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.
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 likes to exert his authority over others, nearly snapping with anger and berating one of his subordinates when they suggested another plan instead of following his orders.
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 dark navy blue hair that covers his ears and dark blue-lit eyes with bold red eyeliner.
His attire is 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.
