True Potential

A "True Potential" is unlocked by all of the Ninja. The Ninja's true potential is when they are made up completely of their authentic element and have exceptional powers. To unlock your true potential, you must be completely at peace with your life and surroundings or have an exceptional need to do something very important.

Zane's True Potential
Zane's true potential surrounds him in an ice beam and allows him to float in midair. When he is in this ice beam, he can fly, shoot an ice beam, and have super fast Spinjitzu. Also, as shown in Once Bitten, Twice Shy, he can create an ice explosion. He reached it in the episode Tick Tock. So he was the first one to reach it. Zane unlocked his True Potential because he found out who his family was, and that he was a Robot (Nindroid by Jay).

Jay's True Potential
Jay's true potential makes him made of lightning and allows him to fly. When he is this form, he can fly, teleport, he has some-what super strength. He can electrocute anything he touches. He reached it in the episode Once Bitten, Twice Shy. So he was the second one to reach it. Jay unlocked his True Potential because he found out that Nya likes him best when he's himself.

Cole's True Potential
Cole's true potential surrounds him with a bunch floating rocks connected with lines. When he is in this form, he has incredible strength, indestructibility, and flight. He reached it in the episode The Royal Blacksmiths. He was the third one to reach it. Cole unlocked his True Potential because his Father respected him for who he was, not what he wanted him to be, making their relationship stronger.

Kai's True Potential
Kai's true potential surrounds him with extreme fire, making him sort of a flaming meteorite. It allows him to fly, but still leave the person inside it unharmed by the flames, as seen in the episode The Green Ninja when rescuing Lloyd Garmadon from the Serpentine. It also can allow to shoot intense blasts of fire, control the heat around him, teleport, and gives him somewhat superhuman strength. He unlocked it by swallowing his ego, and realizing that it's not him who's the Green Ninja, but Lloyd.
