May 2nd, 2026 is the racing event we’ve all been waiting for: the Kentucky Derby Iacon Derby 2026!! We’re celebrating any and all Cybertronian racers - whether they’re a Velocitron native or tearing up the racetracks on Earth, it’s their time to shine!
Event details:
This is a one day, casual event to celebrate the poorest, most maligned members of Cybertron’s population: famous racers. They need your support!
Five prompts are available to you as part of this challenge - pick the one that speaks to you the most, combine at will, or just stick to your own whims; the prompts are here to inspire, not confine!
Post a drabble, draw a doodle, or just write up some meta about who you think really deserves to win this race! Every little bit counts, and no participation is too small.
You can find the prompts and more details (and some bonus rules that might just win you a fabulous prize!) below the cut.
Time to rev up and roll out!
Praise for Iacon Derby 2026:
“A Cybertronian is like a horse… if you think about it.” - Mod Rumble
“Well, they do run on horsepower.” - Mod Saberhorn
Event guidelines:
🚗 There is an AO3 Collection for this event. You can find out more about adding your work to a collection here.
🏇 If you want us to reblog your contribution to this event on Tumblr, please ping us @mtmtevents and tag your work with #mtmtevents and #iaconderby2026 - this gives us the best chance to celebrate your work!
We will continue to reblog and check the tags for a week after the event, and the AO3 Collection will remain open for the rest of the month of May. Don’t worry about getting everything done exactly on time - just have fun!
🚗 This event focuses on Racers in Transformers. OCs are acceptable, and characters that are not ‘canonically’ Racers would also be acceptable, as long as your contribution still centers around the idea/concept of “being a Racer”. They need to live and breathe (vent?) for the racetrack! This is their career, and they’re not planning on retiring tonight!
🏇 There is no word limit for this event; feel free to post a 100 word drabble, or a 10k fic. Give us your doodles, your long-winded ramblings, your fanvids. Whatever this event inspires you to create, we want to see it!
🚗 NSFW is allowed, and all that entails! Please tag your work, and please be sure to read the tags on AO3 before engaging with someone else’s work.
🏇 AI-generated content (including images, text, ‘reference’ posted in the work, etc.) is not permitted. This event is for fun! The AI can’t have fun for you.
🚗 Have a question that’s not answered here? Feel free to reach out to us by Askbox. There are two mods on this blog who both work fulltime, so we will do our best to answer any questions in a timely fashion, but please be patient! If you would like a question to be answered privately, please say so at the beginning of your message. All other asks will be answered publicly. (PSA: If the vibes are off, Teletraan-1’s automatic defense system will activate and delete your message.)

An Archive of Our Own, a project of the Organization for Transformative Works
Fandom: Transformers - All Media Types, Transformers: Earthspark (Cartoon)
Warnings: No Archive Warnings Apply
Relationships: Bumblebee/Hot Rod (Transformers)
Characters: Bumblebee (Transformers), Hot Rod (Transformers)
Additional Tags: Angst, Hurt/Comfort, Bumblebee Needs A Hug (Transformers), Bumblebee-centric (Transformers), Character Study, Post-Canon, Post-Season/Series 04, Self-Worth Issues, Unreliable Narrator, Post-Traumatic Stress Disorder - PTSD, Depression, Age Regression/De-Aging, Memory Loss, Canon Compliant, mostly. except for the stuff i forgor, also i put some of the whimsy back in hot rod. sorry.
Summary:
“So. This is Earth, huh?”
Hot Rod sounded as tired as Bumblebee felt. He looked around the barn as if there was anything there to see other than Bumblebee’s sorry-looking frame lying listlessly in the middle of the floor and a single horse dozing in the stall next to him.
“What’s that?” Hot Rod said, pointing at the horse.
“His name’s Mystik Dan,” Bumblebee mumbled. “He’s a horse.”
He’d been a racehorse once, Mo had told him proudly. One of the best. And now he was here, living the easy life in his retirement. Bumblebee wondered sometimes if he understood why they’d taken him away from the racetrack, or if he ever missed it. Maybe it made no difference. He’d go wherever they sent him, after all.
iacon derby fic 2: electric boogaloo B) truly cannot believe the silly fic i wrote for the mystik dan bonus prompt ended up being both longer and angstier than my breakbee oneshot LOL but that’s just how it goes sometimes <3

Additional Tags: Bumblebee-centric (Transformers), Hurt/Comfort, Pre-Canon, Post-Cybertronian Civil War, Canon Compliant, that period of time where bee was on his own hiding from ghost for years, Racing, Street Racing
Summary:
The thing was, Bumblebee knew it was a terrible idea.
He was on the run, but it wasn’t enough. There was an itch, deep in his struts, that the prey animal routine just wasn’t scratching. Despite the shadow of G.H.O.S.T. hounding his heels, his engine ached for a race, a real one. This phantom chase just wasn’t the same.
So, yeah, he knew it was a bad idea. But if he didn’t get to burn some rubber on a racetrack soon, he was going to explode, and he was pretty sure that Optimus would rather he was online and taking dumb risks than offlined from boredom and spark burnout. Probably.
happy iacon derby!!! here’s the first of my 2 earthspark bee oneshots i wrote for the event >:)
