Rex Mason, known as “The Element Man” or Metamorpho, is another of DC Comics’ fictional superheroes. His creators were Haney and artist Ramona Fradon in 1964. They based it on the ideas of George Kashdan. Metamorpho is one of the founding members of the Outsiders.

Who is Metamorpho?

Quién es el Metamorpho y quién lo interpretará en Superman: Legacy?

Metamorpho is famous for possessing a unique ability to transform his body into any periodic table element. He can turn specific body parts into tools or weapons against others.

His origins go back to an adventurer hired by Simon Stagg, a business tycoon, to recover an artifact called the Orb of Ra in Egypt. Unaware of the risks, Rex exposed himself to the radiation emanating from the Orb, which turned out to be a meteorite.

But, Rex was not the only Metamorpho, but one of many created by “Ra”, the sun god. His mission was to serve as a warrior in his battle against the god APEP, called “The serpent that never dies”.

Unlike other super humanoids, Metamorpho could not fully assume his normal human appearance. For Rex, his powers stemmed from an illness, hence his quest for a cure. He wished to return to normalcy, hence his refusal to join the Justice League of America.

Metamorpho Publication History

Metamorpho was part of the characters that were present in the ’60s. A founding member of the Outsiders group, he has had different affiliations with superhero groups.

The Metal Men and the Doom Patrol, by Bob Haney, inspired the superhero. For this, he called in artist Ramona Fradon, and they brought The Element Man to life.

Metamorpho was introduced in issues 57 and 58 in 1965 in The Brave and The Bold magazine. That gave rise to the superhero having his own series. The series had 17 editions, in which Joe Orlando, Jack Sparling and Sal Trapani participated as cartoonists.

Likewise, he participated in issues 42 and 44 in the Justice League of America series. Metamorpho was the second superhero who refused the invitation to join the Justice League. But, he was a reservist in the crossover between the Justice League and the Justice Society.

The superhero is present on the cover of Aquaman, carrying the coffin at the “Funeral of the Sea King”. He reappeared after the end of his series in The Brave and The Bold 101. He teamed up with Batman and carried out several of his adventures.

By 1974, Fradon and Haney reunited and asked DC Comics to do another Metamorpho story. As a result of this work, in 1975, another storyline by the same authors reappeared. It was published in the magazine’s 1st Special Issue, in issue number 3.

Metamorpho was not so popular, but even so, in 1983, he appeared in The Brave and The Bold and 40 of DC Comics Presents, appearing in issues 123 and 154. The superhero was part of the Outsiders team. That allowed him in 1993 to have his own four-issue miniseries.

Trying to relaunch old superheroes, DC Comics decided in 2005 to reissue the superhero in black and white. Specifically, they edited the 17 issues of Metamorpho’s 1965 series, The Brave and the Bold.

In 2007, Metamorpho: Year One appeared, written and drawn by Dan Jurgens. The miniseries consisted of 6 issues, which completely reinvented his origin. Likewise, in 2016, Metamorpho was the protagonist of the anthology series Legends of Tomorrow.

Metamorpho’s Fictional History

Rex Mason’s story begins by showing the adventurer hired by Simon Stagg. This scientist and tycoon, the owner of Stagg Enterprises, is interested in recovering a strange Egyptian object called the Ra Orb.

After hiring Rex, the scientist learns he is dating his daughter, Sapphire Stagg. That unleashed uncontainable anger in Simon, generating an aversion towards Rex, which ended in a plot to assassinate him.

Java, Simon’s bodyguard, knocks Rex unconscious. Then, Rex exposes himself to the radioactive meteorite which formed the Orb of Ra. An explosion transforms Rex into Metamorpho. 

Then, the fictional story of Metamorpho goes through several phases such as:


Once he obtained his powers, the origin story of the adventurer Rex Mason continued. He did it alone until Batman called him to form a group alongside other heroes. The mission was to rescue Lucius Fox, Bruce Wayne’s friend.

When they succeeded, the group decided to stay together and called themselves Outsiders. Among their team was Dr Jace, who advised them and investigated how to return Rex to normal. After discovering a method, he summoned his girlfriend Sapphire Stagg to a meeting.

But, the girl’s father, Simon Stagg, killed Rex with the Orb of Ra. The doctor has no choice but to declare him dead. Consequently, her team members went to Egypt to locate the Ahk – Ton meteorite; they wanted to save him.

The Outsiders were transported to 1200 B.C. and again exposed Rex to the meteorite, managing to restore him. But, with this second exposure, Rex could no longer revert to his human form, remaining permanently as a Metamorpho. Upon returning to the 20th century, Rex asked his girlfriend to marry him, who accepted.

Justice League

Between his adventures, Metamorpho spent time in the Justice League, including the Europa chapter. He reunited with Sapphire Stagg, and his father, who tricked the Metal Men, entered the scene again. They ended up involved in a battle against the superhero.

In his previous stage, he did everything possible to have a child with Sapphire. But he discovered he had that much-desired baby at the end of this battle. That baby had a typology like his father’s, so it can affect others, except for his father, mother and grandfather.

Sometime later, Metamorpho had a romantic relationship with Crimson Fox. That relationship ended badly, as people thought Fox was dead. However, her investigation showed otherwise.

In the end, in a fight against aliens, the superhero was hit by a powerful energy blast. The blast destroyed Metamorpho’s body, and he formed something completely different. He wears this new look until he disappears again.

Third death and return

Metamorpho protected his teammates, the Icemaiden Nuklon and Obsidian, while the Hyperclan attacked and destroyed the orbital base of the Justice League of America.

The three of them and Metamorpho crossed the Earth’s atmosphere, but the superhero died. Id temporarily resurrected him. Only later, Sapphire Stagg brought him back to life using Orb Ra.

Then, in an accident with Simon Stagg’s experiment, Sapphire, Joey, and Simon became one energetic being. That caused Metamorpho to adopt both the form and personality of Java. Thanks to Canary’s help, he could return to his original shape.

Outsiders / “Shift”

Metamorpho continues to appear in the Outsiders series (vol. 3). In this plot, the superhero was “a regrown fragment of his own body”. That is, he had formed a twin. Because of this, Rex tried to reassimilate him, but the Outsider team convinced him to let the twin lead his own life.

His twin assumed the name “Shift” and strengthened his relationship with Indigo. When she passed away, the twin became depressed. After a year, the twin voluntarily reassimilated into Metamorpho. What they didn’t know was that Shift had murdered several. 

Thus, it fell to Rex to step in and take Shift’s place in the Outsiders. Shift’s crimes are in Outsiders Vol. 3. Incredibly, he had inadvertently murdered 44 people. That occurred during Black Lightning’s escape from Iron Heights Penitentiary.

Metamorpho in The New 52

The New 52 reinvented the plot, revealing that the Outsiders survived. Metamorpho was the one who saved them with the same technique used to rescue the Justice League. He was one of the candidates to form the new Justice League International but was not selected.

DC Rebirth

Metamorpho is in the Watchmen sequel, Doomsday Clock. The superhero is in the news as a “Superman Theory”. It showed that the government was experimenting on humans to give them superpowers.

As part of his macabre plan, Simon Stagg, transmuted Metamorpho into Nth Metal. With this, he sought to open the portal to the Dark Multiverse. The superhero fought and tried to get Simon, Plastic Man, and Mister Terrific to close the portal. In parallel, Plastic Man protected everyone else from the energy emanating from that multiverse, to which he was immune.

The four arrived at a lifeless world, encountering Phantom Girl, who had been trapped there for some time. Thus, they found a computer and received a hologram of Tom Strong. Strong told them that they needed them to save the universe.

Metamotpho’s Powers and Abilities

Metamorpho is one of the few superheroes who can transform his body at will. For this, he uses a variety of elemental compounds of nature. Initially, he was limited to the natural elements immersed in the human body.

But, as time passed, this limitation vanished, and he could form and combine compound elements. Thus, this superhero can assume liquid, gaseous or solid forms.

His abilities are not limited to his entire body; he can mold specific parts whenever possible. Metamorpho can make shapes as complex as a tank or as simple as a spring.

That is how Rex possesses natural body armor on his body. He manages to resist damage, energy attacks, or blunt attacks. His abilities and powers make him an ideal partner in the fight against evil.
