First 4 Figures is at it again!
At fabulous figures again, if these 2 versions of Shadow are any indication. F4F seemed to not have a big size Sonic franchise release in a while, but summer 2021 sees the preview pics of their upcoming Shadow figure. As you know, they enjoy always having 2 versions of something, and involving a light up feature. This is no different, with the chaos control 'energy flames' effect at the bottom having a light effect whether in orange for Super Shadow or Green for emerald-holding Shadow.
This figure 'gets out of the mold' (literally!) by being different from previous '2 versions' in a couple of ways. First off and most obvious is the base part of the base is literally different/textured differently (space for Super Shadow) whereas previous bases were identical save for the light effect. Then, Shadow is holding an actual transparent green Chaos Emerald in one hand while Super Shadow (having absorbed emeralds) has that same hand in a fist. The differences are interesting, make sense & look cool. 

It would be something that would easily encourage people to collect both.
As always, the sculpt is super really excellent for him. The pose is dynamic, he doesn't look 'cliche annoyed' like so many things seem to have him be, and the 'power effect' for the hand and base is also really well done. They get his super color correct as well (not yellow like SS, but its own shade) This one's going to be an absolute must for Shadow fans who have a lot of money.
