Fabok graduated from St. Clair College’s Tradigital Animation program in 2007. He then attended the Word of LifeBible College in Owen Sound for a year, an experience that furthered his interest to pursue a career as a comic artist. After becoming aware that legendary illustrator David Finch lived in his same town, Fabok sent him his portfolio. Finch agreed to mentor him and put him through a six-month-long "boot camp", teaching him everything from anatomy, to backgrounds and buildings. After six months Finch suggested Fabok sending his new portfolio to DC Comics. His first published work were issues #70 and #71 of Superman/Batman. He subsequently penciled the full 2011 series of Aspen Comics's Soulfire, his only work outside of DC Comics to date. Fabok's bigbreak in the industry happened when David Finch asked him if he was available to pencil issues #4 and #5 of Finch's own mini-series '. Within two weeks DC had offered Fabok a two-year exclusive contract. After drawing the first annual for Scott Snyder's Batman, Fabok became the regular artist of the freshly relaunched New 52 run of Detective Comics with issue #13. He ended his stint on the book with oversized anniversay issue #27. Fabok went on to draw several issues of weekly limited seriesBatman Eternal, among an all-star team of pencilers that included Dustin Nguyen, Guillem March and Mikel Janin. Following a one-off drawing the annual for Justice League International, in 2014 he succeeded Doug Mahnke as main artist for Geoff Johns' Justice League, from issue #36 to issue #50. In 2016 he also penciled the first issue of Justice League vs. Suicide Squad. The following year he illustrated both the Batman issues of the Batman/Flash crossover The Button, which served as a teaser for Geoff Johns' Watchmen sequel Doomsday Clock. In 2018 Fabok provided art for Tom King'sSwamp Thing one-shot The Talk of the Saints, featured in the Swamp Thing Winter Special, which went on to win an Eisner Award for best short story. The same year he collaborated with other top DC artists on Brian Michael Bendis' The Man of Steel mini-series, which served as the prelude for Bendis' Superman relaunch. He also reunited with writer Geoff Johns for a mini-series focusing on the three Jokers that inhabit the DC universe. After several delays the three-issue prestige-format mini-series ' will be released in August 2020.
