If you've spent any time in the trenches of the Japanese mobile sensation Uma Musume Pretty Derby, you know the sound of a bubbling test tube is usually followed by a massive headache. Or a speed boost. It honestly depends on how Agnes Tachyon is feeling that day. Among a roster filled with high-energy idols and stoic long-distance runners, Tachyon stands out. She’s messy. She’s caffeine-addicted. She treats the Trainer like a lab rat. But more importantly, the Agnes Tachyon Uma Musume game presence has fundamentally shifted how people approach mid-distance racing and training efficiency since the game launched in 2021.
She isn't just another character you pull from a banner. She is a mechanical anomaly.
The Madness Behind the Lab Coat
Tachyon is a "Srank" (Speed) focused character, which sounds standard until you look at her internal kit. In the actual horse racing world, the real Agnes Tachyon was a literal comet. He ran four races, won them all, and then vanished into retirement due to injury. Cygames took that "brilliant but fleeting" legacy and turned it into a girl who wants to transcend the physical limits of horse girls through questionable chemistry.
In-game, her stats lean heavily into the Speed and Intelligence growth rates. Specifically, she gets a 20% bonus to Speed and a 10% bonus to Intelligence. This makes her incredibly easy to build for beginners but deceptively complex for high-level Champions Meeting (PvP) play. Most players start out thinking they can just stack speed and call it a day. That’s a trap. Tachyon’s true power lies in her unique skill, U7611, which focuses on stamina recovery.
It’s weird, right? A speedster who heals.
But that recovery is exactly why she dominates the mid-distance tracks. She allows you to skimp on the Stamina stat—which is notoriously hard to train without sacrificing raw power—because her "experimental" medicine keeps her lungs from bursting in the final stretch. You basically trade a bit of reliability for an optimized stat spread that other girls can't touch without burning through precious support card triggers.
Why the Science Works
Let’s talk about the 2000m tracks. This is Tachyon’s backyard. In the Satsuki Sho or the Hopeful Stakes, the stamina requirement is just high enough to be annoying. Most trainers have to waste turns in the "Stamina" training camp. Tachyon? She’s in the lab. By focusing on her Speed/Int growth, you’re hitting the 1200 cap (or higher in newer scenarios like Project L'Arc or U.A.F.) much faster than her rivals.
She’s a glass cannon that fixes herself mid-race.
The Support Card Revolution
You can't talk about the Agnes Tachyon Uma Musume game meta without mentioning her Intelligence SSR support card. When "The Speed of Light" card dropped, it didn't just power up Tachyon; it broke the game's ceiling for everyone else.
Here is the thing: Intelligence cards are the most valuable in the game because they don’t consume energy (Vitality). They actually restore it. Tachyon’s SSR card provided a massive "Hint Level" bonus and one of the best gold skills for leaders: Agility. This turned her from a niche character into a mandatory teammate for anyone trying to win the Libra Cup or any mid-distance event.
Honestly, it’s a bit ironic. The character who hates exertive effort is the one who provides the most efficient way to train without getting tired.
Breaking Down the "Tachyon Meta"
If you're looking to actually win with her, stop focusing on her as a Runner. I see people do this all the time because they think her speed warrants it. No. Tachyon is a "Leader" (Preceding) type. Her logic is simple: stay right behind the pack, let the Runners waste their stamina fighting for the lead, and then use her recovery skill to slingshot past everyone when their legs start to give out.
Specifics matter here. If you're running the U.A.F. Ready GO! scenario, you want to prioritize her "Blue" training links. Why? Because Tachyon thrives when her skill activation rate is high. Intelligence isn't just for recovering energy; it’s the stat that determines if she actually remembers to use her healing potion or if she just fumbles it and loses the race.
- Target Speed: 1400+ (in modern scenarios)
- Target Intelligence: 1100
- Stamina: 600 (Lower than you think, because of her unique skill)
- Power: 1000+ to ensure she can push through the crowd
The "New Track" and Evolving Scenarios
The game has changed a lot since the early days of the URA Finals. We've gone through the MNT (Make a New Track) era, the Grand Live, and now into the hyper-specialized modern scenarios. In every single one, Tachyon has remained relevant.
In the Grand Live scenario, which was all about "Lessons" and "Songs," Tachyon’s high Intelligence growth allowed players to farm "Performance Points" more consistently than almost any other character. You could basically chain-train her without ever hitting the "Rest" button. It felt like cheating.
But there’s a downside. Tachyon is incredibly sensitive to the "Insonmia" or "Night Owl" status effects. It’s a flavor-text win but a gameplay nightmare. If she gets a bad status, her training efficiency craters. You have to be prepared to burn a Tazuna or Hayakawa visit just to get her head back in the game. It’s the "Mad Scientist Tax."

The Aesthetics of Winning
People love Tachyon because she’s a disaster. Her lab coat is stained, she’s perpetually tired, and she talks to herself. In a game full of "Perfect Girls," she’s a relatable mess. But when that gate opens, her animation is one of the coolest in the game—digital grids, glowing chemicals, and a look of pure, calculated mania.
It’s that contrast that keeps her at the top of the popularity polls. You’re not just training a horse; you’re managing a genius who might accidentally blow up the training center.
Essential Insights for Competitive Play
If you’re serious about the Agnes Tachyon Uma Musume game experience, you need to look at her "Inheritance" potential. Even if you aren't racing as Tachyon, her "Unique Skill" is one of the best to pass down to other girls.
Characters like Oguri Cap or Mejiro McQueen benefit immensely from Tachyon’s stamina recovery. By using Tachyon as a parent (Factor), you can give your long-distance runners a "safety net" recovery skill that triggers exactly when they need it most.
- Look for "Power" and "Stamina" factors: Since Tachyon already gets speed bonuses, her parents should provide the stats she struggles to gain.
- Inherit "Non-Stop Girl": This is the best acceleration skill for her position. If you can get it through a support card or inheritance, she becomes nearly unstoppable in the final corner.
- Don't ignore the "Aura": When she triggers her skill, it has a specific visual cue. If it triggers too early, you haven't given her enough Intelligence. If it triggers too late, her Stamina was actually too high. There is a "Goldilocks Zone" for Tachyon that takes practice to find.
What Most People Get Wrong
The biggest misconception? "Tachyon is only for mid-distance."
While her kit is designed for 2000m-2400m, with the right factors (10+ stars in Long Distance inheritance), she can be a monster in 3000m+ races like the Arima Kinen. Most players don't try this because they’re afraid of the stamina drain. But remember: Tachyon is the stamina drain’s worst enemy.
Also, stop using her basic 1-star or 2-star variants if you have the 3-star "Agnes Tachyon" base or her seasonal alts. The stat weights are significantly better on the upgraded versions. If you're a F2P (Free to Play) player, Tachyon is your best friend because she’s one of the few low-rarity characters who can consistently beat 3-star gacha-exclusive girls.
Actionable Steps for Your Next Training Run
To maximize your Agnes Tachyon runs, start by auditing your support deck. You need at least two high-level Intelligence cards—ideally her own SSR or the Fine Motion SSR.
First, focus purely on building her "Bond" levels in the first year (Junior Season). You want those "Rainbow" training sessions to appear as early as possible in the second year. Second, don't be afraid to take the "risky" options in her random events. Unlike other characters where a "Failure" just means a stat loss, Tachyon’s events often give unique buffs that can’t be found anywhere else.
Finally, keep an eye on the race schedule. Tachyon needs those G1 wins to build her "Fan Base," which in turn unlocks her skill levels. If you miss the Satsuki Sho or the Japan Cup, you’re leaving her potential on the table. Hit the 1200 Speed mark, keep her Intelligence above 1000, and let the science do the rest.
