As it turns out, DC was just getting started.

EW caught up with Snyder to process this jaw-dropping revelation and discuss what else theMetalcreators have up their sleeve.

ENTERTAINMENT WEEKLY: Sandman is one of my favorite things ever.

I was walking around my office screaming after I read this issue.

Theyre sort of created or destroyed based on our dreams and nightmares.

Its really a world thats reactive to the things we dont want to admit we want or dont want.

Its a realm of dream, of the subconscious.

Even though were friendly, to ask that of him was hugely intimidating.

Instead, he wrote back and said, I love it, go for it.

That was the whole exchange.

I was like, Are you serious?

Just to be clear, this is how Im going to use him.

He was like, Oh no, go ahead.

Hes been incredibly generous with his creation.

I know it back to front, Ive reread it a number of times over the last couple years.

Its so crazy seeing Dream interact with Batman.

It wasnt just writing Dream, it was doing what you said, it was making something connective.

It really is about connecting all the new stuff that were doing to our favorite material from the past.

Not just the Justice League its got Dr.

Fate, Steel, Plastic Man, Mr.

Terrific, and the whole cosmos.

For Dream, I would say there isnt a more important role in the story than his.

He comes and goes.

On the one hand, it has this literal meaning.

I started thinking, whos been the detective of history in the DCU?

Hawkman came up for me.

What if dark energy is coming through this material in Hawkmans mythos, Nth metal?

Theres that alloy of characters that way.

All the strange substances, from Kryptonite to Prometheum to Hephaestus forge.

What if this crazy message starts coming through these substances and affecting this world?

Then the third way, the biggest, is we want it to be fun.

The world is stressful.

Its been a rough year.

Ive certainly felt like that at different times in my life.

This story is in no ways an escapist fantasy.

I love that early stuff, Black Sabbath, and the musicality of it.

And then we have these fun editorial notes like see the 90s.

Before doingMetal, you and Greg spent years creating a hugely popular Batman run.

Superman has Batman and is like, What are you doing?

Theyve been secretly infecting me with different metals.

And you see all the different points in our run, like Remember this?

It totally connects for me.

All that stuff is pretty connected.

Its meant to take all those threads and say, You thought Batman was in charge but he wasnt.

All of those stories were actually just a prelude to this.
