I would also consider a White Lantern ring, 1:1 scale infinity gauntlet, or a force-effect lightsaber.
As for animal figures, maybe a JP dino or a replica of some prehistoric megafauna like the discontinued Chap Mei mammoth. Sell the micro-megafauna for big bucks and live comfortably off interest investing the money.
For humans figures, maybe the Figma Darkness when she hits shops. That or any other canon-masochist character that would have no problem being a mini-girl at the mercy of a giant pervert. Was there ever a non-statue figure of Tenko from the Touhou series?
