Kaiju
Every Kaiju Alpha kaiju in one roster reference, covering unlock methods, game pass and shop sources, hidden requirements and the role each monster fills.
Introduction
The Kaiju Alpha roster is the reason most players install the game. It leans heavily on the Godzilla universe, spanning the original Gojira 1954 and Gojira 1955 starters, the modern Godzilla 2014, 2019 and 2021 chain, alternate forms such as Burning and Thermonuclear, and endgame monsters like Evolved Godzilla and Destoroyah Final Form. Around that spine sit Toho classics including Mechagodzilla 2021, King Ghidorah, Biollante and Gorosaurus, plus modern titans such as Kong, Skar King and Shimo. This category is a roster reference: how each kaiju is unlocked, whether it comes from the shop, a game pass, an event or a hidden requirement chain, and what role it fills in arena fights, farming runs and boss modes once you actually own it.
Roster Roles and Unlock Paths

Godzilla Unlock Chain
Godzilla 2014 leads to Godzilla 2019 and then Godzilla 2021, the spine of the shop progression.
Hidden Unlock Kaiju
Monster Zero and several advanced forms hide behind collection tasks rather than a simple shop price.
Modern Titans and Crossovers
The roster reaches beyond the Godzilla line into Kong, Skar King, Shimo and other famous movie monsters.
Core Mechanics
Roster progression in Kaiju Alpha runs on two currencies and one gate. Cells are earned from player kills and building destruction and buy shop kaiju, while XP levels a single monster toward the level 200 cap. Limit Break then opens the tier above that ceiling, which is where endgame forms reach their real strength. Not every kaiju follows the shop path: some are game pass purchases, some arrive through limited events, and others hide behind collection requirements such as the ten skulls the community ties to Monster Zero. New monsters also arrive constantly, with Update 48 adding Rose Biollante and Update 49 adding Zilla 2004 alongside an inventory system, so any roster reference is always a snapshot of the current build.
Advantages
A roster reference prevents expensive mistakes. Because each kaiju has a unique five-skill kit and its own stat curve, two monsters at the same price can perform very differently, and understanding a kaiju's intended role before buying it is worth more than any single match. Knowing the unlock method matters just as much: a player who realizes Monster Zero reportedly needs collected skulls can gather them during ordinary farming instead of saving Cells for a shop purchase that does not exist. Finally, tracking additions and remodels helps veterans revisit monsters they dismissed, since a remodel can change animations, stats and tier placement within a single patch. That foresight keeps a Cell balance pointed at a monster your account will actually keep using long term.
Challenges
The biggest limitation is confirmation. The full roster and its unlock requirements are drawn from community sources, and the complete in-game list has not been officially published, so some entries and costs carry only medium confidence. Names such as Hakaishin Godzilla, Titan X and Striker Eureka appear in community material without official confirmation, and hidden requirements like the ten skulls for Monster Zero are consensus rather than documentation. New kaiju also arrive so quickly that any reference ages within weeks, and remodels can quietly change a kit you thought you knew. Treat every unlock cost and hidden requirement here as a starting point to verify in game. If an official source later contradicts a community claim, trust the game itself.

Quick Tips
Check the unlock method before you save. Some kaiju cost Cells in the shop, some are game pass purchases, and others hide behind collection tasks such as the ten skulls reported for Monster Zero. Knowing the requirement early stops you from banking Cells for a monster that never appears on the shop list, and it lets you gather hidden items during normal farming runs instead of wasting extra sessions.
Do not judge a kaiju by its movie fame. A famous monster can have an awkward kit with slow skills and poor mobility, while a lesser-known pick fits the arena better. Read how its five skills and two roars actually work, consider its movement and range, and pick for the role you need. Roster reputation and in-game strength are not the same thing in Kaiju Alpha.
Watch for remodels and new additions. Kaiju Alpha adds and reworks monsters at a rapid pace, with Update 48 bringing Rose Biollante and Update 49 adding Zilla 2004 alongside an inventory system. A remodel can change a kaiju's animations, stats and place in the meta, so recheck any monster you dismissed months ago, since older advice may describe a kit that no longer exists.
Budget your Cells for one endgame project. The roster looks enormous, but funding several unlocks halfway leaves every one of them weak. Pick a target chain, such as Godzilla 2014 into 2019 and 2021, finish it, then level that main toward the cap. Scattered spending is the fastest way to stay stuck fighting starter kaiju with an inventory full of unfinished monsters.
