There are some leaked set photos and very interesting - and credible - rumours accompanying them. I’ll hide this in case anyone doesn’t want possible plot spoilers.

A very reliable source has backed up these leaked photos as real. Apparently these unknown red troopers will be fighting Din Djarin alongside Praetorian Guards from The Last Jedi. It makes sense that Snoke would be involved, related to the mysterious cloning plot they began in season 2.

I won’t name the source since evidence suggests they’ve done some really nasty things, but they’ve leaked things such as the Grand Inquisitor in the Obi-wan series, and the entire plot of The Rise of Skywalker, before.
