giant Joker-esque robot piloted by Luthor and the Joker. The villains use the robot's kryptonite weapon to subdue Superman and crush Batman with a large crate, unaware that the heroes had swapped costumes prior. Having survived, Batman and Superman pursue the robot and destroy its flying gear before Superman is exposed to its kryptonite power source, causing him and Batman to crash-land in Gotham. The pair make their way to the city hall, where Luthor discovers that the Joker's gas' affectionate properties were only effective on the Joker, not Luthor. Following another fight with the robot, Superman damages its power source, causing it to leak liquid kryptonite, but is left completely weakened. Robin arrives in a multi-colored Batmobile, which counters the Deconstructor's effects, and he and Batman trick Luthor and the Joker into chasing them around Gotham. The kryptonite creates a giant Joker face, which is seen from the Watchtower by Martian Manhunter, who contacts the rest of the Justice League: Wonder Woman, Cyborg, Green Lantern and the Flash. Once they arrive to help, Luthor concedes defeat but attempts to destroy Wayne Tower in an act of retaliation against Bruce Wayne. Superman recovers his strength and he and Wonder Woman try to save Wayne Tower, while the others battle the Joker robot on top, sending it plummeting onto the street below. With the robot destroyed, the Joker and Luthor (now wearing power armor) come out to fight the heroes, but are ultimately defeated, while Green Lantern rebuilds Wayne Tower's supports, stabilizing it. As the two villains are arrested, Gordon thanks Batman for saving the day, to which he admits he could not have done it without his friends' help, and that he is glad to have friends that he can always count on. As the League prepare to rebuild the Batcave, Green Lantern shoots a beacon from his power ring into space in victory. The beacon is seen by Brainiac, who utters "I have located it"; hinting at its appearance in LEGO Batman 3 Beyond Gotham Development Concept The idea of a sequel to Lego Batman: The Videogame began shortly after its release. The success of the first game led TT Games to begin development of a sequel. Early in the development process, a open-world design system was considered and later built upon.
