The man walked casually through the vast halls of the lunar fortress. They gleamed with an otherworldly iridescence, their alien alloy shedding the by-products of its chemical reaction with oxygen into the visual spectrum. The man grinned slightly, and a young photographer in a bustling metropolis was blind due to this previously harmless display. The walls changed as the man walked, becoming simple titanium, then steel, then the slick concrete of an underground bunker. The man pushed open a rusting metal door, entering an austere yet still somehow squalid, living room. A costumed superhero sat on the couch; he looked up as the man entered.
"This isn't right," the superhero said, staring down at his hands. "This," he looked around the room, "this isn't my fortress."
"Of course it is," the man said. "It's always been this."
"But, I--" the superhero shook his head. "No, you're right. I dug this out with my bare hands, then used my powers to make the concrete out of rocks and sand. It's useful, I guess, as a headquarters... but I could have done so much more with..." He kept shaking his head, as though to clear it. The man grinned again. The superhero blinked. "My homeworld... there was technology there that was millennia beyond what Earth has. I..." he looked helplessly up at the stranger in his fortress. "I should have access to that, shouldn't I?"
"No," the man shook his head. "Why should you? Your father destroyed your planet and everything on it. If your mother hadn't launched you into space when she did, your father would have destroyed you too."
"But, my ship--"
"Exploded once you were removed from it. It killed your Earth father instantly, and left your adopted mother a cripple, addicted to pain killers and vodka." The man smiled. "Don't you remember how you discovered you were invulnerable?"
The superhero touched his cheek. His bright costume was gone, replaced by tight leather. "She hit me," he whispered. "It was her wedding anniversary, I should have remembered that, and she always drank more than usual that day."
"Yes," the man said, "she was usually a reasonably functional alcoholic."
The superhero glared at the man, his eyes glowing red. "She was a good mother," he growled.
The man just continued to grin. "Except when she wasn't."
The superhero shuddered. "Except then."
"But you put a stop to that."
The superhero looked defensive. "I didn't mean that," he insisted. "The powers were brand new, I couldn't control them and I--"
"And you were really angry at her."
"NO! No, I... yes." the superhero sank back down on the couch. "Yes, I was angry. But I've done so much since then, so much good. Do you," he looked up at the man, his eyes haunted, "do you think she'll forgive me now?"
"She might have," the man nodded, "if not for what you've been up to lately."
The superhero looked confused, "I haven't been up to anything." Then both men looked toward the closed door leading to the bedroom. The superhero shook his head. "But she's just spending the night. She often spends the night here in the..." he shook his head again. "No, no, that's not right." He looked back at the door, a squint indicating he was looking through it. "I thought she was someone--"
"Someone else?" the man cleared his throat. "But that isn't possible, is it?"
The superhero shook. "No," he whispered. "No, I definitely didn't mean to do that to her. I loved her." His look was one that begged forgiveness. "I told her the serum was experimental. I told her! But she insisted on taking it. Wanted to be with me so badly that--"
"That she swallowed a serum that burned her from the inside out," the man said. He gestured toward the door. "And that poor girl..."
The superhero was on his feet again. "But the serum worked on her! It worked! I watched bullets bounce off her, I..."
"Yes, the serum worked perfectly on her," the man agreed. "But then, all those experiments you used her for when you were kids likely helped. Did she ever remember what you did to her all those years ago?"
The superhero was silent.
"So yes, it worked," the man agreed. "But then you went and lost track of time. It was late when you got back to your little fortress bunker, and by the time you two were well into things..."
"It wore off." The superhero's voice was a mere whisper. Then he looked up again, suddenly really noticing the strange man in his inner sanctum. "Wait," he said. "Who are you?"
"I'm just a man," the man said. "A man with a special power." He smiled. "Nothing so grand as your impressive abilities, but quite potent in its way." His smile deepened. "I can reach back through time," he explained, "and alter key events in any person's history. I can change the very continuity of someone's life."
"Did you change mine?"
The man nodded and laughed. "Oh yes."
The superhero snarled, leaping at the man. "Change it back! You change me back to whatever I was right god-damned now! Or I'll--" He fell to his knees, muscles atrophied and bones brittle. His words were choked off in a dry rasping cough.
The man laughed, shoving the dessicated superhero onto the floor with his foot.
"You'll do nothing," he sneered. "I'll retcon your radiation poisoning away after I've left," he promised. "I want to keep you around like this a while." He checked his watch. "Ah, yes, well. I must away. I've a brooding man in a cave to visit and grant his fondest wish." He smiled and exited the bunker, stepping into the razed slums of a once-vibrant city.
"Be seeing you."
