LexCorp was originally organized as an aerospace engineering firm started in the top floor offices of The Daily Planet building in Metropolis and has since become one of the world's largest, most diversified multinational conglomerates.
On Metropolis the Locate Keystone appeared outside the building and was stolen by Sauron, who used it to summon the Barad-Dur that lands over Lexcorp. Later Sauron used the Lexcorp's technology including force fields and LexBots to take over the Metropolis.
|To get this Gold brick you first need to climb the building using a character with the Acrobatic Ability (or you can just use a flying character or vehicle). There you will find a terminal cover with silver LEGO bricks, use a character with Silver LEGO Blow Up Ability to destroy the bricks, and finally a character with Hacking Abillity to hack the computer. That will raise a platform in where the Brick is.|
