Lion-O and Tygra's rivalry over the crown and Cheetara's affections are a continuing subplot through these eight episodes.
The update takes the characters of the original series and melds them into a fantasy-style hero's journey.
Producer Ethan Spaulding worked on “Avatar: The Last Airbender,” and you can see influences from that program on this one.
By episode 14, “New Alliances,” the Thundercats have gone on the offensive against Mumm-Ra's army.
Lion-O wants to turn the lizards against their master, but Mumm-Ra retaliates by bringing in two even more vicious generals, Addicus and Kaynar, updates of Monkian and Jackalman from the original series.
Book Two ends with the two-part “Trials of Lion-O,” another concept borrowed from the original series, but with a new twist, as Lion-O must prove his skills and heart to regain a chance at life.
