Translucent Zzzax?

Eagle eyed Monkey on Fwoosh's forums noticed how one of Cool Toy Review's SDCC Super Hero Squad pictures featured a boxed version of (what looks like) Zzzax that's different than the unboxed Zzzax. It does look like the same Zzzax sculpt, only translucent, which was our chief complaint when we first saw him. Whether it's a variant or just an early production version like the matte paint/metallic paint Thors shown at conventions earlier in the year, or the paint differences between early shots of Ghost Rider's motorcycle and later shots, we don't know yet.
