Leviathan  

Levi, レヴィ・ア・タン

Levi is a skilled member of the attack team sent by Xanxus to retrieve the Vongola Rings. He is known for his speed and loyalty to Xanxus. He carries eight parabolas on his back, which can discharge electricity simultaneously when used in his named attack "Levi Volta". Levi was chosen as the holder of the Ring of Thunder and faced Lambo in battle. Although he easily defeated the 5-year-old and 15-year-old versions of Lambo, he was outmatched by the 25-year-old version. However, just before delivering the final blow to the unconscious Lambo, Tsuna intervened, allowing Levi to win the right to the Ring of Thunder along with Xanxus winning the right to the Ring of the Sky. In Goetic scripture, Leviathan represents the sin of envy and is considered a demon.
