Similar to other Phantom Zone escapees, Ursa typically never experiences the full measure of her abilities as she is never given enough time to absorb and metabolite the yellow solar energy of Earth's sun before she is defeated and banished back to the Zone. As such, Ursa could prove more powerful than even Supergirl and possibly Wonder Woman as well due to her being a fully matured Kryptonian female while Supergirl is a later adolescent Kryptonian female and Wonder Woman is an Amazon. Her full strength would also make her a sufficient threat to Superman due to her combat prowess.
