The King is a playable character in LEGO Worlds.
The King wears a golden crown atop his white bearded face. His torso is blue with ermine lining and a gold chain bearing a golden crown on his chest. His arms, hips and legs are blue to match, and his hands are the regular LEGO yellow.
The King has no unique idle animations.
There are many kings in the LEGO universe, but this Character doesn't resemble any of them, and thus, is probably a unique character for this setting.
