Mine are an amalgamation of a few things: What I've read on TFWiki Transformers: Cybertron What I'm able to do with my own figures My own head canon In order of creation, with representative figure in parentheses: 1. Vector Prime (Cybertron Vector Prime) 2. Micronus Prime, AKA Safeguard (Cybertron Safeguard) *Vector and Micronus were the first Conjunx Endura 3. Epistemus Prime, AKA Alpha Trion and Sovereign (forthcoming Titans Return Alpha Trion) 4. Maximus Prime and Emissary (Perfect Effect Warden) *Fortress Maximus was built in his image and named after him. 5. Sentinel Prime and Infinitus (Titans Return Sentinel Prime) *Epistemus, Sentinel, and Maximus were jealous of the bond between Vector Prime and Micronus Prime, and tapped into Primus's creation energy to create their own Conjuges Endurae, from their own heads. 6. Nova Prime (Combiner Wars Battle Core Optimus Prime) *First combiner, can combine with any transformers capable of combination to form Nexus Prime. 7.

His colony planet, Eukaris, is home to Transformers with organic beast modes. 8. Colossus Prime (Cybertron Metroplex) *Second of five Primes to leave Cybertron to establish off-world colonies. His colony planet, Gigantion, is home to Transformers of enormous size. 9. Solus Prime, AKA Override (Cybertron Override) *Third of five Primes to leave Cybertron to establish off-world colonies. Her colony planet, Velocitron, is home to Transformers of immense speed, and has a disproportionately high population of female Transformers. 10. Quintus Prime, AKA Evac (Cybertron Evac) *Fourth of five Primes to leave Cybertron to establish off-world colonies.

Dragonus Prime, AKA Brimstone (Cybertron Scourge) *Last of the five Primes to leave Cybertron to establish off-world colonies, choosing exile as punishment for his role in the conpiracy to overthrow the other Primes (see below).

Saber Prime/Nemesis Prime (G2 Laser Optimus Prime/RiD Scourge) *Unrepentant in his role in the conspiracy (see below), escaped, changed his name to Nemesis Prime, and became the first Decepticon. 13. Megatronus Prime (Transformers: Prime Voyager Megatron) *Instigator of the conspiracy between himself, Dragonus Prime, and Saber Prime to overthrow the other Primes.
