Leviathan, commonly shorted to "Levi" is a loyal subordinate to Xanxus and thus only fights for his approval.

He also seems to be zealous when it comes to fighting, he turned out almost 2 hours early for the Vongola Inheritance fight. His speed in completing objectives is second to none and is the fastest in the Varia.
