Kaiju Alpha Kaiju List
Roster checked:
Prices are in Cells. The community wiki writes some of them as "U-cells" — its own U-cells page is a redirect to Cells, so the two names refer to the same currency.
Showa
The starter block. Everything here is either free or cheap enough to buy in a first session, and the whole tab is filled in on the community wiki.

Heisei
Where the price curve breaks. Two of the four are gated behind levelling other kaiju first, which is the real cost.
| Kaiju | Cost | Flies | Requirement | HP |
|---|---|---|---|---|
| Biollante | 50,000 | No | None | 4,900 |
| Heisei Godzilla | 125,000 | No | None | not published |

| Destoroyah Final Form | 1,500,000 | Yes | Level 100 Destoroyah Aggregate with 100 kills + Level 100 Destoroyah Flying Form with 100 kills | 6,800 base / 8,600 max |
| Destoroyah Aggregate | not published | No | Step on the Destoroyah chain | not published |
| Destoroyah Flying Form | not published | Yes | Step on the Destoroyah chain | not published |
Millennium, Reiwa & Monsterverse
These are the tabs the community wiki still has as "Placeholder", so almost nothing here has a published stat line. Everything listed is a kaiju we can show exists from the official description or dated creator footage — the numbers are what is missing, not the kaiju.
| Kaiju | Cost | Flies | Requirement | HP |
|---|---|---|---|---|
| Kiryu (Type 3) | not published | No | not published | 3,850 base / 5,350 max after Update 45 |
| Godzilla 2000 | not published | No | not published | 3,850 base / 5,450 max after Update 45 |

Teased, not yet confirmed live
Announced or shown in teasers. We list them separately because "it was in a teaser" and "you can pick it right now" are different claims.
| Kaiju | Cost | Flies | Requirement | HP |
|---|---|---|---|---|
| Keizer Ghidorah | not published | not published | not published — the popular "requirements" videos are explicitly predictions, not published numbers | not published |
| Godzilla 2014 remodel | not published | No | not published | not published |
Pulled from the game
Hakaishin Godzilla
Added and then pulled. "Why was Hakaishin Godzilla removed from Kaiju Alpha" is one of the most-searched Kaiju Alpha phrases of the last month, and creator coverage of the "Hakaishin update aftermath" ran to ~30,000 views three weeks ago.
Status: No longer selectable. We have not found a first-party statement giving the reason, so we do not print one.
Where the sources disagree
Two conflicts are worth knowing about before you act on any Kaiju Alpha roster, ours included. We print both sides rather than picking one:
How many game passes are there?
The community wiki contradicts itself. Its Game Pass page says there is currently only one — Tank, at 50 Robux. Its Kaiju page says Frostbite Godzilla, Thermo Godzilla and Burning Godzilla each require a purchased game pass, which would make at least four. A rival guide site independently claims the game has exactly one game pass and that it is not on sale. We have no way to read the live game-pass list from outside Roblox, so all three accounts are printed here rather than one being picked. Treat any specific game-pass count you read anywhere — including ours — as unconfirmed.
Godzilla 1954's HP
The main community wiki's page gives 2,400. A second, near-empty Kaiju Alpha wiki gives 3,700 for the same kaiju. We use 2,400 because that wiki is the one with an actual maintained roster, but the two disagree and neither is first-party.
Why some names are missing
Names that show up constantly in search but that we could not tie to the official description, the community wiki or dated in-game footage are deliberately left off this table — among them Zilla, Kamata-kun, Godzilla Earth, Cherno Alpha and Romeo Blue. Several of them are probably in the game. Until we can point at a source you can open yourself, they stay off the roster rather than padding it.
How to read the Source column of any Kaiju Alpha roster
Every entry above rests on one of four things, and it is worth knowing which, because they are not equally reliable:
- The official experience description. The Roblox experience description, which the developers overwrite with each update's patch notes. This is the only first-party source, and it is also the most perishable — it holds one update at a time.
- The community wiki roster tables. Roster tables on the community wiki's Kaiju page (Showa and Heisei tabs; the Millennium, Reiwa, Pacific Rim, Monsterverse, Gamepass and DevOnly tabs are still literally marked "Placeholder").
- Individual wiki pages. That kaiju's own page on the community wiki, where the infobox carries HP, speed and price. Some carry 2026 screenshots; others still show 2022 ones. Age varies page by page, not site-wide.
- Dated creator footage. A dated, high-view creator video that shows the kaiju in game. Good for proving a kaiju exists and roughly when it arrived; useless for exact stats.
That last distinction is the reason this list has gaps rather than a full grid. Proving Shimo is in the game takes one video. Proving Shimo has 6,400 HP takes a source nobody has published yet. Work out which kaiju you want from the tier list, then check what it will actually cost you on the unlock requirements page.
