In the Transformers: Rise of the Unicron (2024) teaser trailer, the fate of the universe hangs in the balance as a new and terrifying threat looms. The trailer opens with Optimus Prime’s (voiced by Peter Cullen) familiar voice echoing through space: “We thought the war was over… but something far greater is coming.” The screen cuts to a massive, ominous shadow moving through the cosmos – Unicron, a planet-sized being capable of consuming entire worlds, awakens.

The visuals shift to Earth, where the Autobots, led by Optimus Prime, Bumblebee, and a new human ally (played by John Boyega), are trying to rebuild after the battle with the Decepticons. Peace, however, is short-lived as ancient Cybertronian symbols begin appearing across the globe, signaling Unicron’s arrival. The humans and Autobots alike are faced with a mystery, trying to decipher these symbols before it’s too late.

The trailer then introduces the main villain, Unicron, in all his colossal, terrifying glory. His arrival brings cataclysmic events, with cities being torn apart and entire planets crumbling under his power. His booming voice (voiced by Laurence Fishburne) declares: “I am Unicron, devourer of worlds… and your time has come.” The stakes are higher than ever as both Autobots and Decepticons are forced to confront the cosmic entity, who threatens all of existence.

Megatron (voiced by Hugo Weaving) reemerges, seemingly reformed and willing to team up with the Autobots, but tension brews between him and Optimus. The trailer teases intense action sequences, including massive battles on Earth and in space, where the Autobots face impossible odds against Unicron’s minions and his sheer destructive power.

In a shocking twist, the teaser reveals that Cybertron holds a long-lost weapon capable of defeating Unicron, but it’s hidden in the ruins of the ancient Transformer civilization. The trailer ends with Optimus Prime delivering a powerful line: “We must unite… or perish together.” As the teaser cuts to black, the title Transformers: Rise of the Unicron emerges with the tagline: “The ultimate battle begins.”
