Vivi appears at first to be gullible, clumsy, and shy, often stumbling over his speech and lacking self-confidence. He is fearful of his powers, origins, and his own lifespan. Over time, he gains bravery and confidence, as well as a sense of right and wrong. Vivi befriends Zidane, who acts like an older brother to him, and resolves to use his magic to protect his new friends. At the start of the game he's been referred as "Pointy-Hat Boy" and a "slave" that Rat Kid (Puck) calls him.
