Main Characters from Transformers One

1. Orion Pax (Optimus Prime)

Voiced by Chris Hemsworth, Orion Pax starts as an ambitious Energon miner on Cybertron, content with his role but driven by a desire for a better future. His life changes when he discovers the corruption at the heart of Cybertron’s leadership. As his ideals grow, so does his reputation among his fellow Cybertronians, ultimately leading him to wield the Matrix of Leadership and transform into Optimus Prime. [1]

His deep friendship with D-16 (Megatron) takes center stage, with the two initially working together toward change. However, as Megatron’s thirst for power increases, Orion finds himself at odds with his former ally, igniting a war that will define the fate of their world. Optimus Prime’s leadership is tested as he battles not just the Decepticons, but also the burden of responsibility and the price of standing for justice.

2. D-16 (Megatron)

Brian Tyree Henry lends his voice to D-16, later known as Megatron. Initially, D-16 shares the same vision as Orion Pax, believing Cybertron is in dire need of reform. However, his approach is far more aggressive, and he begins to see force as the only means of achieving true order. Influenced by historical texts about Megatronus Prime, he takes on the name Megatron and forms the Decepticons, believing Cybertron must be ruled with an iron fist.

His transformation is a slow but inevitable process, fueled by betrayals, manipulation, and Sentinel Prime’s treachery. His evolution into Cybertron’s feared warlord is both tragic and terrifying, as he turns against those he once called friends, embracing his destiny as Optimus Prime’s most formidable rival.

3. Elita-1

Scarlett Johansson voices Elita-1, a powerful warrior and leader who stands beside Orion Pax. As a strategist and fighter, she plays a key role in early battles on Cybertron, advocating for peace but willing to fight to protect her people. Her intelligence and combat prowess make her one of Cybertron’s greatest warriors.

Elita-1 shares a deep connection with Orion Pax, offering guidance and perspective as he struggles with leadership. She also spearheads several missions against Sentinel Prime’s forces, proving herself a capable leader in her own right. As the war escalates, her determination to preserve Cybertron’s integrity leads to sacrifices that define her role in Transformers One.

4. B-127 (Bumblebee)

Keegan-Michael Key portrays B-127, a lively, talkative Autobot before losing his voice. Originally a garbage incinerator worker, he yearns for adventure, often placing himself in dangerous situations for the thrill of discovery. His assignment as a Cybertronian scout allows him to prove his skills, and his unwavering loyalty to Orion Pax cements his place in the Autobot resistance.

B-127’s transformation into Bumblebee is one of the most heartfelt moments in Transformers One, as he proves that courage and heart matter more than size and strength. His rivalry with Starscream, his lighthearted humor, and his unwavering dedication to the Autobots make him a fan favorite.

5. Sentinel Prime

Jon Hamm voices Sentinel Prime, the once-revered leader of Cybertron who ultimately succumbs to power and ambition. Believing Cybertron’s survival requires strict control, he secretly allies with the Quintessons, an ancient and mysterious race seeking dominion over Cybertron.

His manipulation of Cybertron’s High Guard allows him to maintain a facade of benevolence while plotting behind the scenes. Sentinel Prime’s betrayal is a turning point in the film, as his deception fractures Cybertron’s unity and accelerates the war between the Autobots and Decepticons.

6. Alpha Trion

Portrayed by Laurence Fishburne, Alpha Trion is one of the original Primes, a guardian of Cybertron’s history and a mentor to future leaders. He holds deep knowledge of the Matrix of Leadership, the workings of transformation cogs, and Cybertron’s ancient past, making him a critical guide for Orion Pax. Unlike the war-hardened fighters around him, Alpha Trion relies on wisdom and diplomacy, hoping to steer Cybertron away from conflict.

7. Starscream

Steve Buscemi voices Starscream, the ambitious and cunning former leader of the High Guard. Once a loyal defender of Cybertron, his thirst for power leads him to betray his comrades and align himself with the Decepticon insignia. Starscream is a master manipulator, often shifting allegiances to benefit himself, and he constantly challenges Megatron’s authority.

His ability to strategize and strike when least expected makes him a formidable figure in the Decepticon hierarchy. Starscream’s skill in aerial combat and tactical deceit allow him to gain power, though his own ambitions often put him at odds with his allies.

8. Vector Prime

A legendary Prime, Vector Prime is one of the Thirteen Primes, an ancient being tasked with preserving the balance of time and space. His knowledge of Cybertron’s history surpasses even Alpha Trion’s, as he has witnessed the rise and fall of civilizations across eons.

Though he does not engage in direct combat as often as other warriors, his ability to manipulate time rifts and foresee potential futures makes him an invaluable asset in the war’s unfolding events. His understanding of Cybertron’s true origins helps the Autobots realize the stakes of their battle against the Decepticons, influencing their long-term strategy.

His resilience and sheer firepower make him an essential frontline fighter in the battle against the Decepticons. Ironhide thrives in combat, leading defense missions and ensuring that key Autobot strongholds remain secure.

His gruff personality and no-nonsense approach to warfare make him a tough but respected figure among his comrades. Though he sometimes clashes with more strategic thinkers like Prowl, his brute strength and battlefield experience often turn the tide of battle in favor of the Autobots.

As the chief medic of the Autobots, Ratchet plays an indispensable role in ensuring the survival of his comrades. More than just a healer, Ratchet is a genius in Energon flow management and Cybertronian physiology, often developing innovative medical solutions under extreme battlefield conditions.

His ability to repair even the most damaged Autobots allows the resistance to keep fighting, making him a key figure in sustaining the war effort. While he prefers not to engage in direct combat, he will fight if necessary, proving his loyalty and bravery in the heat of battle.

A tactical genius, Prowl serves as the Autobot’s chief strategist, ensuring that every mission is planned with precision. As one of the most disciplined Autobots, he upholds strict adherence to logic and tactics, analyzing enemy movements and developing countermeasures against the Decepticons.

His cool demeanor under pressure allows him to make tough decisions without hesitation, making him an excellent field commander.
