With the promise of the coming of new robots in "Transformers 5" comes the leave-taking of another. Rumor has it that in the much-awaited film, justice-championing and heroic leader Optimus Prime will bow down for his curtain call.

Filling the void to be left by the robot will take a lot of new machines. Optimus Prime's spot will allegedly be taken by the newest mechanoids on the block. Taking over for him and leading the charge will be Ultra Magnus.

This mechanoid serves as a chief lieutenant of Optimus Prime. He possesses great fighting skills that are often made dormant owing to his knack to shoot orders to other robots instead. Nonetheless, Ultra Magnus is a noble and courageous leader, making him perfect for the job.

There will purportedly be a fair share of good and bad in the movie. Hailing from the evil Decepticons are Blitzwing, Scourge and Cyclonus, which will be enjoying the spotlight in "Transformers 5." Bulking up the Autobots are Override and Red Alert.

According to media outlets, fans of the franchise are worried about the possibility of Optimus Prime being killed off. If he will bite the dust in the movie, it would mean that he will not be around in the four following sequels to the film.

Optimus Prime will allegedly battle the Quintessons, a five-headed alien breed that created the Autobots. This epic battle will allegedly be the focus of "Transformers 5" as well as Cade Yeager's attempt in saving the world with the dinobots.

The film's main villain will apparently be "Unicron," who has an affinity for chaos and a literal thirst for planets and solar systems. The powerful robot feeds on celestials of the galaxies, helping him gain more power and making him all the more dangerous.

"Transformers 5" will bring back Mark Wahlberg as Cade Yeager. Michael Bay will also be back in the director's seat. The movie is slated for a 2017 release.
