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.
The four ways a kaiju gets locked
- Straight purchase. Most of the roster. You farm cells, you buy it, it is yours. Everything from 1,000 up to 125,000 works this way with no other condition.
- Purchase plus a level chain. The endgame pattern. Space Godzilla wants 500,000 cells and Heisei Godzilla at level 100, Biollante at 75 and Godzilla Junior at 25 — so the real cost includes buying and levelling three other kaiju first.
- Purchase plus a level-and-kill chain. Destoroyah Final Form is the deep end: 1,500,000 cells, plus both Destoroyah Aggregate and Destoroyah Flying Form at level 100 with 100 kills each. Kills, not damage — building-farming does not advance it.
- Neither. Showa Ghidorah is free if you join the developers' Roblox group. Monster Zero is not bought at all — it is ten skulls, one per server, and the only currency it costs is your evening.

A sane unlock order
Buy Biollante at 50,000 before anything else in that bracket. It is not the strongest thing you can afford, but wide area damage and 4,900 HP is what turns a crowded Tokyo server into income rather than a death — and every later unlock on this page is paid for out of that income. The cell farming page covers the routes.
Then decide whether you are chasing Space Godzilla or Destoroyah Final Form, and commit. Both chains want a different set of kaiju levelled to 100, and splitting your play between the two means arriving at neither. Space Godzilla's chain is the shorter one — three kaiju, no kill requirement.
Do not spend on a second cheap kaiju while your main is still under its level cap. Limit Break raises that cap to 200, and the power you buy there is almost always larger than the power you buy from another 6,000-cell body.
Costs we could not find
Kaiju added in the last few months — Shimo, Monster X, Orga's second form, Striker Eureka, MUTO Prime, Titan X — have no published price anywhere we could check. They exist, they are on the kaiju list, and their unlock numbers are simply not written down yet. Guides that quote you an exact figure for these are quoting themselves. When a source appears, the number appears here with the source next to it.
