Hazlewood came out of comics
fandom, with one of his first published art credits being in
FOOM #4 (1974), the last issue of that
Marvel Comics-published fan magazine to be edited by
Jim Steranko. His self-created character of Deathwatch was a submission to the character contest; it has not been established if the creators of the 1990s Marvel character
Deathwatch were aware of this earlier usage of the name. In 1979, he was published in the fanzine
The Comic Reader. Up through the mid-1980s he had illustration work published sporadically in the
Fantagraphics publications
The Comics Journal and
Amazing Heroes. In
1986, Hazlewood was named the winner of the inking portion of the
Marvel Try-out Book, and from that point forward found regular professional inking work. At first, Hazlewood worked with
AC Comics on such titles as
Femforce and
Nightveil. Next, he inked the entire eight-issue run of
Eclipse Comics'
The Liberty Project. Hazlewood latched on with
DC Comics in 1988 as the regular inker for the new title
Animal Man, written by
Grant Morrison. Hazlewood remained as the book's inker for two years, up through issue #24. During this period, Hazlewood worked for the British company
Fleetway, publisher of
2000 AD, as a cover inker for the title
Psi-Judge Anderson. In the early 1990s Hazlewood freelanced for Fleetway, Eclipse, and
Marvel Comics, and in 1991 became the regular inker on DC's
Adventures of Superman. Partnering with penciler
Tom Grummett, Hazlewood inked that book until 1993. From there he and Grummett moved to
Superboy vol. 3, which Hazlewood inked from 1994 to 1998. Moving into the 2000s, Hazlewood was regular inker on
The Flash vol. 2 from 2000 to 2003. From there, he moved to DC's
Doom Patrol vol.4 (2004–2006), inking
John Byrne for the book's entire 18-issue run. Next, Hazlewood collaborated with
Nicola Scott on DC's
Birds of Prey from 2007 to 2008, and then on
Secret Six from 2008 to 2010. In 2010, writer
Gail Simone from
Secret Six, along with Scott, and Hazlewood, moved to
Wonder Woman for a handful of issues, and in 2010 Scott and Hazlewood moved to
Teen Titans vol. 3. == Personal life ==
