He really takes the name too far. Introduced in Venom (Vol. 2) #1 by Rick Remender and Tony Moore, boy known only as Jack was kidnapped by the Crime Master (Brant), who raised the boy in assassination with the boy becoming devoted to him. To prove his loyalty, Jack was sent back to his parent, who he killed with remorse. It was during this event that he developed his signature of scooping out the contents of the heads and placing a candle in them, thus earning him the name of Jack O’Lantern. He would kill all the previous people who have used the name.

He first became known to the superhero community when he was sent to kidnap Doctor Ekmecic and clashed with Agent Venom. After Agent Venom confiscated Crime Master’s Antarctic Vibranium, Crime Master learnt of Venom’s real identity and sent Jack to kidnap Betty Brant. Venom saved her by handing over the AV. Jack later kidnapped Venom and Crime Master forced the agent to go on a mission for him. The job was to kidnap the Toxin symbiote but when the Venom symbiote saw it, it went berserk and attacked Jack. Overwhelmed, Jack managed to escape by promising not to attack Flash’s family.

Crime Master then gathered more villains alongside Jack to form the Savage Six to defeat Venom. They kidnapped Betty and his family. Venom hunted Crime-Master down and was about to kill him but couldn’t go through with it since it was discovered he was Betty’s long thought dead brother. Betty shot him dead to save Flash. Jack on the other hand had gone on a killing spree. Venom tracked him to the sewers where he discovered that Jack had dug up Flash’s father’s body and set it to explode. The two would clash and it looked like Jack was winning until Flash shot him with his father’s gun. Jack was sent to the Raft but escaped.

Magneto later recruited him to stop Red Onslaught and was inverted into a hero. He later helped stop the X-men from blowing a bomb in New York and return being a villain after. He later battled Deadpool and later Venom (Brock this time) before undergoing surgery and therapy to live a normal life. Growing bored of this, he returned to being a villain. Following Deadpool to Wakanda, he would fight Black Panther and Deadpool, who killed him by blowing off his head. Sent to Hell and turned into a demon, he would try and take the throne from Johnny Blaze. He would make a deal with Lilith and was sent back to life. There he attacked the new Jack O’Lanterns and Danny Ketch, believing him to still be a Ghost Rider. He soon discovered that Ketch had become a Spirit of Corruption and was quickly sent back to hell.

Jack has always been considered a knock off Green / Hobgoblin. This version of Jack gained more prominence when he quickly became a fan favorite during the Agent Venom series. As such he would receive a ML as part of the Spider-man Absorbing Man wave.
