This week, EW is talking to three of the most iconic creators whove worked with the League.

How did that affect the tone and direction of your book?J.M.

Because we ended up with a bunch of, for the most part, B-level characters.

That gave us the freedom to take those characters and make them our own.

Because wed have had every editor of those characters down our throats.

You guys are writing Blue Beetle, Booster Gold, Fire and Ice, Oberon?

Do whatever you want!

Which I think at the time, people did not hold in high regard.

So they turned out to have very long lives.

My marching orders were to do a big dramatic finale.

It just evolved naturally.

But we never set out to do that.

The minute you sit down and think, Im going to be funny, youre probably screwed.

We just followed the characters.

Beetle and Booster really created that team, not us.

You had done a little bit of work on Avengers before coming to the Justice League.

The book was always, always changing.

Our Justice League is almost a separate imprint, you know?

If not its own universe.

It exists out there in its own wacky world.

Keith and I talk about the Giffen/DeMatteis universe.

I would love to see more from the Giffen/DeMatteis Universe!There was talk a few years ago…

The worst we ever did to [Beetle] was we had him gain weight.

He got fat and couldnt fit into his costume!

Ive done that to other people!

Im sure there are people going, I cant believe what he did to my characters.

You and Keith are currently working together on theScooby Apocalypseseries.

Matt Ryan is reprising his role as Constantine.

Its one of the best animated projects Ive ever been involved in.

Theres Jonn Jonzz daughter.

Oh, I created her!

Theyre talking about Hronmeer, the Martian god of fire.

Oh, I created him!

You feel these little bits and pieces of your own work popping up in these stories.

His head would explode!

Because they dont have to!

They have the movies, the TV shows, the animated shows, the videogames.

Why do they have to pick up a comic book?

And thats kind of a shame.

Were not limited by anybodys budget.

We can do whatever we want.
