Charest did not initially know how to parlay his drawing ability into a career, as there were no schools where he lived for such an endeavor, and did not foresee it as a profession. as well as many artists from the early 20th century. Charest spent six months continuously producing new sample art and sending them to various publishers, including
Marvel Comics and
DC Comics. He was selling plumbing supplies at the time he got his big break in the comics industry. when DC Comics hired him to provide the art for a
Flash story in ''Showcase '93
#3 (March 1993). Later that same year, he illustrated WildC.A.T.s Special'' #1 (November 1993). He subsequently illustrated back-up stories featuring Voodoo and Warblade in issues 8 and 9 of the regular series (February and March, 1994). He became the regular artist of the series with issue #15, illustrating the title during the runs of writers
James Robinson and
Alan Moore. While his initial work for Wildstorm was characterized by large amounts of
cross-hatching, which was popular among the
Image Comics founders and their imitators, Charest's style began to evolve as he looked to other designers that piqued his interest. His last regular issue on
WildC.A.T.s was #31 (September 1996), though he later returned to illustrate the title's 50th issue (June 1998). He also did many covers and unpublished private commissions. During
San Diego Comic-Con that year, the president of the French publisher
Les Humanoïdes Associés invited Charest to lunch, where he offered the artist the opportunity to work on
The Metabarons. Charest, having long-enjoyed ''
L'Incal'' by
Moebius, had aspired to work for the same publisher, and was "thrilled" by the offer, relating, "I was very young, ambitious and they told me that I could make complete pages, painted, not just drawn in pencil. I was going to live in Paris with my girlfriend, painting all day. 'It will be great!' I told myself." In September 2022, Marvel released
Fantastic Four: Full Circle, an original graphic novel written and illustrated by
Alex Ross, in which Ross utilized for the titular group's uniforms a stylized numeral "4" that Charest had designed in 2013. In the 2024
Expanded Edition of the book, Ross wrote, "Artist Travis Charest had designed a beautiful '4' for an armored suit I saw in his 2013 sketchbook. I sampled his approach and tried to vary it, but eventually, I felt I couldn't improve upon it. Once
Full Circle was moving forward, I asked Travis for permission to use the exact style of the 4 which he generously gave me." ==Technique and materials==
