You hit the nail on the head here, Oceania is not weak, it's dull. I like the directions this thread is taking and definitely think that some sort of summable commander(s) is the way to go. I have some vague memory of Polynesian vampire myths, but can't call up the name. The headhunter/cannibal angle sounds fun to me as well, and i also have a vague recollection of reading folklore from the island of Yap in college that involved invisible sorcerers. Perhaps you could do something with that. And of course there's always Land Sharks!

Looking forward to see what you come up with here.
