Prologue
Gotham, Earth 23, year unknown.
The Joker and Harley Quinn walked away from the burning building behind them carrying all the necessary components for the Joker's next great trick, the time machine. They walked towards an old small museum column in front of the building and went inside. "Wow it really is bigger on the inside isn't it Mr.J" Harley said observing the gigantic room inside the column, "Yes it is isn't it." The Joker replied while he was fixing up the bottom of a table like console. "Harley be a dear and hand me the last wire could you" The Joker said as Harley looked for the last wire. "Why do we need to build a time machine Mr.J? I thought you didn't want to create any problem for the bats." Harley asked, "hahahaHAHAHA" the Joker replied " Harley, Harley, Harley, you wouldn't understand dear, I have one more enemy to play with before I handle the bats." He flicked a switch on the console and started to laugh as the column faded away, his laugh echoed through street as it disappeared from sight.
-Two days later-
The streets were empty as a blue police box faded into appearance, pushing away the tumble weed leaves and ashes in front of it as it appeared. A tall man opened the door of the police box and walked out. He was 1.83 meters tall, wore a black suit with a red silk inner coating and tie, and had light brown/grey hair. His name was the Doctor. "Come out Clara, didn't you want to see the universe" he shouted into the box, "Im coming" a voice replied from the box, from his 'assistant' Clara, as she stepped out of the box. "Where are we Doctor? And why are we here's?" Clara asked, "Gotham, alternate universe 23, around the 20th century" he replied. "A strong disturbance in the time vortex is being produced here" he added, waving around his Sonic screwdriver. "We should go investigate it might be dangerous" he said. "Ok" was the answer that he received from Clara as she picked up a letter from the floor. "Have you found anything yet Clara" he asked. "Yes" she replied handing him the letter she found with red ink addressed to the Doctor. The Doctor read the letter to Clara, "JOKES ON YOU DOC. SINCERELY THE JOKER". "What does this mean, it's clearly addressed to me from whoever or whatever this joker is, but that doesn't make any...". The doctor was interrupted from his self thinking when a sharp pain occurred in his body. "DOCTOR!" Exclaimed Clara, "What's happening". "My past is being rewritten Clara just like with the possessed Doctor Simeon." He said before being knocked unconscious by himself.
