Abbreviations

Sometimes TransFans use shorthand to refer to certain Transformers series, toylines, episodes, characters, or other elements by acronyms or abbreviations. Sometimes you might not recognize an acronym or abbreviation, especially if it refers to a new series/episode/something you're only hearing about for the first time. Here's a guide to some of those abbreviations. Note that some of the links below go to their own disambiguation pages (such as OP, which can refer to any number of Optimus Primes, among other definitions).
