Dr. Julien

"You were built to protect those who cannot protect themselves." - Dr. Julien.

Dr. Julien was an inventor who created Zane, the Falcon, and the Bronze Robot.

History
Dr. Julien created Zane and his pet Falcon. As time passed, he taught Zane how to walk as well as other basic human activities such as cooking and housekeeping.

On his death bed, Dr. Julien told Zane "the only reason I'm about to do this is because I love you" before turning off his memory switch.

Later, in the Season 1 episode Tick Tock, Zane finds out he is a nindroid and turns on his memory switch. It appears that he created Zane because he did not have a family of his own, and grew to love him as a son. Knowing this made Zane feel stronger, which helped him unlock his true potential.

Trivia

 * He has the same hairstyle as Ed; the hairstyle is common in Ninjago.
 * He created the Bronze Robot to protect the workshop, though in the episode Tick Tock, Zane destroys it.
