New characters are added in the rumored fifth instalment of Michael Bay's Transformers movie franchise.

According to reports from the Inquisitor, the possible new characters in Transformers 5 are Hot Rod, Primus, Unicron and the Quintessons. The website stated that Transformers 5 will likely focus on the origins of the Transformer race in Cybertron, and not to mention the Unicron saga. Further details added that the Autobot rookie Hot Rod will become Optimus Prime's successor as Rodimus Prime just like in the Generation 1 cartoon.

For those who have watched Transformers: Age of Extinction, the Transformer bounty hunter Lockdown mentioned in the movie that he was sent by the "creator" to capture Optimus Prime and deliver Autobot leader to him.

Transformer fans have speculated that the possible creators of the Transformer race in the movie franchise are Primus, Unicron, and the Quintessons.

Primus in the Transformers mythos, is the creator-god of the Transformers and a force of good in the universe. His twin brother Unicron on the other hand, is the Transformer god of destruction and the ultimate evil in the universe.

The two have clashed many times until Primus was able to defeat Unicron, and eventually transform himself into the planet Cybertron. He was also responsible for the creation of Vector Sigma and the all-powerful All Spark.

As for Quintessons, they are an ancient race of alien mechanoids that have been a part of Cybertron's dark history. In the Generation 1 cartoon series, the Quintessons were responsible for creating the Cybertronians as Cybertron back then was a factory of robots during its early history. They've rebelled against their creators for enslaving and abusing them, which eventually drove them off Cybertron for good.
