Al MacKenzie is a S.H.I.E.L.D. agent in the Marvel Comics universe.

The character, created by Bob Harras and Paul Neary, first appeared in Nick Fury vs. S.H.I.E.L.D. #3 (August 1988).

Within the context of the stories, Al MacKenzie was born in Austin, Texas. He was once the C.I.A. liaison to S.H.I.E.L.D. He became romantically involved with Contessa Valentina Allegra di Fontaine after a while, which led to an estrangement between him and Nick Fury. Because of this, he returned to the CIA with the Contessa.

MacKenzie later joined the S.H.I.E.L.D. organization full-time, and spent considerable time as the senior liaison officer to the C.I.A. Subsequently, under unknown circumstances, MacKenzie resigned from S.H.I.E.L.D., and wrote a "tell-all" book entitled UnSHIELDed: an Unauthorized Insider's Look Behind the World's Most Powerful Global Spy Network, which purportedly explained some of the history behind the organization from his point of view. Since then, he also acted as an unofficial source to Ben Urich, prodding Urich and Jessica Jones to attempt to expose Fury's unauthorized mission to Latveria.

Mangler has not been a contender in any CBUB matches.
