The Primes are a group of thirteen deities that many Cybertronians worship, believing them to be the very first Cybertronians created by Primus, and who each represent a certain idea or sector of Cybertronian society.
Primus - The basis of all Cybertronian and colony religion. Although deities themselves vary, Primus is usually always the creator.
In the most popular order of creation:
Prima - The first creation, victory, the beginning, protection, the first defender. The figurehead for ruling Primes of Cybertron.
Vector Prime - Space and time, observation, outsiders view. Justice systems often invoke Vector Prime's name in oaths.
Alpha Trion - Recordkeeping, history, the past. A member of the thirteen, but generally pushed aside in favour of the other primes. Not seen revered as a figurehead.
Onyx Prime - Beastformers, afterlife, and the natural world. Patron deity of organic features in Cybertronian society. Acceptance and differences.
Quintus Prime - Investigation, creativity, invention. Technology colleges often use them as a patron.
Solus Prime - Creation, rebuilding, recovery.
Nexus Prime - Combiners and change, mischief.
Amalgamous Prime - Transformation, fluidity, adaptability.
Liege Maximo - Evil, complete chaos, manipulation, selfishness. Regarded as a direct link to Unicron.
Alchemist Prime - Energon, sciences, experimentation. Another common patron of colleges.
Micronus Prime - Minibots, potential, small things, underdogs.
Megatronus/ The Fallen - Entropy, betrayal, being deceived, the ending of a cycle. Also a patron of perseverance, but this belief has mostly been forgotten in favour of "endings".
Thirteen - The one with the most varied idea of what they stand for. Varies heavily between bot to bot. Often represents Cybertronians as a whole in most beliefs.
