Every Brainrot in Escape Tsunami for Brainrots, Ranked by Rarity and Income

Escape Tsunami for Brainrots wraps an endless-wave runner around an idle tycoon. Your brainrots aren’t just memes on pedestals; they are the backbone of your income. Each one has a set rarity and a fixed cash-per-second rate at base level, and the farther down the runway you run between tsunamis, the rarer and more lucrative they get.

The game currently organizes brainrots into nine rarities: Common, Uncommon, Rare, Epic, Legendary, Mythical, Cosmic, Secret, and Celestial. On top of that, mutations like Gold, Blood, Diamond, or Emerald can further boost individual units, but the base values below are what everything is built on.

Brainrot rarities and how income scales

Each rarity band has its own income range:

• Common brainrots start at just a few dollars per second and cap in the low teens.
• Uncommon units jump into double and low triple digits per second.
• Rare and Epic brainrots reach hundreds to a little over one thousand per second and define the early game.
• Legendary and Mythical pieces push into thousands and tens of thousands per second.
• Cosmic and Secret brainrots deliver tens of thousands up to a million dollars per second.
• Celestial brainrots sit at the very top, in the 1.5M–1.9M per second range at base.

Rebirths then multiply that income, but they don’t change these base values. Your money snowballs fastest when you combine high-rarity brainrots with a strong rebirth multiplier and upgraded individual levels.

Celestial brainrots (highest rarity)

Celestial is the current top tier. These units spawn only in the Celestial section beyond the Secret area, and they appear on a timer rather than existing permanently on the runway. You need high speed just to reach them before the wave hits, and you’re often racing other players at the same time.

Celestial brainrots and their base income:

Celestial spawns are periodic rather than constant, and their positions along the runway change. Expect to camp the Celestial section and repeatedly ride out waves while waiting for the next spawn window. In practice, players often build late-game bases almost entirely out of Celestial units and their mutated variants.

Secret brainrots (late-game chase units)

Secret brainrots live just in front of the Celestial area and are the first tier that can surpass some Cosmics by a wide margin. They are still static pedestals rather than timed spawns, but they sit far down the runway where waves come in faster and closer together.

Secret brainrots are usually a realistic target once you have several rebirths under your belt and your speed upgrades make the earlier sections trivial. Filling an entire floor of your base with Secrets dramatically increases your passive income, even before touching Celestials.

Cosmic brainrots (transition to high income)

Cosmic brainrots form the bridge between mid-game Mythicals and the high-end Secret tier. They are spread across the latter part of the main runway, before the Secret gate.

Once you can reliably reach this section, it is usually worth replacing almost every earlier unit in your base with Cosmics, then selectively swapping them out for Secrets and Celestials as your runs improve.

Mythical brainrots (strong mid-game picks)

Mythicals live just ahead of the Legendary section and can be your main earners while you’re still building up rebirths and speed.

Fully upgrading a handful of Mythicals can carry your rebirth progression and make it much easier to bankroll future speed levels.

Legendary brainrots (early to mid-game backbone)

Legendary brainrots fill in the space between Epic and Mythical. They are not as explosive as the high tiers, but they are inexpensive enough to upgrade and replace frequently.

In practice, once you can comfortably reach this section, it makes sense to phase out most Epics and below, keeping only particularly strong Epics until you can replace them with Mythicals and Cosmics.

Epic brainrots (strong early picks)

Epic brainrots are accessible relatively early and deliver income high enough to meaningfully accelerate your speed upgrades.

If you are in your first few rebirths, it is usually more efficient to focus upgrades on a small set of your best Epics and Legendaries instead of spreading money thinly across many lower-rarity units.

Rare brainrots (early progression workhorses)

Rare brainrots are likely to be your first big upgrade from Uncommon units. Their incomes are high enough to matter but low enough that you can afford many upgrades without massive rebirth multipliers.

Once your base is mostly Rare and Epic, you can start thinking about rebirthing more often, since your unit income will help you rebuild speed levels much faster after each reset.

Uncommon brainrots (first meaningful upgrades)

Uncommons appear very close to spawn and are the first noticeable step up from the weakest Common units. They are the easiest way to get your early base out of the single-digit-per-second range.

Because Uncommons are so close to spawn, early waves are the perfect time to fill your base quickly with them before you can reliably handle deeper runs for Rares and above.

Common brainrots (starter units)

Common brainrots are the starter tier. You will grab them in your first few runs while you are still learning wave timings and scraping together enough money for speed and carry upgrades.

Common units fall off very quickly in usefulness. As soon as you can reliably reach Uncommons and Rares, it is worth replacing most Commons to avoid wasting pedestal slots on low earners.

How brainrots, speed, and rebirths fit together

Speed is the main stat that decides how far down the runway you can get between waves and therefore which rarities are realistically in reach. Rebirths convert speed progression into a permanent cash multiplier, and brainrots are the passive generators that fund both.

Rebirths in Escape Tsunami for Brainrots are tied to speed levels rather than a raw money threshold. Tapping the Rebirth button on the left side of the screen brings up a panel that shows the required speed level and the money multiplier unlocked at the next rebirth. Confirming only wipes your speed upgrades; you keep your carry level and every brainrot in your base, which is unusually generous for this kind of system.

The early rebirth requirements and multipliers look like this:

With this structure, each rebirth slightly raises the bar by another 10 speed levels while also raising your cash-per-second multiplier by 0.5×. Over time, those bonuses stack into huge numbers, especially when combined with high-rarity and mutated brainrots.

Practical strategy: which brainrots to prioritize

Early on, the most efficient path is straightforward: use Rare, Epic, and Legendary brainrots as your core earners while you push your first few rebirths. Grab any strong Uncommons you can reach in the first seconds of a run, then quickly replace them with Rares once you can consistently survive a few wave cycles.

As your speed climbs, aim to rebuild your base around Mythical and then Cosmic brainrots, focusing your upgrades on a few of the top earners in each tier rather than leveling everything evenly. Once you unlock Secret and eventually Celestial sections, those single units will often outperform entire earlier floors of your base, even before mutations and high levels.

The game is tuned so that Celestial units deliver the highest base income per second, with Secret and Cosmic right behind. Reaching them reliably is a separate challenge from owning them, though, and that is where rebirth planning and careful wave timing matter as much as raw speed.
