Ok, I saw these yesterday too. Is the Dark Elf the same as Kurse? Or are these 2 different figures? Pardon my ignorance but I only know the classic Thor characters from the comics.
I didn't notice what the articulation looked like, sorry.
Kurse and the Dark Elf are two separate figures/villain characters. I managed to find a Dark Elf for myself the other day. Kind of bummed that this figure is only one per case, because it's pretty cool, and sure enough an army builder.
Kurse is an individual villain who IIRC is a fairly major villain in the Thor storylines. Although I'm surprised that the other main villain from the movie, Malekith, hasn't been represented yet in the figure line. Although I do hold out some hope that he might come in a later wave if the figure line goes beyond this first wave.
