Scattershot or perhaps a Decepticon Plane combiner team, still something that's sorely lacking in toys larger than a Micromaster. A second wave of Autobot cars wasn't unexpected, though a Hotspot repaint as Inferno or remould as Grapple were the discussed possibilities as a body.
I think it's safe to say that the reveal of Sky Lynx at Botcon 2015 came somewhat from left field!
Sky Lynx's original toy came out in 1986 and was a Dinobird that turned into a space shuttle paired with a Lynx that turned into a Space Shuttle ground transporter. The two items combine to form the transported Space Shuttle or a 4 legged flying Dinosaur monster. As a bonus it was motorised so the shuttle transporter rolls along and the Lynx & Monster could walk. This is one of the many toys of that period not released in the UK. Since then it's a character that's rather languished in oblivion, despite being an ideal candidate for a Beast Wars toy, receiving a name reuse in Cybertron and Beast Hunters and an encore reissue in 2008. The Combiner Wars version is the first attempt at a new version of the original character.
Sky Lynx comes in combined beast mode and the only assembly required is to take each of the swords and tab them together and into the tail. The beast isn't a bad replica of the original. looking fairly similar in shape and colour placement. It's VERY well articulated: Each leg turns at the shoulder/hip, rotates just bellow it and bends at the knee with a hinged ankle. In addition the front legs fold out to the sides at shoulder. The tail bends at base and a little way along. The first neck joint allows the neck to sit right at the front of the beast or recess back an inch. There's then a bending joint and then a rotational one: this piece of the neck feels very like a normal robot's arm, followed by another bending joint halfway along and the ability fold the head forward and open the jaw. The outer portion of the wings, in blue plastic, folds forward & back and the wings raise & fold back at the base. There's 5mm peg holes on top of each wing and on the rear things should you wish to tool him up and, thanks to the swords construction, a 5mm peg hole sticking out of each side of the tail.
It's a good beast mode.
The problems come when you compare it to the original. It can't walk and it can't separate into two different beasts. Your mileage may vary on how much this matters.
Let's transform him into shuttle mode. Close the jaw, straighten the neck and fold the first two neck joints back into the body. Unpeg the swords from the tail and fold what's left of the tail up to form the tail fin. Fold the rear legs back so the straight edge down the back of the thigh lines up with the join between shuttle and transporter/launcher. Fold the feet onto the front of the rear lower leg and swing each in 90 degrees so the soles of the feet are touching each other under the tail. Fold the lower leg on the front leg forward at the knee as far as they will go. Swing each out to the side 90 degrees. Fold the feet so they point back. Open up the panel covering the chest cavity. Swing each front leg in 180 degrees at the thigh swivel so the lower leg and feet occupy the chest cavity and close panel covering it. Straighten each wing so they're flat with the blue wing tips extended. Fold the wings back so they're either side of the tail & engines to form the shuttle wings. Fold the blue wing tips back into the tail locking the shuttle wings in place. Peg a sword in either under each wing or in each side of the transporter/launcher.
Again a very decent modern interpretation of the combined vehicle, but once again no electronic motion and non ability to separate. As before your appreciation of the toy will depend on how much your mileage varies on this detail. There's one slight problem I have with this mode: the shuttle has two additional tail fins mounted at a 45 degree angle between the upright tail fin and the wings. I could live with additional detail if they weren't swept forward rather than back.
If this had been released as a Toy during Generations Thrilling 30 I'd have bought it and liked it for being a lot of fun but possibly would have been a little more miffed at the loss of the ability separate the vehicles/beast. However since this is a Combiner Wars toy it does do a little bit more ....
I could not believe the madness of Sky Reign's combined mode when I first saw it! Here's a combined robot with a gold Lynx head, like one of Sky Lynx's original separate beast modes. The reason for the reversed side tail fins becomes clear here as the fold out to the sides and point up on the chest armour The torso is stable, unlike earlier versions of Optimus Prime & Motormaster, but lacks the absolute solidity of Silverbolt's torso mode for Superion and it's Galvatronus and Computron derivatives. You might see this as a bad this but if you're the sort that poses their combine robot this will give you a lot more movement you don't get with the other toys including the ability to swing the shoulders back. I like it, a lot, although I'm not 100% sure about using Smokescreen as one of the limbs: his colour mix of red, white and blue EXACTLY matches the torso making the others look a bit out of place. You almost want to swap him for something else.... or use four Smokescreens.
We can go no further. We must look at the deep dark secret of Sky Reigns SECOND Torso mode. Effectively the Space Shuttle is mounted on Sky Reign's back. Turn the head round and the shuttle becomes the chest, albeit with a rather protruding shuttle nose at exactly the wrong level! This alone would be enough to book him into most X-Rated Transformers threads but things get worse though. Much Much Worse! Do not even think about extending the shuttle head into dinobird mode. DO NOT DO IT! As odd as it may seem the shuttle chest mode may even have a use as there are rumours that a Sky Lynx recolour will form the torso of a new Liokaiser.
Sky Reign is marked to include Combiner Wars Wreck Gar as a member of his team but to date there's no indication of how he should be used in combined mode even if he can be used in combined mode. Defensor's chest armour is right out due to a lack of connection points.
I've had fun with this toy, I like it. Yes it would be nice to split into the separate components like the original did BUT the combined mode more than makes up for it I feel.
