Fandom

"These fools worship Transformers!"

- Astrotrain, "The God Gambit"

The community of Transformers fans is referred to as a fandom. While the term technically encompasses any group of kids coming together to talk about Transformers in a sandbox, it is commonly used to refer to the people from college-age and up who participate in the online fandom. The fandom has long played a role in the history of the franchise. Most notably, BotCon is their Mardi Gras, an official convention geared almost totally to adult fans.

Individually, or as a group, Transformers fans can be referred to as Transfans. This may raise eyebrows among the uninitiated, but it sure beats "Trannies."
