The character of Cameron Chase first appeared in Batman #550 (January 1998) written by Doug Moench and drawn by Kelley Jones.

The series focused on Cameron Chase, an agent of the Department of Extranormal Operations tasked with monitoring and neutralizing metahuman threats to national security.

A New York City resident and former private detective, Chase was recruited by Director Bones, head of the DEO's Northeastern division.

Doctor Trap was in reality Larry Trapp, a man who had lost his girlfriend Caroline Anders due to a public battle between the Justice Experience and their archenemies, the House of Pain, and blamed her death on all involved.

Trap left Acro-Bat's body on the kitchen floor of the Chase family's home, where a young Cameron found it first.

She operated as X-Tract and brought different characters to Earth Omega so that Darkseid can conquer the Multiverse and access the Great Darkness.

An Asian-American Cameron Chase is featured in the Smallville Season 11 digital comic based on the TV series where she battles threats like Prometheus and Felix Faust.
