Killer Moth is a villain who appears in LEGO Batman: The Videogame. Killer Moth is a millionaire who serves as a villain-helper. He wears a garish costume and develops his own line of gadgets such as "the Mothmobile" and "the Moth-Signal" to help criminals get away with their activities.
Killer Moth is one of the many villains who escape Arkham Asylum, and upon his release he joins The Joker's band of villains. Killer Moth, alongside Harley Quinn, Scarecrow, Mad Hatter, and The Joker, plans to bomb Gotham Cathederal and release Joker Gas across Gotham. Killer Moth does not have a major impact on the plan, and his only part was to escort The Joker through the backstreets of Gotham as they move towards the Cathederal to finish the plan. Near to the Cathederal, Killer Moth is ensnared by the spotlight of the Batwing, causing him to stop and stare at it. This pause allows Batman and Robin to catch up to Killer Moth, and he is captured by them. He is last seen in his cell at Arkham, flitting around the lightbulb in his cell.
While he doesn't appear in the main story, Killer Moth can be found in Open-World Gotham at the Gotham Power Station. Here he can be fought as a boss, and unlocked as a playable character.
- Killer Moth is capable of flapping his "wings" allowing him to glide across large distances.
