Optimus Maximus (G1)
| This article is about the Generation 1 combiner. For the Prime battle station, see Optimus Maximus (Prime). For other meanings, see Optimus (disambiguation), Maximus (disambiguation). |
- Optimus Maximus is an Autobot combiner from the Generation 1 continuity family.

The mighty Optimus Maximus was Prowl's last-ditch attempt to protect the world of Caminus—and perhaps the entire galaxy—from Starscream's political machinations. Every Autobot involved in the combination process brings some of their own unique traits to the composite individual that is Optimus Maximus – the dependability of Ironhide, the strategic genius of Prowl, Mirage's cloaking powers, the courage of Optimus Prime and Sunstreaker's... good looks.
Optimus Maximus is the combined form of several Autobots:
| Generations formation | IDW formation | Unite Warriors formation | |
|---|---|---|---|

Optimus can also form Ultra Prime by combining with a more random assortment of Transformers.

Fiction
IDW Generation 1 continuity

After Prowl's first two attempts at stopping Starscream ended in his arrest, he fell back on his contingency plan: roping Rattrap into stealing the Enigma of Combination and delivering it to his cell—just as Ironhide, Mirage, and Sunstreaker arrived to meet with Optimus Prime. Although Optimus tried to stop Rattrap, he activated the Enigma. The five Autobots were exposed to its energy, merging them into a new, combined form. With Prowl in control, the new combiner headed through the unstable space bridge portal, vowing to end the conflict once and for all. You, Me, and the Universe
Devastator was not impressed with Prowl's "upgrade", and made his displeasure clear by clobbering him. Within, the other Autobots struggled against Prowl's analytical personality, weakening the combination and causing them to collapse. Superion and Defensor were forced to help the struggling gestalt against Devastator and Menasor's onslaught. Within the combiner's psyche, Optimus and Prowl finally reached a grudging understanding. As the brawling combiners bounced from world to world, the five separate minds united...causing the reinvigorated combiner to declare himself Optimus Maximus!
The three combiners managed to surround Devastator as they reappeared at Cybertron and tore him apart, reducing him to his components. With both combiners defeated, Optimus Maximus willingly separated himself so that Prowl could be arrested. Since Prowl was now in custody, a saddened Superion mused that Optimus Maximus might never form again. All That Remains
Prowl taunted Optimus Prime after his arrest, stating that their time together as Optimus Maximus meant that a part of Prowl would always exist in Prime's mind. Now and On Earth
Mirage also returned to the Lost Light along with the Protectobots, making any future formations of Optimus Maximus even more unlikely. The Transgressors
The brawl between Optimus Maximus and Devastator unfortunately led the inhabitants of the Metrotitan Carcer to conclude that Cybertronians were conquerors only interested in exploiting other civilizations. The Will of the Few
After Optimus Prime had annexed Earth, Galvatron put forth the idea to Arcee that Optimus' recent shift in attitude was a result of Prowl's personality influencing him due to their time spent as Optimus Maximus. The Medium and the Message
Unite Warriors

In 2021 on Cybertron, a temporarily resurrected Optimus Prime joined with four of his soldiers to form Optimus Maximus in response to the intervention of Megaempress and her 4 Guards. Optimus Maximus proceeded to struggle against the mighty Decepticon combiner, whose onslaught prompted Optimus Maximus to shield Marissa Faireborn and Sue from falling debris. Megatronia Chapter

Toys
Generations

- Sunstreaker (Deluxe, 2015)
- Mirage (Deluxe, 2015)
- Battle Core Optimus Prime (Voyager, 2015)
- Prowl (Deluxe, 2015)
- Ironhide (Deluxe, 2015)
- Rodimus (Legends, 2015)
- Optimus Maximus is a combiner made up of four Deluxe Class figures (Sunstreaker, Mirage, Prowl, and Ironhide) as limbs, a Voyager Class figure (Battle Core Optimus Prime) as the torso, and the usual Legends Class figure (Rodimus) to complete the set, all as part of the Combiner Wars subline. As per the other combiners in the line, any deluxe toy can become an arm or a leg, and each deluxe figure comes with weapons that can become hands or feet for the combined mode. Whether by coincidence or design, all of Optimus Maximus's components are retools of the Stunticons, essentially making him a retool of Menasor.
- Battle Core Optimus Prime has the improved hip joints also featured on the second run of Motormaster. This allows for a more natural pose in robot mode, as well as a more stable combined mode.
Unite Warriors

- Convoy Grand Prime (Multi-pack, 2016-02-27)
- Japanese ID number: UW-05
- Accessories Weapons, 4 Foot/Hand/Guns
- Takara's iteration of Combiner Wars Optimus Maximus is sold in a gift set including all five Autobots (minus the Rodimus mold). He has numerous changes in deco to better match their component's appearances in the Generation 1 cartoon. Like Unite Warriors Menasor, the set also features some minor improvements to the original sculpts, such as improved hip-ratchets for Optimus Prime for increased stability.
- Printed on his instructions is the fifth chapter of Unite Warriors Offshot. Undocumented in the instructions, Unite Warriors Optimus Prime's chest can attach Adventure Runabout (Or his mold mates Blackjack and Rodimus) on his combined mode chest.
- The giftset also includes a collector commemorative coin when purchased in select retailers outside Japan.
Notes
- In his first comic appearance, Optimus Maximus appears with the red and blue torso colors of the original Combiner Wars Optimus Prime toy. The subsequent issue, meanwhile, swaps out the blue for Battle Core Optimus's white and gold parts whilst retaining all the red, presumably as a compromise to promote the new toy whilst not completely ignoring the previous installment.
- Maximus's limbs call to mind Energon Optimus Prime's super-mode, with a white limb (Prowl), a yellow limb (Sunstreaker), a blue limb (Mirage), and an orange limb (Ironhide... kinda). TakaraTomy would take advantage of this when releasing their "Convoy Grand Prime" set, putting the limbs in the standard configuration of the Prime Force drones for art and stock photos and fully painting the Energon-inspired sculpting on Optimus's torso mode.
- Optimus Maximus also shares his limbs with Betatron.
