10 Doctor Who Villains You're Surprised Only Appeared Once
3. Sutekh
Everyone forgets that the fourth episode is actually a bit rubbish, but 'Pyramids of Mars' is a stone-cold Doctor Who classic. It pits the Doctor against an Egyptian God imprisoned on Mars and introduces the Osirans, godlike aliens in the Doctor Who universe. There had been demonic aliens introduced in the Third Doctor era, but here was the show tackling the gods themselves.
Sutekh has never returned to the TV series, but one of his relations travelled with the Tenth Doctor in the comics! Gabriel Woolf, who played Sutekh in 'Pyramids of Mars' has returned to the series, playing the voice of The Beast in 'The Impossible Planet/The Satan Pit'. To date, however, no Sutekh! Having the Doctor take on an Egyptian god would be an epic season finale, so it's strange that it's not happened yet.
Now that the MCU is making Egyptology cool again with their Moon Knight series, maybe the 14th Doctor will be taking on the Osirans in a future episode. It would certainly push the show in a much-needed new direction, away from the alien invasion plots that have become overly familiar.
