther looked like, this is because he always wore his armor. This armor made people think he was quite a large person. This armor is a full body armor made of silver, the helmet has a pair of horns, but one is broken.

Without armor, Gowther is shown to have amber eyes and dark red (sometimes depicted as magenta) hair that reaches down to below his head. His usual attire consists of a grey, long-sleeved striped shirt underneath a white sleeveless top, as well as a pair of black pants and short boots. Gowther also wears a pair of glasses with light frames and is seemingly unable to see without them. After the events of the Kingdom Infiltration Arc, Gowther has changed his manner of dress, now wearing a sleek white outfit, consisting of a white shirt with a white cape with decorated edges and black pants. He has his trademark symbol, the goat, on his right pectoral muscle.

He has a very feminine face, and as such, he can be mistaken for a girl. This is because he was created in the image and likeness of the woman his creator loved, but he gave him the body of a man so that he would not feel any kind of attraction to him.

Like many characters, Gowther has the ability to transform, however his ability seems to be limited to changing his skin color and the length and color of his hair. In the manga, he uses this ability to change his appearance and calls himself Armando, all in order to please Pelliot. When using this transformation, his hair simply grew and resembled the hair of Pelliot's mother.

In the anime, however, he shows a different transformation called Alan in order to travel with Dale. With this transformation he simply showed shorter, green hair.

In its original form, it has been shown to be a small doll.

During the battle between Dale and Dawn Roar, Gowther reveals himself to be the true sin of lust, speaking in a distinctive, emotionless manner. His expression never changes, being perpetually blank and, in the manga, his speech bubbles are distinctively square, compared to everyone else's round bubbles. Despite his emotionless nature, Gowther cares for others, as shown when he protects Pelliot from an attack by Dale.

He is shown to be very clueless and unaware of others' feelings, failing to understand the meaning of friendship. He often states things objectively, not understanding how what he says can affect people. He decides to help Elizabeth Liones on her journey not out of a desire for justice, but because he felt obligated as a member of the Seven Deadly Sins. Gowther does not understand emotions, so he constantly tries to understand them, for example observing Meliodas and Ban's friendship or the feelings of love between Diane and King. This desire has even led him to use his powers to do "experiments" by manipulating the memories of others, such as altering Guila's memories to try and understand love.

However, despite his title as the Sin of Lust, Gowther has yet to show any signs of lust. He does, however, show a cold and rather cruel side when using his Nightmare Teller technique on another person, pointing out how fragile humans are when faced with their deepest fears. Despite Gowther's emotionless nature, he seems to enjoy posing whenever he's presenting himself or on a mission, it's possible he got this habit from Pelliot.
