Basically, you select them like you’d select an alternate costume. Instead, you have to select the character, then find the appropriate skin in the outfit color selection screen and equip it in your loadout (Reverse Flash for the Flash, John Stewart for Green Lantern, and Power girl for Supergirl).
The skins aren’t in the character selection screen, because they’re not characters, they’re costumes. Players might have confused the premier skins with actual fighters. For some, the problem might stem from a simple mix-up.
