Newsarama: Greg, can you explain the process of Superman getting back his powers? Did this bullet with the explosion of toxins kind of kill off the mutated cells? And then the Fortress of Solitude could do its work healing him?
Greg Pak: Yeah. Way back in the promo story we did, at the beginning of the "Truth" storyline, for Action Comics, Superman goes to the Fortress of Solitude trying to get himself charged back up. But the Fortress of Solitude doesn't recognize him. It refuses to let him in. And since he's not strong, he can't pound his way in. And it actually reabsorbs his cape and his uniform. And he's left abandoned outside the Fortress. It's a crushing moment.
What we eventually learn during the course of the storyline is that these machinations that Vandal has been undertaking to drain Superman's power have — it's based on Superman's cells mutating, and they're not processing the power of the Sun like they used to. And they also make him unrecognizable to the fortress.
But what happens during the course of the story is Superman undertakes this Kryptonite treatment in order to power himself up, and the Kryptonite kills off those mutated cells.
And then when Vandal shoots him, it sort of finishes the process.
Nrama: It's interesting that Superman has to hurt himself with Kryptonite before he can heal.
Pak: Yeah, it's this sacrifice that Superman made. He basically let himself be killed off in order to try to save the day. And it ends up stripping away those cells that made the Fortress not recognize him.
So in the end, that sacrifice actually lets the Fortress recognize him again, open up and bring him in and restore him. It's a sacrifice leading to restoration.
And ha-boom, he's back!
