I like to study instruction manuals. Ok, I actually like to study anything that’s available. Anyway, I was flipping through the Instruction manuals for the new 2016 sets when I saw some interesting things. (Note that not all of these can be seen in all the Instruction manuals, so for best results, I recommend KOPAKA’s, a creatures AND Umarak)
On the page advertising the uniting function, showing all of the Toa united with their creatures, I looked at the background. You can see the Labyrinth of control, or what I’m assuming is the LoC anyway. At the far right is what you might at first assume to be Gali-Akida; BUT, the shoulders are wrong. This is, in fact, none of the Winter sets. This person is not visible in Kopaka’s, since his shield is in the way. Near the top, you can see Lewa-Uxar or possibly Umarak-Uxar, too hard to tell. Behind him, though, is a… lizard(?) thing. I’m not sure what this thing is, but it’s not any of the Toa, Umarak, or creatures. At the right, you can see Pohatu-Ketar(only in Kopaka’s) and Kopaka hanging from something (it’s impossible to tell if Melum is present, but we can assume he is). Near the bottom left on the Creature instructions, you can see Onua-Terak and a shadow trap.
Onua, Kopaka, Pohatu, and maybe Lewa are present. That leaves Tahu and Gali, but neither mystery figure is Tahu, Gali, or Umarak. The far left figure could almost be Gali but for the shoulders, but the Lizard thing is not Tahu. I’m willing to bet it’s a beast.
Sadly, the united figures and the app ad prevents us from seeing the full picture, so that’s all I can say for now.
So, the mystery figures are Lewa’s shadow trap and Gali. HOWEVER, Ikir and Tahu are the only two not combined. This may give us some hint to the story. Maybe Tahu and Ikir combine last? LEGO does tend to make the red guys ged power last (Vakama’s mask power, Kai’s full potential)
