Metamorpho (Rex Mason) is a superhero appearing in American comic books published by DC Comics. He was created in 1965 by writer Bob Haney and artist Ramona Fradon. Metamorpho is a founding member of the Outsiders, and has also joined multiple incarnations of the Justice League. The character has been moderately popular since his introduction in 1965. Originally adventurer Rex Mason, he is converted into a man made of a shifting mass of chemicals after being cursed by an ancient artifact that he has retrieved. 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, the Element Man, 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 during this time in two issues of Justice League of America (#42 and #44) and became the second superhero to decline an invitation to join that organization (Adam Strange being the first), though he did become a reservist, eventually being called in during a Justice League/Justice Society crossover to help find and rescue the Seven Soldiers of Victory. 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 #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'd 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
