I love them so much, there should be more Rid 2015 Drachet fanart!

All Transformers have a scent that's uniquely theirs. You can smell it off them from birth and then it sorta dulls a bit as they age, but you can still smell it off them here and there, usually in their vehicle modes.

Here's some I've listed.

Bumblebee: Warm honey.

Strongarm: Patchouli.

Sideswipe: Birchwood campfire.

Grimlock: Freshly cut grass.

Drift: Musky jasmine.

Slipstream: Honeysuckle and lime.

Jetstorm: Lilies of the valley and lime.

Steeljaw: Baked bread.

Thunderhoof: Maple syrup.

Fracture: Lavender.

Airazor: Petrichor and neroli.

Divebomb: Petrichor and oranges.

Underbite: Iron, mostly.

Clampdown: Seawater.

Fixit: Burnt sage.

Optimus Prime: Laundry detergent (Tide brand).

Windblade: Elderberries.

Glowstrike: Bubblegum.

Saberhorn: Bee balm.

Scorponok: Damp wood.

Quillfire: Pine.

Scatterspike: Lemon balm.

More about Bee's team on your au because there's not much about them (not that I know at least) pleaseeeee🫶

I'm going to assume you mean GOTP since I haven't really covered them much for that one, but if not then that can be a separate post XD

Strap in, we've got a ways to go—

Bumblebee

He is promoted to lieutenant on Cybertron, but— much like many other autobots of the War-Era— he finds an oddly widespread dislike of him, even from his fellow Autobots. He finds an overeager fan in Strongarm, but even that isn't enough to fully pull him out of the slump he's felt since the war ended, especially after losing Optimus, his mentor, on top of everything else.

Suddenly, he's been summoned back to Earth by the ghost of Optimus Prime, to protect it from an unknown threat. He hijacks a spacebridge against High Council regulations, and finds Strongarm and Sideswipe dragged with him. While he's happy to return to Earth, there's a sadness and anxiety that comes with it, as it was the last place he saw Blades before laying him to rest.

Even after Sigma Seventeen is found to be revived, Bumblebee remains overprotective of his team, not wanting to lose them to an accident like he did the others...

Sideswipe

Sideswipe is labelled by some as a troublemaker and snoop, but really, he's a young bot on a mission. One afternoon, without warning, his twin brother Sunstreaker was arrested on unknown charges right in front of him and then disappeared, even from Sideswipe's twin-bond that normally would lead him right to his other half. Sideswipe is determined to find his brother, even get arrested himself so he can hack federal logs from his cell.

Being handcuffed to a young cop wannabe and dragged through an illegal spacebridge portal to some Primus-forsaken planet was not on his To-Do list, and he holds a grudge against Strongarm for delaying his efforts.

Sometimes, when Sideswipe gets particularly heated, some have mentioned seeing a strand of light from him that reaches into the heavens. What it is or where it's tied to, nobody knows... yet.

Grimlock

The Dinobots— and non-vehicle-moders really— aren't seen as being the brightest bulbs in the street sign, and Grimlock knows it. Formerly a popular player on the Cube scene, Grimlock and his fellow dinobot friends named themselves in commemoration of their ancestors' sacrifice back in the day, and fight to prove they deserve equal treatment amongst the masses despite their kind's reputation.
