I have a theory that Scar is locked up in the AVP license but like Universal could with Halloween Horror nights Illfonic can release an AVP style Predator, it just can't be a film character. This would explain the naming as Scar would be under the AVP license but the marking wouldn't because it's still Predator iconography. You can't use Scar but you can use something that kind of looks like him essentially.
So at best it's someone we already know who uses the same style of gear (clan leader for example), or it's an approximation perhaps of all the AVP Predators to hit as many of those beats as possible due to licensing constraints. Likely not the same issue as fitting masks to a Super Predator noggin.
