Cruel Lord
From Brickipedia, the LEGO Wiki
The Cruel Lord (voiced by Michael Adamthwaite) is a villain who, with a force of guards, oppressed a farming community in Ninjago as seen in The Mask of Deception and School for Crooks. The lord wears a gold breastplate and darker gold pants, an Asian-style helmet, a white shirt, black gloves, and boots. His reign was overthrown when Nya appeared to confront him, having infiltrated his domain disguised as a water carrier.
