Nindroid Drones are minifigures from the Ninjago theme released in 2014.
The Nindroid Drone has a black kimono with purple accents across the middle, and shows its mechanical origins with a long metal tube curving from the bottom left to the top right of the torso. The head has black printing and two red eyes as well as a ferocious expression, and a vertically-split mechanical face showing a purple ring and metal plating around the left eye.
The Nindroid Drone, like the Nindroid Warrior, is a mechanical soldier modeled after Zane. They have been created by the Digital Overlord to be stronger, faster, and more agile than Zane and to lack emotion. They normally wield two silver blades. They do not appear in the TV series.
The Nindroid Drone and the Nindroid Warrior share the same LEGO.com description because they are in fact the same character, but different outfits and designs.
This is a description taken from LEGO.com. Do not modify it.
Nindroids are high-tech fighting machines manufactured based upon the blueprints of Zane.
But they are the next generation of artificial warriors, stronger, faster, and more agile than Zane has ever been.
In addition, they have cloaking abilities that let them turn invisible.
This mechanical army serves the Digital Overlord.
Where Zane is able to feel friendship and more, Nindroids have no emotions.
They are completely cold and totally focused on accomplishing their mission.
Nindroids cannot be reasoned with or frightened off and they will only do strategic retreats if it seems that defeat is inevitable.
