Jhonen C. Vasquez (born September 1, 1974) is an American comic book writer, cartoonist and music video director.
 He is best known for creating the comic book "Johnny the Homicidal Maniac", with its spin-off comics "Squee!

I Feel Sick is a "doubleshot", full-color comic book written and drawn by the comic artist Jhonen Vasquez and colored by Rosearik Rikki Simons (who also voiced GIR in "Invader Zim").
 It revolves around Devi D. from "Johnny the Homicidal Maniac" (JTHM), and her dealings with the same supernatural and/or psychological forces that drove Johnny to lunacy.
 Originally intended as a single paperback, it was later split into two issues so as to avoid compromising the length of the story.
 It was published by Slave Labor Graphics.
 Vasquez stated that the creation process of "I Feel Sick" was cathartic.
 The problems Devi had while working for NERVE and neglecting her own work was reminiscent to the pressure Vasquez had while working on "Invader Zim".
