The Doctor left Gallifrey and became a hero who fought evil and injustice across the universe in violation of the Time Lords' non-interference policy. Technically, he explored only with the intention of experiencing the wonders of the universe and having fun, but frequently became embroiled in machinations and crises that ended with him defeating the foe and saving the planet he was visiting. He travelled with many companions.
The Doctor fought in the Last Great Time War between the Time Lords and the Daleks. He was ultimately responsible for ending the war, likely with the action which resulted in the obliteration of Gallifrey, as well as the supposed extinction of both races, apart from the Doctor himself. The Doctor defeated the Time Lords by sealing them in a Time Lock from which they escaped with the help of the Master, but the Doctor re-imprisoned them, along with the Master, within the Time Lock.
