The Transformers Universe

The Transformers Universe was a four-issue limited series published by Marvel Comics in 1986 featuring expanded profiles for the Transformers that had appeared thus far in the comic and toy lines. The entries were organized alphabetically, with the exception that characters who first appeared in The Transformers: The Movie were held until Issue 4. Each character had inked and colored versions of the character models and lengthy write-up, divided into three sections: Profile, Abilities, and Weaknesses. A header section gave the character's name, allegiance, function, and the issue number of their first Marvel Comics appearance, for those who had appeared in the book (which included the bulk of the entries).

Entries for characters from The Transformers: The Movie differ greatly in style from the rest, sometimes omitting sections entirely. The writing style for these characters suggests that their profiles are actually pre-production notes from very early in the characters' development, before their character models had actually been designed; Cyclonus, for example, is described as a "multi-engine, and perhaps multi-wing" spacecraft, with weapons such as "an incendiary bomb rack" which are clearly not present on his character model.

In 2015, all of these profiles, including the ones published separately in later issues, were reprinted together in The Transformers Classics, Vol. 8.

The name of the series was taken for the MUX, and the profiles are used as the basis for the Transformers' character notes.
