<b>"</b>Angels" aren't all as innocent as we think, and angels in X-Men: Apocalypse are an example. In the newly exposed concept art, the metallic wings make the angel look cool and a little more evil. Director Brian Singer revealed to the media that Warren Washington III (the Angel) is certain to be played by Ben Hardy, but he will not be a "good angel".

In the comics, Warren's wings are broken, and the villain Apocalypse (Oscar Isaac) is willing to help him regain his ability to fly, but only if he becomes his own follower. Then, the angel regained the organometal wings and was transformed into a "archangel" and became a member of the "Four Horsemen of the Apocalypse", all four knights were genetically modified mutants who obeyed the Apocalypse, and changed many generations, Wolverine, Pokémon, Spider-Man, Scarlet Witch, Iron Man, etc. have all been Apocalypse Knights. In the end credits of the movie X-Men: Reverse Future, the original "Four Horsemen of the Apocalypse" made their debut, but only in the shadows of the dunes.
The big boss in the film always has to have a few powerful helpers, just like the previous "X-Men" in Magneto has a magic woman, red devils and other people, this time the "Apocalypse Knight" will cause a devastating blow to the X-Men.
