  • Trivia

    • This episode contains one of several times throughout the series in which a character appears to "break the fourth wall" -- the invisible barrier between the characters and the audience.  In this episode, it is Tygra when he speaks about rules being meaningless unless they are followed.

    • Weapon First Use:
      Slithe - Warp Gas
      Monkian - Shield Cannon

    • This is the first episode in which the Thunderkittens are told to stay home to guard Cats' Lair, which is partially completed, while the adult Thundercats rush into action.

  • Quotes

    • Tygra: Is that why you fought to free them, Lion-O? For thanks?
      Panthro: You wasted your time then... didn't you?
      Lion-O: I did not! I did it because... because... because it was the right thing to do.

    • Lion-O: Well, the Brutemen seemed to understand the word "free" all right, didn't they?
      Tygra: Everyone does, Lion-O. Even those who would deprive others of their freedom.

    • Slithe: So... I face the great Panthro. I am not impressed panther.
      Panthro: You're no work of art yourself, you scaly reptile.

    • Tygra: These poor creatures can't help what they're doing, Lion-O. You mustn't fight them.
      Lion-O: I won't fight them, but the Lord of the Thundercats can't run.
      Cheetarah: Lion-O, pride can be a good thing, but pride carried too far is foolishness.

    • Tygra: Rules are only meaningful if people agree to follow them. Otherwise they're just words.

  • Notes

    • Brutemen are a gentle, peaceable, and not highly intelligent race of creatures who are easily enslaved.
