Common questions about playable characters in LEGO Batman: Legacy of the Dark Knight — answered using multi-source community data, with conflicting source claims flagged inline rather than guessed.
QHow many playable characters are in LEGO Batman: Legacy of the Dark Knight?▾
Seven base heroes — Batman, Jim Gordon, Catwoman, Robin, Batgirl, Nightwing, and Talia al Ghul — plus two more (Joker and Harley Quinn) arriving with the Mayhem Collection DLC in September 2026.
QHow do you unlock all characters?▾
All seven base heroes unlock automatically through the main story between the Prologue and Chapter 5. There are no cheat codes, no purchases, and nothing is missable.
QWhen do you unlock Catwoman?▾
Catwoman becomes playable during the second chapter, after a mission that introduces her in Gotham. Sources disagree on the exact mission name; the chapter is consistent.
QWhen do you unlock Robin, Nightwing, and Batgirl?▾
Robin joins in Chapter 3 around the Haly's Circus arc. Both Batgirl and Nightwing unlock in Chapter 4 — Batgirl earlier in the chapter, Nightwing in its final mission.
QWhen do you unlock Talia al Ghul?▾
Talia al Ghul becomes permanently playable in Chapter 5, around the Tumbler Chase mission.
QAre there cheat codes to unlock characters?▾
No. TT Games dropped the classic LEGO cheat-code entry system; every character is earned through story progression.
QCan you play as the Joker and Harley Quinn?▾
Yes — they're added in the Mayhem Collection DLC in September 2026 and are fully playable in the open world. They aren't part of the base 7-character roster at launch.
QWhich character do I need for a particular puzzle?▾
Use the Ability Decision Matrix above to map puzzle types (vents, hack panels, foam pipes, etc.) to the hero who solves them. Most puzzles are gated to one or two characters' gadgets.
