Crazy-Quilt is the name of several characters in DC Comics. The first version, Mr. Quilt, is an enemy of the Boy Commandos and later Robin. The second version, Paul Dekker, is an enemy of the Blackhawks. The third version, also named Paul Dekker, is an enemy of the Post-Crisis Batman and Robin. The fourth version is an unnamed female who was a member of Alexander Luthor Jr.'s Secret Society. The first and third are blind and use special helmets that enable them to regain their vision and generate rainbow energy beams. Crazy Quilt also appears in Batman: The Brave and the Bold, voiced by Jeffrey Tambor, and the DC Super Hero Girls franchise, voiced by Tom Kenny.

Mr. Quilt, the original Crazy-Quilt, first appeared in Boy Commandos #15 (May-June 1946) and was created by Joe Simon and Jack Kirby. He first encountered Robin in Star Spangled Comics #123 (December 1951).

The first Paul Dekker incarnation of Crazy Quilt appeared in Blackhawk #180 (January 1963) and was created by artist Dick Dillin and an uncredited writer.

The Post-Crisis version of the original Crazy Quilt was first seen in Detective Comics #566 (September 1986) by Doug Moench and Gene Colan. At first, his real name was not mentioned, but in Batman: The Widening Gyre #4 (February 2010) he was given the name Paul Dekker rather than Mr. Quilt.

The unidentified female version of Crazy Quilt first appeared in Villains United #2 (August 2005) and was created by Gail Simone and Dale Eaglesham.

Crazy-Quilt was originally a painter named Quilt 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. However, he is blinded by a gunshot wound after one of his henchmen betrays him. Quilt volunteers for an experimental procedure to restore his vision, but is left unable to see anything but bright colors. In his second published appearance, he regains his vision using a special light-emitting helmet. After five published encounters with the Boy Commandos, Crazy-Quilt faces Robin for the first time.

In Earth-One continuity, Crazy-Quilt's history is identical to the Golden Age version. Crazy-Quilt's sight is restored briefly after he kidnaps a surgeon to assist him. Batman and Robin intervene, during which Crazy-Quilt is blinded again after Robin reflects his light beams at him. Obsessing over his young adversary, he becomes one of the few bat-villains to hate Robin more than his mentor.

Attempting to enact revenge upon Robin, Crazy-Quilt mistakenly takes out his aggression on Jason Todd, nearly killing him. He later fights Jason again after knocking Batman unconscious.
