1. Prima - First Prime and first Transformer 2. Vector Prime - Guardian of Time and Space 3. Solus Prime - First Female 4. Liege Maximo - Ancestor of most who would become Decepticons 5. Nexus Prime - First Combiner 6. ??? 7. ??? Prime 8. ??? 9. Alpha Trion - Author of the 'Covenant of Primus' 10. ??? 11. ??? Prime 12. ??? 13. Megatronus Prime - Inspiration for the Decepticon movement That is my current list of my guesses for placements of the thirteen (1, 2, 3, 5, 7, 11, and 13 are 'prime' numbers). We also know that there is going to be a first Minicon and a first Beastformer. Any other guesses/speculation concerning the others about anything? Since the Thirteen are supposed to be archetypes/highly influential to the modern evolution for Transformers, I am going to guess that only one of them is a flier (being the first), maybe even looking like a Seeker. Though we are expecting to learn more about Nexus, Solus and Vector in "Exiles" coming in September.
