There have been talks about a new Thundercats show for a while but two days ago and official image of the new characters was released.

I could explain the show but the pres released has it all perfectly explained

Roaring to life through WBA and Studio4°C’s use of the Japanese animated artistry of anime, “ThunderCats” characters Lion-O, Mumm-Ra, Panthro, Cheetara and others will spring off the screen with realistic cat-like characteristics inconceivable in previous incarnations.

The new “ThunderCats” will appeal to viewers who have loved the characters all their lives as well as young newcomers to the franchise. A sweeping tale combining swords and science and boasting ferocious battles with the highest of stakes, the grand origin story of Prince Lion-O’s ascension to the throne – and of those who would thwart his destiny at any cost – takes on epic dimensions in this sharp new telling. As the forces of good and evil battle each other in the quest for the fabled Stones of Power, Lion-O and his champions learn valuable lessons of loyalty, honor and mortality in every episode.

The shows producers are Michael Jelenic (“Batman: The Brave and the Bold,” “Wonder Woman”) and Ethan Spaulding (“Avatar: The Last Airbender”) with the xecutive producer chair being held by Sam Register (“Teen Titans,” “Ben 10,” “Batman: The Brave and the Bold”).  With such an experienced cast the show will prove to be a hit!
