Mezco have teased this image for their 5 SDCC exclusives for 2016. Out of all of them, the classic Captain America image stands out - but we will now wait and see for these to be unveiled.
Talking of unveiling, this image has been confirmed as a Mezco One:12 Collective Captain Rogers, which will be a Previews Exclusive.
As an aside, Mezco are also working on a One:12 female body and are hoping to unveil their first female figure at SDCC. They have also talked about a Pinhead and an Evil Dead 2 Ash figure who will all fall into a Horror range alongside the Universal Monsters.
