Story
Eons ago, a cube–like peaceful planet named Quarton is populated by the Tenkai, robots who could shape–shift into living bricks. Quarton was ravaged by a war between two opposite factions: the Corekai Soldiers, led by the valiant and fearless Commander Beagle ("Beag"); and the Corrupted Army, led by the ruthless Lord Vilius, who desired to obtain the source of Tenkai energy for his own purposes. However, the only ones who were strong enough to defeat him were the 4 Legendary Tenkai Knights of Quarton: Bravenwolf, Tributon, Valorn, and Lydendor. Facing defeat, Vilius unleashed the mighty Tenkai Dragon, who was later defeated by the 4 Knights where its fragments scattered across the planet. These heroes were never seen again. One year later, Lord Vilius and the infamous Corrupted Army have returned, more powerful than ever before.

Now on planet Earth in the year 2034 within Benham City, four young teenage boys, named Guren Nash, Ceylan Jones, Toxsa Dalton, and Chooki Mason, find an interdimensional portal to Quarton where they are chosen by Boreas of the Guardians to become the new generation of Tenkai Knights and prevent Lord Vilius and his Corrupted Army empire from taking control of both worlds.
