Tech Jacket is an American comic book series that was created by writer Robert Kirkman and artist E. J. Su and published by Image Comics. It ran for six issues from November 2002 to April 2003. A backup series was also published that continued the storyline from the original series. Both series have a large fanbase and are well worth reading.
The story centers on the Geldarians, an intelligent and powerful race of humanoids who are physically weak. To combat this weakness, the Geldarians invented the Tech Jacket, a vest with infinite power. When fully developed, a Tech Jacket is considered to be the most powerful weapon in the universe. When Zack Thompson obtains a Tech Jacket, he must learn that with infinite power, comes infinite responsibility.
