After activating the Remote Terminal, go to the left of the Gotham Bank and then head into the alley on the right. You will arrive at a parking lot. Turn the camera to the right and you will find this character behind the Gotham Bank. Walk towards him to face him. In his boss fight, he will jump towards you and use a stomp attack to attack you. It can be very difficult to dodge the attack because he moves so fast. If you dodge it successfully, quickly hit him to remove a heart. Repeat this three times to defeat Clayface. When you remove his three hearts, you can buy him for 100,000 studs.
To the left of the first metal wall of the third Gold Brick, you will find a broken Gold Door. 20 Gold Bricks are needed to build it. When you have 20 Gold Bricks, build the Gold Door to reveal Vicki Vale. She costs 125,000 studs.
On the edge of the island southeast of Gotham Bank, you will find a black box. Use Lex Luthor's Deconstructor to deconstruct it and reveal this Red Brick, which costs 500,000 studs.
To the left of the left bridge that takes you to the Central Island, you will find a panel with Robin's Acrobat Suit. Put it on as Robin, climb a blue and white pole, do pole stunts, climb a wall to reach a platform, and use a grappling hook to reach the roof of the building. Transform into a trackball, move to a platform and run up to the left to open the fences in front. Go down a slide while still in trackball and follow the path of studs until you see two blue and white walls. Return to your normal form, climb between them, climb a blue and white pole, grab a handhold, and climb another pole of the same color. Grab another handhold and scale a wall to reach the highest roof of the building with this Gold Brick locked in a container. Return to your trackball form, move to a platform and run up to the left to open the container with this Gold Brick. Climb one more blue and white pole and jump towards the container with this Gold Brick.
A little east of Gotham Cathedral, you'll find a panel with Batman's Bat Suit. Put it on as Batman, follow the path of studs and use the wave gun to destroy a glass container and reveal a bat symbol. Then use a grappling hook on it to climb to the roof above, and scale a wall on the left. Walk along some planks, destroy a glass container to put on the Electricity Suit, and climb an electric wall. Absorb electricity from an electrical outlet, walk across the electric floor on the left, and transfer the electricity to an uncharged electrical outlet to open the container with a button. Then, step on the button to turn on a panel with the Power Suit on the right. Launch an explosive rocket at a silver lid to destroy it, and scale a wall. Follow the path of studs by climbing two more walls and use a zip line to reach the roof of another building. Destroy a silver lid to put the Bat Suit back on and destroy the glass walls on the left. Follow the path of studs gliding to the roof of another building and use the wave gun to destroy a glass container and obtain this Gold Brick.
In the upper right corner of the Gotham Bank parking lot, you'll find a panel with Robin's Hazard Suit. Put it on as Robin, clear the purple chemicals next to it to reveal a bat symbol, and use a grappling hook to climb to the roof above. (If your water meter runs out, you can jump to the pond on the right to refill it.) Clean the green chemicals from the front and put on the Magnet Suit. Climb a metal wall on the right and climb another metal wall to find a blue box on the left. Use a magnet to open it and reveal this Gold Brick.
Heading to the street in front of the previous Gold Brick Hazard Suit and then heading left of the road, you will find a panel with Robin's Magnet Suit. Put it on as Robin and climb the metal wall next to it. Use a magnet to remove the silver lid from a panel and put on the Acrobat Suit. Climb a blue and white pole to the right, throw your pole into a hole, and perform stunts on your pole and another pole to reach a platform. Then use a grappling hook to reach a higher platform, climb between two blue and white walls, and use a zip line to reach a pole. Perform stunts on two more poles and use a grappling hook to reach the highest roof of a tall building. Transform into a trackball, move to a platform and run up to the right to open a container with a panel with the Hazard Suit. Put it on and since you are immune to toxins in this suit, you don't need to clean up the green chemicals to climb a wall. Jump into the purple pond on the right to fill your purple chemical meter and throw purple chemicals into the hole of a purple tank to get this Gold Brick.
In the lower left corner of the Gotham Bank parking lot, you'll find this Civilian in Peril being harassed by a Penguin Goon. Destroy the Penguin Goon to save this Civilian.
There is a bug that causes the moving walls of the bank to move Clayface to the right, causing him to speak off-screen in his introduction to his boss fight.
