Fire.
Everything around me is fire.
Billions of atoms fusing and splitting, bursting with cataclysmic amounts of energy.
The heat is unbearable, to say nothing of the utter crushing gravity that pounds me into the floor and keeps me from moving an inch. The pain had blasted my mind into a state of near delirium, my sanity just barely returning to myself before I realize just how much it hurts.
This must be what hell is like.
As it is, I'm at the heart of the sun. Trillions of degrees of heat as billions of years' worth of nuclear fire pour into me, the gravity of mass greater a million Earths crushing down on me. Like Jimmy said, I may be the only one in the universe capable of surviving this. And even then, it's one of the most excruciating experiences of my life.
Finally, after what could be minutes or hours or days, the roof slides shut. The heat dissipates quickly, the gravity returns to Earth-normal, and I start to move again.
After a few minutes, Jimmy steps into the room, looking a little older actually. Not by much, but maybe a year or so.
"Superman?" He asks, like he's trying to remind me of who I am.
"Are you....y'know, there? Are you okay?"
"I....I think so, I...." I try to stand up, and nearly crash right through the ceiling when I push against the floor.
"Whoah, you're gonna have to get used to that," Jimmy says with a nervous laugh.
"We're guessing your time in the sun has increased your strength and speed and your....well, everything else, by a pretty hefty number. Something like ten to the power of 36. I'd say you're about a fifth of the way there."
"What?! Jim, I'm not sure I can even survive another dunking like that."
I zoom in on the cellular structure in my hand, and I can see the damage that's been done. I've absorbed so much solar energy, it's causing my cells to burst. The matter in my body is breaking down, slowly--I'd still have maybe a year or so before the degeneration becomes fatal.
Still, I feel.....
incredible, better than I've ever felt.
"You're going to need to rest a little before you go back under," Jimmy says with a matter-of-factness that shows he's actually been studying this.
"The Ascension is going to multiply your powers to a level that won't be possible in the regular world for at least a million years. And frankly, we don't have that long."
"Why, Jimmy? What's going on out there? Mxyzptlk said someone was re-writing the laws of the universe, but who--"
"Darkseid."
".......ah."
Really, that's all that needs to be said. He is cruelty and greed and despotism at its most basic form. Evil in every sense of the word.
And according to Mxyzptlk, I have to kill him.
"I need to get back to Earth, now," I say, about to shove Jimmy out of the way before I realize doing so could break half the bones in his body.
"I've fought Darkseid before, and beaten him. With the power this 'Ascension' experiment has given me, I know I can beat him again."
"Two problems with that, Superman," Jimmy cautions me.
"First, he's not even on Earth, yet. The Crisis won't happen for a long, long time....relativistically speaking. See, when Mxy brought you back to our universe, he brought you back in time, too. Like I said, the power that we're looking for takes a long time to cultivate, and in the present, we just didn't have enough of it. So, in a sense, we're cheating."
"Cheating?"
"We've brought all of the Supermen from across the Multiverse to the heart of the Sun, and have been exposing you to pure, unleaded sunlight for a really long time. You've spent most of it in a catatonic state, with us giving you an occasional jolt to spend about a nanosecond of consciousness in order to keep for your mind from going completely. The only reason I'm still alive to see it is because I've been taking the fast route--time travel and such."
"It only feels like it's been a couple of minutes....how long was I charging up?"
"Ballpark estimate? Something along the lines of.....about ten thousand years."
I can barely wrap my mind around the idea of it.
Ten thousand years at the heart of the sun?! And according to Jimmy, I'm not even at the halfway point?!
"You can't....you can't be serious, right?"
"Serious as a heart attack, Superman," Jimmy says.
"This is Darkseid we're talking about here. When you've fought him in the past, you've fought projections of him, avatars, extensions of his will. Now you're going up against Darkseid himself, and the entire span of existence is going to need you to win. You're going to have to fight the very essence of the God of All Evil, and the Ascension is here to make sure it comes out right."
"And the other Supermen from the other universes?"
"They get the same treatment, then funnel all of their power into you. The combined power of every Superman from every universe, charging for fifty thousand years in the heart of the sun, all focused on one point: you. This is what the Ascension is for: we're not just going to make you more powerful, Superman. We're going to turn you into a god."
Jimmy's look doesn't falter in the slightest. When I left Earth, he was still just a goofy kid who couldn't help but get in over his head in trouble. Now, he's got the look of a man with purpose, as if on a mission from a greater power. It's strange, seeing him suddenly grown up and I've missed out on it.
"Take a breather and get some water. You go back under in ten minutes."
