TechJacket

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.

Zack Thompson, a high school kid, finds a dying alien from a race of incredibly intelligent but physically weak beings called the Geldarians. To make up for this they have invented the Tech Jacket, a vest that every Geldarian is equipped with upon birth. Seeing the human and knowing his crashed spaceship is going to blow up and kill them both, the alien fits him with the Tech Jacket, saving his life.

But now the Tech Jacket can’t be removed and gives Zack “the most powerful weapons in the universe”. Removal is unpermitted, under executive decree 574-3. The vest gives him near-invulnerability, super-strength, flight, energy blasts, and a variety of weapons. The jacket also has an ability known as Host Maintenance which when activated removes and destroys all germs, bacteria and dirt from the user’s body
