My answer to this question would be improved if I knew of a Humanoid-type creature with a large number of racial hit dice. Such creatures are rather rare—Humanoids usually have just one racial hit die (which is replaced by class levels), and most “humanoid-shaped” creatures with more racial hit dice are Monstrous Humanoids instead.
Still, I’m pretty sure that some Humanoid-type creatures with more than one racial hit die exist. So what are they? Which has the most?
Any Wizards of the Coast-published D&D 3.5e materials, as well as any 3.5e issues of Dragon and Dungeon magazines, are valid. Templates don’t count. The creatures must be playable, i.e. have a listed, numerical level adjustment, rather than LA – or no listed LA at all.
