Stringer began his career from the late 1970s with a series of fanzines, many featuring his popular Brickman character; these were read by several professional creators (including Kevin O'Neill, Alan Moore and Dave Gibbons) who encouraged Stringer to try comics as a profession[1] and Stringer recalls that "Alan Moore actually introduced me to one of the editors at Marvel UK – Bernie Jaye who was editor on The Daredevils".
[2] He sold his first professional cartoon to Marvel UK (the British branch of Marvel Comics) in 1983 where it appeared in The Daredevils comic, after which he worked for a short time as art assistant to the cartoonist Mike Higgs (creator of Moonbird and The Cloak).
Prior to Colin joining Transformers, Stringer had written another, similarly slapstick, strip Robo-Capers for that title.
[4] In October 2012 reprints of Team Toxic began to appear in the magazine but brand new stories resumed in January 2014, concluding in February 2019.
[5] Stringer has since self-published other comics that reprint his older material, such as a Derek the Troll / Rock Solid special and a Combat Colin mini-series.
In October 2008 Stringer became the artist on a new strip, Super School which is about five superhero children and their non-superpowered teacher.
