"Everything was '-tron' in the 80's! Megatron, Voltron, Tron."

"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 devices for manipulating particles, 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.

Examples of NameTron include:

Anime and Manga

Card Games
