LEGO Super Heroes DC 70912 Arkham Asylum

LEGO set 70912, “Arkham Asylum,” depicts the institution associated with Batman’s rogues in the setting of The LEGO Batman Movie. Released in 2017 under Super Heroes DC, it belongs to the Batman branch of the theme and contains 1628 pieces.

Arkham Asylum focuses on a well-known Batman location rather than on a vehicle or a small confrontation scene. Within Super Heroes DC, it sits in the Batman category and is specifically tied to The LEGO Batman Movie, giving the theme a fixed institutional setting for Gotham stories.

Set 70912 contains 1628 pieces and 13 minifigures. The lineup includes Batman, Robin with green eyes, Barbara Gordon, Dr. Harleen Quinzel with red glasses, and female and male GCPD officers. Prison-clothes versions of the Riddler, Two-Face, the Joker with “Arkham” on the back, Poison Ivy, and Catwoman are also listed. An Arkham Asylum statue is part of the inventory.

The set is aimed at builders and collectors who want a recognizable location from The LEGO Batman Movie alongside character-driven play. It can serve as a display model, while the figure selection supports stories involving heroes, police, staff, and inmates in the same Gotham setting.
