Tartaglia describes himself as "kind of a bad guy", living for the thrill of a fight and causing chaos as a child, Tartaglia was frightened and hesitant, but he secretly desired to become an adventurer like the ones his father told him about as they fished together. 

After falling into The Abyss and meeting and training with Skirk, Tartaglia's personality drastically changed. Although he appears to be relatively friendly on the surface, Tartaglia is a bloodthirsty warrior. The Abyss and his old master, Skirk, made him self-confident, solipsistic, and brash, thriving on the sensation of being alive. A warrior at heart, he constantly seeks ways to grow stronger, regardless of how he obtains said power. Tartaglia considers those who wish to become strong like him to be friends and takes pleasure in battling them on the battlefield. He lusts for combat and grows excited by fighting strong opponents, even if it could mean dying in the process. He uses bows because he is weakest with them, making his victories with them all the more exhilarating.
