Whatever it is, it looks like it will be slow and useless. I'll be saving up for that skeleton god-like figure though.
It's definitely not the Minotaur lulz.
It looks like a merman with an Anglerfish head (deep sea fish with light bulb). I think it will be an elite hero since the Pirate Captain, Minotaur, Necromancer are probably going to be legendaries.
