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.
Once combined, DaiKenzan has three new phrases (spoken in Kenzan's voice), while DaiGekisou has four (in Gekisoumaru's voice). In either combined form, pressing and holding the button activates an additional, longer phrase for their "final attack". DaiGekisou is armed with a scissors-esque "shuriken" made from combining Optimus Exprime's two swords, while DaiKenzan simply wields them separately.
If Optimus ordered his troops to come to the humans’ aid, they found themselves taking part in a struggle in futility, as the entire town was near-weightless, meaning they couldn’t put the humans anywhere where they wouldn’t float away once more. Then, the Autobots heard Decepticons approaching. Helpless in their current position, the Autobots were quickly eradicated by the Decepticons.
