For the Royal Prime AU, the only four Primelings are Bee, Elita, Dee, and Pax. The other Primes don't have sparklings cause they're busy doing their own thing. Quintus technically has sparklings in the form of the Quintessons who aren't really vicious in this AU, they're just kinda little Quintesson babies hiding in his lab lmao.

This is cause I do headcanon that the Quintessons are somewhat related to Quintus somehow.

In the Eldritch Prime AU it's a little more complicated because I do want to add more Primelings there for the other Primes but I haven't fully finalized the concepts cause I am... extremely indecisive.

Quintus still has his babies here, the Quintessons. I've said it before in an old ask (in an old account SKSKKS) that Quintus is technically the sky in Cybertron, and the stars are the Quintessons. So yes he is holding his little babies. Eldritch Quintus is actually not a deadbeat compared to how I usually think Quintus would be lmao.

And like the ones that are finalized are obviously the main four.

I was also debating whether on making the Elite Trine related to Onyx, or just the concept of flier mechs being Onyx's descendants, so not specifically his children but rather descended from him but I decided not to go with that eventually since Onyx is not the only flight-alt Prime technically and he's more on beastformers rather than the concept of flight-alts in general.

I also debated on making the High Guard Elite (Soundwave, Shockwave, and Starscream) + Skywarp and TC being related to the Primes. However, I'm still debating that cause while they do have a role in the AU, I don't know if it would genuinely even matter if they were related or not skskks.

However, I did have some concepts for them.

So Soundwave, I was debating making him a Primatronus sparkling too. Mostly cause he fits in line with Eldritch Prima's whole thing being eyes.

Shockwave I was lowkey debating either Onyx or Amalgamous. Onyx because in IDW (sorry, a lot of the things I write have IDW inspirations cause it is my second favorite continuity sksksk) he... well let's just say he has ties to Onyx in IDW and I cannot say how due to it being a massive spoiler. Was also thinking about it for Amalgamous since they have that weird cyclopean eye thing going on (though Amalgamous' is a line) and if we're going with TFA inspiration, TFA Shockwave was capable of changing forms between Longarm and his actual form.

Starscream, I was mostly thinking of Onyx. But in this case I also debated making Starscream much more beastformer-like. Like how his true form is actually a very terrifying birdformer like thing.

Skywarp, I was debating on making Vector's since Skywarp's ability is to warp everywhere and Vector is the Prime of Time and Space. That's the only reasoning I have for this by the way lmao.

TC... was also lowkey debating making him another Primatronus sparkling cause... his sonic booms SKSKSKS can you tell I'm basing this off mostly outlier abilities LMAOOO

I also did debate putting Rodimus here, as like Optimus' younger brother but I'm still on the fence on this one since OP's whole thing is being lonely and like... Roddy kinda gets in the way of that SKSKSK.

The only addition I will have to say, and this is cheating I am aware cause he is not from this continuity, is making Damus (or Tarn) a Primatronus sparkling HAHAHA. The reason I say Damus rather than Tarn is that technically in this AU while he does have the appearance and frame of Tarn, his personality is more Damus than anything. This is because I realized one day that funnily enough, Tarn lowkey kinda fits being a Megatronus child cause... he has the mask and (for this AU specifically), he has the siren voice too lmaoooo. So I decided, yeah sure, let's put Tarn in this AU (can you tell I am biased towards certain characters SKSKSK).
