I never created DC canon.
One of Stargirl's eyes widened as soon as she viewed Gentleman Ghost standing within a shop and placing valuables in his coat.
She attempted to consider her options. Run into the shop and aim the Cosmic Staff at Gentleman Ghost. Accidentally blast glass cases with the Cosmic Staff? The same with using stars from the Cosmic Converter Belt around her waist. She refused to imagine replacing what she possibly damaged.
Stargirl wondered if Gentleman Ghost was going to flee from the store. She smiled after she turned to the Cosmic Staff she wielded.
Gentleman Ghost suddenly vanished.
Eyes then widened.
