Arkayna, Zarya, Emerald, and Piper--unexpected heroes who together become epic warriors--are drawn together by a prophecy to battle evil.

In an effort to get Em out of the house, the Mysticons go to the mall, where Em is swept up in the world of a Battle-Bots style competition, ''Machinations.'' When she and Piper team up and enter the competition, they not only find themselves battling with robots, but against new friends with scorned feelings.

Tied to Mysticons, a cartoon series on Nickelodeon!
