On Earth C, could there be a Bec? Or some other form of first guardian but I would assume it would be another genetic copy of Bec. We don't really know what a pure first guardian can survive sans being beat with a juju and prototyping. So I figured there was a chance he could survive the watery apocalypse, even if it's a slim one?

It’s unlikely that there’d be a First Guardian for Earth C since the Green Sun has been destroyed and that’s where they get all their power from
