Name Tron
"In the 80's, everything was '-tron'! Megatron, Voltron, TRON... the movie. You get the idea."

"Tron" is Greek for a form of instrument (such as the "Metatron" from mythology was an instrument of God). These days, it's used as a suffix for advanced electronic technology in general, because of that latin word "Electron".

But this trope is about how in fiction, it's used as a suffix just for Rule of Cool. Sometimes it's a name, sometimes it's a device that doesn't really fit the suffix, but it's called that anyway.

Compare Thing-O-Matic, The Something Force, Law of Alien Names and Xtreme Kool Letterz.

    Comic Books 
  • Ultron, recurring foe of The Avengers. Could be a portmanteau of the prefix ultra- and tron.
  • In addition to the roster of infamous Transformers characters, the rare Transformers In 3-D comic had a group of Canon Discontinuity villains called the Destructrons.

  • TRON is so awesome that it doesn't need a prefix. The creator stated that the inspiration was a shortening of electronic. By complete coincidence there is a "tron" commandnote  from several varieties of the BASIC programming language.
  • One of the Puppet Master films (no relation to the Heinlein book) had a doll called the "Decapatron".
  • Orgasmatron from the Woody Allen movie Sleeper.
  • Speaking of Metatron, Alan Rickman plays one in Dogma.

  • Doctor Who has a Dalek that an ignorant collector calls "Metaltron".
  • Community has Boob-a-tron, a cardboard robot made by Abed in the hopes that someone will spill bong-water on it, causing it to become sentient.

    Tabletop Games 

  • Absolutely everywhere in LEGO's many space factions in the 1980s: Futuron, Blacktron, M-Tron, Unitron...
  • Several Transformers have had this over the years, most notably Megatron and Galvatron, and the Transformers' home planet of Cybertron. Other notables from the toylines include Banzai-Tron, Magmatron, and Computron. In Japan, quite a few evil factions have been known as the Destrons, while their good counterparts were known as Cybertrons (the planet was called Seibertron instead).
  • The Gobots have the homeworld Gobotron.

    Video Games 
  • Protectrons in Fallout 3
  • Positron from City of Heroes, who's named after the real-life antimatter counterpart to the electron.
  • The Syndicate games have a mind control device called the Persuadertron.
  • In My Sims, one of the tasks you may get from Dr. F is to build a Zap-o-Tron. Apparently, its function is to sit around, and when a Sim touches it, it zaps them.
  • The Enertron in Chrono Trigger gives you a full night's sleep in a few seconds. HP and MP restored! ...but you're still hungry.
  • Kingdom of Loathing has the Annoy-o-Tron 5000, which emits low-frequency waves that enrage monsters all over the Kingdom, making them slightly tougher (and worth more experience).
  • Tron Bonne from Megaman Legends, though she's actually a human girl.

  • World of Warcraft: The Burning Crusade features a Fel Reaver named Negatron, obviously as a reference to Megatron.
  • Skeletron of Terraria though it's not actually mechanical. Skeletron Prime, on the other hand, is a definite example.
  • Vectron for the Intellivision was inspired in gameplay and name by Tempest, which had vector graphics. (The "tron" suffix came to be because the game's Working Title, Vectrix, was too similar to the recently announced Vectrex.)
  • The Psychotron, an "Interactive Mystery Movie" from the mid-1990s.
  • Quazatron, the ZX Spectrum adaptation of Paradroid, and its sequel Magnetron.

    • The University of Texas has one that is over 7,000 square feet. It's nicknamed the Godzillatron.

  • Not related to high-tech, but the Modern Hebrew word for circus is "ziratron," from "zira," ring (i.e. the shape), and "teatron," theater (from the Ancient Greek "theatron"). Also don't forget Metatron, an angel in Judaism. This stems from the original Greek root.
  • "Waitron" is a gender-neutral version of "Waiter/Waitress." A professor I know once claimed to have coined the phrase as a joke, something about equating being described with genderless terminology and being a genderless automaton. He didn't expect the term to catch on.
  • The "Orgasmatron" is...a head massaging device.
  • The Cyclotron, a type of particle accelerator.

  • Let's not forget the Mellotron, a tape-based, pre-sampler keyboard instrument that was capable of reproducing realistic recorded sounds, especially strings, flutes and choirs.
