Arkham Asylum

The LEGO® Arkham Asylum (set 76300) is a 2953-piece LEGO Batman set released in 2025, a detailed recreation of Gotham's notorious institution housing its most dangerous inmates. The modular building splits into three segments — ground floor, first floor, and roof — with removable elements granting access to opening prison cells, an inmate delivery van, and 65 stickers referencing decades of Batman lore. The set includes 16 minifigures: Batman, Batwoman, Batwing, Robin, Mr. Freeze, The Riddler, Poison Ivy, Catwoman, Scarecrow, Harley Quinn, Bane, The Joker, The Penguin, Killer Croc, and two security guards. Pieces arrive in 24 numbered bags, doubling the build as a Batman-themed advent calendar.
