I never created DC canon.
Gentleman Ghost materialized near a handful of people as they waited for one Metropolis store to open. His top hat was removed before he gave a slight bow. Their wide eyes never bothered Gentleman Ghost. Two flintlock pistols materialized and were aimed at everyone.
''Please drop every bit of cash and jewelry,'' Gentleman Ghost said. It was for a split second when he wondered if Supergirl and Reverend Howell were going to attempt to stop him.
Gentleman Ghost suddenly got his answer as soon as Supergirl and Reverend Howell appeared. Scowling, he vanished before they were able to attack him.
