Xiao is a yaksha who has fought in the Archon War and holds a high level of seniority among adepti. He has a reserved demeanor and has little intention of getting close to mortals. He does not want sympathy for his past and believes his fellow Yakshas would also find it insulting.[2] Accordingly, Scaramouche treats most people, especially regular humans, with contempt. While Scaramouche was one of the Harbingers, he would frequently abuse his Fatui subordinates, and he's a puppet.
