Prime would make one further surprise appearance in Dreamwave's Transformers: Armada series. With Optimus Prime having disappeared to an alternate dimension, devastated by Unicron, the Autobots attempted to find their leader. As Jetfire attempted to locate him through Spacebridge links to other dimensions, one of these clearly shows RiD Optimus Prime and Prowl.
Available exclusively from Japanese clothing company A Bathing Ape in 2017, MP Convoy Reissue BAPE Ver. is a trailer-less redeco of the MP-10 mold sporting a unique black color scheme matching the Convoy Reissue BAPE Ver. BLACK of the original G1 toy, with "BAPE's famous camouflage pattern" and an ape head print on the shoulder replacing the usual faction symbol.
Available in a two pack set with Battle Changer Megatron, this Optimus is largely the same as as the single release, with some minor differences. He uses a new "double harness" piece on his torso instead of using two harnesses, leaving more space for his head to grip the neck-post. He also has different windshield decals, and his reds and blues are slightly darker. And, most obviously, he has an additional buildable trailer, though it doesn't really attach to the truck mode in any meaningful way.
Transformers: Tribute Optimus Prime is a redeco of the 2007 Leader Class toy, to commemorate the 10th anniversary of the live-action film series. While the deco's paint mask is the same as the said figure, he features a more saturated blue and red, and chromed feet/front grills which was used for the MA-21 redeco, and he also features chrome on both sides of the stomach. While the Hasbro stock photo shows that his feet are slightly mistransformed in robot mode, the Takara stock photos shows his feet correctly flipped out.
This military-colors redeco of the Auto Roller Dirtbag was planned for late Generation 2 and widely solicited alongside fellow redeco Sargent Hound, but never saw release. Transforming into an "earth mover" dump truck, he has an auto-transforming gimmick activated by rolling his rear wheels; roll forward to go to robot mode, and back to dump truck. A switch on his back end separates the gears of the gimmick, allowing him to roll freely in either mode. In vehicle mode, his missiles can peg onto the front end of the dump-bed for storage. In robot mode, he has a twin spring-loaded missile launcher in his right arm, and a clamping "stun gun" claw on the left.
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.
In the third nexus, Optimus oversaw Ironhide testing Sparkplug's latest invention, the Sun-Pak, a miraculous device capable of fuelling a Transformer for an entire Earth day after being charged for only an hour in sunlight. As the trial-run wound down to an end, the Decepticons suddenly burst into the Autobots' secret underground testing facility, forcing Optimus to decide whether to order a tactical retreat, or have his Autobots fight the intruders despite his troops' low energy reserves. If he chose to stand and fight, he had the additional choice to either make the Autobots concentrate on Starscream, who is leading the charge against the Autobots, or divide his troops' attention onto all of the Decepticon assailants. If Optimus chose to attempt to eliminate Starscream once and for all, the Decepticon Seeker would beg for mercy, forcing Optimus into a choice yet again: accept the snivelling Decepticon's surrender, or continue his attempt to end Starscream's evil once and for all. Accepting Starscream's surrender spells victory for the Autobots, whereas ignoring Starscream pleas ultimately leads to Sparkplug being kidnapped by the Decepticons, necessitating Optimus to send Buster, Blaster and Bumblebee on a perilous retrieval mission while the other Autobots recharge at the Autobots' home base.
Available exclusively from Japanese clothing company A Bathing Ape in July 2011, concurrently with a range of exclusive Transformers t-shirts, "Convoy Reissue BAPE Ver." (コンボイ復刻版 BAPE® Ver.) is a redeco of the original Optimus Prime toy sporting a unique new green color scheme, along with a tan trailer decorated with a camouflage pattern. Both trailer and Prime himself feature the A Bathing Ape logo in place of an Autobot symbol, while the floor of the trailer's Combat Deck mode features new Bathing Ape-themed labels. The figure comes in a recolored version of the original Japanese Optimus Prime packaging.
Ralston marketed many breakfast cereals based on cartoons in the 80s and 90s. One of these was Transformers. The Transformers Chocolate Flavored Cereal was a chocolate-flavored concoction, not unlike Cocoa Puffs, manufactured by the Ralston Corporation. However, the cereal was sold only in some parts of the United States and was short lived. The cereal box had Optimus Prime on its cover. The box claims the cereal had "more taste than meets the eye" and also had the ability to "transform ordinary milk into chocolate flavored milk". There also was a mail-away offer for a Jazz toy. The few boxes that still exist are collectables, (one of which went for $349 on eBay).
The Beast Wars raged on prehistoric Earth, eventually leading to the discovery of the buried Ark sometime after its crash on prehistoric Earth. Megatron, following his namesake's instructions in a desperate gambit, decided to attempt to change history by killing Prime, who was still lying in the Ark in stasis lock. Megatron hoped that this would result in the Decepticons winning the Great War and eventually Predacon control of Cybertron. Megatron unleashed a full-power weapon blast at Optimus Prime's face, near-fatally injuring him. The Agenda (Part III) However, Optimus Primal proceeded to take Prime's spark into his body to protect it from surgical trauma while his injuries were repaired. The subsequent power increase caused by Prime's spark's connection to the Matrix mutated Primal into a large, Transmetal "Optimal Optimus" form. Then, with the repairs complete, Prime's spark was restored, and he briefly activated before sinking back into normal stasis. Optimal Situation
This gold vacuum metallized (save for his black joints, which they were made out of unpaintable plastic) Protoform Optimus Prime figure was featured as a Lucky Draw giveaway (along side similarly gold vac-metal versions of Voyager class Optimus Prime and Protoform Starscream) in the December 2007 issue of TV Magazine. Released in 2008, only 5 pieces were made, making it one of the rarest Lucky Draw figures; the images at right represent the only known photographs of it.
