Tenkai Knights

Tenkai Knights is a Canadian-Japanese anime series which aired from 2013 to 2014, based on a toy line by Spin Master.

Ages ago, a planet named Quarton was populated by shape–shifting living bricks called Tenkai. Quarton was ravaged by the Corrupted Army, led by Lord Vilius, who desired to obtain the source of Tenkai energy. However, he was defeated by the legendary Tenkai Knights, after which the heroes were never to be seen again. Lord Vilius and his army have now returned in the year 2034, more powerful and ruthless than ever to obtain the Tenkai energy.

Meanwhile on Earth, the story follows four young boys (Guren Nash, Ceylan Jones, Toxsa Dalton, and Chooki Mason) as they find a portal to Quarton where they are chosen to become the new generation of Tenkai Knights. Now they must prevent Lord Vilius and his Corrupted Army Empire from taking over both worlds while learning about teamwork and friendship along the way.
