In the animated series, Optimus is able to fire short-range optic blasts, project holographic maps, and deploy hydro-foils, designed by Wheeljack, to traverse bodies of water with ease. In the animated series, Optimus was also given the ability to retract his right hand unit and replace it with a glowing axe. Across the assorted continuities of the original Transformers universe, there have been various interpretations of Optimus Prime. One of Prime's most notable characteristics over all continuities his unswaying commitment to leadership by example. The animated series's version of Optimus Prime is depicted as a straightforward, wise, and upbeat battlefield general. Additionally, the animated series's version of Optimus dislikes rap music, putting him at odds with music-loving characters like Blaster and Jazz. In the Marvel Comics series, in addition to these characteristics, Prime is secretly plagued by self-doubt and a conflicted sense of pacifism that often makes him an extremely reluctant warrior.
Optimus Prime appears near the end of the Decepticon Campaign. Sam and Mikaela inform Optimus that all the Autobots were defeated by the Decepticons. Optimus proclaims that they sacrificed their lives to protect the Allspark, and their sacrifice will not be in vain. Leaving Sam and Mikaela in a safe place, Optimus faces Megatron, but is defeated. Weakened and damaged, Optimus crawls to reach the Allspark. However, Megatron attacks Optimus with his chain-flail, killing him.
Optimus Prime appears in the Transformers live-action film series as the leader of the Autobots and one of the main protagonists. In the first three films, he is able to transform into a conventional Peterbilt 379 cab, rather than the cab over design of his original Generation 1 body. In Transformers: Dark of the Moon, he gains a first generation-style trailer form before changing into a 2014 Western Star 5700 Concept. Also straying from the G1 design, Prime's vehicle mode is now decorated with red flames painted onto a blue body à la Rodimus Prime, his Generation 1 successor. The reason for the change was due to Director Michael Bay's decree that mass displacement does not occur when they transform, requiring Optimus's vehicle form to have more mass to achieve the desired size in his robot form.
Optimus appeared in the 2008 BotCon voice actor play "Bee in the City", voiced by David Kaye. In this story, Professor Sumdac attempts to create a teleportation system to get the Autobots to Cybertron, but an interaction with Sari's key ends up transporting Optimus Prime, Bumblebee, and Sari to Transtech Cybertron. There, they met Flareup and are detained by Shockwave. Bumblebee teams up with Beast Wars Megatron to free his comrades, but must then stop Megatron from taking the key for himself. Afterward, the Autobots and Sari returned to their own dimension.
If Optimus ordered his troops to come to the humans’ aid, they found themselves taking part in a struggle in futility, as the entire town was near-weightless, meaning they couldn’t put the humans anywhere where they wouldn’t float away once more. Then, the Autobots heard Decepticons approaching. Helpless in their current position, the Autobots were quickly eradicated by the Decepticons.
