Aether is a delusional and overconfident version of the male Traveler, believing himself to be a legendary hero and irresistible ladies' man, despite repeatedly being defeated and outmatched, most notably by Arlecchino and Capitano, earning him the title of "Fraudeler". He flaunts his supposed victories and flirts with the women of Teyvat, often claiming romantic entanglements with various female characters, especially Raiden Ei,though his advances are usually met with indifference or pity.
