Shortly after reaching the other shore and taking out Skywarp, Prime witnessed the gigantic Bruticus bust out of the Terrordrome and attack everything around him. With Superion gone, Prime knew that there was only one way to stop this rampaging monster, and ordered his Autobots to evacuate the humans while he went looking for the Matrix of Leadership. He soon found that Snake-Eyes was in possession of the artifact, but was under attack from Megatron. Prime attacked Megatron, keeping him at bay while telling Snake-Eyes that destroying the Matrix would kill Bruticus. The ninja complied, only to learn that Optimus had left something out of the story: smashing the Matrix would kill all the Transformers, including Prime himself. Looking at the Autobot leader's body, the Joes knew that Prime had been aware of this, and had deemed it a necessary sacrifice to save the humans. The Iron Fist
A second Target-exclusive redeco of the Voyager Class Optimus Prime toy, the gray molded pieces were recolored beige-grey, and multiple parts that were previously molded in blue and red (the chest, shoulder pads, and leg interiors) had their mold colors swapped, with extra paint operations to make up the difference. As such, the toy has very few visual differences from the regular release of the sculpt, in a "doing things differently to achieve a very similar end result" sense. This version was only available in a pack with an unchanged Deluxe Class Bonecrusher.
When Sergeant Hound apprehended a criminal going by the name "C-81", rumors that the prisoner was in reality a "Megatron" that had gotten past the TransTechs' security procedures piqued General Optimus Prime's interest. Though Cheetor assured him that it was impossible for a "Megatron" to have been allowed in Axiom Nexus, the General's concerns did not fade. More pressing concerns took over, however, when the entirety of Axiom Nexus, and nearly all of the TransTechs suffered a sudden shutdown due to a surge in the Global Net. General Optimus Prime tasked Bruticus with keeping guard over the prison while he and Hound went to investigate the source of the surge, the planet's core.
Part of the first wave of TakaraTomy Lost Age: Movie Advanced toys, this Japanese-exclusive redeco of 2007 Transformers Protoform Optimus Prime is given a Generation 1-styled color scheme (which is also based on his appearances in IDW's Transformers: Foundation comic-book mini-series). Protoform Optimus Prime transforms into his "entry" mode. This mode somewhat resembles a cybertronic truck, with false wheels sculpted onto the sides, and Optimus Prime's trademark windows in front. His now-blue flame decoration piece fits to the back of the "vehicle", creating the illusion of a flaming comet's tail (Not sure if this was mean to represent his jetpack blast effect or his atmospheric entry heat effect, which is for no reason: entirely blue instead of hot red). The bottom of the vehicle has small wheels to roll the toy across smooth surfaces.
