"It's definitely the most destructive power Superman has," says Johns. "And he's not exactly excited about it because it is so dangerous and there are consequences."
Johns says that the power will be unveiled in the finale to Superman #38, calling it "very unstable" and something "Superman's going to have to deal with for quite a while."
Between the new power, the new costume and the new mindset Johns says Superman #38 will bring, Johns says it'll send the Man of Steel "in ways that we haven't seen in a long, long time."
"[This] just fundamentally has the character asking certain questions he hasn't asked himself and experiencing certain things he hasn't experienced."
