At the beginning of the game, Professor Honda will give you the Kaijudex and explain how it works. One of the features is the Danger level of each Kaiju. A level 0 Kaiju is often used for techonologically created beasts that aren't really a threat, a level 1 Kaiju is used for small beasts that represents a small threat, a level 2 Kaiju is used for most of the beats and represents a big threat, a level 3 Kaiju represents an above-high threat and a level 4 Kaiju is a "beast to be slayed within minutes because it represents a gigantic threat and it cannot be tamed".
In gameplay, those levels represents the chances of capturing a beast, a level 0 Kaiju has a 75% Catch Chance, a level 1 Kaiju has 60% Catch Chance, a level 2 Kaiju has a 45% Catch Chance, a level 3 Kaiju has 15% Catch Chance and a Level 4 Kaiju has a 0.1% catch chance.
Players will also meet with Level Unknown Kaiju, those Kaiju has a randomized catch chance, each turn they change, example when fighting a Level Unknown Kaiju at the first turn, there are five possibilites of a catch chance: 15%, 25%, 32%, 68% or even 99%, at the second turn the numbers will change, increasing more five possibilites at each turn. If it reaches at turn 20, then the chances immediatly decreases to 0%.
This also has an effect in battles, a Kaiju with a higher threat level has a bigger chance of winning the battle (but that doesn't means they will always win the battles). This also has effects on abilities, depending of the ability.
