Barr spoke in an open letter to fans on the creation of the character stating, "When it was decided to put The Outsiders into their own book, a new member was obviously called for.

I began kicking around ideas, and conceived a female character who possessed mental powers (an area covered by none of the other outsiders).

[2] Emily Briggs was a bank teller who lived with her husband in Gotham City before being kidnapped by the people of Abyssia and rescued by the Outsiders.

She eventually became one of the hosts of the television program The Scene alongside Vicki Vale, Tawny Young, and Linda Park.

[6] In Infinite Crisis, Oracle recruits Looker, among other heroes, to defend Metropolis from Alexander Luthor's army.

[9][10] She later joins a new incarnation of the Outsiders sanctioned by Batman Incorporated before they are seemingly killed in a satellite explosion orchestrated by Talia al Ghul.

[13] An alternate reality incarnation of Looker named Model Citizen appears in Justice League: Crisis on Two Earths, voiced by Kari Wührer.
