LEGO Batman 2 DC Super Heroes - Unlocking All Villain Characters in Gotham City Central

This shows how to unlock all of the villain characters in the Central Gotham City area of LEGO Batman 2 DC Super Heroes. In order to do this, you must first locate and activate each Batcomputer remote terminal. The location is shown as a red beam of light. The characters that I unlocked in this video are The Joker, Bane, Brainiac, The Penguin, Sinestro, Killer Croc, Killer Moth. The Joker and the Penguin are the two most important characters to unlock from this area because they have special abilities that are needed to collect several minikits in free play mode. The Joker is also needed to get several red bricks in the overworld.
Below are the times in the video when I unlock each character and how much it costs to unlock them.
