ThunderCats

S03E19 The Circus Train

Captain Bragg, a cunning bounty hunter, arrives on Third Earth to assist the Thundercats in their battle against the Mutants and Lunataks. He deceives Wilykat into joining him, and they set out to apprehend the Mutants first. After successfully capturing them, Bragg turns his sights on the Lunataks. They manage to capture nearly all of them, except for Luna and Amuk, who manage to free their allies and imprison Bragg instead. They tie Wilykat to the train's engine. Just in time, Lion-O and Wilykit show up to rescue Wilykat, leading to the defeat of the Lunataks. Ultimately, both the Mutants and Lunataks are captured and sent into exile.
