The antagonists for every game in the series get increasingly larger in scope for their goals, with the first having a Big Bad Ensemble of Riddler, Penguin, and Joker simply terrorising Gotham, the second having the Big Bad Duumvirate of Joker and Lex Luthor trying to take over America, the third having Brainiac threaten to capture all of Earth for his collection, and DC Supervillains having Darkseid potentially enthrall all life in the universe to his will through the Anti-Life Equation.The spinoff DC Supervillains slightly downscales to between 2 and 3, with various locations around Earth condensed into one map and some travelling to Apokolips. Each of the mainline games increases the scope of the gameworld further, with the first limited to various parts of Gotham, the second extending to all of Gotham and Lexcorp from Metropolis, and the third expanding to all across Earth and to the various Lantern planets.Secondary Adaptation: This is a June 2008 series of video games based on the LEGO toy line inspired by the 1989-99 film and cartoon adaptations of the Batman comic book franchise.Running Gag: Killer Moth's obsession with lightbulbs pops up in all three games.Rummage Fail: Solomon Grundy and Swamp Thing will toss various items like boulders and bicycles out of swamp pits before finding the item needed in the level.Radiation-Immune Mutants: Characters already altered by chemicals, such as Joker or Two-Face, can't be harmed by radioactive waste.While the third was not released around the time of any film, it was released in honor of Batman's 75th anniversary it also had DLC promoting The Dark Knight, Man of Steel, Arrow, and the then-upcoming Suicide Squad. Product Placement: Batman was timed to tie in with The Dark Knight and Batman 2 with The Dark Knight Rises.
Laura Bailey channels both Arleen Sorkin and Tara Strong as Harley Quinn. And, of course, Rob Paulsen as the Riddler is doing his Jim Carrey impression mixed with a bit of Gilbert Gottfried.
