ThunderCats on Screen
ThunderCats ran 130 episodes from 1985 and returned for a 26-episode reboot in 2011. Full catalogue of episodes, cast, characters, encyclopedia. Rankin/Bass built a sister show around the same studio and the same composer a year later. This is the hub for the shows themselves and for everything the production left behind: the scripts, the voices, the score, the art and the animators.
The Series
1985 – 1989 · Rankin/Bass
The Original Series
The flagship Rankin/Bass production. Lion-O grown to manhood in suspended animation, the survivors of Thundera carving out a new home on Third Earth, Mumm-Ra in his pyramid, sci-fi and fantasy blended around a strong moral centre. Animated in Tokyo by Pacific Animation Corporation.

The 2011 Reboot
A grounded, serialised retelling of the origin. Studio 4°C brought a different visual language. Michael Jelenic and Todd Casey ran the writers' room. The single season was cut short but landed as one of the most loved reboots of the era.

The full fan guide: the story, the heroes, Mon*Star's mob, the score, screengrabs and clips. 2 character profiles so far.
