The Cartoon Network Wiki

ThunderCats Roar is an American animated television series. The series premiered in the United States on the Cartoon Network app on January 10, 2020 as a sneak peek. The series officially debuted in the United States on Cartoon Network on February 22, 2020.


Staying true to the premise of the original series: Lion-O and the ThunderCats — Tygra, Panthro, Cheetara, Wilykat and Wilykit — barely escape the sudden destruction of their home world, Thundera, only to crash land on the mysterious and exotic planet of Third Earth. Lion-O, the newly appointed Lord of the ThunderCats, attempts to lead the team as they make this planet their new home. A bizarre host of creatures and villains stand in their way, including the evil Mumm-Ra, Third Earth’s wicked ruler who will let nothing, including the ThunderCats, stop his tyrannical reign over the planet.


After the series was first revealed in a trailer on May 2018, it was met with immediate backlash. The trailer has been hated by many fans of both the original series and the 2011 reboot (which it also has drew comparisons).

The series has been criticized for its art style, characters' utter stupidity, villains' extremely-creepy designs and comedic tone, the reveal had also sparked debate on the comedic tone and animation style of many reboots and shows airing during the time, such as Teen Titans Go! and OK K.O.! Let's Be Heroes.

In spite of the general dislike of the show, some of the episodes during its run were seen as "okay or average" by some viewers after its premiere.
