Lori Lemaris is a fictional character in DC Comics' Superman comic books. Lori is a mermaid from Tritonis, a city in the undersea lost continent of Atlantis.
Silver Age History
While attending Metropolis University, Clark met Lori, who was attending as a student and hiding her mermaid identity by posing as a wheelchair-using student (with a blanket covering the lower half of her body). Clark and Lori soon fell in love with each other, but Clark started to wonder why Lori would repeatedly cut their dates short every night to return home at 8 p.m. Clark eventually decided to propose marriage to Lori, but Lori told Clark that she couldn't marry him, and that she also had to return to her native country. Heartbroken, and growing suspicious of why Lori had to return home every night at a preset time, Clark investigated, and discovered Lori's mermaid secret. Lori, in turn, revealed that thanks to her people's telepathic powers, she knew that he was really Superman all along, but promised to keep the knowledge of his identity a secret. Lori also stated that since the two came from such different worlds, they could never be wed. After a parting kiss underwater, the two bid farewell to each other. ("The Girl In Superman's Past")
Lori made various appearances throughout the Silver Age Superman comics. Like many other minor DC characters, Lori was killed in the 1985 limited series Crisis on Infinite Earths.
Lori was soon brought back in a new incarnation after John Byrne's 1986 Man of Steel limited series, which revised Superman's origins. Her post-Crisis incarnation first appeared in Superman (volume 2) #12 in December 1987. Lori's post-Crisis origin story and her relationship with Clark remained similar to the original, except that post-Crisis, Clark had not yet adopted a superheroic identity at the time he was in college. Additionally, in the modern version, Lori also had a mission to discover other cities of the continent of Atlantis, a quest completed when Superman later met Aquaman, who revealed he was a native of just such a city.
In Lori's appearances in the mid-to-late 1990s, Lori had been magically altered so that she would be human when dry and a mermaid when wet, much like Madison, Daryl Hannah's character in the 1984 movie Splash. Lois Lane agreed to let her stay at her apartment for a while during a trip to Metropolis; however, Lori being an old flame of Clark's put a brief strain on Lois and Clark's relationship, though things were soon straightened out. Lori remained a recurring character through the rest of the 1990s, and made an appearance in Justice Leagues, a recent Justice League of America comic event involving her native Atlantis. In human form, her feet do not touch the ground, instead floating about an inch above it.
Lori was thought to be killed in the 2005-2006 Infinite Crisis limited series when the out-of-control Spectre destroyed the kingdom of Atlantis. She appeared again after the Crisis' reality-altering events in a flashback story shown in 2007's Superman Confidential #6-7.
In Tangent: Superman's Reign, the Tangent Earth's version of Lori Lemaris appears. She is no longer a mermaid, and is now the woman who became The Joker, a superhero on Tangent-Earth. She was incarcerated for years under Superman's reign.
