Voltron: Defender of the Universe1984

King Alfor:
Listen, my young Defenders of the Universe; you must know this. When I invented the five Lions of Voltorn, I gave each a different power-source. The Black Lion gets its energy from the lightning that streaks the stormy skies. To move the mighty turbines of the Red Lion, I infused them with the elements that can only be found in the heart of a raging fire. The Yellow Lion's power comes from the magma that thrashes about deep beneath the planet itself. That the Green Lion may fly as swift as the wind, I harnessed the energy of a cyclone. Yes, these are the basic power-sources - all supplied by nature, which are infused in lions. When they all combine in Voltron, they give him his mighty strength and endurance to cope with any foe. He was designed to preserve the peace, and defend the universe.

Princess Allura:
But, Father, what is Blue Lion's power?

King Alfor:
The most ancient of all, my child: water. And until that dry lake in which you rest is replentished your Lion will lie helpless, like a beached whale.
