You do not lose your Brainrots when you rebirth in Plants vs Brainrots. You keep all your Brainrot units, along with some other key stuff that makes progressing after a rebirth much easier.

What you lose on rebirth

When you rebirth, a few progression resources get wiped so you can “start over stronger.”

You lose :

  • Cash / money balance.
  • Boss levels.
  • Spawner upgrades.

This is why it feels like going “broke” after you hit rebirth, even though your account is actually stronger overall.

What you keep on rebirth

The important part: your core collection stays.

You keep :

  • Brainrots (your money‑earning units).
  • Plants.
  • Gear.
  • Previous rebirth bonuses (luck, income boosts, etc.).
  • Island expansion upgrades.

So your best Brainrots are safe, and they’ll help you rebuild cash and levels much faster after each rebirth.

Why rebirthing is still worth it

Rebirth is basically the game’s long‑term progression system.

Each rebirth typically:

  • Increases your Luck (better chances for rare stuff).
  • Increases your income rate (you earn money faster).
  • Unlocks better bats, bigger island, and sometimes card packs or new bosses.

Because your Brainrots and plants stay, those permanent boosts let you hit your previous power level again in way less time after every rebirth.

Bottom line: rebirth will reset your money, boss levels, and spawner upgrades, but your Brainrots are safe, and rebirthing is designed to make your account stronger in the long run.
