I ran across a rather interesting HeroQuest Bestiary that was based on Mortimer’s HeroQuest Bestiary (Internet Archive Link)
It’s a 149 page doc with a “create your own monster” section with a unified build cost for statistics. (Apparently based on old Heroscape.)
It appears to have a bit of everything, including some Dragons. (Which are surprisingly low HP, comparatively.)
