Lucas has black hair of average length at the back, though at the front he has a long side fringe that covers a large portion of the right side of his face. He has large rimless glasses and dark gray eyes. He wears a yellow coat and blue jeans.


Lucas appears to be a quite shy but good-natured boy, even when confronted with unknown situations he doesn't seem to get fazed easily, and althought he was born a yo-kai, he enjoys living and being raised as a human.


Yo-kai Watch

Lucas makes his debut in the first game, he doesn't play much of a role until the last chapter "Farewell Yo-kai". After having a prophetic dream, he reveals to Nate/Katie that he's able to see yo-kai and holds the key that connects Springdale to the Yo-kai World. He is later revealed to be the son of King Enma.
