Mort became Editor-in-Chief of Cracked magazine in the 1980s, where he worked with veteran cartoonists while also giving opportunities to emerging creators including Daniel Clowes and Peter Bagge. During his tenure, he brought longtime MAD artist Don Martin to Cracked. Mort also created and edited the cult horror and comics magazine Monsters Attack!, collaborating with creators including Steve Ditko and John Severin.

In the 1990s, Mort worked at Marvel Comics and launched the Marvel Music imprint, combining comics with popular music and working on projects involving KISS, the Rolling Stones, Rob Zombie, AC/DC, Bob Marley, Elvis Presley, and other recording artists. Across his career, he wrote, drew, colored, edited, and published comics featuring characters including Superman and Spider-Man, while also producing illustration, animation, film, television, and music-related work. His animation credits included projects for Sesame Street, Disney, and MTV.

In later years, Mort continued publishing through Comicfix and was active in preserving and reviving classic comics material. He worked extensively with Steve Ditko during his career and, near the end of his life, served as Creative Director and Editor-in-Chief of DitkoVerse, working with the Steve Ditko Estate on projects celebrating and expanding awareness of Ditko’s work.

At G-Man Comics, Mort colored Steven Butler’s cover for the first issue of Simon N. Kirby: The Agent. His contribution remains part of the visual history of the G-Man Universe.

Mort died at his home in Portland, Maine, on August 24, 2025, at the age of 63. He is remembered for an extraordinarily varied creative career and for his enthusiasm for comics, popular culture, and the artists with whom he worked.
