ThunderCats is an American/Japanese animated television series, produced by Ethan Spaulding and Michael Jelenic. A reboot of the original 1980s TV series of the same name, ThunderCats was developed by Warner Bros. Animation and Studio 4°C, and combined elements of western animation, with Japanese anime. The series began with an hour-long premiere on Cartoon Network on July 29, 2011.
Following the destruction of their home, the kingdom of Thundera, the ThunderCats are forced to roam the planet Third Earth, in order to find a way to defeat the evil sorcerer Mumm-Ra, who plans on taking over the universe. Story-wise the series attempts to take a much darker and more cinematic approach than the original show, featuring a lot more focus on characterization and more sophisticated themes.
Initially planned for 52 episodes, it was confirmed by ThunderCats art-director Dan Norton in early 2013 that the show had been canceled after only one season. Reruns of the show later aired on Adult Swim's Toonami block.Overview from themoviedb.org
