Kaiju Alpha Codes — Roblox (Checked October 22, 2026)
The working Kaiju Alpha code on October 22, 2026 is NOLIMITTOTHELARVA, which gives 20 levels once you've played for 30 minutes. The older 1MILLIONMEMBERS code (50 levels, 500,000 Cells and 5-hour EXP and Cell boosts) was set to expire on October 16, so it may no longer work. Redeem codes from the main menu of the Roblox game Kaiju Alpha by the verified group SULU OPPA: press Options, paste the code into the Enter here box and press Enter.

1MILLIONMEMBERS |
50 levels, 500,000 Cells, 5-hour EXP boost, 5-hour Cell boost | Needed a SULU OPPA group join and 1 hour of play. It was set to expire on October 16, 2026, so it probably won't work now. It's worth one try: some trackers still list it |
NOLIMITTOTHELARVA first showed up on code trackers in mid-October, as the game's Heisei Mothra content was being added. We list a code only when at least two independent code trackers show it as working.
How to redeem Kaiju Alpha codes
- Open Kaiju Alpha on Roblox. Check that the creator is SULU OPPA (verified badge).
- Codes only work from the main menu, not during a fight. If you're in a match, press the Menu button above your skills while out of combat and wait 10 seconds.
- Press Options on the main menu.
- Paste the code into the Enter here box at the bottom and press Enter.
Codes aren't case-sensitive, but copying them avoids typos. If a code says it can't be redeemed yet, the usual reason is the playtime requirement: keep playing and try again.
Expired Kaiju Alpha codes
These no longer work: XECRETISREAL, KAONTOP, BADSONGLEE, SINGULARITY, DEAWYGIGACHAD, SRRYFORBUGS, SRRYFORBUG, SRRYFORBUGGUYS, SRRYFORREVERTLEVEL, ROSE, REWARD.
The "Srry" codes were apology codes after bug fixes, so a new one often follows a big patch.
What's new: Update 54 (Heisei Mothra)
The current update, according to the game's Roblox description on October 22, 2026, added:
- Heisei Mothra Larva and Heisei Mothra. The developer notes that the Mothra removed earlier was the Showa version, not Heisei.
- Balance changes for Godzilla in Hell: A1 max damage 690 → 640, A2 980 → 900, A5 400 → 385, A3 Special 300 → 200, A5 Special (Devil Bat Power) 350 → 450, and Immortal Apocalypse charges 2 → 1.
Controls: keys 1–5 use your five skills, R and T are your two roars.

Where new codes come from
New codes come with updates and member milestones. They're posted first in the developer's official community channels, and the SULU OPPA Roblox group is required for some rewards (1MILLIONMEMBERS needed a group join). We check this page every day.
What we won't cover
- Scripts, auto-farm or "infinite Cells" tools. They break Roblox's rules and can get your account banned.
- Buying or selling Kaiju Alpha accounts. That's against Roblox's terms, and account sales are a common scam.
