The Tornado of Creation is a move in the technique of Spinjitzu. It appeared in 2011 in the second pilot episode, and in season one, episode 6 & 13.
When four Ninja, with elements of Fire, Earth, Ice, and Lightning, activate their Spinjitzu, they can converge together to form the Tornado of Creation. The Tornado of Creation is nearly unstoppable, and is over four times as large as normal Spinjitzu tornadoes.
In episode 6: the Snake King, they used it again to go against the Samurai Mech. And in episode 13: Day of the Great Devourer, they used it to create the Ultra Sonic Raider. So far, the four ninja haven't used the Tornado of Creation since.
