Very incredibly curious about your plural!Jetfire/Skyfire ideas
Ok so, the plural Skyfire/Jetfire came to me for SEVERAL different reasons
1. Everytime I see a character that canonically has more than one name I either hit them with the trans beam or the plural beam, sometimes both like here
2. The various continuities ways of characterizing him is REALLY interesting. Im fond of the scenes Ive seen of him in WFC especially (both the netflix triology and the games), because it feels so subtly unique compared to other interpretations Ive seen more often that it's just stuck in my head. WFC Jetfire also remind me a lot of Agent Ukulele (scp character, primarily the one in our own system) so Ive just been kinda rotating them in my head for a hot minute now
3. The ice. I get that Skyfire is a shuttle and thus built to withstand colder temperatures, but being stuck in ice for *several million years?* That can fuck with anyone. Get silly with it, get angsty with it, do *more* than just have him stuck in a coma for 4 million years, its bound to affect him
The last reason is a big one Ive been playing around with recently with @sarcosticsarcomere while planning stguff for our roleplay server because you can go several different routes with it. The easy one is give him PTSD and all that fun stuff, the real angsty one is have his spark go out and have Starscream try to ""reignite"" it in a fit of hysteria. The latter option is fun because I can incorporate the idea of cold-constructed frames and the real life phenomenon of organ transplant receivers often gaining memories, urges, or even muscle memory from their donor that they didnt have previously. So taking all of that into account, what you have is a really cool base idea that you can branch out from.
I personally think that Skyfire was a median plural even before the ice, due to Reasons, but being stuck in the ice definitely had a big effect on their plurality. I have ideas for different headmates beyond just the two have the Skyfire and Jetfire names, but those two are absolutely the hosts that you see most often. Alongside that, a lot of people don't really talk about introjects a whole lot in relation to characters in their sources, but theres definitely a few in the Skyjet system, the most prominent likely being a factive of *Starscream* that acts a lot closer to how she did pre-war when they were both at the academy than how she does as the Decepticon Air Commander
