Dareth

Dareth is a martial arts master who runs a small dojo and refers to himself as “Grand Master Dareth.” The ninja met him when they were looking for someone to train Lloyd Garmadon. He has no special powers and is much better at talking than taking effective action. It was only later, when he played a vital role in stopping the Stone Army, that the ninja accepted him as one of their own and he got the title: Brown Ninja. Dareth is a "master" of all animal fighting styles. According to him, he is the Master of Disguise, with the ability to create fake identities. He helped Nya to look like a Kabuki dancer, so she could wander unnoticed into Chen's Palace.
