Catwoman #77 (2008)

Catwoman flies through the air, punching Batman's helicopter and causing it to explode. She saves Batman from the explosion even though he's tried to kill her twice. She knows he isn't the same Bruce, but still it's hard to see him beaten and battered... She tells him to bring friends the next time he feels the need for a rematch, and leaves. She goes to Meg's Daily Grind and buys a chai tea from the waitstaff, who are terrified of the infamous mass murderer. She doesn't have any money on her, so the barista tells her it's on the house. Catwoman sits on the roof, drinking her tea, questioning whether she should even try to leave this world, which she names "Earth Whatever", where she's the biggest bully on the playground and return to a planet full of supervillains. Her thoughts are interrupted by the Justice League of Earth Whatever, who think she's their reality's Catwoman. She could clear up the confusion, but she decides to fight them instead. She easily takes out the strongest people in the universe, then she takes out the cigar the Joker gave her to celebrate. She notices how strange it is that it's unbroken after everything that's happened to her on Earth Whatever, but she smokes it anyway. Lex Luthor is observing the body of Catwoman, floating in suspended animation. He thinks he heard her make a noise, but he dismisses it as a neural spasm. Catwoman is a vegetable now, he decides as he walks away. Martian Manhunter, hiding nearby, frowns. On Earth Whatever, Selina searches for more information on her recent deceased equivalent, but instead she finds the name "Kyle, Helena" in the phone book. She can't believe it's her daughter, but she knows it is. She is interrupted in her search by even more members of the Justice League and related groups, but Martian Manhunter appears again to tell her none of it's real. He tells her she's caught in a machine on Salvation, and it is showing her a world where she can do anything to trick her into staying. He shows her how this world's Batman doesn't move when she isn't focused on him because without her, he doesn't exist. Neither does Helena. Catwoman pokes Batman, and he crumbles into pieces. She remarks that real or not, this place was happier. She took on the Justice League, and she could take on their friends too. She asks Martian Manhunter how to break out of the stasis generator. He tells her all she has to do is want to leave, and so she does. She wakes up in the same room she was in before. She walks out onto the surface of Salvation and decides it's time to do what she did on Earth Whatever out in the real world--she's going to take control of her own life. She finds Captain Cold, Joker, Giganta, Clayface, Mirror Master, and Mr. Freeze in the middle of a duel, and she thinks, "Sure you're still stuck on a planet a billion miles from Earth, surrounded by psychos, monsters, and run-of-the-mill bastards, but how bad can it be?"
