Supergirl

Kara Zor-El was the only survivor from Krypton's sister planet, Argo. While exploring the sector of space once occupied by Krypton, Superman discovered a hidden cryogenic facility which had sustained heavy damage. Only one chamber was intact, containing the last survivor of Argo: Kara. Taking the young woman back to Earth, Superman introduced Kara to his adoptive parents The Kents took her in for three years, isolated from the world at large under Clark's instructions, in the guise of Jonathan Kent's teenaged niece.

Eventually, inspired by her "cousin" Clark, Kara made a costume similar to Superman's and occasionally joined on missions as Supergirl. Kara frequently visited Clark in Metropolis and, as Supergirl, she had full access to Superman's Fortress of Solitude In Supergirl, Superman found a living link to his alien heritage, and someone he could talk to about his dual lives as Superman and Clark Kent. She became a frequent friendly ally who could be trusted with Superman's secret.

At one point, Supergirl started to have disturbing dreams in which she chased and incinerated men she had never seen before. She contemplated the possibility of those so-called dreams being in fact suppressed memories while she was under the government's custody. Supergirl, Green Arrow, and the Question set off to investigate this strange occurrence. They went to S.T.A.R. Labs, where Professor Hamilton assured her that she was under their care and vigilance the entire time, and that her dreams may be an expression of her traumatic experience.

While leaving, the trio got attacked by robots and soldiers that linked them to the U.S. Army, and more specifically to General Hardcastle. They confronted him and he admitted to having being in charge of government experiments in metahuman and mutant studies, but he couldn't explain Supergirl's dreams. The Leaguers connected Hardcastle to Nuvo-Gen, so Supergirl and Green Arrow went there to investigate. They ascertained that Supergirl's DNA was used to create a clone, whom they trained to be a living weapon. Supergirl deduced that they shared some sort of psychic link that made her see her clone's actions. Supergirl and Green Arrow were lured into a hologram-training room, where the clone, referred to only as 'Tea', attempted to kill Supergirl and thus erase their psychic link, from which Supergirl's conscience and morals was holding her back.

Supergirl fought her off, until the entire facility blew up, seemingly destroying Galatea.When Supergirl found out that it was Hamilton who cloned her under Cadmus's sanction, she was set to take them down. However, when trouble arose and the JL core members turned themselves over to the government, Supergirl was left in charge of the League. While the heroes where struggling to get the power back online, Galatea and an army of Ultimen invaded the Watchtower. Supergirl tried to stop Galatea from overloading the reactor, but she was overwhelmed by her clone's superior strength. Supergirl stalled Galatea long enough for the reactor to reboot, whereupon she used one of its cables to electrocute her doppelganger, finally defeating her.
