The Bug was built by research scientist Ted Kord, in the time when he was still president of the Kord Omniversal Research and Development Inc. It was originally constructed from failed experiments and old parts of automobiles and later improved with Ted's new inventions.. After joining the JLI, Kilowog added other improvements that made the Bug far beyond its previous capabilities in terms of technology. Some time later, this bug was destroyed by Doomsday in his first foray against the Justice League..
