Reveals are fun and reveals at conventions are even better. My favourite part though is when it settles down and we can take a longer look at what we see and extract all the juicy info. While the reveals were few at Hascon, we now have a very good idea at what is in stores with Power of the Primes with our first look at particular new play patterns that were not on display before and are now confirmed.
Combiner Hands, Feet and Enigma of CombinationPower of the Primes is basically Combiner Wars 2.0, at least when it comes to Deluxes and Voyagers. People were wondering about the combiner feet and hands since they seemed absent from previous reveals. Well we finally got them this time. The voyagers come with a pair of feet.
You can see one of the feet here.
Combiner Hands and Enigma of CombinationEach deluxe comes with a combiner hand with 2 thumbs on opposite ends and an example can be seen in the image below. There is a hole in the middle that is titan/prime master and it is currently holding the clear plastic Enigma of Combination. You can actually see the titan/prime master compatible Enigma near the hand, it is a convex circle with a red cross and comes with Grimlock.

Here is Starscream's Enigma.

The hands will also be able to tab onto the chest (there is a peg hole on each dinobot deluxe chest to accommodate this) of deluxes to give them some sort of power armour and the combiner feet become gauntlets for the voyagers, as seen below.


With the 5 combining Dinobots, you end up with 2 feet and 4 hands and while that may seem redundant, it isn't since the extra hands combine with the combiner torso to beef it up, as you can see in the image below. It seems the distribution of these hands and feet among deluxes and voyagers is to ensure that buying any combination of limbs with a voyager will give a fan all they needs to have different pieces for the feet and the hands without resorting to boxsets, like the later combiners wars toys which did have different hands and feet pieces.

Also, it has been confirmed throughout the week that, as in Combiner Wars, every deluxe in Power of the Primes can be an arm or a leg.
Starscream's Combiner ModeTo be honest, it took a while for me to make sense of this because all I could see on the side of Starscream's box was ... Starscream again. But then I saw the crown and looked at his limbs and realize this was indeed the combined mode. Voyager Starscream's combined mode is King Starscream. The big nosecone in the robot mode's back finally comes into play since it hides the combiner head and makes up the chest with real kibble this time. The wings end up being what we see on the back of the solo robot mode, so we get all the alt mode detail they have here.
It is also very important to note that like he Optimus Prime voyager we got in the first wave of Combiner Wars, this toy isn't meant to team up with anyone specifically. He is just an extra torso to use as you wish since we see him with some abominus limbs.
Optimus Primal's Alt ModeThere was lots of confusion over this part and it is very understandable because the slide does indeed show a lot of contradicting artwork. However, as has been stated for the previously seen Predaking mock up, this means Hasbro thinks we fans are ready to see more into their process and are intelligent enough to understand what is a finished toy, what is a mock u and what is simply a character design. Below is the now infamous Optimus Primal slide from his reveal which shows the toy's process. On the left is the very first phase, the character design. At that point in time it is just an artist's rendition (in this case Emiliano Santalucia's) of what the toy could look like. The artist drew both a robot and beast mode for the smaller Optimus Primal and larger Optimal Optimus figures. You will then realize that none of what is seen on the left is what the final toy looks like.

On the right of that same image is the interpretation of that design into toy form by famed Takara designer Hasui (the guy responsible for your favourite Masterpiece toys, Combiner Wars Devastator and most Starscream toys). As you can see, this is where the actual toy starts becoming concrete. This is where we see that Hasui has taken the initial designs from the artist and made them work into the Power of the Primes leader gimmick where the smaller "deluxe" toy combines with the larger toy for the leader class robot mode. It is at that early stage that the toy desgner, Hasui in this case, chooses to remove the smaller gorilla mode.
For those wondering, the deluxe sized Optimus Primal turns into a long ship which becomes a surfboard for the Optimal Optimus gorilla mode. And then, the Optimal Optimus robot mode is only achieved when you combine both together since the surfboard (deluxe Primal) becomes the chest and the backpack for Optimal Optimus.

Hopefully this cleared up any questions fans may have had. If you have others, please reach out to us and the community on the
boards. We look forward to hearing from you!
