About this converter
Pacific Rim ranks kaiju on a fixed one to five category scale. Onibaba opens at II, Knifehead and Trespasser tied at III, Mutavore, Leatherback, Otachi, Raiju and Scunner tied at IV and Slattern at V. That makes Slattern two and a half Onibabas of category. Every value here is the canon class with Jaeger matchups noted where they help. Nine named kaiju fill this ladder with no filler, since the films only classify this many.
How to use it
Pick two kaiju and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. One box holds a count of the first, one holds the matching count of the second, one holds the total in categories. Try 1 Slattern against Onibabas.
Jaeger heights for the same film run on the companion Jaeger page, since pilots and monsters measure on different ladders. The Anteverse keeps sending stronger classes, which is why the finale stacks four Category IVs plus a V. Category I kaiju stay unnamed on screen and stay out rather than ever guessed at.
