During Fox's big San Diego Comic-Con presentation on Saturday, the identities of Apocalypse's Four Horsemen in X-MEN: APOCALYPSE were revealed. They are Angel (who will presumably become Archangel based on previously released concept art), Psylocke, Storm and Magneto.
ScreenRant writes:
In the comics, the Four Horsemen are mutants who have been brainwashed and manipulated by Apocalypse in order to serve as his own personal guard, taking up the titles of Death, War, Pestilence and Famine. We’ve known for some time that Angel/Archangel (Ben Hardy) will be one of the Horsemen – presumably death – and now the other three have been confirmed: Psylocke (Olivia Munn), Storm (Alexandra Shipp) and Magneto (Fassbender).
According to Isaac, Apocalypse’s main ability is the power of persuasion, which he uses to entice these aforementioned mutants into becoming his allies. Hardy also boasted about having “really badass wings,” which we’ve already seen in concept art for X-Men: Apocalypse. During the panel Hardy’s character was referred to as Angel, but it’s possible that he’s transformed into Archangel after being recruited by Apocalypse, based on the mechanical wings that he’s sporting in the concept art.
The how and the why these mutants were chosen is still unknown but at least there is confirmation on who the Four Horsemen are.
