The Tenkai Kid

The Tenkai Kid (Japanese (Katakana): 新たな力、Xモード！) is the sixth episode of Tenkai Knights. It first aired on September 28, 2013 on Cartoon Network in the United States.

Plot
The boys asked Mr. White who manages the Earth side of the portal, and his intriguing thrift store, for some Quarton help, but he says he'll only help them if they agree to help him in the store.

Believing in Mr. White is giving them physical training, Guren embraces the workload. A skeptical Chooki later confronts Mr. White about his claims of whether or not he's actually been training them in anything other than housework. Mr. White pointed out that what form the training takes isn't as important as whether or not one believes in the training.

Later, on Quarton, Vilius again faces the Knights. Only now, Guren attempted to fight him with what he'd learned. When it appears Vilius was going to defat him, Guren felt despondent and was starting to believe that Mr. White was only using him before. But Chooki, as Lydendor, argued against that idea and tells Guren that he and Mr. White had been right all along. Suddenly, as Bravenwolf was about to be defeated. Thanks to Chooki's encouragement, Guren was able to unlock his Tenkai Titan mode for the first time. This shocked Vilius who then retreated and left everyone else on awe.
