Prime Earth (New 52 and Rebirth)
In this continuity, the gun was sold to Joe Chill by Mallory Madison, father of Bruce's future love-interest Julie Madison. Twenty years after the murder of Thomas and Martha, Bruce Wayne purchased the gun on the black-market for fifteen hundred thousand dollars.
Bruce would go on to melt down the gun and use the metal to forge a protective plate beneath the yellow emblem on his batsuit.
In this continuity, Joe Chill murdered Bruce Wayne rather than Thomas and Martha. As a result, Thomas Wayne became Batman and murdered Joe Chill while his wife became the Joker. Thomas not only used to gun as a trophy in the Batcave but would also use the gun himself as his weapon of choice.
Appearances in Other Media
- Batman Begins - Chill's gun is a revolver, used for a mugging outside an opera house
- Super Friends was the first time the gun was shown outside comics, a vision induced by Scarecrow
- Justice League: The Flashpoint Paradox: The gun appears in this film, on display in Thomas Wayne's bat-cave.
- In a planned episode for Batman: The Animated Series, we would have had an entire story dedicated to the gun. In it we'd see the metal for the gun was amorally mined from Native American sacred grounds and was later purchased by mobster Jack Napier before murdering the gun-store clerk. Napier would use the gun to murder the Waynes and we'd later follow the gun through several different episodes until it winds up being melted down.
