Alexander ''Alex'' Luthor Jr. is a fictional character appearing incomic books published byDC Comics. The son ofEarth-Three'sLex Luthor, he played a large role in theCrisis on Infinite Earths andInfinite Crisis events.
Created byMarv Wolfman andGeorge Pérez, the character made his first appearance inCrisis on Infinite Earths #1 (April 1985). He had a prominent role in that series, and appeared 20 years later as one of the two primary antagonists of the sequelInfinite Crisis, alongsideSuperboy-Prime.
Alexander Luthor Jr. is born onEarth-Three, the son ofLex Luthor andLois Lane.[1] Luthor Sr. is Earth-Three's only hero, fighting theCrime Syndicate (an evil version of theJustice League of America). InCrisis on Infinite Earths, theAnti-Monitor destroys Earth-Three and countless other universes with anantimatter wave. To save their son, the Luthors place him in an experimental device which carries him toEarth-One.[2]
TheHarbinger takes Alexander in at the request of theMonitor.[3] Alexander's passage through the anti-matter storm grants him power over both matter and anti-matter, accelerating his aging. By the end ofCrisis, Alexander has aged into a young adult over the course of several weeks.[4] After the Monitor's death, Alexander helps lead the heroes and villains of the DC Universe against the Anti-Monitor.[5][6] After defeating the Anti-Monitor with the help of theEarth-Two Superman (Kal-L) andSuperboy-Prime, Alexander reveals that he has saved Kal-L's wife, theEarth-Two Lois Lane, from being erased from existence. No longer having a place in the post-Crisis universe, the four retreat to another dimension.[7]

Alexander watches the events on the post-Crisis Earth for several years with his companions, and eventually convinces a pessimistic Kal-L to escape their dimension.[8] Alexander tells Kal-L and his cousinPower Girl that they can help him bring aspects of Earth-Two into predominance over the merged universes, which will help Earth-Two's Lois Lane recover from her current illness.[9]

Alexander masquerades as Lex Luthor and forms a new incarnation of theSecret Society of Super Villains, who he has construct a dimensional "tuning fork" from the remains of the Anti-Monitor to recreate themultiverse.[10] However, the tower is destroyed in a battle between Superboy-Prime andSuperboy (Conner Kent).[11] Alexander flees toGotham City, where theJoker mutilates and kills him.[12][13] Following his death, Alexander returns on two occasions. He returns as aBlack Lantern inBlackest Night and is temporarily resurrected by theGreen Lantern of theTangent Comics universe inJustice League of America (vol. 2).[14][15]
Alexander Luthor Jr. possesses a genius-level intellect and is a master manipulator. The circumstances of his escape from Earth-Three give him power over matter and antimatter, which he can use to generate energy bursts and dimensional portals.[16] He also has a form ofprecognition, enabling him to foresee the most probable events.
