What is your personal favorite group of monsters? And what is your least favorite group of monsters? And why?
My own personal favorite groups are mostly: Chimerae, Vermin, Plant, Fae, Demon, Tsukumogami. My ultimate favorite is probably Aberration. I just always liked the freaks of nature, the bizarre, the magical and insane.
My least favorite group is probably the Gods, never cared much for powerhouses! Don’t really care for the Humanoid group that much either.
And while most of these creatures (spare for some fake myths) come from mythology, this is from my own project. So some undead aren’t undead in the myth/folklore/cryptid stories, and many plants aren’t plants in the real myth, same with Oozes. But otherwise most monsters end up in the same groups which is boring.
