Netflix debuted a new trailer for what is, at the moment, the final batch of episodes of Sonic Prime (barring a renewal). In it, we get to see the results of Nine's betrayal, and where this whole thing is going: Green Hill is disintegrating, Nine is seeking to build a new world in The Grim, Sonic's trying to stabilize the shatter spaces, and there are new robot versions of some of Sonic's friends! Oh, and Shadow is there, since he has some how managed to get into the Grim himself.
Check out screens from the trailer below:
The trailer does have not have a release date beyond "coming soon," though it's probably safe to assume this thing isn't dropping in October. Check out the trailer here:
