Kind of a continuation of "Who will be the villain in Moana?", but that one's getting kinda long (especially during one point where it went off-topic in a discussion about whether a Sonic villain was lame or not), plus now we have a better idea on who or what it might be.
So, based on trailers and info that have been released, it seems there are two candidates for Moana villain, and hopefully not another surprise villain.
The lava witch shown in trailers. Maui asks Moana if she ever fought a lava monster. She seems more menacing than Tamatoa, as it's implied Tamatoa is a comical villain.
Then there's Tamatoa. He is certainly in the right position to be main villain, having stolen Maui's magical fish hook which would give him lots of power, and Maui's mission is to get it back.
So, which of them will be the villain? If so, what role will the other one play? The secondary antagonist (such as the Carnotaur to Kron)? A servant of the other? (no, not The Other, you know what I mean) Or a more minor villain only encountered once?
And while we're at it... will Disney continue their new villain tradition (besides the surprise villain bit), or revive the old one not seen in an animated Disney movie since King Candy's demise?
