According to legend, Primus forged thirteen entities to protect the universe from his evil brother Unicron . Each was given a unique power, a cosmic function, and a sacred artifact.

These original Primes established the first principles of order, wisdom, and creation. They built Cybertron , forged the Matrix of Command, and spawned the lineage of great Autobot leaders like Optimus Prime .

Here are the most iconic members of the original 13 Primes and their responsibilities:

• Prima — first bearer of the Matrix of Command , symbol of purity.
• Vector Prime — master of time and space.
• Alpha Trion — guardian of memory and archives ( see its history ).
• Megatronus — future The Fallen , the traitor who made a pact with Unicron.
• Solus Prime — the blacksmith who creates sacred weapons and artifacts.
• Micronus Prime — mentor of the Mini-Cons and symbol of humility.
• Liege Maximo — the embodiment of deception and manipulation.
• Alchemist Prime — observer of nature and Energon flows.
• Nexus Prime — first to master the combination between Transformers.
• Amalgamous Prime — shapeshifter, first to experiment with free transformation.
• Onyx Prime — Guardian of wildlife and organic life.
• Quintus Prime — creator of life forms, originator of the Quintessons .
• Optimus Prime (in some continuities) — spiritual heir to the Primes.

Among the 13, Megatronus was the first to betray Primus' oath. Blinded by ambition and power, he made a pact with Unicron , giving birth to the very concept of corruption and chaos.

Becoming The Fallen , he was the forerunner of the Decepticons . His fall marked the end of the Cybertronian Golden Age and the beginning of an eternal cycle of war and rebirth.

Even though the 13 Primes have disappeared or scattered, their legacy remains in the Matrix of Command and the memory of Alpha Trion . Their wisdom is passed down through the generations, from Sentinel Prime to Optimus Prime .

They represent the moral and spiritual structure of the Transformers universe: the duality between light and darkness, between technology and divine essence.
