Dynasty of Primes

The Dynasty of Primes (プライムの王朝, Puraimu no Ōchō) was the ruling class of Cybertron eons ago. Formed by the first Cybertronians, rightfully huge and powerful, each was designated a Prime, the Dynasty given unique roles and natures to rule Cybertron and protect the AllSpark until they were betrayed by one of their own.

"We are the the first, the forgotten, each of us serving a function vital to the survival of the universe. Each of us designated a Prime and given a function to protect the AllSpark. We are, The Dynasty of Primes!"
