Ninjago Jay is a very popular character in the Ninjago universe. He's the Ninja of Lightning and wears blue. (Blue Jay - get it?) Jay is one of the four Ninjas, one for each element, in a team put together by Spinjitzu master Sensei Wu.
Jay is a fun character who cracks lots of jokes and has some interesting hobbies when he gets some free time from training to be a Spinjitzu warrior.
