In Steal a Brainrot, most Brainrots appear regularly and can be collected with enough cash and patience. Secret Brainrots, however, exist on an entirely different level. These ultra-rare characters are the most difficult to encounter, but they also generate some of the highest income in the game. Unlocking even one Secret Brainrot can dramatically accelerate your tycoon progress and give you a long-term advantage.
At present, Steal a Brainrot features 143 Secret Brainrots, making them the largest and most exclusive category of characters. Below, you’ll find a full list of every Secret Brainrot currently available, including their income output and required cost — essential information for players who want to optimize earnings and build the strongest possible setup.

Buying from the Conveyor Belt is the most luck-dependent method, as Secret Brainrots appear extremely rarely. To improve your chances, many players choose to enter a private server to avoid competition, activate a Luck Boost for a short increase in drop rates, and save a huge amount of in-game currency in advance so they can buy the unit immediately when it finally appears.
Stealing from Other Players happens in public servers and can be risky but rewarding. If another player owns a Secret Brainrot, you can break into their base when it’s unguarded, use tools like traps or spring coils to stop them from reacting in time, and escape quickly before securing the unit in your own base.
Crafting via the Machine is a more reliable option for advanced players. The Crafting Machine in the lobby allows you to trade several Brainrot God units for a Secret Brainrot. Crafting options refresh every 30 minutes, and the process takes about 1.5 hours, making this a consistent method if you already have high-value units.
Trying Your Luck with Lucky Blocks is the fastest but most expensive approach. By purchasing a Secret Lucky Block from the Robux shop, you open a loot-box-style reward with a chance to receive a Secret Brainrot, though the outcome is never guaranteed.
