Beginning in the mid-1990s, he wrote and drew The Replacement God, a fantasy comic book about a former slave named Knute who is pursued across the fictional land of Mun by a tyrannical king and his beatnik Visigoth Death Horde. The first eight issues were published by Slave Labor Graphics, a subsequent five issues were published by Image Comics, and one issue was self-published by Cannon under his Handicraft Guild imprint.
Cannon worked as layout artist on Top 10, with writer Alan Moore and finishing artist Gene Ha, and pencilled its spin-off miniseries Smax, with Moore and inker Andrew Currie, for America's Best Comics. Cannon won a joint Eisner for Best Continuing Series in 2001 for his work on Top 10.

In 2012 they launched the digital comics magazine Double Barrel, in which Zander Cannon is serializing the graphic novel Heck, his first long-form solo comics project since The Replacement God.
