Little is known about Karnevil. He was sent to Hell for his crimes, but was too much for them to handle. He even claimed that he taught the demons about torture during his stay. He later joined the Pentacle
, as the counterpart to Detective Chimp
. He captured and tortured Detective Chimp, but Chimp escaped. He then beat up and captured Karnevil who was subsequently sent to the Dark Tower
Karnevil was one of the villains stranded on planet Salvation
. He idolized the Joker
. To prove that, he decided to be more like the Joker than the Joker. He planned to turn the Joker's skin into a cape. For a while he acted as the Joker's bodyguard, preventing Bolt
from electrocuting him. When all the villains left the planet, the Joker insulted Karnevil, and left.
Kid Karnevil infiltrated the JSA, posing as the All-American Kid. He claimed that the original All-American Kid was a sidekick to Mr. America
during WWII. He only briefly held the mantle, and was shot in the back soon after by a Nazi, leading for his contributions to the war effort to be all but forgotten. Karnevil pretended to be his grandson, Billy Armstrong, saying that he found a large amount of newspaper clippings and documents in his Grandmother's attic that contained all sorts of information on the original. Devoting himself to becoming the new All-American Kid, he trained hard to become a proficient gymnast of at least Olympic caliber.
Soon after, All-American Kid introduced himself to the current Mr. America, becoming his sidekick and joining the JSA
in the process. Due to space constraints, All-American Kid was placed in a room with King Chimera
. The two didn't get along, mainly due to Chimera's attitude. Karnevil stabbed Michael Holt, the second Mr. Terrific
before hiding the crime. He pretended he had been mind-controlled, and that his mind was wiped to make him forget the incident. Jay Garrick
, using his super speed to re-construct the security system, discovered Kid's actions and the JSA quickly levied accusations against him. He's since been taken into custody by the team. He escaped, hitting Mr. America over the head. He reveals that he was working for an unknown entity, and that his goal all along was to capture Obsidian
, since the entity cannot touch him. Karvevil places Obsidian, who had been severely injured, into a device, completing his mission. However, he did not count on Mr. Terrific's recovery.
