About Kaiju Alpha Wiki

This is an unofficial, fan-made wiki for Kaiju Alpha, the giant-monster battleground on Roblox by SULU OPPA (launched August 17, 2026). It is not affiliated with Roblox Corporation, SULU OPPA, or any film rights holder — all kaiju names belong to their respective owners, including Toho Co., Ltd.

Why this wiki exists

Kaiju Alpha updates roughly four times a month and overwrites its Roblox description each time, which destroys the previous patch text. Most guide sites copy from each other and from a same-named 2025/2026 game by a different studio — which is why their prices don't match the live game. This wiki was built to fix exactly that: every value here is checked against the live game's place ID (127403135954624), dated, and graded by source.

Our verification standard

• Three trust tiers. Official text (from the Roblox API), official words preserved in community archives, and community snapshots — every page tells you which tier a claim comes from.
• Codes are cross-checked daily against four tracked outlets. Single-outlet codes are labelled; conflicts are shown as conflicts, not resolved by coin flip.
• Unknowns say unknown. If the developer never published a price, our pages say "not published" and show you how to verify on your own game card — they don't invent a number.
• Known fake codes are named so players stop losing time on fabricated lists.
