King Andrias Leviathan

King Andrias Leviathan is the main antagonist of Amphibia starting from "True Colors". He is the original monarch of Amphibia,[4] who lives in the Newtopia Castle in Newtopia. Hailing from a lineage of conquerors, Andrias sought to use the Calamity Box to conquer other worlds just as his ancestors did long ago. To accomplish this, Andrias took up the appearance of a benevolent ruler and ally to the human girl, Anne Boonchuy, to get the music box, only to drop the façade once he got the box and initiate plans to invade Earth as his first world conquest. Meanwhile, Andrias concentrates his invasion efforts on Los Angeles, as well as the destruction of Anne, who became a major obstacle to his goals.
