After Batman's drones were destroyed during his fight against Killer Croc, Bruce took a visit to Wayne Tower, where he asked Lucius to build new drones for him. Fox then told Wayne about new apparel he built for him, such as the Line Launcher, which would enable Batman to quickly slide to other locations.
