10 Doctor Who Characters Who Can Never Die
6. Borusa
Like The Family of Blood, Gallifreyan President Borusa thought that immortality was exactly what he wanted. Everlasting life? Well that's a no-brainer! Only - and again like the Family of Blood - he didn't think about the fine print.
In 1983's The Five Doctors, this treacherous Time Lord is hell bent on gaining access to the Tomb of Rassilon, which he believes will grant him the secrets of immortality. Exploiting the intellect of the Fifth Doctor's previous incarnations, he does indeed manage to reach the Tomb, and sets about claiming his prize - only to discover that this forbidden, eternal fruit was sealed away for a damn good reason.
In one of the most perfect examples of 'be careful what you wish for' in the show's history, Borusa instead gets Ursula Blaked, with Rassilon's twisted version of immortality involving the recipient's head being turned into a concrete slab.
Turns out that Rassilon's game plan was to use the lure of immortality to capture power-hungry deviants - and Borusa just took the bait. Sucker.
