IMDB lists them as War, Pestilence, Famine and Death.. Death being the one who shields Apocalypse until her end. I much preferred them over the X-Horsemen.
You know the thing with that is, those were seasoned horsemen who were probably with Apocalypse for years. He just threw this new team together and hoped for the best lol.
but i don't think we'll see him in another ensemble XMen film possibly Wolverine solo film. You know when Singer/Kinberh like an actor character then will using them over and over. By next film I'm hoping a lot of these repeat characters drop off and we focus on Jean,Ororo,Scott,Kurt and Jubiliation
