Back in the 60s, Hasbro was commissioned to play down the negative stigma surrounding US soldiers fighting in the Vietnam War. The result was four, 12-inch tall dress-up dolls featuring realistic camouflage fatigues and weapons of the time. The figurines represented the Army, Navy, Air Force and Marines. There was no real storyline at the time which limited the allure of the toys.
The largest Action Master set, this incarnation of Optimus Prime is a non-transforming action figure which comes with the "Armored Convoy", a large, heavily armed tractor trailer. The cab of the truck transforms into a small jet that can seat one Action Master figure, while the trailer itself converts into a larger battle station with turrets that several Action Masters can man. The sculpt of the Prime figure itself is closely based on his character model, albeit with a coloration that seems to have been based at least partially on the small robot form of his Powermaster body.
When Sideswipe was accused and convicted of destroying the Nova Suspension Bridge, Optimus was infuriated that one of his own Autobots could commit such a heinous act. Optimus was tasked to hunt down and deactivate Sideswipe, though the task proved to be easy as Sideswipe did not run, hide or resist. After Optimus had deactivated Sideswipe, he was approached by Prowl, who pointed out that Sideswipe's actions made little sense, as he had committed the crime in broad daylight before many witnesses. Agreeing that the Decepticons might be behind the situation, Optimus allowed Prowl to take a team of Autobots to Carob Island to clear Sideswipe's name while Optimus and Jazz stayed behind to continue working on human/Autobot relations. Prowl returned with evidence that it was indeed a Decepticon-controlled clone of Sideswipe that had committed the crime. Optimus then presumably reactivated Sideswipe when his name was cleared.

When the narrative begins, we’re taken to Cybertron, where a narrator tells us of the battle between the Autobots and Decepticons, a war fueled by the Decepticons’ desire for total domination. We’re told, “The Autobots, on the verge of extinction, battled valiantly to survive.” Then, two Autobots in robot form climb out from under a grate, armed with a bunch of energy conductor sticks: Wheeljack and Bumblebee. Wheeljack transforms into a Cybertronian vehicle, then Bumblebee loads the sticks inside him. Bumblebee is so relatively small that he remains in robot form and hops inside Wheeljack for a ride, rather than transform himself.
The first Generation 2 Optimus Prime toy was largely identical in sculpt to the original release. However, his trailer was cast in black plastic, with the original blue and silver striped sticker replaced with a red and silver one that had "Optimus" in large block letters on it. The trailer also featured a soundbox attachment with a sculpted Autobot symbol on the front. The soundbox could activate a truck engine noise, a laser gun sound effect and a (badly) garbled voice that said "I am Optimus Prime!". This soundbox could also be attached onto Optimus Prime's back and be used as a sort of backpack.
Prime would make one further surprise appearance in Dreamwave's Transformers: Armada comic series, although it would not be the Prime of Dreamwave's first series. When the Optimus Prime of the Armada universe disappeared, pulled into another dimension by the power of Unicron, the Chaos-Bringer sent something back in his stead: a nearly dead Optimus Prime from that universe, who warned the transformers of Unicron's coming into their universe before dying.
