Teucer

Teucer is a character in Genshin Impact, a young boy from Snezhnaya and the younger brother of Tartaglia (Childe). He also has two older siblings, Tonia and Anthon. Teucer first appears in Tartaglia's Story Quest, 'Monoceros Caeli Chapter: Act I - Mighty Cyclops' Adventure!'. Having learned of the Traveler through Tartaglia's letters and feeling lonely without him, he travels alone from Snezhnaya to Liyue to find him. In Liyue, Teucer wanders into Lingju Pass, where he encounters a large "Mr. Cyclops" (Ruin Guard), and is later rescued by the Traveler. After being taken to Northland Bank, he reunites with his brother. To hide his connection to the Fatui, Tartaglia asks the Traveler to help babysit Teucer. Later, Teucer visits the Toy Research Institute in Liyue (actually an abandoned facility) and returns to Snezhnaya by boat after his visit. Teucer has distinctive features, with pale, freckled skin, blue eyes, and orange hair, much like his older brother Tartaglia, and wears a distinctive brown and white Snezhnayan bomber hat.
