Crazy Quilt is an unnamed noted painter who leads a double-life as a master criminal. He gives the plans for his crimes to various henchmen through clues left in his paintings. His criminal empire crashes to a halt when one of his henchmen double-crosses him. Blinded by a gunshot wound, he volunteers for an experimental procedure that restores his vision, but is unfortunately left unable to see anything but bright colors. In his second published appearance, this is combined with a special helmet that emits bright colored lights, enabling him to see under most circumstances.
In a 1963 issue of Blackhawk taking place on Earth-One, a fence named Paul Dekker impersonates Crazy Quilt, but the title heroes expose the impostor. As a result of this appearance, some resources report the original Crazy-Quilt's true identity as Dekker. This includes at least one comic, the Kevin Smith-penned Batman: The Widening Gyre #4. However, the earlier Batman Encyclopedia, another official source endorsed by DC Comics, states that Dekker is a separate character from the original Crazy Quilt.
In the Post-Crisis, Paul Dekker's history is similar to the Earth-Two Crazy Quilt. Crazy Quilt's sight is restored briefly for a time after he kidnaps a surgeon to assist him. Batman and Grayson intervene. In self-defense, Robin reflects the madman's light beams back into his newly restored eyes. Unintentionally, Quilt is permanently blinded. Obsessing over his young adversary, he becomes one of the few bat-villains to hate Robin more than his mentor.
Later, thinking to enact his revenge upon Grayson, he mistakenly takes out his aggression on Jason Todd, who was new to the role at the time. Todd is nearly beaten to death. Again, it is Robin who is pivotal to stopping Crazy Quilt's plans.
Crazy Quilt later fought Jason Todd after knocking Batman unconscious.
When Ra's al Ghul caused a mass prison break at Arkham Asylum and Blackgate Penitentiary, Crazy Quilt was among the freed inmates that worked for Ra's al Ghul by abducting Alfred Pennyworth, Commissioner James Gordon, Vicki Vale, Harvey Bullock, and Julia Pennyworth.
Crazy Quilt was later seen in Arkham Asylum when Batman was Arkham Asylum's latest patient. He joins the other inmates into attacking Batman who ends up defeating them.
During the Underworld Unleashed storyline, Crazy Quilt was among those who were offered a Candle of Neron.
Crazy Quilt appears in the Belle Reve riot in Justice League #34, lugging around the eviscerated body of the prison warden. The prisoners, along with much of humanity, were being affected by the entity Mageddon. It had affected fellow prisoner, telepath Hector Hammond, who then altered the minds of the inmates.
Crazy Quilt also has a role in one of the many reincarnations of the Secret Society of Super Villains. He and dozens of villains gather in response to the JLA's new moonbase and extended team efforts. During the meeting, Quilt has his outfit insulted by the Monocle. The meeting turns out to be a JLA trap and all the villains are captured.
In The New 52 (a reboot of the DC Comics universe) during the story arc Batman: Endgame, Dr. Paul Dekker appears as the person Batman suspects supplied the Joker with his newest serum, but is found out to not be guilty. He is also a member of Doctors Three along with Doctor Death and Hugo Strange. Dekker calls out claiming that the Joker has given him the opportunity to become one of the Dionysian men as well and gleefully injects himself with a syringe despite Batman's warnings. Almost immediately, Dekker's tissues begin to decay and rot from his body and he drops from the window into the waiting crowd of infected who tear what remains of him to pieces.
In a nod to his Pre-Crisis alter ego, Dekker is found covering his nude body with a patch-work quilt.
Apparently the Society, led by Alexander Luthor, Jr., has in its roster a new version of Crazy Quilt, a female one with the characteristic costume and vision-helmet of the previous villain. She has appeared in the 'Villains United' series. She works with many other supervillains to take down the 'Secret Six'. In Outsiders #50, she is captured by the Suicide Squad.
In the Secret Six series, she is one of the villains who accepts the offer of a bounty on the heads of the Secret Six from mysterious crime boss, Junior. She is possibly shot by the Six, and stabbed in the stomach by Scandal.
She later appears in James Robinson's Justice League: Cry For Justice mini as one of the many villains who attacks the team.
Crazy-Quilt has a helmet that allows him to hypnotize his victims using flashing lights of various colors. It can also project lethal laser beams, blinding lights, and functions as artificial eyes since his own eyes no longer function; the lenses feed their input signal straight into his brain.The Paul Dekker version of Crazy Quilt is featured in Batman: The Brave and the Bold voiced by Jeffrey Tambor. He has a non-speaking cameo in the episode "Trials of the Demon" where he is shown robbing the Gotham Art Museum until he is defeated by Batman, and is taken away to Arkham Asylum. In "Night of the Huntress," he is shown amongst the inmates trying to escape from Blackgate Prison. Crazy Quilt plays a major role in the episode "The Color of Revenge" where he tries to get revenge on Robin for blinding him back when he and Batman worked together. He escapes to Blüdhaven, robs S.T.A.R. Labs, and builds a giant laser cannon to kill Robin and destroy Blüdhaven. He is defeated by Batman and Robin and is taken back to Arkham.
The Paul Dekker version of Crazy Quilt appears in DC Super Hero Girls, voiced by Tom Kenny. He is a teacher at Super Hero High.
Crazy Quilt appears in The Lego Batman Movie.
Crazy Quilt is mentioned briefly in Batman: Arkham City.
