Blackjack was a bank robber who dressed like a 30s-era mobster. He took his name from the Old West criminal "Blackjack" Ketchem. He had sandy-brown hair and a scar that ran diagonally from his left eye to below his right eye. His face typically held a manic, wide-eyed grin.
Blackjack had a fanatical obsession with Dick Tracy that was a combination of hero worship and rivalry. To that end, he went on a bank robbery spree across the country to build his reputation before he finally arrived in Tracy's city.
Tracy's Biggest Fan
Upon Blackjack's arrival in the city, the FBI sent Special Agent Fritz Ann Dietrich to aid Tracy in apprehending the bank robber. When Tracy and Major Crimes Unit trapped Blackjack and his men in the Whole Sum Bank, the robbers escaped by using a zip line from the roof across the street to another building. There, they had a snow plow waiting to help them escape into a snowstorm.
Tracy pursued Blackjack and his gang on a snowmobile, and Blackjack refused to allow his henchmen to shoot Tracy. Blackjack finally agreed to surrender himself and his men in exchange for Tracy placing his fedora on a fire hydrant and allowing Blackjack to put a bullet hole through it. Blackjack held to his end of the agreement, vowing to return once he was out of prison.
The hat then joined the others that Tracy keeps on a display of bullet riddled fedoras from his many shootouts. Blackjack had succeeded in his goal of gaining a place in Dick Tracy's history.
In January 2013, Blackjack called Tracy to inform him that he had escaped from jail, taking care not to harm anyone in the process. Blackjack enthusiastically promised Tracy that their paths would cross again after Blackjack had practiced more.
Blackjack aided Tracy when the detective had been kidnapped and placed in a death-trap by Abner Kadaver. Blackjack freed Tracy's daughter Bonnie and uncle Ray (whom Kadaver had taken hostage), notified Sam Catchem of where Tracy could be found, then observed Tracy as he proceeded through Kadaver's traps. Blackjack distracted Kadaver as the killer was about to attack Tracy and shot the sword cane out of his hand (December 30th, 2013), allowing the detective to gain an advantage.
Blackjack then went into hiding. He reportedly sent flowers to Stiletta Jones' funeral.
Blackjack returned to his earlier practice of robbing banks that he believed to have engaged in immoral or unethical practices. At one such bank, he encountered Dick Tracy, who allowed Blackjack to escape. Blackjack later met Sparkle Plenty at another bank, and persuaded her to come see his collection of Sparkle Plenty memorabilia. After posing for a few photos, Blackjack allowed Sparkle to leave.
Blackjack later helped Tracy rescue 2 people from a bank that had been set on fire by its corrupt manager. This earned him Dick Tracy's thanks, but Blackjack was still taken into police custody.
Some time later, Blackjack's collection of Dick Tracy memorabilia was stolen by an unknown thief. Blackjack learned about the theft, and broke out of prison to recover his property. He attended the Dick Tracy exhibit at the Gould Library where he encountered fellow Dick Tracy collector Mr. Bones. The two men had a cordial interaction, though Bones eventually revealed to Blackjack that he was now in possession of Blackjack's collection (which he offered to return).
Bones betrayed Blackjack and drugged him when they met at Bones' hideout. Bones then impersonated Blackjack and arranged a meeting with Dick Tracy. Bones left Blackjack tied up in his shack which was filling with gas. Bones assumed that that Blackjack would asphyxiate or be killed in an explosion. Blackjack revived and was able to call the authorities to warn Tracy. Bones' shack then exploded, apparently with Blackjack inside.
Tracy questioned whether Blackjack survived, but Blackjack was later shown alive and leaving the city on a bus.
- Part of Blackjack’s modus operandi was to play the song “Tubthumping” by the musical group Chumbawamba during his robberies. He used the song to control the timing of the robberies, and it became his unofficial theme song.
- Blackjack made a point of not harming people during his robberies, and only stealing from the banks which he considered corrupt.
- Tracy's snowmobile pursuit of Blackjack was reminiscent of his earlier chase with the first Chameleon.
- At the conclusion of the Abner Kadaver deathtrap storyline, Blackjack was not shown returning to jail. It is unclear if Tracy made Blackjack's involvement a matter of public record. It was implied that Tracy allowed Blackjack to flee, though this would be uncharacteristic of the dedicated lawman since Blackjack was still a wanted felon.
- Dr. Chaplin, a member of the Rogues' Gallery Cosplay Club dressed as Blackjack for their Dick Tracy-themed event, as seen in a 2018 Minit Mystery. He killed fellow club member Dr. Eugene Roche, who was dressed as Dick Tracy.
