Kaiju Codex

I’m very happy to announce that the Kaiju Codex is now available from Rite Publishing on DriveThruRPG. I have converted this product to the fifth edition of the world’s most popular roleplaying game, from Pathfinder rules. In this PDF, you’ll find stats, stories, and roleplaying notes for 20 different kaiju, as well as a mech to fight them in called the Iron Knight. I hope you’ll pick up a copy!

Here’s the official marketing copy:

It’s Going to be Colossal! 

Kaiju Codex brings you 20 new massive monsters for Game Masters to use in their 5th Edition roleplaying game ranging from the natural disaster style Worldshaker to the lesser Kaiju like the Hubrun, or The Big Goblin, so you can find a challenge to fit your game! This product adds some new twists so you can make the existing Kaiju even more dangerous!

We also include The Iron Knight for Player Characters to crew, so you can have Kaiju vs Mech-like combat. There is an artifact for PCs to control a Kaiju for a short period of time, so you can Let Them Fight!

Plus advice on GMing Kaiju so your game can play like a Japanese Monster Movie or focus on something more classical like Jörmungandr, The World Serpent.

Check out the full-sized preview and get your copy today!


I want to give my deepest thanks to the late Steve Russell, who first offered me this project. I never met him in person, but he touched the lives of a huge number of gamers, and I’m proud to be a new member of the Rite Publishing team. They are wonderful, clever, and dedicated people.
