Supergirl has become a young adult, and has grown more powerful this time around, with a new costume and some new witty remarks. Though she was cloned by Dr. Hamilton, and has led an epic battle against Cadmus she still gives her respect to her adopted home Earth.
Supergirl is now a member of the Justice League Unlimited and comes in handy when the league needs her.
Though older and wiser she still is influenced by her older cousin “Superman”.
For prior character development, refer to Supergirl's bio in the Superman The Animated Series's character guide.
