It's naturally going to have heft, if the image you posted isn't fabricated.
Unless if that's a fake image, this guy's gonna be heavy. He's got a ton of panels, which while light on their own, will add up. If this guy looks good, is large, and has play features appropriate for what's effectively a Decepticon fortress, I'd be willing to pay a pretty penny for him.
This is very off topic, but does anyone here have experience with the Mastermind Creations Azalea (IDW Arcee)? She's $60 on the aftermarket, and looks like a decent figure. I've no experience with 3rd party toys, so I was wondering what anyone else thought.
