Megatronus is mentioned as one of the original thirteen Primes in the 2010 book "". Megatron is shown originally calling himself Megatronus, after this particular Prime, and is a gladiator, who then takes the name Megatron after the name is shortened by cheering fans at one of his matches. Megatronus, though the namesake of the Decepticon leader Megatron in the book, holds no sway over Megatron, who took the name simply because he had none of his own and wished to be associated with power and grandeur.
