I have been trying to think of a way to implement Zurkhan as a playable race, though mainly for making NPCs for encounters down the line.
As a race that basically are the Viltrumites (from the comic Invincible)/Kryptonians in terms of power level, they will probably have well above average stat bonuses that depend on one of the three "castes" that NPCs fall under in the bestiary. So they'd probably have one stat they all get a bonus to (+4) and then the subtype determines their penalties/other bonuses. I'm thinking that each one grants a +4, and they get a penalty of -2 to two other stats.
I'd like to think of the race as an advanced race from pathfinder with a certain amount of RP like a gargoyle or the like.
These would again mostly be used for making NPC characters to lead the conquering forces of this Zurkhan Empire I have thought of in my own home brewed setting I am using for my campaigns.
