#tf one megatronus prime

[sentinel-prime-after-dark]

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.

I image that Sentinel would be perched on Megatronus's(Prion one of the other Primes) shoulder during battle, and then Sentinel full on launches himself on anyone, that tries to surprise attack Megatronus(or one of the other Primes).

Megatronus distracted fighting

Enemy: Your time has come, Megatronus.. About to attack the prime, until the Sentinel appears from behind and bites his leg

Enemy: AAAAAAAAAAAAAAH! Sentinel: GRRRRRRRR!!!

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.

Do you hoard things?

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!

In TFOne setting the 'fallen' in noblefallenforge stands for falling in love! The only falling Megatronus is doing in this continuity is falling head over heels for two very cool and pretty bots UwU

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.

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..?

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...

We all know you get Megatronus merch for dee with your spare credits, but how about yourself? Do you get yourself nice things too?

Who said I always pay for them?

Hah! Just kidding! Mostly.

I’ve gotten myself a few things, but I’m not really much of a collector or anything.
