Upon reaching level 86, you'll unlock access to three challenges, which once completed will grant you the exclusive Shapeshifter Emote. For this first challenge, you'll have to change in a phone box while wearing Mystique skin.
Red telephone booths are available at various points on the map. Here's where the one with the easiest access is located.
The cabin chosen here is located to the south of the Doom's Domain, a place that is explicitly shown on your map. All you have to do is enter it dressed as Mystique. You'll then take the appearance of one of Doctor Doom's henchmen.
A challenge of choice for the queen of camouflage!
