I never created DC canon.
Gentleman Ghost began to smile the minute he was near a jewelry shop and it was near midnight. Superheroes weren't going to defeat him. He remembered occasionally battling Stargirl or Ice. Vanishing if they attacked him with beams of ice or stars from Stargirl's Cosmic Converter Belt.
Concentrating, Gentleman Ghost walked through the door. He approached several valuables and took them.
Gentleman Ghost approached the door at a snail's pace. After he walked through it again, he admired the items.
It was midnight when Stargirl and Ice appeared.
Gentleman Ghost's eyes widened.
Ice and Stargirl attacked Gentleman Ghost. He fled.
