Dr. Genericius

Go To
He must be legit. His name ends in 'ius'.

By some weird reason, wizards and Mad Scientist types often have names ending on "ius" (possibly just "us", but "ius" is just better). It makes their names sound more smartass and at the same time badass.

Truth in Television with Vesalius and all of the other Medieval/Renaissance scientists who used Romanized names (Keys would become Caius, to cite a real-life example), the likely inspiration for the trope. It's frequently Canis Latinicus, though.

See also Dr. Fakenstein and The Great Whodini for alternate naming patterns used by scientists and magic-users respectively, and Herr Doktor for the German-sounding scientists.

  • Doctor Faustus.
  • Also Dr. Cornelius from The Chronicles of Narnia, a magician though not an evil one.
  • Dr Igneous Cutwell, from Mort is another non-evil wizard, and is unusual in that it's his first name that fits the trope.
  • The Vesper Holly series has Dr. Desmond Helvetius
  • Harry Potter, of course. A lot of wizards have names ending in "us" : Albus, Bartemius, Lucius, Regulus, Remus, Rubeus, Severus, Scorpius, Sirius ... It seems to be more frequent in the Pure-Blood families, though.
  • Joseph Sheridan Le Fanu's Occult Detective Dr. Hesselius.
  • The Crows Tower has Icherios Cain, the protagonist, who is an alchemist and is starting to study medicine in that book of the series. He is more or less sane, though most people might not agree, seeing as he keeps a rat as a pet ... A rat which, at this point, has licked up some immortality potion, and is not quite ... normal anymore.
  • The Fairy Oak series have Hibiscus Castle, a sheltered young Wizard from the village.

    Live-Action TV 
  • Dr. Cornelius from Doctor Who — a name which actually sounded somewhat jarring because of this very trope, given that he's an ordinary medical doctor.
  • Dr. Gaius Baltar from Battlestar Galactica (both the classic and reimagined versions).
  • Gaius, the court physician from Merlin (2008).

  • Professor Psychoticus, Mike Barson's alias when Madness were pretending to be The Dangermen.

  • The Descendants has Doctor Paralus, which is his actual name but the heroes are constantly mocking it as Powerless or Perilous. A Bad Future is shown where he does in fact become Doctor Perilous.

  • Dr. Viktor Capesius (1907–1985), Doctor of Pharmacy, physician and pharmacist in the Auschwitz death camp and right-hand man to another Mad Scientist, Dr. Joseph Mengele.
  • Paracelsus (1493–1541), Renaissance-era Swiss physician, alchemist, and astrologer, and the father of toxicology as a field. Already an example for his chosen name (Latin for "higher than high", or "surpassing Celsus", perhaps referring the Greek philosopher Celsusnote ), but an even more triumphant example for this page thanks to his full name: Philippus Aureolus Theophrastus Bombastus von Hohenheim.
  • Carl Linnaeus note  was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin, and his name is rendered in Latin as Carolus Linnæus (after 1761 Carolus a Linné).
