First, that Meraginasu looked to have a bunch of moves that I'm unfamiliar with. Going to guess that it's an announcement for the HC version. (If so, looks like my guess was right)

Second, the Yama looks so overdesigned that I couldn't see it as an HC version. It most likely is a G Conquest War monster.
