What dark green and lime BIONICLE do I have?
My answer totally springboards off of Alexander "Hawk-Eyes" O'Mara's astute observation of its suspected authenticity.  Nice job Alex.

I looked up BIONICLE knock-offs and got a video that named the brand as "конструктор последний воин", then Google Image searched that phrase for a pic of our Greenie Meanie, and Voila!: 



Google translates the Russian/Mongolian to:


"конструктор последний воин": 

"Builder of the Last Warrior".
And this guy is named "ЛИЗОРД":

"Lizord" or Lizard.
The toy maker is, "1Toy Растем вместе!":

"1Toy Growing Together!".




There seems to be an entire, Builder of the Last Warrior line, with at least one dedicated community called RUSBIONICLE.
