The Sixteenth Doctor

Originally young and ready for anything that came against him, this incarnation of the Doctor was a man who felt despite his youthful image, felt older but wiser than his face suggested. The Sixteenth Doctor was the Doctor's eighteenth incarnation and this one felt like the best yet for him.
Tending to not really show much care about his home race of Time Lords, he showed a great passion for history in wanting to explore the past for what it truly was whilst realising that occasionally, he would accidentally let slip on things that would happen in due course.
In the end, he knew his demons would come and catch up with him. He wasn't good at saying goodbyes as proven when his first companion Elise decided to stay on Earth following the events of Vengeance On Earth and even when the departure of Macy Gray came along eventually at the end of Comrades In Silver. Ultimately these drawbacks to him knowing he could carry on but would carry on having to say hello and goodbye to every companion he meets and travels with would ultimately be his downfall as proven when the return of the Valeyard came along after a deadly battle with the Daleks as a chance to finally sneak into the Doctor's timeline once again. 
After a long and enduring battle over time and space, the Doctor's body had had enough and decided now was the time to regenerate. He had lived all in all for about 650 years which was good for an incarnation but he knew it was time to be someone else and as so, regenerated following the conclusion of "The Legacy Of The Doctor". 
==Biography==
===Realising His Identity In 1941 England===
Having been in the Tardis when it crash landed in 1941 England, the newly regenerated Doctor came out of the Tardis very confused and not quite sure who he was or what he stood for at all. After collapsing at the feet of the two soldiers who inspected the bomb crater the Tardis had landed in, the Doctor was taken to hospital in Central London where once woken up and more with it, he would soon ask to see Winston Churchill. Winston came along the moment he had remembered meeting the Doctor (Victory Of The Daleks) but when he noticed he looked nothing like what he had previously looked like, the Doctor had to convince him that the man he met was now him.
Upon finally getting to grips with his bearings, he began to help Winston whilst the Tardis was repairing itself. However due to the Tardis having leaked some regeneration energy following the crash landing, it resulted in the Sontarans attempting to create a war within a war. Thankfully the Doctor was there to stop them and save the Earth from a threat as part of The Secret War Of 1941. 
===Travels with Elise Jackson===
Shortly after bidding farewell to Winston in 1941, the Doctor took the Tardis for a spin-around across the universe. Eventually he settled on landing back on Earth again after seeing an interesting science experiment pop up on the news channels via his tv in the console room. The location was at the end of Southend Pier. It was during this experiment where he met Elise Jackson and ended up having to deal with a slight issue of the Flood. 
===Travels with Macy Gray===
Upon landing accidentally in the height of World War One, the Doctor found himself facing his greatest enemy in the Daleks. It was whilst taking on this encounter that he met Macy Gray. 
===Reunited with Susan===
After the departure of Macy Gray, the Doctor found himself reuniting with Susan once again in the Tardis to travel the universe. 
====Death====
Now inside the TARDIS and glowing with more regeneration energy, the Doctor managed to set the coordinates before setting the Tardis off back home to Gallifrey once more. He knew his time was up once more but as gallantly as he could, he was ready for what was about to come next.
