Before we start...

Over a hundred years have passed since the time of Lloyd Garmadon. And since then, the elemental masters deemed Ninjago too small for them. They've moved into the world where the main sport is where metal contraptions called beys collide in stadiums.

The next Master of Lightning is Valt Aoi, but the thing is, he doesn't even know he has the Elemental Power. It has lied dormant in him for years. However, he's about to find out about his heritage. In a way no one saw coming...

And when he does, a new generation of Elemental Masters will rise.
