Ultra Kaiju Monster Rancher
Keyword list & Monster Data

North America Art Ultra Kaiju Monster Rancher

North America version (English or Chinese)

Over 2 million Keyword permutations were solved to curate the largest collection in the world of unique Kaiju spawns for every breed in the game. Every Kaiju has their baseline entry + at least one "Guts -2" variant, and thousands of additional variants for stat aptitudes, starting stats, and extra techs. These keywords will work regardless of English or Chinese language being chosen on first launch of the North American version of the game.

For variants, Cells are shaded Green or Red where an attribute is Better or Worse than their pure baseline.
NOTICE: See the Locked Kaiju replacements explanation under NFC

The Digital North American version does not have a "Random" button for Keywords feature like the physical JP and SEA Album versions have, so we've built one for you if you prefer to be completely surprised and use what you randomly get!
