Some billionaires in science fiction:

  • S.R. Hadden, is an engineer who is dying with cancer (reclusive billionaire industrialist)

S.R. Hadden, owner of Hadden Industries, is buried in space after dying of cancer on Mir in the film Contact. This is different from the book the movie is adapted from, where Hadden is not terminally ill and voluntarily chooses to leave earth in a space-bound "casket" while still alive. The "casket" is actually a small spacecraft capable of leaving Earth orbit for deep space, although the lack of any kind of superluminal propulsion means Hadden will undergo cryogenic hibernation to allow him to survive the thousands of years needed to cover interstellar distances.

  • Horace Bury

Blaine is given secret orders to take Horace Hussein Bury, a powerful interstellar merchant of Arabic descent who is suspected of fomenting the revolt for his own profit.

  • Mason Verger Mason Verger is the son of Molson Verger, a wealthy meat packer.
  • Billionaire Howard Christian, a character who appears to be loosely based on Howard Hughes but makes him look normal, has been seeking to clone a mammoth. A brilliant billionaire with an empty life and a drive to collect and amass.

Delos David Harriman, known as "D.D. Harriman," is a character in the fiction of noted science fiction author Robert A. Heinlein. He is an entrepreneurial businessman who masterminded the first landing on the Moon as a private business venture. His story is part of Heinlein's Future History.

Dr. Eldon Tyrell is the genius who has built up the large Tyrell Corporation. His creations are Replicants, some of which have been given away as an incentive for people to emigrate to the Off-World colonies. Others are used in combat to protect those settlers. Roy Batty, along with J.F. Sebastian, finds Tyrell, and asks him to extend his life beyond the four-year limit built into Nexus Six replicants. However, this request was impossible to satisfy. After the mutiny, when the limit was implemented, replicants were given superhuman capabilities in order to ensure maximum performance in this limited time; capabilities that burn them out like falling stars. As Tyrell states, "The light that burns twice as bright burns half as long, and you have burned so very, very brightly, Roy." Upon hearing this, Batty crushes Tyrell's head with his bare hands.
