Jealousy often leads friends to drift apart. That's the central theme of this episode of Freedom Force on Tarzan & The Super 7.
Toshi (Brian Tochi) befriends another youth, Kyoto, who challenges him to various competitions. Frustrated at being defeated, Kyoto makes a deal with a demonic spirit seeking revenge on Kyoto's dad to become the Scarlet Samurai (who sounds like an uncredited Ted Cassidy) in opposition to Toshi's alter-ego, the Super Samurai. It may take the rest of the Force to turn the tide.

I guess writer Gerry Boudreau must've seen "War of the Gargantuas" a few times. A film like that springs to mind, not only because it was a Japanese film, but because of the two Japanese youth in the story.
