Here is my review on LEGO Sonic the Hedgehog 76996 Knuckles' Guardian Mech:
THE GOOD:
The Knuckle minifigure.
The play feature with Rogue's glider is a nice surprised.
THE NOT SO GOOD:
The mech lack articulation joints to allow better play.
The mech also looks surprisingly thing and flat from some angles.
Honestly, I bought this set purely for Knuckles given me played a good deal of Sonic 3 & Knuckles, it just feel incomplete without the Knuckles Minifigure. It's great LEGO releasing him in a set that does not break your bank. The minifigure is very well done, so does Rogue. The only things I wish it had happen is Knuckles's hands to be a new hand element rather than an accessory clipping onto the hands. The gloves are very well made though. Now, the mech build is your typical mech build and given the price of the set, it does not allow much details. Lacking articulation on the knees really take out most of the fun. The build itself is ok while it looks uncharacteristically thin and I'm also surprised to see no stickers, in fact I think the printed nexo knight shield piece would be very useful in other mechanical build. The other thing I was surprised with is the the gem stone play feature, you can used Rogue's glider and connects to the big gem and fly away with it. And that's pretty much sums up this set. It's a must have if you like Sonic the Hedgehog in some capacity, otherwise nothing much would stands out for LEGO fans which has no interests in this theme.
