Mighty Omega is Kengun Omega’s hardcore anime fighting game — a paid-access experience where you train a martial artist from nothing, pick up fighting styles from boxing to Muay Thai, clan-hop your way through a city full of other players doing the same, and settle arguments in some of the most demanding combat on Roblox. Progress is slow, stats matter enormously, and rerolls are precious.
That is what makes its codes valuable: they drop currencies, rerolls and seasonal items like Halloween Candy Jars that would otherwise take serious grinding. The catch is that Mighty Omega burns through codes faster than almost any game we cover — well over a hundred have expired — so the working list is usually short and worth claiming the day you see it.
All New Mighty Omega Codes
- halloweenstarts25v2: 25 Halloween Candy Jars (==NEW==)
Yes, the working list really is one code long right now — and note the “v2” at the end. The original halloweenstarts25 is already dead, so do not waste your time on it; the version-two code below is the one that still pays out.
Expired Mighty Omega Codes
Mighty Omega retires codes at a rate few games match, and the graveyard below is every code that two independent trackers agree is finished:

How to Redeem Mighty Omega Codes
- Launch Mighty Omega on Roblox.
- Train first: your Total Power needs to reach at least 30 before the game lets you claim codes at all.
- Head to the Bookstore near the Police Station and talk to the NPC Allen Merkz inside.
- Choose “I want to claim a code”, type the code into the box, and press Redeem.
How to Get More Mighty Omega Codes
Kengun Omega releases codes around events, updates and shutdown apologies, often several at a time and rarely with much warning. The game’s community channels and the developer’s announcements are where they surface first, and they can expire within weeks. Given how fast this game’s codes die, your best strategy is simply to check this page whenever an event is running — we re-verify the list against multiple trackers and prune the dead ones as they drop.
Why Are My Mighty Omega Codes Not Working?
Double-Check for Typos: Mighty Omega codes are long, lowercase and unforgiving — some are practically sentences. Never type them by hand; copy and paste, and check that nothing was trimmed off either end.
The Code Has Expired: With 100+ retired codes, expiry is the default explanation in this game. If a code came from an old video or a months-old post, assume it is in the graveyard above until proven otherwise.
Your Total Power Is Too Low: Code claiming is locked until your Total Power reaches 30. New characters cannot redeem anything, no matter how fresh the code is — train up first, then visit Allen Merkz.

Conclusion
One live code, twenty-five Candy Jars, and a mountain of expired ones — that is Mighty Omega in a nutshell. Claim halloweenstarts25v2 while the Halloween stock lasts, keep training toward your next style, and check back after the next event for the inevitable fresh batch.
