Roy Alphard

Roy Alphard (ロイ・アルファルド) is a Sin Archbishop of the Witch Cult, representing the bizarre eating aspect of gluttony.

Appearance
Roy has long, disheveled dark brown hair, along with emerald green eyes that are yellow in the center and have a poisonous glimmer to them. He also has a young look, a mischievous smile, and wears a piece of cloth around his body.

Personality
Unlike Lye, Roy doesn't care about what he eats, nor does he place any special emphasis on who he eats with like Louis. As bizarre eating, his approach towards his meals is much more casual, emphasizing quantity over quality as seen when he ate Julius despite admitting he had a bland taste. As described by his brother, he simply wants to eat without any thought or preparation put into it, for which he was repeatedly criticized by his siblings. He isn't as close to Louis as Lye is, but is non the less devoted and caring towards her. He speaks in a collective manner using us and we instead of first or third person.

In combat, Roy strives to exploit his opponents' weaknesses, unlike his brother who likes to give his opponents a chance to compete with him. He views combat as nothing more than a violent way of getting his meals.

Abilities
Authority of Gluttony (暴食の権能 Bōshoku no Ken'nō): Roy is able to use the Authority of Gluttony.
 * Gluttony (暴食 Bōshoku)
 * Roy can eat the name and memories of their opponent. To eat a name, he touches them with his left hand, then licks the palm of the same hand. Things such as experience, talent, and the likes and dislikes of human relationships serve as food for him, allowing him to take advantage of any abilities or memories his opponents had. However, if he eats a fake name, he becomes plagued with severe nausea.
 * Those that have had their names eaten have their existences erased from the world, destroying any human relationships along with negating any contracts with Spirits.
 * Those that have their memories eaten become amnesic and any characteristics they may have had are reset, effectively making them into a different person.
 * Those that have both their name and memories eaten simply become a shell, and although they live, they no longer eat, excrete waste, or age, putting them in suspended animation.
 * Eclipse (蝕)
 * Eclipse is considered to be the trump card of gluttony. It is split into two types; Solar Eclipse (日食 Nisshoku) and Lunar Eclipse (月食 Gesshoku).
 * Lunar Eclipse allows the holder to use the victims' memories and harvest their skills and knowledge. Roy used Lunar Eclipse to boost his physical strength and speed in his fight against Julius Juukulius and Ricardo Welkin. It is worth noting that by eating a person's name and using Lunar Eclipse, Roy does not gain his victims' Divine Protections, Spirit Arts or Authorities.
 * Solar Eclipse, however, allows the holder to harvest his victims' name and transform their appearance accordingly. Louis, for example, transformed into Neiji Rockheart  and numerous other victims she and her two brothers had eaten throughout the years using her sibling's body.
 * Master Class Fighter: Through the accumulation of souls eaten, Roy gains any abilities his victims once had such as martial art techniques and magic. In turn, this has granted him extraordinary combat strength. He was able to overpower both Julius and Ricardo who are noted to be very strong.
 * Palm of the Fist King: A powerful strike that ruptures a person's internal organs, as well as outright, destroys physical objects like swords. It can also bypass mana based defensive techniques. The move originally belongs to Neiji Rockheart.
 * Snake of the Twin Sword: A sword technique that launches several combination slashes at high speed
 * Demon Beast Control
 * Because Lye, Roy and Louis possess the Witch Factors of Gluttony which were previously in Daphne's possession, they can direct Demon Beasts to attack certain areas. This is why the White Whale’s attacks were coordinated with those of the Witch Cult. In Arc 6, Lye and Roy are able to get to the Pleiades Watchtower in half a day by commanding the Demon Beasts in the Augria Sand Dunes, and order them to attack the Watchtower.
 * Equipment: Roy wields two claws from his hands that he uses with his speed and lightness. He also wields daggers that were hidden inside of his clothes.

Trivia

 * Roy's last name is a reference to the star Alphard, which is the brightest star in the Hydra Constellation.
 * The reason why he has the moniker "Bizarre-Eating" is that out of the three he has no standards when it comes to food.
 * Roy, similarly to Lye Batenkaitos dislikes using Solar Eclipse. According to him and his brother, it seems to make him experience the victims' thoughts which make him feel like he's being damaged. He describes this feeling as unbearable.
 * It is heavily hinted that Roy is working for Mother, being one of her "children", just like Elsa, Meili and Reisel
