Scaramouche is first encountered as the main antagonist of the Unreconciled Stars event.
Scaramouche first appears as "???" during the event quest "The Crisis Deepens," where he introduces himself as a "vagrant from Inazuma." While he appears to be friendly at first, he learns of the Traveler's identity as the Honorary Knight and tries to strike them down, only to be stopped by Mona, who senses his intents.
It is later revealed that he traveled to Liyue to investigate mysterious meteorites and enters a dream, where he realizes that the stars and sky are a "lie", and that "Joker" had intentionally sent him without forewarning what would happen. After leaving a promising threat against the Traveler, he takes his leave to confront the senior Harbinger.
He later heads to Inazuma to oversee the creation of Delusions at a secret facility and confronts the Traveler. Rather than facing them head on, he incites them into succumbing to the old gods' wrath, but the plan is partially foiled when Yae Miko walks in. She then negotiates for their safety by offering Beelzebul's Gnosis, which he accepts and allows her to leave with them.
According to rumors heard by Viktor, Scaramouche is not well-liked. Some say he has a disagreeable personality, being difficult to get along with, while others say he doesn't know when to keep his mouth shut. Even his fellow Harbingers appear to dislike him. Presumably like the other Harbingers outside of Childe, Scaramouche tends to have an air of authority and arrogance to him, as he frequently insults others on a whim.
As a Harbinger, Scaramouche is naturally a cunning individual. With the brains and tremendous power to back him up, he is an unpredictable person. Scaramouche is two-faced, first debuting in a friendly manner with the Traveler in order to lower their guard so he could kill them.
Scaramouche is described as a man with a slender figure and a handsome face. He has a youthful appearance, short in height with indigo hair that covers his ears, as well as indigo eyes with bold red eyeliner.
His attire consists of black shorts and black sandals, and a large hat with four upwards-curving hooks along the circumference, and what seems to be his mask on the center. Two ornamental accessories hang from red threads attached to the back of his hat. At the back of his hat hangs a translucent black veil separated into two, with ombre brown swirls near the bottom. His overall attire resembles traditional Japanese or Chinese wear.
Scaramouche was originally created by Beelzebul as a test into the technology of making puppet bodies. He was not meant to resemble her, only to test if creating a puppet body was possible. As his creation was successful, he was considered the prototype for the puppet she now uses as the Raiden Shogun. She did not wish to kill him, so she instead sealed his power as a divine creation then released him into the wild, where he wandered across Inazuma. He eventually encountered the Fatui and joined their ranks, wherein they unlocked the innate power he had as a creation of an Archon. The Fatui also gave him some additional modifications, and eventually, he climbed to the position of The Balladeer, the Sixth of the Eleven Fatui Harbingers.
- Scaramouche is derived from a stock character in commedia dell'arte, a type of Italian theatre.
- Scaramouche ("Little Skirmisher") is usually an assortment of different villainous traits, but is primarily unscrupulous and unreliable with a penchant for intrigue, which lands him into difficult situations.
- Scaramouche was constantly being cudgeled by Harlequin, which may explain why his name is based on an Italian word meaning "skirmish," or "a minor fight." While there is no Harbinger known as the Harlequin, it is possible that this is a reference to Pierro, also known as the Jester or Fool. This may also explain Scaramouche's mention of the Jester, "What was the Jester thinking? He must have had some inkling of what we might discover on this mission... Would it really have been so difficult to give me a little forewarning? Hmph, or maybe he just wanted to give me a fright...," suggesting that Pierro sent him on a mission as a way to belittle him.
- Unlike his fellow Harbingers, Scaramouche does not wear a mask on his face, but on the top of his hat. This could relate to the original commedia dell'arte actor Tiberio Fiorillo, the role for Scaramouche, who played without a mask.
- Scaramouche's stylized kasa hat may be a reference to the character's costume; it consisted of a large loose hat that hung down over his neck.
- The term scaramouche has become associated with a class of puppets with extendable necks, which may be attributed to the fact that Scaramouche was originally a prototype for the Raiden Shogun's puppet.
- His real name Kunikuzushi (Japanese: 国崩) literally means the "Country Destroyer" in Japanese.[Note 1]
- It is a name given to breech-loading swivel guns imported from then Portuguese Goa (now a part of India) and used by the samurai lord Ootomo Sourin during the Sengoku period. The Raiden Shogun's calling her first prototype "Kunikuzushi" can be interpreted as she was planning on making war machines against the enemies.
- The word can also refer to a villainous stock character in kabuki, a traditional form of Japanese popular drama. Kunikuzushi typically appears in works whose theme is O-Ie Soudou (noble family disputes) and plots to usurp a country. Kunikuzushi is considered to be one of the most heinous yet energetic and prominent stock characters in kabuki, and its importance usually demands the role to be played by the head or the star of a kabuki troupe. These traits of Kunikuzushi in kabuki are fitting for the history and personality of Scaramouche in the game.
- Various aspects of Scaramouche's character reference the lyrics of the song "Bohemian Rhapsody" by British rock band, Queen.
- The soundtrack that plays during Scaramouche's first appearance in the event, Unreconciled Stars, is named "Ominous Fandango", a reference to the lyric: "Scaramouche, Scaramouche, will you do the fandango?"
- The lyrics mention "Beelzebub," an alternative form of Beelzebul, who is Scaramouche's creator. The song's speaker addresses his "mama" several times which may be an interpretation of the type of bond between Beelzebul and Scaramouche.
- The lyrics "thunderbolts and lightning" may be a vague reference to Inazuma or Electro in general.
- The lyrics "Is this the real life? Is this just fantasy?" show the song's speaker having doubts about the natural order of the world, similar to how Scaramouche states, "The stars, the sky... It's all a gigantic hoax. A lie," in the quest Where Ancient Stars Align. The song also references "Galileo" who was known for challenging beliefs about the astronomical model during his time.
- For players who may have missed the Unreconciled Stars Event during Version 1.1, there is alternate text for your encounter with him in the Delusion Factory wherein he introduces himself to the Traveler.
- Erroneously, he only ever refers to himself as The Balladeer, however, later on, Paimon refers to him as Scaramouche, even though he only ever introduced himself with his alias.
- In Mandarin, the word 国崩 (guóbēng) unambiguously means the collapse of a country. This contrasts with the Japanese usage of Han characters whereby 国崩 has two equally possible ways for interpretation, namely, the collapse of a country (Japanese: 国崩れ kuni kuzure) and the destroyer of (or the act of destroying) a country (Japanese: 国崩し kuni kuzushi). Historical cannons, traditional stock characters, and the English name of the in-game character follow the latter reading.
