According to the bio printed in the Transformers Collectors Club magazine, Optimus Prime was a member of the Cybertron Dimensional Patrol, but was abducted by Unicron. It is unknown whether he repainted himself yellow before being abducted or if the recoloration was due to the radiation emanating from Unicron, which has a tendency to recolor Cybertronians.
Produced by the Chupa Chups lollipop company, this small version of Prime is essentially a battery-powered "holder" for lollipops, which fit behind his head and are spun around by a motor that activates when his pelvis is pressed. Prime has articulation in his shoulders, and his fists feature small holes that allow him to hold and store two more lollipops, in addition to the strawberry sucker he comes with. Weirdly, his Matrix compartment is open instead of having the grill front-and-center.
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.
