Dive Deep into Creativity: Discover, Share, Inspire
Bumblebee listens to 100 gecs and uses TikTok. Both of which he does with his speakers turned up. In public.
Prowl has considered buying a fur suit but stops himself every time he's about to go through with it.
Optimus purposefully misuses slang and memes to watch the crew members that know what the terms mean die inside. Even pronounces them wrong for extra flavor.
Ratchet watches soap operas. It started out as simply being curious as to what trash the humans consider good stories but then he got legitimately invested.
Sometimes Bulkhead tries eating human food just because it looks really really good, but it always inevitably tastes kinda gross because he wasn't meant to process that kind of material. He wants to find a way to convert it to energon but until that day comes, he's forced to simply stare and long for it.
The repair crew has movie nights once a week with Sari, both to get a better understanding of human culture, and as an excuse to hang out. Every once in awhile they accidentally pick a movie that they don't realize Sari probably should not be watching until it's too late. They do not speak of the Friday the 13th incident. Or the time Sari picked Coraline and Optimus had to leave halfway through.
In that vein, after realizing how jumpy he was about spiders on Halloween, Optimus actually tried giving himself a degree of exposure therapy so no harmless tiny arachnids needlessly die by his axe. Now he at least TRIES to bring them outside with a cup and a piece of paper, but he's not above just asking Bulkhead to do it instead.
Ratchet has taken to finding old junker cars and trying to fix them up in his spare time. Their makeup is painfully simple compared to Cybertronian anatomy, and it's not like he has to worry about what happens if he can't fix one fast enough. He still thinks just selling spare parts on the open market is barbaric, but it's kind of therapeutic for him to just work on something like that without the stress of having someone's life or even just general well-being in his hands. He lets Bulkhead repaint them when he's finished.
Sari does NOT actually know how sex works. At least, like, not accurately. The version of it she told to Optimus was wildly off-base, but still juuuust close enough to freak him out.
Similarly, Prowl has observed nature long enough to get a sort of incomplete idea of how all that goes down, and has come to the conclusion that organics universally lay eggs.
Bumblebee plays horror games with the lights off just to prove hes not chicken, and then has horrible nightmares for a week straight. He also fully believes in every video game creepypasta/myth you tell him, and swears up and down he's seen Herobrine.
Bulkhead is terrified of mice because he doesn't understand how anything can be that teeny tiny and he heard they can chew through metal like some kind of freaky organic scraplet. He gets nightmares about Ratchet opening him up and finding a whole colony of them chewing on his wires.
Sometimes while Megatron was just a head in Sumdac's lab, he'd be bored enough watch whatever was on TV between schemes and naps. The only thing he would ever admit he liked was wrestling because he felt at least a little vindication watching the pathetic organic wretches beat the slag out of each other. That and it reminded him a bit of his gladiator days.
Shockwave is a pretentious energon tea drinker and has whatever the Cybertron equivalent of a loose leaf tea infuser is. He INSISTS it's objectively better and whatever the more normie type of energon is simply cannot compare.
Lugnut has date nights with Strika but they usually start off as sparring matches that get juuuust a little out of hand. He would not have it any other way and loves when his big scary wife throws him across the room and into a wall, then immediately rushes over to check if he still functions. It may be the concussions, but he swears she looks like a holy being towering above him from where he's slumped over on the floor.
Blitzwing is actually pretty functional from day to day. He's had his multiple faces for long enough that he knows how to cope with them and work with them. Sometimes he has poor impulse control, and sometimes he can't stop himself from feeding his anger, but overall he's actually pretty good about keeping himself in check. He just leans into the whole "crazy" schtick because he knows that's how others see him and no matter what he does, he's not gonna change their perception. It's sort of a spite thing when he annoys people with it, but it's also kind of a self deprecating cry for help that he's REALLY hoping someone will eventually pick up on.
Starscream is only a Decepticon because he wanted to pursue acting but nobody would hire a Warframe. He sought out fame and adoring fans in the gladiator arena, and he got what he was after until Megatron kicked his skid plate and Starscream was suddenly no longer the popular seeker heartthrob bad boy, but a laughing stock who fell when someone bigger and stronger clipped his wings. He originally joined Megatron with the intent to climb the ranks and snatch his following out from under him, but then the war broke out and his whole plan was thrown off track.
No Cybertronian is 100% okay with Earth vehicles looking the way they do and not being alive. It's pretty creepy seeing what they think is just some guy carrying an organic around only to remember right, yeah, the organic's controlling him like cordyceps in an ant and he was never alive to begin with.
Blurr has to intentionally talk much slower than he would at his natural speaking pace just because nobody can understand what in Primus's name he's saying.
Between him, Jazz and the Jet Twins, it's actually kind of a meme on Cybertron that the elite guard badge messes with your speech synthesizer because Sentinel is the only member that speaks even slightly normally.
Jazz once attempted to show Sentinel a nature documentary that Prowl recommended. Sentinel proceeded to purge his fuel tank about five minutes in and forbid jazz from watching that filth outside his own quarters.
Both of the jet twins play fortnite whenever they're on earth and come up with the nastiest incomprehensible insults they can to spam into the microphone because they think that's just part of the game that nobody is taking seriously rather than unbelievably toxic people having mental breakdowns at losing.
And finally,
Cybertron has its own cryptids and urban legends: a long, serpentine beast, as long as 60 Warframes that slinks through the oil of Iacon's aqueducts. A jet black cybercat with three tails that will take your spark if you look it in the optics for too long. A shuttle painted in neons, appearing at the station on its own when there is only one transformer at the station, speaking honeyed words in a voice that sounds too familiar, and promising to bring you home safe, but keeps driving and never stops until you're in stasis or offline. A spectral figure that haunts the underground tunnels that few dare traverse, keeping to the shadows and darting out of sight, but you can always hear their engine revving, and always hear their anguished wails. A frame-bare mechanical avian, practically skeletal, that circles over the sea of rust, massive in size and always waiting to swoop down on unsuspecting mechs. They are spoken of in hushed whispers, none know for certain whether they are real or simply fiction. Most think it's silly to believe in such things, but the superstitions around them persist.
