The Doctor's Ending
Batman's story:
The Doctor's defeat of Brainiac was ingenious. I never thought an alien warlord would be taken down by a screwdriver. After the fight, Superman and I started fighting again. The Doctor refused to let us go to war again. He locked us inside the TARDIS until we could reach an agreement. For the first 30 minutes, it seemed ridiculous, until the Doctor told us his story, from his first encounter with the Daleks, to the 27 planets in the sky. It became obvious to me and Superman that the Doctor has lost more than the two of us combined. Eventually we reached an agreement and the Justice League was reformed. However, the public refused to let Wonder Woman and Superman on the team, but I suspect the Doctor has something in mind for the two of them.
Wonder Woman's story:
I cannot believe the Doctor got Superman and Batman to reach an agreement. After that, the Doctor took me to the year 1972 when he was working for U.N.I.T. He was obviously trying to teach me a lesson, about what, however, I don't know. He showed me to a man named Brigadier Allister Gordon Lethbridge-Stewart. His men were 100% loyal to him, and they followed their orders without question. The Doctor then explained that they knew the Brigadier knew what he was doing. I then realized, he was a man who led by example. I see now that I was not the Queen I was supposed to be. In shame, I handed over Queenship to Donna Troy. I then decided to take up a position at U.N.I.T. Eventually, I became one of its commanders. So, let all invaders beware, U.N.I.T. has a new Brigadier. As for the Doctor, his work was not done yet.
Superman's story:
Upon hearing that the TARDIS was a time machine, I tried to convince the Doctor to go back and save Lois, only to learn that her death was a fixed point in space and time. I was upset, but still, the world was grateful for the Doctor's help, I decided to give him, as a piece offering, the last thing I had of Lois. It was her favorite pen. After looking at it, he pointed out that it was a 51st century sonic pen. He asked who gave it to her and I said it was a man named John Smith. Apparently, he sometimes goes by that name. After he opened it, it showed what he called a neural relay that lasts decades instead of hours. He said the neural relay had Lois's conscience. I was overjoyed. It took a while but after turning the android body of Red Tornado into a woman, Lois was back. At first, she was furious with what I did the past 10 years, but eventually things settled down. I had my wife back, but I still mourn the loss of my son. However, inside the pen the Doctor found a piece of plastic with what appeared to be blood inside, it turned out to be my son's blood. Using Lex Luthor's cloning technology, my son was finally born. I named him Jonathan Samuel Kent. For the first time in nearly 10 years, I had a family, and that has made all the difference. Thank you, Doctor.
Supergirl's story:
The Doctor knows my pain. I lost Krypton, just as he lost Gallifrey. In Brainiac's collection, he found millions of extinct species, Kryptonians, Daxamites, Czarnians, Thal and Kaled colonies, old Sontarans, and two of the cities overjoyed the Doctor. Inside Brainiac's collection were two cities from Gallifrey itself. Apparently, the Dalek Emperor allowed Brainiac to collect these two cities during the assault on Gallifrey, so he collected Arcadia and the Capitol City, just as he stole Kandor and Argo City from Krypton. The Doctor had an idea of how to restore them. He called upon all his incarnations, all 9 of his past incarnations, and three of his future incarnations. Using their TARDIS', they restored the cities in proper places in space and time. Kandor and Argo City, twin cities, reborn on Earth, in Antarctica. The Doctor set Arcadia down as an island in the Atlantic, and the Capitol City in the Himalayas. Two extinct worlds, reborn on Earth. As for the Doctor, he disappeared to God knows where. Wherever he is, the universe is in its debt eternally.
