Fun fact: The NRG minifigures have a different appearance then how they look in the series. Since in the show the NRG Ninja appear as their ZX forms (including shoulder pads and suit details), but glowing with light and made of or surrounded by their respective element (Kai becomes surrounded by a sphere of fire, Jay becomes an electrical being, Zane becomes enveloped by a pillar of light, and Cole becomes surrounded by orbiting rocks).
