Odym
Gold Brick #1
Talk to the Green Loontern by the teleporter to get a tour of the planet. Follow him around, taking out the beetles that attack. When the tour ends, you'll receive a brick.
Gold Brick #2
You can also find Aquaman on this planet; he needs help returning a crocodile to a safer place. Follow him and the croc, and punch the green guy in the head any time he stops to snap at civilians. When the croc returns home, you'll get a brick.
Gold Brick #3
You'll find Gorilla Grodd on Odym too. He needs help finding a banana for his ultimate weapon. It's a little tough to find, but you'll have to scour the area to find this tree and sensor spot. Use a sensory character to reveal a dirt patch, use a digging character to pull up a handle, build it onto the tree, and finally grapple it off the tree to shake a banana loose. Return this to Grodd to complete the quest.
Gold Brick #4
Grodd has another quest for you: dealing with his ex, Giganta. To defeat her, simply hop into the banana cannon and shoot her until she's defeated. You'll earn a brick for it.
Gold Brick #5
For the final quest, you'll have to make amends with Giganta. To do this, follow her and take out 30 bugs as they appear. Once they're all defeated, you'll receive a Gold Brick.
Gold Brick #6
The rest of the Gold Bricks can be found underneath the beacons in the sky, one of which points to a flying challenge. To win, simply fly through all the rings before time runs out.
Gold Brick #7
There's another flying challenge above a rock arch. Zip through the rings just like the first time to win another brick.
Gold Brick #8
There's a footrace to complete here too. Dash through all the gates before time expires for a Gold Brick.
Gold Brick #9
One beacon points to the crashed Brainiac ship. Inside and around it are six of these blue engines; destroy them all to kill the lasers surrounding the Gold Brick inside the ship.
Gold Brick #10
The village area (also marked by a beacon) holds 14 - yes, 14 - flags. Bust one up, then scan the rooftops to find the others and bust them before time runs out. You'll win a Gold Brick if you're successful.
Gold Brick #11
One beacon points to this flower, which you can bust up to reveal dirt patch. Use a digging character to pull out another brick.
Gold Brick #12
Finally, a beacon will point you toward this group of silver rocks. Use a demolition character to blow away the top one, revealing a switch. Step on it to open the chest below, which holds a tinier silver box. Blow this up too to find a Gold Brick inside.
