Certainly, those same stories by 3H were incompatible with later lore of the Thirteen, as they introduced Primon, a Matrix-bearer who preceded Prima. Despite the basic similarity between the Covenant and the Thirteen, there was no canonical connection between the two groups, aside from an ambiguous Ask Vector Prime entry published much later in 2015, which presented several different interpretations of how the groups might be related. Written by Simon Furman, this story introduces the undeniably similar concept of the Covenant, a group of twelve zodiac-themed robots who are the first creations of Primus, created as a test-run for the Transformer race. The very earliest seeds of the Thirteen can be found in material produced by 3H Productions for BotCon, most notably 1999's " Covenant". The development of the concept is described in this section to minimize confusion for details of their history and actions in specific bits of fiction, see below.

The concept of the Thirteen wasn't introduced until around 20 years into the Transformers brand's history, and the slow drip-feeding of information that characterized the early stages of their story has not been presented in a very linear manner. The Covenant shares the same base concept with the Thirteen, and served as the prototype for them.
