I knew about that one, actually, but that's a 2013 set. I'm wondering if they'll ever make a set featuring the Overlord's true form (i.e. the humongous black dragon from the final episode of LEGO Ninjago: Masters of Spinjitzu) at some point in the future. That'd be sick...although the Garmadon/Overlord fusion is still a neat thing in the interim.

And you may have a point. But until we learn more, I'm going to assume that thing in Zane's eye is evil, or at least antagonistic in a friendly rival sense.
