Homebrew Kaiju Species Details

Utter monstrosities to the world. It is your decision to prove them wrong... or right...

The Folly of Man

The Kaiju are known by many to cause devastation and destruction wherever they go. Most Kaiju are reclusive, retreating from societies for long periods of slumber. It is the arrogance of the races which has brought their slumber to an end. Fully grown Kaiju are titanic beasts, towering hundreds of feet tall. Their immense size and abilities grant them domination over any area which they enter. Unfortunately few societies are able to withstand the presence of a fully grown Kaiju.

As a young kaiju, you have only just begun to grow. Finding help from strangers is extremely difficult for Kaiju, but once a bond is created it will be protected fiercely. A select few Kaiju are seen as protectors of their societies. These Kaiju were typically heavily intertwined with the life cycle of their land dwelling counterparts. These Kaiju fight ferociously against other Kaiju who may threaten their societies. 

Appearance

Work with your DM to design your unique Kaiju appearance. Many will have a bipedal form, but that is typically where the humanoid features end. Kaiju appear to me amalgamations of various animals, or plants, spliced and mutated into a new form. An easy way to create your Kaiju is to look at a beast and decide one of its unique aspects (spines, sharp claws, a long tail). Exaggerate and grow this aspect, or place it in a new location (the claws and spines are massive, the tail connects to the head, etc.). Do this for one or two more beasts and combine a your aspects into your new form.

In a world with other races like dragonborn, tabaxi, or lizardfolk, scaly skin may not automatically make you a Kaiju. However, your appearance will be rather monstrous, so discuss with your DM how as a young Kaiju you might try to hide some of your monstrous features to more easily blend in. Do you wear a mask to cover your fanged maw? Do you wear a cape to cover the spines protruding from your back? Is your four part tail held in such a way to look like one? This race is designed to be fully customizable to the best of your imagination.
