Part of the third wave of Prime Cyberverse Commander Class toys, Nightwatch Optimus Prime is a redeco of Series 2 Cyberverse Optimus Prime, using the faceplate-less head sculpt that is gang-molded with the original head. His blue plastic is now gray, his smokestacks and thighs are left unpainted, he loses the Autobot insignia on his right forearm/door, and he gains yellow paint highlights for his eyes and lights, along with various other minor deco differences. Instead of the original release's cannons, he now comes with a pair of swords, which each have a pair of 3mm posts for wielding/mounting.
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.
Honestly, all the charts were done in Excel. I tried other methods but that was the easiest since all my data was in excel already. They are X,Y Scatter plots with sooth lines – heavily tweaked. Made the lines thicker which makes it look smoother and changed the layout a bit to make it clearer. The Excel defaults are ugly but if you spend enough time tweaking them you can get something passable.
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.
