Oswald Loomis, alias the Prankster, was a TV host turned Superman villain.

Oswald Loomis was once the popular host of the "Uncle Oswald Show," a WGBS-TV early morning children's program. Oswald Loomis unleashed a host of dangerous pranks upon Metropolis when ratings and cancelation cut short his comedic career. Dubbing himself the Prankster, he set about playing dangerous practical jokes targeted at Metropolis and its citizens.

Loomis even held Lois Lane hostage and even tried to marry her. When Morgan Edge intervened, he was hurled out of a trap door 30 stories high. Superman managed to save Morgan Edge and freed Lois Lane before Loomis surrendered. The prankster then escaped his guard out of fear of going to prison.[2]

Oswald Loomis later returns a younger, more athletic body after selling his soul to Lord Satanus. His personality was also changed; he no longer wanted to just joke around, but has now become a manic trickster with the desire to make the world laugh via his own twisted way. When Metropolis was upgraded by Brainiac 13. Oswald Loomis takes advantage of the futuristic technology by creating high gadgets and weapons, while retaining a comical theme. Oswald Loomis challenges Superman again as he was suffering from Kryptonite poisoning during the battle, and is hospitalized in S.T.A.R. Labs shortly thereafter.[3] He later escapes and attempts to attack Superman while he is being treated for kryptonite poisoning, stealing the latest armor of John Henry Irons and posing as Steel when Irons is being shrunk down by the Atom to investigate the cause of Superman's illness along with Superboy and Supergirl, but Irons is able to follow them in a bulkier, less advanced suit and disable the stolen suit after Prankster identifies himself, although Loomis is able to escape.[4]

When the Joker took over the earth, he was Joker City's only exorcist, who still acts as childish as ever, but now wears a Halloween mask. Here, Loomis's goal is to expel the evil from those who still believe in science, John Henry Irons in particular, which the Joker has practically destroyed while wielding the 5th Dimension powers of Mister Mxyzptlk.

He is one of the various super criminal sent to to the penal colony on the planet Cygnus 4019, which has been nicknamed Salvation.[5]

The Prankster was among the many of criminals who was caught and placed in the Phantom Zone by the people of Kandor. Superman freed Prankster to be taken to Belle Reve.[6]
