Hello hear me out. Fusing a bunch of good ships.
Dreadwing x Optimus x Ultra Magnus x Predaking
Local married trucks each get a boyfriend after convincing them to switch sides. Soon enough it turns into a full polycule.
Local ex decepticons have no idea how it happened but they are NOT going to complain. They're both very possessive and protective of their big-hearted boyfriends.
Ooooooooooo this is good!!!!!!! Ultra Magnus and Optimus have been together for a long time, but have been separated cause of the war... :( Optimus isn't even sure if his husband is alive :(((
Optimus does manage to convince Dreadwing to join the autobots this time around, well, not 'join' them so much as become a neutral who lives with them. He'll have a greater chance to avenge skyquake with the autobots help after all. It's a mess, it takes forever for everyone to even start to get along but Optimus is just happy it worked. And maybe happy he gets to spend more time with Dreadwing... He didn't expect to like the former decepticon as much as he does. They get close, really really close...
(ironically enough I think Dreadwing and Arcee are chill with each other compared to everyone else just because they both bond over wanting to rip Starscream's face off. It's the little things that bring people together ❤️)
And then Ultra Magnus arrives on earth! Drama! Jealously!! Action- nah I'm kidding I think they get along pretty well. Optimus and dreadwing haven't really figured out their feelings yet, but Optimus and Ultra Magnus have a long talk about Dreadwing and I think they've always had a very loving free relationship ❤️❤️
Also I think Dreadwing and Ultra Magnus would just get along in general. In a non war au they should be friends!
And then, during the fight with Predaking, Ultra Magnus gets taken. Dreadwing's showing up tipped the scales for the autobots but Predaking still wants answers! He needs someone to answer for his kin needlessly dying!!! And that's how he finds out it was the cons who caused it. Drama! Horror!!! Romance!!!!!!! Wait- romance!?!? 😳😳😳😳
Anyways they have a thing™ going on and Ultra Magnus manages to clumsly convince Predaking to return to the autobots with him.
The bed situation in the autobot base is dire 😭 4 of the biggest guys wanna share a bed and that is NOT an option, they don't have enough room, truly tragic.....sometimes of course they want to sleep one on one, including a few memorably times Ultra and Optimus wanted to sleep together and Predaking and Dreadwing had to curl up together ('had to' acting like they didn't willingly curl up together they just didn't want to admit it)
Aughhhh it's all so cute... Good ending for all...
