1The Doctor & The Master

Doctor Who (1963-1989, 2005-present)

Doctor Whohas been running for a very long time, seeing severaldifferent actors take on the iconic character of The Doctor.

Throughout the decades,The Master has stood in opposition to The Doctor, existing as a pillar of Time Lord excellence and often attempting to bring them back in newer seasons.

Though they so often stand in opposition to one another,The Master consistently holds a mirror up to The Doctor’s arrogance as an arrogant person themselves.This is especially true in the David Tennant seasons of the show, drawing out The Doctor’s arrogance and need to be the smartest in the room in a way that leads to The Doctor making deadly mistakes. The best example of this culminates in the final episode of David Tennant’s original run, with The Doctor saving the day at the expense of his own life.
