Barbatos

"'The impeccable butler who follows Diavolo around as if he were his shadow. His ability is to see both the past and the future.'"

Barbatos is Diavolo's loyal servant. He is first introduced in Lesson 2-13 along with Simeon and Luke.

Appearance
Barbatos has short dark green hair with bangs reaching his eyebrows. The fringe on his left is longer, reaching his nose and has a turquoise ombre. Like all the other demons, Barbatos has painted fingernails. Barbatos's nails are a mauve purple color.

Personality
Barbatos has a very calm demeanor, although he does enjoy lightly teasing other people. He is nice towards MC and often saves leftover sweets he bakes for them. He is very loyal to Lord Diavolo, and wishes to serve him well. Diavolo has complained that sometimes Barbatos is too harsh on him. The demon brothers describe him as overprotective of Diavolo.

He also shows extreme patience for Diavolo, as evidenced in The Fantastic Three(3) chatroom interactions. He is usually calm and collected and agrees with almost everything Diavolo says. He never displays much emotion and often comes across as sarcastic.

Barbatos is also relatively friendly towards Luke, teaching him how to make pastries as seen in chatrooms, and they often bake treats together. On many occasions, Barbatos gives Luke advice for cooking, such as recommending him better baking powder brands. According to Luke, Barbatos is the greatest pastry chef in all of the three worlds (Devildom, Celestial Realm, Human World).

It seems Barbatos and Lucifer have mutual respect for one another, although Barbatos occasionally jokes about Lucifer. In some instances, he is shown being concerned over Lucifer's well-being. When Diavolo requested that Lucifer doesn't work himself too hard, Barbatos agrees with Diavolo's statement and presents an image MC took of Lucifer, overworked, to help Diavolo persuade Lucifer to get some sleep.

Barbatos takes his position as a butler very seriously. He even teaches the demon brothers intricacies about his job in the Demon De Butler event. The demon brothers believe that Barbatos could do anything, thus resulting in them frequently seeking out his help.

While typically exuding a calm demeaner, Barbatos seems impartial to being interrupted when speaking about something he is passionate about, even going so far as to throw a fork at Mammon's head for speaking over him. According to Little D. No. 2, Barbatos's smile remains in place even when he is angry. Some of the demon brothers — Mammon in particular — think that Barbatos is shady and scary, and are convinced he has a hidden room in the Demon Lord's Castle where he partakes in the act of torturing people.

Background
Barbatos mentions in the chat That's What I Mean that he was never a child. He has the power to see the past and the future, and is able to choose from multiple realities whichever one he prefers to become the sole reality. He can accomplish these feats by opening doorways to any time and place, including the Human World and the Celestial Realm. Lord Diavolo expressly forbids him from using his power freely.

He admits to MC in The Legendary Dame Devilgram that he was once a Dame at Queen Rose's banquet. He was considered so beautiful that it caused an uproar, and piles of fan mail was delivered daily to the Demon Lord's Castle. From then onwards, he swore to never be a Dame again.
