How to unlock the Mirror... MIRROR! achievement in LEGO Batman 3: Beyond Gotham - Definitive Guide
I used the one in the Batcave... as you enter from the Watchtower, come toward the screen as far as you can, then head to screen right across the black and yellow bridge. Go up the steps and straight ahead into the Character Customizer room.
Once in there, step into either of the two customizing machines at the top of the stairs.
In the machine, select a slot (I just used Custom A), randomize it's appearance and abilities, name it something besides "Custom A" (this may not be necessary, but I did it anyway), and make sure you hit the Y button for "Use Current Character", or the achievement won't pop. I had changed my character a half dozen times without doing this, and wasn't getting the achievement until I did that.
The custom character station is in the Laboratory of the Watchtower or in the Batcave.
Starting from the Watchtower Control Room (where the level selector globe is), head down towards the screen then left through the door. Head down towards the screen again and to the left there should be a green and yellow sign above the door. This is the door to the Laboratory. Once inside, head left then up the stairs and you'll see two creator stations. Press to while standing on the crosshairs activate it and then press to select a character. Press again to choose a category to edit and make your changes. When you’re done, press to exit and then to use that character. This will unlock the achievement.
Note: You must exit the customizer with your custom character for the achievement to unlock.

To create a custom character you must go to the laboratory in the watchtower or in the Batcave. To get to the Watchtower lab: Starting from the level select globe, head down and to the left to get back to the main room. The laboratory is the first room to your left and the Create A Character stations are in the top middle. Simply pick any of the custom characters then randomize the character, then equip it and the trophy will unlock. The Batcave lab is located in the back right corner of the Batcave, the really big door.
