Is this referring to Prima, Megatronus, or Solus? The answer is yes because the real answer is that all three are beautiful and badass lol

[seraphim-seeker]

I sometimes like to think about when Sentinel has Megatronus’ t-cog that his spirit haunts him. Tronus never says anything though, he just looks at Sentinel. Even when Sentinel asks him what he wants and why he won’t leave, have never says a word. He just looks at Sentinel, not really with much anger, more of disappointment and betrayal. 

But when Dee takes his cog to become Megatron. Megatronus does speak to Megs and even he tries to convince Megatron the choice his making isn’t wise. Alas, it falls on deaf ears.

In the end, Sentinel ended up on a pile of mech all poof up like a spooked birb going :(

The Primes were expecting a glorious battle of epic gladiatorial skill but they ended up watching every gladiator in the city play 'catch the birdie' and failed and they have to congratulate him cause he's technically the winner

All the defeated gladiators in a pile and only Sentinel was on top of them, more confused than before with the same expression.

Zeta Prime: Uuh.. Didn't expect that.

Prima: I like this new gladiator, can we keep him?

Zeta Prime: Prima, should we just announce the winner-

Prima: Let me keep him, Zeta…? He looks like a little bird. Please! Pleeease! Looks at him with a puppy dog ​​look.

Megatronus: I think you better accept, Zeta..

Zeta Prime: Ah.. OK! OK!

Prima celebrates his victory as Zeta announces the winner.

Sentinel: How did i got here in the first place..?

Do you hoard things?

No.

I think the Primes would've gotten into actual fights over who got to breed Sentinel while he was in heat. I just think Onyx and Megatronus would've gotten into aerial brawls while trying to chase down their beloved assistant to relieve him of his poor state.

Sentinel would've found it hot that whichever won kicked him out of the air to fuck him in front of the others. Might be the only thing he missed about them, as much as he undoubtedly loved getting dommed by Arachnid

EATING THIS OMNOMNOMNOMNOM DELICIOUS

I can definitely see the Primes fighting each other over Sentinel because he’s just so small and cute and pretty and has a superb valve and smells so damn good in heat!

And the only way Megatronus ever loses is if he takes pity on his rivals and allows them to win. Unless it’s Solus. She beats his ass and he likes it.

Ok so we all know that dee’s favorite prime is megatronus but what about you? Who’s your favorite?

My favorite Prime? Zeta Prime, of course! Megatronus was awesomely powerful, and I know Sentinel has done an amazing job keeping the Quintessons at bay to keep us all alive while he searches for the Matrix of Leadership, but Zeta was the most noble and selfless of the Thirteen, which is why Primus gave him the Matrix. I wanna be just like him!

Thinking about TFOne setting Skystar AU pre-Sentinel betrayal like many cycles before it happened, where Skystar are going through the steps of the Conjunx Ritus and Starscream’s Act of Profference (the step/act where you give the other a gift) is basically building a new home for them to live together. Not just buying/renting a new apartment in Iacon, but one made from the ground up or more accurately carved out of the natural rock stalactite, it’s still underground a little on the edge of the city but closest to the surface. And imagine the reason Starscream chooses this location to build their new home is because this specific stalactite has a natural ledge that at that angle when you look up even underground you can see the sky and stars. It’s their spot. The place they would sneak away to when they were still studying together to become scientists and continued going there when they became lab partners working together. A place where no one else could find them to stargaze and look out at the vast sky full of possibilities and late night discussions about new worlds just waiting to be explored. And even if Starscream is now leader of the High Guard and not a scientist anymore the ledge is still their spot they visit. Thinking about Starscream being very Extra about his gift cause he’s like ‘I’m going to make my gift so good that there’s no way Skyfire will back out of being my conjunx!’ (I’m pretty sure Starscream could just give him a cool looking rock and Skyfire would say yes to marrying him lol)

Now also imagine that he also hand-makes their new berth for their home himself, a large berth specifically made to fit someone of Skyfire’s size which has always been a hassle for Skyfire having to deal with finding one he fits in comfortably or often needing to duck to fit into doorways. But this new place is made specifically to fit his size in its entire construction meant to show how much thought was put into making this a comfortable home for the other. And okay maybe the berth was mostly made by himself with some help cause i think it's funny if Starscream goes 'I totally know how to do this on my own' and then it cuts to a scene that's basically when you're trying to horribly put together IKEA furniture, I'm just imagining Starscream going 'I've built a [insert complicated science thing here] before! A berth should be easy!". It was not, especially the fancy one he has in mind.

I like to think he goes to Solus Prime for help on how to construct the berth since she is known for forging and creating/building things so he's like 'I need an expert and also the best for my Sky pls help I've lost count of how many times I've injured myself trying'. And Solus is both amused and nostalgic because I like to think she built the berth her, Megatronus, and Prima share because finding a berth that fits all three is impossible unless it's custom made considering Solus and Prima are pretty big/tall already and Megatronus is HUGE so fitting all three in one berth means that thing needs to be very roomy and big (yes my ass ships all three together, noblefallenforge my beloveds lol). I also like to think that Solus definitely could have hired/commissioned someone to make a custom berth but she's like "but I could make a better one with my skills and this is for my conjunxes so it has to meet my incredibly high standards of construction" so chose to do it herself. Solus to Starscream going "I got you bestie don't worry. I understand the struggle of having an extremely tall and big conjunx lol". They bond over the amount of berths they've accidentally broken with their respective partners. So Solus guides him on how to build the berth he has in mind and it turns out beautifully. The berth's foundation is built directly into the very stone/stalactite that's reinforced through various methods that's supposed to symbolize their enduring love and solid foundation. The headboard of the berth has stars and constellations carved into it. And when you lay down on the berth, when you look out at the window directly positioned in front of it you can see the stars and skies above. The exact same view/spot from the ledge they used to sit at in their younger years and it’s their own little secret of why their berth is built in that location.

Post-Sentinel betrayal, the High Guard are presumed/declared dead along with the Primes. Now imagine Skyfire lying in their berth alone and looking out at the view from where he lays. He can still see the sky as usual, but he can no longer see the stars that are supposed to be there too. The view is technically the same, but it feels emptier because the star that matters most to him is missing and gone.

Poly Primes in TFONE. Prime Polycule. And Sentinel’s Jealous about it

[saritamanyalu]

I feel like Sentinel 100% has perched on ALL the Primes at least once

Prima: Megatronus, did you saw Solus and Zeta- Uh.. What is Sentinel doing there?

Megatronus glances at Sentinel who was sleeping on his shoulder and looks at Prima.

Megatronus: He was tired, I let him take a nap.

Slides D-16 a pile of Megatronus Prime decals and leaves

stares at the pile of decals for a long moment

Oh my Primus...! Where did you get these?! I-

sees that you're already gone and carefully picks up some of the decals, grinning

Thank you so much...

This is related to your heat/rut au (?) headcanons- Ngl I never thought I would hear/see the words Sentinel and cute in the same sentence but now that I look more at it it does seem like smth he would do. aaand if you don't mind me asking do you have any Sentinel headcanons or maybe some for 13 primes? ;>

Sentinel in heat thinks he is just the cutest, hottest, most irresistible bot on Cybertron, and he WILL get some spike!

I will make a master post of 13 Primes headcanons soon, but I’ll give you some A LOT more Sentinel~

When Sentinel goes into heat around the Primes, his whorishness increases tenfold. His most desired mates are Megatronus, Prima, and Alpha Trion. His frame views Megatronus as the strongest candidate, most capable of producing strong offspring and defending them and Sentinel. It sees Prima as the most desirable for genetic purity, since he’s the first Prime. He’s also big like Megatronus, which he likes. Alpha Trion catches his frame’s attention because of his cat-like beast mode and behavior, which makes him desirable for his agility and unique caretaking instincts. When Sentinel is around any of these three while in heat, he will be found rubbing up on them, touching them anywhere he can, whining and purring at them, and taking every opportunity that presents itself to bare his valve at them. Upon the slightest indication of interest in mating with him, he will immediately bend himself over the nearest surface or get on his servos and knees and spread his legs.

If his three favorites deny him for whatever reason (perhaps they are too busy doing important Prime things) Sentinel will go to the other Primes and loudly complain about it with whines, whimpers, and pitiful cries of despair that might have made them think he was dying if he wasn’t venting out his heat pheromones all over the place. As soon as he knows he has the attention of one of them, he zeroes in on them, flirting via touches and more of his begging whining. If he gets the attention of multiple, his slutty aft will bare his valve to them all and watch any who are interested fight each other for first dibs. Seeing any of the Primes fight over him for mating rights makes him obscenely wet.

And when one of them finally frags him? He’s so fucking loud about it that spit roasting him is common practice, just to make him a little quieter. Except when it’s Prima. Prima, the pinnacle of divinity, adores Sentinel, and the sounds he makes when he’s taking massive Prime spike in that plush, deliciously sensitive valve of his. Especially when he’s in heat. Sentinel is so loud, in fact, that during his first few heat cycles, some of the Primes would - aggravatingly - stop mid-round because they’d think Sentinel had overloaded and was getting overstimulated, when he very much had not. It took a while, but they did figure out the signs of Sentinel’s overloads: his legs squeezing their waist so tight they can’t move, his digits digging into their plating so hard it sometimes actually hurt, his wings arching up and out and shaking with the strain of release, and his cries becoming much longer and cutting off with sobs of pleasure.

Then, when his heat is finally satiated, the Primes gently clean him up (Alpha Trion will lick him clean like a fucking cat) and tend to any minor damage to his plating, including touching up his paint and giving him a nice polish, before all the participants snuggle up around him and let him cuddle them as he recovers from the ordeal. They’ll gently pet Sentinel, kiss him, hold him, and praise him, and he will often be so relaxed by the aftercare that he will slip into recharge right then and there.
