With his brother Gary Pleece, he wrote and drew four issues of a self published comics magazine called
Velocity between 1987 and 1989. A satirical collection of stories, there were no recurring characters, but many recognisable caricatures from politics and pop culture. The fifth issue was published by Acme Press in 1990. Their first non self published work appeared in Escape magazine.
Warren Pleece also collaborated with
Woodrow Phoenix on
Sinister Romance, a comic published by
Harrier. He then collaborated with Irish writer
Garth Ennis on the strip
True Faith, serialised in
Crisis and eventually published as a
graphic novel. True Faith sparked some controversy in the UK with an article in the Daily Mail due to its story being critical about Christianity.
Pleece contributed
Second City Blues to the comic
2000AD, which was a series set in a futuristic Birmingham, with teams playing a deadly sport similar to the film
Rollerball.
Pleece has since worked professionally mainly for
DC Comics. He began with a four issue Vertigo series featuring the
Tattooed Man and has since contributed to the
Hellblazer series,
The Invisibles with
Grant Morrison, and
Kinetic by
Kelley Puckett.
