ThunderCats (1985)

Episode Overview

The Thundercats give Lion-O a quick demonstration of the time capsule they found from the caveman. Intrigued, Lion-O decides to activate it while on night watch, inadvertently getting caught in its projection rays. This leads him back to Thundera, just moments before the catastrophic tremor that would obliterate the planet. Meanwhile, the Mutants unleash a menacing robot monster that wreaks havoc in Cats' Lair. In Thundera's past, Lion-O encounters his father, Claudus, and heroically saves him from a Mutant ambush. Grateful, Claudus shares the blueprints for the robot that threatens the Thundercats in Lion-O's present.
