Tech Jacket was a six issue American comic book created by writer Robert Kirkman and artist E. J. Su, published monthly by Image Comics in November 2002 to April 2003. The book is a part of Kirkman's overarcing Image Universe, which is anchored by Invincible, but also includes such heroes as Savage Dragon, Shadowhawk and Superpatriot. A Tech Jacket-wearer (looking similar to Zack Thompson's) was seen fighting Omnipotus with a cadre of fellow heroes in Invincible #27 also fighting an alternate Invincible in "The Invincible War". The Geldarians were shown to be part the Coalition of Planets in Invincible #23; It was revealed there that the Kresh were charged by the Viltrumites to overtake Geldaria. In Brit: Old Soldier, among the bonus sketches Robert Kirkman states that Brit, Capes, Tech Jacket, and Invincible all take place in the same universe.
