But he hasn't brought in any of that stuff, at least not yet, and even some of them don't actually have to be brought in. Red was only recently made as the excuse for animal powers parallel to Green, it used to be just be powers/morphogenic field. Deadman, we've had Secret, there's nothing different. Don't see how the phantom zone's even a major cosmological thing, pocket dimension, it's simple. Stranger and Spectre don't really have a reason to be brought in, but can be handled without explaining them. Doom Patrol are even odder ones out then Phantom Zone....they're a hero group with nothing to indicate their existance. No explanation needed.

The speed force retroactively explains all speed powers, but Greg doesn't see the NEED to explain them, so there's no reason to include it in this series.
