Kaiju are destructive by nature, dismantling things regardless of reason or purpose. Because of this, many kaiju are chaotic neutral.

Kaiju reach adulthood in their early teens and live no longer than 50 years. They cease aging physically after adulthood.

In their normal form, kaiju mostly resemble humans, with minor differences being in their glistening red eyes and protruding hair-colored horns

Your creature type is humanoid. You can speak, read, and write Common and one other language of your choice.

As an action, you can temporarily transform into a monstrous reptilian for 1 minute. While transformed, you gain the following benefits:

• Your size is increased by 1 category.
• Scales begin to grow and harden from your skin. Whenever you take damage, gain 1 AC (max of +3 AC).
• Your Strength-based attacks deal double damage to objects and structures.
• You gain a pair of sharp claws, pointed teeth, and a massive tail, which you can use to attack as a bonus action on your turns. Successfully hitting a target deals 1d8 piercing, slashing, or bludgeoning damage. They count as simple melee weapons for you, and you add your Strength modifier to the attack and damage rolls when you attack with them, as normal.
• Whenever you take damage, you must make a DC 10 Wisdom saving throw or temporarily fall into a fit of blind rage. During your turns, you must try to attack the nearest creature you can see. If no creature is near enough to move to and attack, you must instead attack an object, with a preference for an object smaller than yourself. This rage continues until you receive magical healing, are unable to attack during your turn, or your transformation ends.

Once you use this trait, you can't use it again until you finish a long rest.
