In the fall of 2018...there finally appears the figure for Sonic Forces' villain: Infinite!
Apparently, Tomy didn't have the figure ready when the game was released / to capitalize on the hype when the game was freshly out. However, better late than never because the figure is decent looking, as you can see here. They've got the details like pointy glove claw tips, opposite-color ear-interiors and the texture of the mask. The wiggly 'hair' spikes & tail bits are all there too.
Like their other figures though, he does not have knee or elbow joints. This is to scale with the rest of their 3.5 inch or so figures.
He can be found at Target (maybe in stores, but probably sells out right away) MAYbe in a 3 pack, for 20.
TODO: Other figures of this pack (as seperate articles? ) + additional photo's of the full package
