It was a ferocious battle between The Timelords and The Daleks but one man reached out for a heavy,powerful,full of ammo grenade gun and spelt 'NO MORE'.The Daleks detected the doctor so he sprinted with fear of the daleks and hid in a barn type hut where an old ripped leather chair stood still infront of him.This was not any ordinary chair because when the doctor dared to touch it a panel suddenly,as if from nowhere appeared covered with images of people who had never been born.
It took some time to realize that the images weren't just images but buttons.Every time an image was pressed he turned into the men that were shown on the image.Then he found an unusual thing that looked very familair from his childhood then he found a memory at the back of his brain and remembered what it was.A sonic screwdriver.
Suddenly he felt the urge to go investigate.Along the way he found a door which he knew was where the TARDISes (Time And Relative Dimensions In Space.)were stored.Soon he figured how to work one and crash landed on a place called Earth.
But he found out he did not need the chair to find out this destiny.He could could regenerate into different people along with his personality and his stolen/borrowed TARDIS.He was not alone because he had companions that were there to hold his hand whilst travelling,such as; Ace,Sarah-Jane Smith,Jo,Amy,Rory,Rose,Donna and last but she will never be least Clara
