It's the headquarters of the Legion of Doom, occupied by the evil Lex Luthor! Kids can turn Lex Luthor on the disk at the entrance to raise and lower the elevator. Turning Lex Luthor on the top disk transforms the entire Hall of Doom-the "eyes" open and light up, the hidden cannon is revealed and the cage drops ALL AT ONCE! The adventure continues on the back with all sorts of interesting sculpted details that help kids add to the story about Lex Luthor and the Legion of Doom spying on their foes!
