His personality is quite arrogant. He is cold and prickly, to the point where his words and actions have a sharp edge. He shows near-contempt when looking at people he dislikes. He has a tsundere-like temperament. However, there is a reason for this personality. It lies in his past. The Wanderer was created in the past by Raiden Ei, the Archon of Inazuma and the God of Eternity. Soon after, he was discarded for being "weak." The people of Tatarasuna found the abandoned Wanderer and lived with him. At that time, he was a pure and kind-hearted being known as the Kabukimono. That was until tragedy struck. A man from Fontaine seemed to be getting along well in Tatarasuna, but he was secretly plotting behind everyone's back. The man from Fontaine was actually Dottore, the second of the Fatui Harbingers. Dottore plotted to bring the Kabukimono into the Fatui. He murdered Niwa, the Kabukimono's closest friend, and deceived him by saying Niwa had committed a crime and fled. The Kabukimono fell for the lie. He then disappeared from Tatarasuna. While wandering after leaving Tatarasuna, he met a young boy and lived with him. However, that boy soon fell ill and died. Afterward, the Kabukimono instigated the Raiden Gokaden, joined the Fatui, and became the sixth of the Harbingers under the name Scaramouche. He was subjected to experiments as Dottore's test subject, and after plotting to become a god in Sumeru, he was eventually subdued by the Traveler and had his Gnosis taken away. Following that, he erased his own information from Irminsul and eventually came to live as the Wanderer. The Wanderer likes bitter things, especially bitter tea, and dislikes sweet foods. His age is approximately 500 years. However, his mental age is around his teens to early twenties, an unstable stage of life. His appearance is that of a permanent late-teenager. He is male and a puppet. His height is estimated to be around 163cm. He has cat-like features.
