Since then, the Master has been plagued by the four-beat sound of drums, believing them to be the "drums of war", and motivating him to become a would-be universal conqueror. His madness begun at the age of eight when he was taken before Untempered Schism, a gap in the fabric of space and time, as part of a Time Lord initiation ceremony. The Master grew up on his home planet of Gallifrey and became close childhood friends with the Doctor. He is also extremely intelligent in terms of science, manipulation, technology, strategy and negotiation: his only intellectual rival being the Doctor. Like every Time Lord, the Master changes his looks and personality slightly every time he undergoes regeneration, with many of the Master`s incarnations being noted to have an uncanny ability to escape certain-death. It has been noted that while the Doctor is time-traveling elsewhere, the Master is orchestrating the conquest and/or destruction of whole worlds and the rest of the universe. He seldom, if at all, did anything for others but himself, heralding himself constantly, and will ruin the lives/manipulate anyone in his way for personal amusement. The Master is also extremely narcissistic. This has served to make the Master one of the Doctor's greatest and most recurring opponents and also the one that has caused the most emotional pain to the Doctor during the millennia-long feud between the two characters. The Master is deeply megalomaniacal, misanthropic, and shows signs of psychopathic behavior as his greatest fear in the universe is being outdone by the Doctor, leading him to becoming obsessed with ruining everything the Doctor stands for. The Master could be seen as the villainous opposite of the Doctor: Cruel, arrogant, vain, manipulative, and lusting for power.
