The Sons of the First Spinjitzu Master

The Sons of the First Spinjitzu Master are the offspring of the creator of Ninjago. The brothers, Wu and Garmadon, were a team whom defended Ninjago for centuries prior to the era of the ninja, and long before the First Serpentine War. Together, they fought many great evils of Ninjago's past, such as the Skulkin, the Serpentine, and the Time Twins.

Beginnings
After several millennia of protecting Ninjago, the First Spinjitzu Master eventually felt his time was nearing its end. Wanting to continue his legacy, he fathered two children: his firstborn, Garmadon, with power over Destruction, and Wu, his second-born, with power over Creation.
