This tier list ranks Brainrots by income efficiency, not raw cash per second. A unit that costs $1M and earns $10K/s is better than one costing $100M for $50K/s. Updated for The Return update (January 2026) with Fuse Machine Secrets.
S-Tier (Must Have)
These units offer the best return on investment at their price points.
| Brainrot | Rarity | Income | Why S-Tier |
|---|---|---|---|
| Strawberry Elephant | OG | Varies | Rarest unit in game, flex piece |
| Los Trios | Secret | $150M+/s | Easiest Fuse Machine Secret |
| Ketupat Bros | Secret | $145M/s | Gingerat + Ketupat Kepat fusion |
| Bacuru and Egguru | Secret | $145M+/s | Bacon and egg duo from Fuse |
| Hydra Dragon Cannelloni | Secret | $100M+/s | High earner from Update 35 |
| Spinny Hammy | Secret | $17M/s | Good for rebirth grinding |
Strawberry Elephant has a 1/100 quadrillion spawn chance. Only about 10 players own one. If you see it, steal it immediately.
A-Tier (Excellent)
Strong units that should fill your base once you can afford them.
| Brainrot | Rarity | Income | Notes |
|---|---|---|---|
| Graipuss Medussi | God | $250K+/s | Required for Rebirth 18 |
| Nuclearo Dinossauro | God | $400K/s | Top God tier |
| Garama and Madundung | God | $300K/s | Solid God tier earner |
| Spongini Quackini | Mythic | $13K/s | New from The Return |
| Diamond/Rainbow Mythics | Mythic | Varies | Mutations multiply value |
Brainrot Gods are your bread and butter before Secrets. They spawn every 30 minutes and generate serious income.
B-Tier (Good)
Useful for progression but replace them when you can.
| Brainrot | Rarity | Income | Notes |
|---|---|---|---|
| Standard Mythics | Mythic | $2K-8K/s | Replace with Gods eventually |
| Mutated Legendaries | Legendary | Varies | Gold/Diamond versions are solid |
| Top Epic units | Epic | $300-500/s | Early game workhorses |
Don't sleep on mutated lower-tier units. A Rainbow Epic can outperform a vanilla Mythic.
C-Tier (Average)
Fill slots with these until you find better options.
| Brainrot | Rarity | Income | Notes |
|---|---|---|---|
| Standard Legendaries | Legendary | $500-800/s | Decent but not exciting |
| Most Epics | Epic | $200-400/s | Replace after Rebirth 3 |
| Mutated Rares | Rare | Varies | Only if heavily mutated |
These units are fine for early game but become slot wasters later.
D-Tier (Below Average)
Only keep these if you have empty slots.
| Brainrot | Rarity | Income | Notes |
|---|---|---|---|
| Standard Rares | Rare | $50-200/s | Sell for better units |
| Bottom Epics | Epic | $200/s | Not worth the slot |
Sell D-tier units before Admin Abuse events to free slots for potential Secrets.
F-Tier (Avoid)
Never waste slots on these.
| Brainrot | Rarity | Income | Notes |
|---|---|---|---|
| Commons | Common | $10-50/s | Only for first rebirth |
| Cursed mutations | Any | Negative | Actually lose money |
Commons are only useful for your very first rebirth. After that, they're a waste of space.
Mutation Impact on Rankings
Mutations can move units up 1-2 tiers:
| Mutation | Effect |
|---|---|
| Rainbow | +2 tiers |
| Bloodrot | +2 tiers |
| Diamond | +1 tier |
| Gold | +1 tier |
| Lava | +1 tier |
A Rainbow Legendary competes with standard Mythics. Always check for mutations before selling.
Building Your Lineup
For optimal progression:
- Early game (Pre-Rebirth 3): Fill with Legendaries and Epics
- Mid game (Rebirth 3-10): Target Mythics and Brainrot Gods
- Late game (Rebirth 11-18): Hunt Secrets, use Fuse Machine
The Fuse Machine returned in The Return update. Submit four Brainrots to get a random unit back. It's the best way to get Secrets like Los Trios, Ketupat Bros, and Bacuru and Egguru.
Don't hoard low-tier units. Sell them or fuse them for better chances.
