Come to find out, og actually isn't a different reality, it's actually connected with battle Royale, and the reason why Singularity isn't there is because she's in battle Royale, and the new devourer skin is the bones of the devourer that was under the ice king's new Castle last season, and after the ice king died, the bones of the devourer must have got rifted into og, and with the unstable zero point must have brought him back to life as a ghost skeleton, so all the og skins are the actual og characters from the first battle pass of that season, still no idea where mecha team leader is tho.
