Tartaglia/Ajax/Childe

Tartaglia describes himself as "kind of a bad guy" who thrives on the thrill of fighting and causing chaos. As a child, he was scared and hesitant, but he secretly longed to join the mafia, inspired by the stories his father told him while they fished together. His personality changed dramatically after he accidentally fell off a cliff and met his master, Skirk, who trained him. Although he may seem friendly on the surface, Tartaglia is a bloodthirsty battle maniac. Skirk, his old master, instilled in him a sense of self-assurance, solipsism, and bravado, which allowed him to thrive on the sensations of life. As a warrior at heart, he is constantly seeking ways to grow stronger, no matter how he attains that power. Tartaglia considers those who want to be strong like him to be his friends, and he enjoys fighting them in battle. He craves combat and finds excitement in facing formidable opponents, even if it means risking his life. He uses guns because he is the least skilled with them, which makes his victories all the more exciting. He made it a point to conceal both his relationship with the Fatui and his status as an assassin.

Tartaglia's pride drives him to be extremely dependable when completing tasks, regardless of how difficult they may be or how much they conflict with his values. This trait, combined with his straightforward nature, makes him nearly impossible to manipulate. Although he dislikes the idea that his plan in Liyue Harbor could harm innocent people, he goes through with it to fulfill his mission in Liyue. However, he later discovers that he intended to fail as part of a much larger plan of which he was completely unaware, much to his dismay. Tartaglia stands out among the Harbingers because he prefers being in the spotlight, unlike his fellow Harbingers who favor clandestine operations and staying behind the scenes. He is a well-known public figure, frequently attending social gatherings and occasionally acting in plays and theater. As a result, his coworkers are often distrustful of him, while he despises their schemes and "intangible" methods. Although he is capable of scheming himself, he only resorts to such tactics when necessary due to his straightforward personality. Furthermore, he seems to treat his subordinates more leniently than the other Harbingers, claiming that he never uses lethal force against the recruits under his care or threatens any of them.

Tartaglia is fully committed to those he cares about. He is unwaveringly loyal to the Tsaritsa and holds her in high regard, viewing himself as her weapon of war. He also cares deeply for his family, frequently sending money, gifts, and letters home from the countryside. Tartaglia takes great pride in his three younger siblings, especially his youngest brother, Teucer, for whom he is willing to lie and even put himself in mortal danger to ensure his happiness. While he was once on good terms with Zhongli, allowing the former Police Chief to rely on him for financial support, Tartaglia has taken Zhongli's deception personally. He has stated that he will only forgive him if Zhongli agrees to a trial by combat. unbeknownst to Zhongli, who believes they can still meet for drinks to catch up after the recent events in Liyue, Tartaglia's feelings have significantly changed.

He wears red goggles pushed up on his forehead and has a beaded earring with a red crystal in his left ear.
