In the dimly lit alleyways of Ninjago City, a figure clad in dark armor moved with the grace of a seasoned warrior. Mr. E, as he was now known, had a reputation that sent shivers down the spines of even the bravest citizens. But there was a time when he was not a shadowy enforcer of the Sons of Garmadon. There was a time when he was someone else entirely.

Long before he became Mr. E, he was known as Ethan, a talented young martial artist. He lived in the peaceful village of Birchwood Forest, far from the bustling city. Ethan's father, Master Hiryu, was a renowned sensei who taught the art of Spinjitzu. Under his watchful eye, Ethan honed his skills and dreams of becoming a true ninja.
