Extremists: Part 2 – Written by Steve Orlando. Art by Felipe Watanabe and Scott Hanna. Cover by Ivan Reis and Joe Prado. Believing heroes to be threats to the survival of any world, Lord Havok and the Extremists have already murdered the mightiest heroes from their home dimension. To save our Earth they’d kill thousands more, starting with the newly formed JLA. But eye-to-eye, are Havok’s and Batman’s goals that different? Billions of lives depend on the answer.
