Watch ThunderCats (2011)

Thundercats tells the story of a group of human-like cats, and their struggle against the evil Mumm-Raa, and his army of mutants, in this re-incarnation of the classic 1980's cartoon series. The series was created by Ethan Spaulding and Michael Jelenic as a fusion between American and Japanese animation styles.

The story comes across darker with new twists on the original storyline. This time around, the main character, Lion-O, a prince of the Kingdom of Thundera, leads a mismatched, yet resourceful band of cats to flee, after the city is overtaken by the lizard army led by Mumm-Raa and his generals, Slithe, a lizard, and Grune, a cat and traitor-general to Thundera. Lion-O takes his birthright, the legendary Sword of Omens, and his fellow Thundercats, on a journey across Third Earth, encountering a host of friends and enemies in search of a way to defeat Mumm-Raa.

Each of the characters in Thundercats, even side characters and villains, show up at different times and have altered back-stories. Lion-O, who is the prince and heir to the throne, (voiced by Will Friedle), is accompanied by Tigra, Cheetara, WilyKit, Wilykat, Snarf, and Panthro, (who shows up in later episodes). Tigra, is Lion-O's older brother and fellow prince. Cheetara, becomes a love interest of Tigra and Lion-O, and is one of Thundera's clerics/royal guards led by Jaga. Snarf cannot talk, and is Lion-O's pet, while WilyKit and WilyKat are orphans and pickpockets, who are searching for a fabled city of gold. Panthro is a lost general, that was betrayed by General Grune, and left for dead.

Other notable cameos and appearances include Monkian, Vultureman, Jackalman, Pumyra, and the Berbils. A cameo appearance is even made by Larry Kenney, the actor who originally voiced Lion-O in the original Thundercats. Kenney voices Lion-O's father, Claudius, who appears in the first two episodes.
