I dunno it doesn't really look that sus to me tbh. It looks like just generic "cool buff knight in armor dude" design to me. It's like those "tribal" tattoos to me, it doesn't mean anything it's just there as an accessory.

I guess it's possible the person that made that particular piece of content is secretely fash and it's actually a dogwhistle but I don't see it really. These kinds of motifs aren't really that uncommon.
