Tartaglia, also known as Childe, is a playable character in Genshin Impact and one of the Eleven Fatui Harbingers, serving as the Eleventh Harbinger. He is a skilled combatant who enjoys battle and seeks strong opponents, while also showing a more playful and affectionate side in his personal life. In the story, he plays a major antagonist role during the Liyue Archon Quest, where his actions drive a key conflict, but he is not purely villainous and remains a complex, morally ambiguous figure.
