The Fifth Doctor was the fifth incarnation of The Doctor in the Classic Doctor Who.
With his young looks, the Fifth Doctor expressed an interest in things associated with Victorian and Edwardian England: cricket, tea, fair play, good manners, and a keen interest in science and exploration. He was also a sensitive and profusely humane incarnation who did not make himself an imposition, preferring to be honest, reserved, and honourable. However, the Fifth Doctor was also less willing to compromise his morals, and became highly conflicted about what choices he could make in a crisis that were truly right. His hesitancy made him seemingly more fallible than many other incarnations, making those around him wonder if he was capable of resolving difficult situations. In spite of this, he was one of the most overtly fearless incarnations, and frequently found himself right in the thick of battle.
He always wore a piece of celery on his lapel, which he claimed would turn purple when he was around certain gases that were poisonous to him. His final companion, Peri, asked him what he would do if the celery ever turned purple. He replied that he would simply eat the celery, though it is unknown whether he was joking or whether this would genuinely help in some way.
He was the last Doctor to use the Sonic Screwdriver during the series' original run, as it was destroyed by the alien Terileptils early in his lifetime. He was the first Doctor to wear a pair of glasses when examining things, a trait later shared with both the Tenth Doctor and the Eleventh Doctor. He was also the first Doctor to wear trainers as part of his outfit, a trait again shared with the Tenth Tenth Doctor.
He was killed by contracting Spectrox Toxaemia, a form of fatal poisoning, and later regenerated into the Sixth Doctor.
He was reunited with the First Doctor, the Second Doctor and the Third Doctor on one occasion and once met the Tenth Doctor, making him the only pre-Time War Doctor to directly meet a post-Time War incarnation on-screen.
