Liz Allan was a high school student at Midtown High School and a minor love interest of Peter Parker and
Flash Thompson. Peter likes Liz, but she is Flash's girlfriend and considers Peter something of a loser, even taking part in the general ridicule that Peter endures on a daily basis. Her earliest appearances depict her as flighty and rather thoughtless - not outright cruel, but lacking the empathy necessary to perceive Peter's nature. However, after she hears an ailing Peter had donned a Spider-Man costume to save
Betty Brant from
Doctor Octopus, she develops a crush on him. By this time, however, Peter's interest has waned considerably, as he notes that Liz never showed any real interest in him until he began dating Betty Brant, and assumes that Liz's feelings are little more than a schoolgirl crush. Betty and Liz clash several times over Peter, as Betty mistakenly thinks that Peter reciprocates Liz's interest in him. In
Amazing Spider-Man #28 (September 1965), Peter and Liz graduate from high school. At the graduation ceremony, Liz admits her feelings to Peter, and says she accepts the fact that her feelings are unrequited. In the same issue, Spider-Man battles the
Molten Man, who in later issues is revealed to be Liz's stepbrother, Mark Raxton. She does not appear for a few years, during which time Peter developed relationships with
Gwen Stacy and
Mary Jane Watson. When Liz returns, she dates then marries
Harry Osborn, whom she meets at Betty Brant's wedding to
Ned Leeds, becoming
Liz Allan Osborn. The couple have a son,
Normie Osborn. Their family history turns tragic, however, after Harry Osborn has a mental breakdown. In the guise of the
Green Goblin, Harry kidnaps Liz, Normie, and Mark, and terrorizes them within an old family mansion. Liz is deeply traumatized by this experience and falls into a state of denial about her husband's problems. Harry's madness leads to his death shortly after. Struggling to put Harry behind her, Liz breaks ties with Peter and Mary Jane. In the
graphic novel,
Spider-Man: Legacy of Evil, Harry attempts to pass the legacy of the Green Goblin down to Normie Osborn, but fails due to the efforts of Spider-Man, Mark Raxton, and
Ben Urich. Later, Liz Allan became a supporting character in
Daredevil, serving as a love interest for lawyer
Foggy Nelson. The couple breaks up after
Mysterio manipulates Foggy into having an affair in a plot to drive Daredevil insane. Liz feels like Foggy has let her down and ends their relationship. After Spider-Man publicly reveals his real identity in the "
Civil War" storyline, Liz becomes resentful of him, blaming Peter for bringing so much death into their lives. However, after the events of the "
One More Day" storyline, the public revelation of Peter's identity has been forgotten and Harry is seemingly still alive, but he and Liz are no longer married. Liz and Normie are present when Molten Man is given an antidote to his condition. Mark Raxton, who had escaped the basement in which Liz was keeping him for his own safety, is cured thanks to
Oscorp. Liz is last seen attending a party to help Flash Thompson deal with the loss of his legs. During the 2011 "
Fear Itself" storyline, Liz is seen trying to leave New York with her son, due to the fear and chaos that is happening, and encounters bank robbers. Liz Allan forms a new alliance with
Norman Osborn as he attempts to re-establish himself as a corporate figure - apparently using an alias as his activities as the Green Goblin have made his true name too public, working with him to ensure her son's future. Following a confrontation between
Spider-Man 2099 and an agent of a time-travel organization from 2211 in the Alchemax Building, Liz has deduced that the 'new' Spider-Man must work in the company and is determined to enlist him to her cause, foreshadowing the time-traveler's claims that Liz Allan and Spider-Man 2099 will have some significant impact on future history. Liz then appears as the CEO of
Alchemax when
Eddie Brock enters her office and brings her an experimental dinosaur he captured. She reveals that
Stegron is responsible and makes a deal with Brock: she will help him find a cure for the
Venom symbiote while he deals with Stegron. During the
Cult of Carnage arc, Liz bonds with portions of the
Anti-Venom and
Carnage symbiotes, transforming her into Misery. She helps battle the Zombiotes during the "
Venom War", using her Anti-Venom abilities to kill them. ==Powers and abilities==
