At Toy Fair of 2018, Diamond Select Toys revealed their display figures for Sonic & Tails!
These larger 3D figures combine clear & solid color plastic for a feeling of action for each character.
The Tails figure has him reaching for a purple chaos emerald as he's flying through the air. The clear plastic effect here has an orange fade inside it, to give his tails the look of really spinning.

At the right is an exciting preview-look at the Sonic figure. Figures were released as Gamestop-exclusive in 2018 and later released in SegaShop (2019 for US and 2020 for EU). Tails' base can't be fully seen in the photo & the emerald may look larger than it really is due to perspective. (If it's supposed to be regular Chaos, Sonic's is the right size but Tails isn't that much smaller than he is) 

This Tails is a PVC, so not too costly or fragile, which is great for collecting.
