The Mighty Space Mouse, the 46th episode of Voltron: Defender of the Universe, introduces X-47, a mighty robot for the Space Mice to ride. Defender of the Universe juggled seriousness and humor from episode to episode, but The Mighty Space Mouse might be the best example of balancing both in the same episode. Every scene with the Space Mice would be dramatic if it featured the human characters. An intense boot camp. Mastering a new weapon. Confronting their mortal enemy, Cova the blue cat. Keith
