->''"In the 80's, everything was '-tron'! Megatron, Voltron, ''Tron''... the movie. You get the idea."''
-->-- ''WebVideo/TheAngryVideoGameNerd''

"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 RuleOfCool. Sometimes it's a name, sometimes it's a device that doesn't really fit the suffix, but it's called that anyway.

Compare ThingOMatic, TheSomethingForce, LawOfAlienNames and XtremeKoolLetterz. See also {{Trope 2000}}, where an object's name is suffixed with a large number to make it sound impressive (and is sometimes used with this trope to make the name even more outlandish).
