Deviljho is new and thrilling (and IIRC available to hunt at the start of High Rank when he turns up randomly, so he's hardly last monster unlocked). Alatreon is the last monster, I believe.

And really I'm just kinda bothered the last monster in the game is a Subspecies. A good Subspecies I guess, but a sub nonetheless.
