"Dazzler was originally a project commissioned by Casablanca Records in the mid-to-late 1970s to be a cross-promotion in the mold of KISS, who had two successful comic book tie-in super-specials by the end of 1977. Marvel Comics would develop a singing superhero, while Casablanca would produce a singer. The two companies would then work with Filmworks and produce a tie-in motion picture; Marvel Comics Editor-in-Chief Jim Shooter wrote a treatment for the project.
The character was originally conceptualized as "The Disco Queen" with the power to make people tell the truth. Initially, no one wanted anything to do with the project. Marvel Comics appointed former Archie Comics writer Tom DeFalco to the character and he developed some changes to the character, namely suggesting light-based powers. Roger Stern conceived of the character's name, Dazzler, while John Romita, Jr. provided pencils."
"Artist John Romita, Jr. originally intended for the character to resemble model, actress, and singer Grace Jones, as seen in early depictions.However, representatives from Filmworks – wanting to promote model and actress Bo Derek – insisted on design changes to reflect Derek's features.
To promote Dazzler, Casablanca wanted it cross-promoted within several key Marvel Comics titles: The X-Men, The Fantastic Four, and Spider-Man in particular, with Dazzler debuting in The Uncanny X-Men because she was a mutant character. However, Casablanca continued to request conceptual changes to the character's appearance and personality, leading to several cancellations of the project. Eventually, Casablanca Records backed out of the Dazzler project altogether due to financial concerns. Marvel Comics, left with a much-publicized new character, decided to launch the project as a monthly series.
According to writer Tom DeFalco, Dazzler was canceled "five or six times" prior to its launch in March 1981. At the time, Marvel Comics was looking for other filmmakers to invest in a Dazzler cross-promotion. However, Jim Shooter and Stan Lee decided to launch the series without such a partnership because of their "faith in the character.""
