Forced to admit that Crocea Mors didn't feel right in his hands—no matter how he held it—Jaune Arc struggled to overcome this obstacle through the insane idea that Aura could become more than just the armor that protected him. Barriers broke as he pushed past the limits of what Aura was capable of, creating and forging his very own weapons from the manifestation of his soul.

Optimus gets captured by dragon slayers who use anything they can from a dragon, even forcibly breeding them for eggs. They chain him to the floor of a cave, and he quickly finds out that his breed's worst enemy is in there with him.

Post TF:P Season One finale: Megatron has regained a long lost ally in Orion, and will stop at nothing to prevent the restoration of Optimus. Unwilling to abandon their Prime, the Autobots grapple with the loss of their leader and struggle to do everything in their power to get him back.

It has always been a well-known fact that Optimus is the perfect leader of the Autobots - both idealistically impossible and spotless at the same time. But in truth, none of the history books got it entirely right. This is an actual recollection of what might or might not have occurred. With every cards revealed on deck, the role of judgement is yours to proclaim.

G1. Starscream is given a choice other than execution after the end of the war: rebirth through Vector Sigma. Reformatted as a sparkling, he's taken in by Optimus and Ironhide as their son. Too bad Ironhide isn't too keen on the idea. OP/IH, future SS/SF

It's not as simple as 'mech turns into vehicle.'

Optimus writes a list of things the autobots aren't allowed to do. Humanformers.

After finding his friend and saving her from a mysterious mech from the dangerous parts of Iacon, Optimus catches the eye of the mech that is a Incubus. He plans the possess his body and become a part of Optimus, so once he does that, Optimus will never be the same ever again.

When a meditation with the Matrix of Leadership reminds him of the Prime's priestly duties, Optimus decides to hold the Rite of Prima's Blessing: an ancient ritual devoted to connection, unity...and the Prime's submission to all Cybertronians.

After letting slip a personal detail, Optimus Prime finds himself becoming the object of pursuit.

Bumblebee's crush on Optimus Prime has gone nowhere... until now that the little mech has gone into heat. Tradition dictates that the Prime has first rights to each and every Autobot's reproductive ability. Finally given a shot at the Prime's berth, Bumblebee's ecstatic. Size differences and happy stickiness ahead!

Story #2 of the "Prime's Right" series. Mirage goes into heat just days before the launch of the Ark and the fated mission to find a new source of energy. Pleasantly sticky.

Smokescreen abandons his post one night at the base and Optimus decides to punish him using unusual methods.

Jazz: he is beauty, he is grace, he is staring at that bumper yet again. (Pt. 19: Well, he's not dead yet.)

Optimus's reproductive protocols get in the way of Megatron trying to beat the scrap out of him, and it turns out to be a lot more difficult trying to fight a mech that wants to clang you, rather than a mech that wants to kill you. G1, Sticky, Dub Con.

Soundwave has fought in (and lost) Mortilus' Games as part of the Festival of the Five for twelve Festival cycles. This time will be different. (Part of the Festival of the Five collection.)

The war is over. Cybertron lies in ruins and Megatron, like many cybertronians, is in stasis. Optimus Prime was supposed to be reformatted to allow for peace as the remaining cybertronians rebuild. Except he remembers and he is in no mood to deal with the mechs who betrayed in. Unfortunately, fate might not let him ignore his duties. He was chosen for the reason after all.

Optimus X Megatron...Had to write fluff. Also can't think of a summary.

Optimus has long desired a certain Mech and when fate gives him said Mech, nothing will stop him taking what he wants. Warning for dub/non con and sexual scenes. Will include other Autobot/Decepticon pairings but not always the ones you'd expect.

It was probably Wheeljack's fault. It was usually Wheeljack. But knowing the culprit helped very little Optimus. He longed to be back on his wheels. Now. Before Megatron ruined them all.

Since the Transformers landed on Earth, the war has died down, making a basic programming they have activate, a programming called a Heat Cycle. This program helps Cybertronians create life, but Optimus Prime doesn't think its safe yet and Megatron thinks sparklings are weak. Can they control this insane time or will it end in disaster? (Lots of Pairings in here. Sparklings! Smut)

Optimus walks away on Megatron in the middle of a battle. Its over.

A collection of oneshots from G1, Prime, Bayverse, and Animated. 112: Gestalt, IDW, Optimus Prime and Optimus Maximus and Megatron. 113: Band of Brothers, G1, Starscream and the Dinobots. 114: Bun in the Oven, G1, Megatron and an Ensemble.

Optimus is back and questions Grimlock...if he still remembers him... base off of TF Robots in Disguise

Optimus has been training for years with Micronus, but he doesn't know what until the Primes agree to send him back to face the darkness returning.

The Autobots thought they could trust the gov, but not everyone in the government was well meaning, it turned out. Now, feeling betrayed, the Autobots take Jack, Miko and Raf, going to the only ones they can turn to...The Decepticons. There's one thing Megatron can't stand: The willful harm of sparklings. And sadly...That is why the 'Bots must turn to the 'Cons now. ON HIATUS!

Optimus has Megatron in his clutches, and he's not about to let a chance at revenge slip through his digits.

G1: Optimus wonders if people really like him or if they're just nice to him because he's the Prime. He decides to ask Prowl about it.

Optimus Prime is, in many ways, the Prime of rebirth, renewal and resurrection. For Cybertron, it's people, and many other things... and his secret dread is that there's a reason he just can't seem to stay dead either. Mildly AU in a 'Autobots as revolutionaries' way.

Recent intel from the Nemesis tells Optimus Prime his past with Megatron may have produced results. Ratchet doesn't know what to think about all this. Mechpreg.

Megatron discovers why Optimus is so stoic and sets out to change it. Huge amounts of fluff, AU and OOC. A companion one shot to "Behind Closed Doors"

Megatron captures Optimus but doesnt want to kill him? no he wants to make the Autobot see the truth, but Megatron get's more than he bargained for and it's only gonna get colder as a new enemy surfaces. Will Optimus listen to Megatron's reasons for starting the war? Will Blitzwing teach Bumblebee how to fly? Will someone please get Sari a heater SHE'S FREEZING!

In the wake of the destruction of Praxus, Prowl is forced to confront his own volatile emotions. But Barricade is out for revenge, and he will see to it that Prowl suffers the same way he did...Sequel to I'll Be There. Jazz/Prowl, Bluestreak, & Barricade

Optimus released the Matrix. He lost his memories and reverted to his pre-Prime state. What happened to him on the Nemesis? (Generally told through Orion's optics)

TFA: Set during Megatron Rising After the battle with Megatron, Optimus Prime had been feeling odd, his spark behaving strangely. Never could he have guessed what that beam strike could have done or what it would leave him with. warning: Mpreg

Hope arrives from an unexpected source with the loss of Optimus Prime to the Decepticons. "Transformers: Prime" universe. IronhidexRatchet, other various future pairings.

Ultra Magnus been thinking about Optimus...and something comes up... Optimus/Ultra Magnus rated M

TFP At the end of One Shall Rise (Part 3) Optimus has done it. With Unicron now defeated, all seems to be at peace again. But a shocking consequence of the battle reveals itself and the tides of war change for the better or for the worse. And the Autobots now have to decide how to deal with the outcome and if 'he' can be trusted.

The great and mighty Optimus Prime flew down the Well of Allsparks, glad to finally rest.

Will Lennox here. Optimus is having us write down rules, humans and autobots alike.

The current stellar cycle wasn't one of the best in recent memory. Nearly getting himself killed on Antilla, and getting saved at the last minute. Dying would've been a relief. Ultra Magnus' luck, so far, was holding. But fate sees fit to give him back someone he thought he'd lost-his brother, his split-spark twin, Optimus Prime. Optimus PrimexUltra Magnus. Twincest.

TF Prime. Optimus goes to extreme measures to stop Megatron once and for all

"What is this?" Jazz straightened, glancing at the bowl, his grin still in place. "Tha' Prowler," he said, returning his gaze to Prowl's "is ah Betta splendens. Also known as ah-" "Siamese fighting fish or a betta fish." Prowl finished. "I know what it is, why is it on my desk?" cute oneshot that popped into my head. G1 Universe. Prowl centric. Title is scientific name for a betta

After Optimus Prime merges the All Spark with the Matrix and sacrifices himself for the rebirth of his race, Primus decides to give him one more chance as Orion Pax. Though his memories of Optimus are few and cloudy. Megatron decides to help Orion regain his memories and hopes that he and his once almost bondmate could start anew on a reborn Cybertron.

Before he was a Prime, before he was Optimus, there was Orion Pax, a clerk turned soldier. He would do anything to stop his older brother, Megatron, and his growing army of Decepticons. An epic story full of battles, betrayals and hardships. The journey of becoming a Prime, a hero. My first fanfic. DISCONTINUED.

At the start of the great war between Autobot and Decepticon, the last, best Prime is found in an unwitting Iaconian archivist named Orion Pax. But what if Orion Pax survives a horrific procedure that usually killed all other Matrix bearers? How would it affect him to see another version of himself on the battlefield? MxM, Major AU,

Set in the original G1 animated series. What happened to Optimus Prime between his exploitation by the Quintessons and his return to combat the Hate Plague? My attempt to explain continuity problems.

G1/AU The war is over and Rodimus Prime is slowly working to bring the Autobots and Decepticons back to one people. Optimus and Skyfire are making the most of their new free time together with a few surprises in store for all. slash, mpreg

His brother turned his gaze to him, expression no longer neutral but one of contemplation. There was a measured silence, as the ramifications of the situation were being processed. Finally, Optimus folded his arms over his chest and asked, "What is the last thing you remember?"

When a new Prime ascends it is tradition for him to replace the entire command staff. Optimus is ignorant of this and it is Prowl's duty to enlighten him. Doing so is going to reveal more than the Praxian wishes. (From the Ashes 'Verse)

Megatron drafts a peace treaty to end the war. Poor Optimus didn't catch the fine print. Crack galore. Meg/Opt.

The third, and final, installment of the Optimus/Megatron trilogy. Optimus has had run-ins with Megatron before, but has the Decepticon changed his ways? Has he decided to let Optimus steal his heart and turn him away from evil?

In which all is not well in army or command, and Optimus has no choice but to force two mechs that despise each other to work together for the Greater Good. Prowl and Jazz will either learn, or kill each other in the process. Neither mech is sure which is the better option..

G1, crack. Talking mascots, pretty skirts and sparkles abound: Prowl and the Pretty Sailor-Suited Autobots are here to protect and serve. Earth will never be the same. Just stay right there and we'll show you!

The Decepticons have won against the Autobots and turned the only hope for Earth into a Decepticon. Optimus is no more One-shot, bit of slash in it Yes I want the cons to win for once

G1. When an unprecedented event causes a radical alteration in the programming of every Transformer, the Autobots turn against everything they held sacred whilst the Decepticons stand as the only hope left for humanity.

Sequel to 'The Scotsman in Me', the Kilt's back and this time it's not just Magnus being effected by it. Slash! Prime/Magnus, Ratch/Hide with some other's thrown in for good measure.

G1 Au Prowl/Jazz Optimus comes up with a unique way of resolving political conflicts. Prowl and Jazz enthusiastically follow suit.

Optimus Prime systematically locks 'bots up together. Because if they aren't going to get together on their own, he's going to shove them in the right direction. Multiple pairings. Covered Prowl/Jazz and Inferno/Red Alert so far. Probably never to be completed.

Finally, after eons of separation, Optimus is reunited with his bond-mate as they share their first night together since the exodus. (for Rainbow-Velociraptor, because I adore her and I think she deserves a gift fic with her otp in it! This is for you bebe, feel better soon.)

Magnus loses a drinking contest against Wheeljack and must suffer as a result, well one mech's suffering is another's entertainment. Random and not serious! Two maybe three shot

(G1-cartoon continuity) Megatron's hunger for power is only outshadowed by his hunger for a tidy base. Meanwhile, Optimus Prime reaquaintences the Autobots with an old Cybetronian tradition - spring cleaning. Much mayham ensues.

AU. Nemesis realizes he made a terrible mistake. One shot

Prequel to my one-shot 'A week in the life of Galvy'. How both Cyclonus and Optimus received their injuries. Both Megatron and Galvatron wonder why it is always their sparkmate's that receive the most serious injuries. Rated T because I'm not sure whether it fits under K so T is the safe bet. No language. Cyc/Magnus/Galvy Megs/Oppy

Ultra Magnus finally makes it to earth and finds Optimus among the ruble. slight Ultra Magnus/Optimus Prime. for Fangirlsrock (on Tumblr)

This is a gift to Murr-Miay. G1-ish: A "mysterious" Decepticon from comes from the future, craving Optimus' love and Megatron who also wants the Prime. Optimus is soon at the center of the two's affections and will eventually be forced to choose... Megatron? Or... Galvatron? Mushy, fluffy and sticky! Hooray! MegatronXOptimus and GalvatronXOptimus pairings.

Giftfic for Lyricality. Yet more fix-it fic for Season 2. With Orion Pax on their side, the Decepticons have won the war. Megatron exults in his victory - and in his new consort. But Orion is plagued with doubt, and his recharge is filled with nightmares. M for sticky, dub-con, and Megatron being a horribly manipulative bastard.

Sequeal to Galvatron's sparkday. Its Oppy's sparkday this time and its his turn for a surprise!

Skyfire has been pining for what many Autobots have. A lover, a mate. But the majority still don't fully trust him. Only one mech always has and he's caught the flyer's optic. Now, it's a matter of obtaining the unobtainable. sticky, slash

Optimus isn't quite sure what he's done, but Prowl is there and he's ordering him and his finger is pointing, so there is only one thing the Autobot leader can do... Just a cracky little oneshot.
