My idea was the future, Cybertron is neo-noir cyberpunk cityscape that covers the entire globe and Pax Cybertronia has been in place for years. The new generation is sleek, advanced and have no idea what war is. They even replicate organic features blurring the line between the two (think BW eating food) this Cybertron isn’t anti-organic but they have a chip on their shoulder.
Then you meet Optimus, going by his old name for anonymity, old, out of place, lonely and very low, he works in the data archives, doesn’t rest often and is mocked for his out of place alt-mode, the Earth truck. He gets his morning coffee equivalent, gets supplies, living a mundane life, very few of the G1 cast are shown. Notably his only “friend” is a xeno botanist who recognized him and is a bit of a hero-worshipper, it’s Botanica and she too is a mocked outcast, for her interest in the organic.
It’s his “Dark Knight Returns” because he steps in when he sees someone being harassed by Predacon thugs, gets the shit knocked out of him, but it reignites the fire. He has no matrix anymore, isn’t the top of the food chain and he’s kinda like Kup in that aging correlates to mental state/hardware updates.
He makes a public return during a highway chase with Predacons who launched a heist at a Maximal R&D facility, doing the iconic moves and sparks an inferno in Cybertronian media, their equivalent of Abe Lincoln got in a crazy car chase, was launching himself in the air and being his usual action hero self. He reclaims the name, Optimus Prime is back.
It pivots to a Bladerunner-esque detective story where Optimus and his new friend Botanica (Carrie Kelly equivalent) look into who’s sewing division and remaking the factions in new forms (Maximals/Predacons) all while getting to know this older Optimus.
He shut out the world due to the sense of purposeless after the war, the world doesn’t make sense anymore and the “war” is shown to be the cheerful Sunbow-like days. It’s meta-tackling the innocent early days and the cynical Bayverse future.
Eventually it’s revealed the Tripredacus Council are splinter Decepticons trying to keep suspicion off themselves while they reverse-engineer Galvatron’s time travel tech. They’re stand-ins for the G1 cultists.
Optimus sends Botanica to get reinforcements, to get her out of the way and launches a one-man assault on the facility, fighting Predacus and doing his “Logan” last stand.
Damaged, he sees the time drive and tempts him with a world that is familiar, with friends, where he’s “the man” and it makes sense. He rejects it and destroys it, the blast burns him and he’s down bad, dragging himself out of the facility he’s found by Botanica, who throughout the story becomes a sort of protege and almost daughter, she’s written like TF: One Orion Pax.
He sits down on an overlook, leaking Energon, broken beyond repair, Botanica begs him to get up and Optimus just removes the iconic mouthplate with his one remaining arm and smiles. This Optimus who is implied to be G1 Sunbow Optimus smiles, visibly for the first time since War Dawn and tells her it’s okay. Optimus spends his last moments comforting someone else and dies quietly overlooking his flawed homeworld, no grand speech, no orchestra or free fall into the planet, an old man dies and the Great War’s last combatants die out in one night.
Botanica cries, a feature the new generation possesses then, the planet snows, for the first time ever and her eyes turn blue momentarily and it focuses on the blood splatters Optimus left, the faintest bit of plant life is growing out of them, Optimus saved the future and that last bit of Matrix-enfused Energon in his body is starting the next evolution of the Transformers.
The stage is set for Beast Wars and adds some context to Beast Machines.
A new Tripredacus Council takes the place of the old one and plays ball with the Maximals, the transwarp tech has to be recreated, the fear of time travel isn’t stopped but it is delayed and exposed to the greater populace. Optimus is put to rest in a massive ceremony, a Maximal cadet is in attendance and inspired by his hero, renames himself. A pissed off Predacon sees the vaccum and begins scheming.
Throughout the story, Optimus rediscovers his hope and reverts from stoic and cynical Prime/Bayverse Prime to the one-liner dropping and more…. cowboy-like 80s version. Accepting death with a smile and an act of compassion, saving a future he didn’t particularly like because it was the right thing to do.
