LEGO Batman 3: Beyond Gotham/Extras

Extras can be considered as "cheats" in that they grant you special abilities that range from silly cosmetic changes to helpful guides to gamebreaking stud multipliers. There are four Extras available from the start of the game, while the others must be found from each of the main levels. Plastic Man alone is required to get all of the Extras in the game. Even after finding Extras, you must also have enough studs to buy them before you can use them from the pause menu.
