Samurai X

Samurai X '''is a character in the 2012 line of Ninjago. Not very much is known about this character, but it has been confirmed that she is Nya in the episode "The Snake King". She repeatedly appears when the ninjas need help, except where she is gaining all the popularity by stopping the Serpentine attacks before the ninjas get there.'''

Appearance
Samurai X has a dark silver samurai helmet with a bucket handle piece on top in the place of horns and a red face mask. She also has dark silver samurai shoulderpads with a red armor suit underneath. In the show, she has technology glasses over her eyes and a big exo-suit.

Trivia

 * Whoever bought 9566 Samurai X would know that Samurai X is Nya before "The Snake King" aired, because without the helmet, the minifigure obviously has Nya's face.
 * In the TV show, she wears the same bracelet as Nya, so it could be predicted that it was her.
