Polaris emerges during the Joker's "Last Laugh" crisis attempting to take control of the magnetic south pole itself, forcing a battle against the Justice League where the League only just manage to defeat him thanks to the actions of Plastic Man (the only League member with no metal on him whatsoever). At the end of Last Laugh, the Slab metahuman prison is moved to Antarctica, as Polaris now is the magnetic pole and cannot be moved. Shortly thereafter, Polaris appears in San Francisco, allied with the villainous Cadre. Here, he is utilizing the power of one of the unimaginably powerful alien Controllers, as well as Cadre member Black Mass, the latter keeping Polaris' magnetic powers in check so that he can move from the Slab. This time, Doctor Polaris has an "altruistic" goal in sight; convinced that civilization and humanity's free will are obstacles for creating a better Earth, he plans to use the Controller's power and some stolen S.T.A.R. Labs equipment to focus his powers and "cleanse the world". The heroes known as the Power Company defeat Polaris by turning the brain-damaged Black Mass against his master and use his gravitational powers to drain Polaris on power. Shortly before the "Infinite Crisis" storyline, Dr. Polaris appears in Metropolis, seeking Superman's help in battling a more powerful and ruthless magnetism manipulator who calls herself Repulse. It eventually transpires that this is a new manifestation of his personality disorder; Polaris is hallucinating Repulse (who looks like the aunt who hated him), and performs her actions himself. Eventually, Superman forces him to accept she is not real. After recovering from this breakdown, Polaris is recruited by Lex Luthor's Secret Society of Super Villains in "Villains United". Dr. Polaris is one of the villains waiting to ambush the Freedom Fighters in a warehouse south of Metropolis in the beginning of Infinite Crisis. When Phantom Lady is impaled by Deathstroke, the Human Bomb becomes enraged. After Dr. Polaris taunts the Human Bomb, he is blown into pieces by the Human Bomb's explosive rage. During the "Blackest Night" storyline, Emerson has been identified as one of the deceased entombed below the Hall of Justice. Neal Emerson appears in the "DC Rebirth". He first appears as part of Max Lord's supervillain team trying to kill Amanda Waller. He is revealed to have been part of Waller's original Suicide Squad. John Nichol A new Doctor Polaris is
