Metamorpho (Rex Mason) is a superhero appearing in American comic books published by DC Comics. Created by Bob Haney and Ramona Fradon, the character debuted as the lead feature in The Brave and the Bold (January 1965). Originally an adventurer, he was converted into a metahuman made of several different elemental substances after being cursed by an ancient artifact while on an expedition. He is a founding member of the Outsiders, and has also joined multiple incarnations of the Justice League.

Anthony Carrigan portrays the character in the DC Universe (DCU), beginning with the film Superman (2025). Additionally, Tom Sizemore, Scott Menville, Adam Baldwin, and Fred Tatasciore have voiced the character in animation.

Creation

In a 2013 interview with Comic Book Resources, Fradon spoke on the character's genesis stating,

Publication history Metamorpho's creator, Bob Haney, had seen success with DC Comics in 1964 with the titles Metal Men and Doom Patrol, featuring bands of superheroes exhibiting fantastic powers. Under the editorial management of George Kashdan, Haney was asked to capitalize on these titles' popularity with a similar character. Metamorpho debuted in The Brave and the Bold #57 (January 1965).

As first conceived, Metamorpho was a parody of the fantastic characters that populated comic books in the 1960s. Artist Ramona Fradon was coaxed out of maternity retirement to illustrate Metamorpho's first appearances. The popularity of Metamorpho's appearances in The Brave and the Bold led to a 17-issue ongoing series between 1965 and 1968. Metamorpho also appeared in two issues of Justice League of America (#42 and #44), but did not join the eponymous group and became a reserve member.

Metamorpho appears on the cover of Aquaman #30 as one of the pallbearers (along with Batman, Hawkman, and Superman) at the "Sea King's Funeral". Metamorpho also appears in a series of backup stories in Action Comics #413–418 and World's Finest Comics #218–220 and #226, #228 and 229.

In 1975, Metamorpho appeared in 1st Issue Special #3, a brief anthology series consisting of one-shots. That issue was written by Bob Haney and illustrated by Ramona Fradon, Metamorpho's creators. Haney and Fradon had met at the 1974 San Diego Comic-Con, and while reminiscing, it emerged that both of them regarded Metamorpho as one of the features they most enjoyed working on, leading them to ask DC if they could do one more Metamorpho story together. Fradon later commented: "I think we both felt that Metamorpho was our baby. I never had an experience like I had working with Bob Haney on Metamorpho. It was like our minds were in perfect synch ... it was one of those wonderful collaborations that doesn't happen very often".

After becoming a charter member of the Outsiders in 1983, and member of the European branch of the Justice League International, Metamorpho received his own four-issue mini-series in 1993. In 2005, DC Comics reprinted Metamorpho's early The Brave and the Bold appearances and the entirety of the 1965 series as one of the company's volumes of Showcase Presents. In 2007, Dan Jurgens launched the six-issue series Metamorpho: Year One.

As part of Wednesday Comics, Neil Gaiman wrote a 12-page Metamorpho story that Mike Allred illustrated. In 2016, Metamorpho starred in the anthology series Legends of Tomorrow alongside Firestorm, Sugar and Spike, and the Metal Men.

In 2024, Metamorpho received a new series, Metamorpho: The Element Man, as part of the DC All In initiative, which lasted for six issues. It was written by Al Ewing and illustrated by Steve Lieber.

Fictional character biography Rex Mason is an amoral adventurer and mercenary who is hired by Stagg Enterprises CEO Simon Stagg to steal an Egyptian artifact, the Orb of Ra. Shortly after hiring him, Simon Stagg learns that Mason has been secretly dating his daughter Sapphire Stagg. This and other incidents begin to fuel in Stagg a dislike for Mason that ultimately leads to a plot to kill him.

Inside the pyramid where the Orb is hidden, Mason is knocked unconscious by Simon's brutish bodyguard Java and exposed to a radioactive meteorite from which the Orb of Ra was fashioned, transforming him into Metamorpho, the Element Man. Shocked by Mason surviving, Stagg instead manipulates him to do his bidding by using the meteorite's energy to threaten him. Later, it is revealed that Ra created Metamorpho and similar beings to help him battle his mortal enemy, Apep.

Metamorpho, unlike most super-humanoids described in DC Comics, does not possess a fully human appearance. Similar to the Marvel Comics character Thing, he considers himself a "freak" and wishes only to be restored to his former human state, rejecting an offer of membership from the Justice League in Justice League of America #42 because of this. Green Lantern attempts to change him back using his power ring but is stopped by a "yellow" component of the meteorite radiation.

Metamorpho briefly has a crimefighting partner named Urania "Rainie" Blackwell, a woman who deliberately exposed herself to the Orb to gain its powers. She calls herself Element Girl (nicknamed "the Chemical Doll") and works with him on a number of cases.Metamorpho #10 (February 1967)

Issues #16–17 were intended to show a new direction for the series, with Sapphire marrying a man named Wally Bannister and Metamorpho joining a mysterious Mr. Shadow to deal with an immortal queen. Bent on world conquest, the queen (an exact lookalike of Sapphire) marries Metamorpho. She later steps outside her mystic city and instantly ages 2,000 years. When Wally Bannister is murdered by Algon (a metamorph who has lived for centuries in a depowered state), Metamorpho is framed. Instead of coming to his defense against the false accusations, Metamorpho's colleague Mr. Shadow comes forth as an enemy. It is revealed that Mr. Shadow was attempting to enslave Metamorpho all along. Metamorpho is tried and convicted by a jury of rabble and is then executed.

Element Girl revives Metamorpho, and Algon, the real murderer, is killed by molten lava in an attempt to regain his burned-out powers. It is later learned that Mr. Bannister's murder was engineered by the villainous Prosecutor, who is then killed by an insectoid villain. At this point, issue #17 ends, and the story is never continued.

Metamorpho reappears years later in The Brave and the Bold #101 (April–May 1972). It is revealed that Metamorpho had spent the period after the end of his own series immersed in a chemical bath concocted by Stagg in an attempt to cure his condition. Stagg retrieves him from this "cure" early because he needs Mason to save Sapphire. Metamorpho stars in a new backup series beginning in Action Comics #413 (June 1972). There is no reference in this revival series to the events or characters of the last two issues of his previous series.

Urania Blackwell, unreferenced since the end of the regular series, is later revealed to have ended her partnership with Metamorpho when her unrequited attraction to him became too much for her. Blackwell's powers are removed at her own request by Ra, resulting in her death; the episode, in Neil Gaiman's Sandman, involves Death of the Endless. Death mentions Algon's death in passing, trying to convince Blackwell that she will not live forever.The Sandman (vol. 2) #20 (October 1990)

Justice League Metamorpho spends some time with the Justice League, including Justice League Europe. During this period, he encounters Sapphire Stagg again.Justice League Europe #5 (August 1989) He becomes involved in a battle with the Metal Men, who have been tricked by Simon Stagg. His League friends, Rocket Red and Animal Man, are at the site of the battle, but are being detained by Java. After the battle, Metamorpho learns he had a son with Sapphire, but the baby boy's touch harms all but Sapphire and Metamorpho. When Java holds the baby, his arms melt. Metamorpho hands the baby over to Simon, who immediately fears he will be affected like Java was moments before and die. However, something in his genetic structure protects him, just as it did with Sapphire. Simon's stance softens and everyone is set free. Doc Magnus, the leader of the Metal Men, offers his services in creating new arms for Java. On the way home, Metamorpho's friends are puzzled as to how he knew Simon would be unaffected by the child. Metamorpho indicates that he hoped the baby would kill Simon.Justice League Europe #12 (March 1990)

Later, Metamorpho has a romantic relationship with Crimson Fox, which is cut short by her apparent murder. His personal investigation of the incident uncovers multiple layers of lies and deceit. During his time with the team, while fighting the planet-smashing aliens called The Family, Metamorpho is hit by a powerful energy blast that destroys his body. He later reforms his body with a new appearance.Justice League International (vol. 2) #61 (February 1994)

Third death and return When the Hyperclan attack the Justice League of America's orbiting base, destroying it, Metamorpho protects three of his teammates, Nuklon, Obsidian, and Icemaiden, in a giant, fluid filled ball.
