Yeah but so does Metroplex, Fort Max, and Mattel's Voltron so you cut costs where you can. not saying it's a good thing it just happens. I might do a review on my blog when I have all of them

No, actually, none of those do. They have hollow spaces, yes, but all their limbs are fully articulated, and said spaces are usually closed off or disguised with some level of moulded detail. Metroplex/Fort Max even have articulated hands despite the cavities in them. The Saber Toothed Tiger's legs are one-piece completely empty things without even token moulded detail inside. Cerebros doesn't have unposable arms and legs. Like seriously, they're like cake moulds on the Megazord.

Also, I don't know which Voltron you're talking about, but if it's the upcoming 24 inch Voltron than holy cow you could not be more wrong.

No back about 2012 Mattel did a classic line with Lions that have cockpits and pilots and they combined to form a huge 24 inch voltron it nice but very top heavy and and weight change will throw it off balance it looks awesome pain in the ass to keep on a shelf.

That figure didn't have hollow, unposable limbs on its lions, either.

Don't forget the hollow spaces in the legs of Fort Max/Metroplex could be used in their other modes to store other figures so even if they have big hollow parts they at least used them to their advantage

The toys for this film look so cheap. I hope the Zords and morphers look better in the actual movie.

Could that grey thing be Alpha or Zordon? Seems weird to have a Putty Patroller on there next to Kimberley.

FYI, but the fangs aren't guns. There are still fangs.
