Love the concept and idea behind this...a cross-over that allows for Transformers at a compatible scale to G.I. Joe action figures. I would've been all over this if it had been available some 35+ years ago, back when I was cuckoo for cocoa puffs for both of these Hasbro franchises. Definitely looking forward to see what other Transformers/G.I.Joe collabs might end up seeing the light of day.
That said...like many have already mentioned, I'm kinda disappointed by this Megatron/Baroness set.
For starters...I personally think that a standard Cobra HISS is just not a worthy alt-mode for the mighty Decepticon leader. A bad-@$$ tank or armored vehicle of sorts...you bet'cha, absolutely...but just not
this model of HISS. Not really sure what Cobra vehicle would work for him though. The best ones I can think of or think I have seen before, they are all custom Cobra vehicles...often repaints and modified versions of various G.I. Joe vehicles.
Rather than Megatron, I would like to rather have seen a lesser-used Decepticon tank-bot...such as Armada Demolisher, or even Beast Machines Tankor. I like the idea of Tankor since...I can see where Cobra and/or the Decepticons could have legions of Tankor drones/standard HISS tanks at their disposal.
Megatron's fusion cannon looks like a joke sitting there on top of the HISS turret like it does. It looks very much like an afterthought, as if the designers just ran out of ideas on what to do with it. It doesn't look very well integrated with the vehicle-mode at all.
I do, however...like how Baroness can sit in the turret while Megatron is in robot-mode. That way, she can lean over just enough to slap him upside his head after he loses yet again to Optimus Prime...
