Tornado Machines were an invention that appeared in The New Adventures of He-Man.
The Tornado Machines were used by the inhabitants of the planet Zil to create violent rain and wind storms that covered their entire planet.
For countless Telks, the planet thrived in secret under the protection of these wondrous tornadoes, kept save from all enemy attacks. But eventually the machines begain to fail.
However, the people of Zil did not fear for the great legend promised them "When the crystal power fails, the champion will come". The people of Zil sent out a distress call, which was answered by two Galactic Guardians.
Spinwit was the first to arrive on the planet and saved the life of a young girl named Marika. The priests of Zil immediately proclaimed him to be the champion of the prophesy, or "Champion Spinwit" and his companion He-Man was deemed to be his faithful manservant.
