Here is a MIB Toy Island first 5 (or really 6-ish) inch figure line Sonic. As you can see, these were the "not very good faces" ones. He's in the 2nd package (Sonic X theme instead of Sonic Adventure 1) which gives an idea of the release time-frame. The words on the box are all in Japanese (see tiny at the top & bottom) so you can't read it. He only comes with 2 emeralds, and not any of the tiny metal rings. Did only TI Sonic release there, or did they do the other characters from the set too?
Since toys in Japan tend to be a little costly (import fees only add to it) it's probably a good bet this guy didn't sell well. The X art on the box only serves to highlight just how NOT like Sonic the goofy, cross-eyed/big-eye hunched figure inside the box is. Still, this packaging is interesting to see.
