Very little is known about Jack Ryder. A popular talk show host, he at some point turned from hosting to journalism. Also at some point, and by unknown means, he became the Creeper.
The Creeper was created by Steve Ditko, and first appeared in Showcase #73. The character has undergone several redesigns, and the most recent major reinvention of the character was carried out by Ann Nocenti and Cliff Richards.
In his original origin story, television host Jack Ryder was fired for his overly-confrontational style, and offered a job as an investigator by the head of his network's security. Taking the job, he tried to rescue Dr Emil Yatz, who had been kidnapped by mobsters aiming to acquire his new discoveries in order to sell them to Soviets. Ryder disguised himself in a hastily improvised costume and went to a masquerade ball being held at the estate of the mobster. Recognized as an intruder, he was shot when the mobsters opened fire on him. To save his life, Yatz injected him with a serum that healed his wounds, and that also enhanced his strength and agility. He also placed a device in Ryder's bullet wound which he accidentally left there after the wound closes. They were again attacked by the mobsters, and Yatz was killed. Ryder defeated the mobsters after discovering that an activator device connected to the device in his wound allows him to reacquire his strange costume.
His origin was revised slightly in the Bronze Age; the serum was eliminated from the origin and replaced with two surgically-implanted devices (sometimes given as only one device) that granted enhanced physical attributes. These devices could also recreate objects that had been "imprinted" onto them. The devices were implanted after Ryder was attacked and drugged during an investigation into a group of criminals. The devices accidentally imprinted both the strange costume he was wearing, and the drugs that were in Ryder's system at the time. Any time he transformed into the Creeper, his system is simultaneously flooded with the recreated drugs, inducing his psychosis. This effect grew stronger each time he transformed into the Creeper, as the effect of the recreation was cumulative, but disappeared whenever he returns to the Ryder form. He began to dissociate the personalities from one another, as both the Ryder and Creeper personalities grew progressively disdainful of one another.
In the Modern Age, the Creeper's history was again rebooted and altered so that he became active shortly after Batman's return to Gotham following the Infinite Crisis. Jack Ryder hosted a confrontational left-wing talk show, called You Are Wrong!. One of his interviewees, Dr. Vincent Yatz, created an experimental serum that could be used to regenerate tissue, effectively erasing essentially any injury sustained by the human body. Ryder attempted to steal this serum in order to monopolize the reporting of the new discovery, but failed and was caught. Yatz, in an attempt to protect his serum from mobsters who intended to take it, injected it into Ryder. Soon after, Ryder was shot in the head by the would-be thieves, and left for dead. Instead, however, the serum regenerated his tissue and resurrected him as the Creeper. He easily defeated the villains, and soon discovered that it was possible for him to call forth his superpowered side at will. This origin was later revealed to be an implanted memory, and Creeper was retconned as a half-demon. In this incarnation and all previous incarnations, Creeper had superhuman strength, stamina, reflexes and agility; he possessed an extremely powerful healing factor; his laughter had been shown to have paralytic qualities, and he possessed sharp, talon-like claws on each hand. He wielded no weapons.
The New 52 radically rebooted the Creeper's origin story and powers, with Creeper and Ryder firmly identified as separate entities. Jack Ryder was a television personality working for Morgan Edge. An alcoholic and glory hound, he repeatedly clashed with his coworkers and boss, eventually quitting in a fit of pique. He met the Phantom Stranger in the aftermath, and when Metropolis came under attack by a monster he sought to use the Stranger's powers to bolster his own image. This failed, and he was killed by the monster. Some time later his dead body is possessed by a Japanese Oni, the Creeper. An agent of chaos, the Creeper had crept into the world during the 16th century, and spent some time wreaking havoc in Japan before being killed and trapped in the Soultaker. He was released when the sword was broken. Canonically it appeared that the Creeper and Jack Ryder have met at some point prior to their introduction, however, given that the Creeper was trapped in a sword for several centuries it is unclear how this could have possibly occurred. During this time the Creeper was able to possess the bodies of others, particularly those with weak or corrupted souls. He had limited mind control powers, and was able to force people to carry out terrible actions by whispering to them. He was capable of flight, and was skilled in the use of his chains and scythes as weapons. Vulnerable to sunlight, he had to retreat into a host body during the day. He carried chains which he claimed were a form of penance; he could spin these chains fast enough to create a tornado. The chains were affixed to short scythes.
Following Rebirth, the changes made during the New 52 appear to have been largely reversed, though this is unclear. Creeper and Ryder are once again the same entity, his powers and appearance all resemble the character as he existed in the Modern Age.

The man throws himself and Creeper off of a cliff, but they are rescued. Creeper then joins with a team of heroes who are fighting Eclipso, called the Shadow Fighters. He joins a foray into Eclipso's territory, and is torn to pieces by a pack of possessed hyenas.
