Doctor Demented did not wait idle as I attempted to kill him. He went out provoking fights with other people.
He composed a list of people he would need to provoke: Cognis, Genesis, and the President of the United States.
It was just after one o'clock, western time. Cognis was just beginning his daily two hours of sleep. He had just gotten out of Mephistopheles' custody. That was no reason to slack off. Tomorrow, he was going to put in a fully twenty-two hour day. Hopefully start to make up for all the time he lost to the extradimensional supervillain.
He was awoken by a crazy person pointing a glowing spear at him.
"Why are you here?"
"I want you to know. I plan to kill every being on the face of your planet Earth. Stop me if you can."
Cognis booted up his brain. Remember, it was the middle of the night, he never got any sleep regardless, and he had just been freed from a supervillain's clutches. "When do you plan on doing this? And why are you telling me?"
"Time is game for little minds like yours."
"And why are you telling me?"
"In hope that you provide challenge."
The weapon dematerialized. The armored god paced through Cognis' apartment. "You have parts of my army hidden around your world. You think you control it. You will use it against me."
Cognis wasn't surprised that the Doctor knew about the weapons caches. But he still didn't like talking about them. They were his greatest shame. A brutal weapon of last resort. Like something Phoenix would do. "I wouldn't trust weapons you created."
"You not think of anything better."
"I don't suppose they will work."
"This is the job they were created for."
"They were created to help you take over this Earth."
"Why would you do that? Are you trying to commit... is this about something that happened. Are you depressed over Nimue? Over your failing mental capacity? Talk to me about it. I'm the greatest psychologist in the history of the world. Let me help you."
"You are greatest psychologist in history of one tiny world, so far. You are nothing. You cannot fix my mind. You cannot even understand what my mind is. The best you can ever hope is to destroy my mind. Put me out of misery."
"I was wondering when you would arrive." Genesis was wearing a small body. Elegant and agile. He had decided that great physical power was inelegant. Genesis was no brute. He was experimenting with creating a great bull of dog to provide the physical strength his new body lacked. Demented was riding his most recent bull.
"In one day, I will kill every being in your garden."
Genesis tried to keep the fear out his his heart. This body had a reduced amygdala, but it did have large adrenal glands. A bug to be corrected next time around. "Why?"
"I destroy garden. You try to stop me. I kill you."
"You know I cannot stop you."
"Yes," the Doctor said. "But try."
Genesis began to formulate a plan. "Yes," he said. "I will try."
The president woke up, filled with fear and awe. He wasn't in his bed. He wasn't even on Earth. He was in some netherworld, confronted by some sort of demon or monster or something. "I am Doctor Demented. Greatest mind in history of universe." He frowned. "Broken mind. But great."
The president was scared out of his mind. But he was the president. This wasn't the first time someone had woken him with something terrifying. "That supervillain from a couple years ago?"
"I will destroy your planet. You cannot stop me. Others can. Call your Phoenix. Call your Professor Cognis. Call your Genesis. Offer them whatever they need. Maybe, they can stop me." The Doctor stared wistfully into space. "Maybe they can stop me."
The president was deposited in the burnt-down remnant of the White House. Firetrucks, ambulances, and military vehicles swarmed around him. The president went up to the first person he saw. "Give me your phone. I have to make some calls."
Lucy looked at the sad old man. "I hope you die soon."
"I will not." He raised his left hand. He wore a glowing red ring.
"Is that Alex?"
"Yes. Crucible. Greatest power source in known universe, compressed and trapped in my ring. That is my power."
"Phoenix will kill you. He can do anything."
"Phoenix is only one with actual chance. Anyone else to threaten me? They die. Phoenix cannot die. He has chance."
"He can do it. He saved me before. He saved everyone before."
The Doctor didn't hear her. That't because, for about twelve seconds, he forgot how to use any of his senses. "I don't remember you," he said. "What does it mean? Does it mean I kill you, and broken brain forgets the last year? Or maybe, perhaps young self does stop me. Erases you for your protection. But why? Already knows I find you. Perhaps you have some vital role. You help stop me, in way past self does not want me to know. Is same reason why I cannot remember this incident at all. Is so that I die with element of surprise." The Time Traveler let that hopeful thought permeate his mind. "Or maybe, you die in two days. And I forget you."
