The DC Universe is on the verge of a major shakeup. When Geoff Johns, Gary Frank, Ethan Van Sciver, Ivan Reis and Phil Jimenez's "DC Universe: Rebirth" #1 hits stands, DC Comics' entire lineup will feel the aftershocks of this game-changing issue -- and DC Entertainment CCO Geoff Johns promises fans will love it, money back guaranteed.

"If anyone wants to check out comics, wants to check out 'DC Universe: Rebirth' #1 and doesn't like it, they can mail it to Warner Bros., to me, and I will send them a check, I literally will, for both postage and for the book," Johns told ComicBook.com. "I will buy all these books back because I believe in this issue a lot. I think it'll do very well. I hope it does well. But I seriously will, I'll buy back this book."

"The only reason I write these characters is because I love them," he added. "The only reason I want to spread the gospel of these characters is because I love when -- like, when 'Blackest Night' happened, suddenly a lot of people were like, 'I like Mera!' I was like, 'Me too, that's why I put her in there!' And New 52 launched and people were like, 'wow, I like Aquaman AND Mera!'"
