Since the dawn of the Transformers brand, a variety of unconnected media has conspired to create multiple continuities, even within individual franchises. The most famous such continuity split is the divergence of the original cartoon and comic, which contributed sometimes similar but ultimately irreconcilable versions of Generation One. While the most prominent continuities are well known, there exist many "micro-continuities": continuities about which only very limited information is available, yet which manage in that small space to be incompatible with the major continuities.
