I never created DC Animated Universe canon.
Stargirl glanced at the starless sky before she frowned. She recalled eating her mother's tuna casserole many minutes earlier. Viewing the empty streets. She began to wonder if any crooks were going to appear.
Stargirl's blue eyes settled on a man after the latter fled from a jewelry shop. They were wide for a split second.
Frowning another time, Stargirl used the Cosmic Staff she wielded to fly and pursue the crook. She paused with him as soon as two cop cars appeared. She started to glance at the sky another time.
One smile replaced Stargirl's frown by starry skies.
