Shazam's attack was more than effective. It sent Starro reeling back, and subdued much of its army. It appeared Starro's psychic connection was like a hivemind, if they could eliminate the big starro the others will fall as well. Starling was already gathering herself as Nightwing was attempting to rally the others. Now was the time to attack, while Starro was at its weakest. But seeing as how she can't fly or shoot lightning out of her fingertips, she'd leave Starro up to the heavy hitters. "I'll keep the small fry off your backs, just finish off the big guy" she told the others, turning her focus to the weaken Cobi. She didn't know if she could kill him, even in his current state, but she was ready to play cat-and-mouse long enough for the others to do the real work.
