The Thunder-Cutter

Mumion ruft den legendären Samurai Thunder-Cutter zu Hilfe, um die Thunder Cats endlich zu besiegen. Wie Leo besitzt auch Thunder-Cutter ein magisches Schwert. Doch die beiden Schwerter wollen ihrem jeweiligen Herrn nicht gehorchen.

Mumm-Ra summons the great samurai Hachiman to seek and destroy Lion-O. He tells Hachiman that Lion-O and the Thundercats are destroying his planet. Hachiman and Lion-O confront each other, but their swords refuse to draw on each other. They become allies and hope to destroy Mumm-Ra together. Enraged, Mumm-Ra summons another warrior, a ninja, to sabotage the Thundercats, and retrieve Slithe, whom they have captured.

Mumm-Ra invoca a Haichiman, un samurai ancestral y le dice que los ThunderCats son invasores malignos, enviando a Haichiman a destruirlos.
