When he first appeared in Micronauts #1 (dated January 1979), Bug was known as Galactic Warrior, taking this name from a figure from the Micronauts toy line on which the comic book series was based. The toy based characters were all owned by Takara Co., Ltd., with any original characters owned by Marvel. Starting with the fourth issue Galactic Warrior's name was changed to Bug. This was done after Marvel realized that since the character's design looked nothing like the toy, they could assume ownership if they used a different name.
Bug appeared as a featured character throughout Micronauts original run, starting from the first issue until issue #59 (dated August 1984), the series' final issue. Months later Marvel restarted the series with Micronauts: The New Voyages #1 (dated October 1984) with Bug once again appearing as a featured character. This second series lasted until issue #20 (dated May 1986).
Planned relaunch and solo one-shot
In the 1990s Marvel began plans to launch a new series starring the Micronauts, despite the fact that they no longer held the publishing rights to the toy based characters. Assuming that Abrams Gentile Entertainment (the company that, at the time, owned the American rights to the Micronaut toy line) would agree to this new series, Marvel hired Shon C. Bury to write the series and Cary Nord to draw it.  In preparation Bug and the other Micronauts that Marvel owned guest starred in Cable #39 (dated January 1997) and Bug was featured in a solo one-shot (dated March 1997). The negotiations with AGE eventually fell apart, the series was shelved and the three issues already produced were never published.
Bug would later appear with the other Marvel owned Micronauts (now named the Microns) in issues of Captain Marvel in 2000 and 2001.
Bug did not make any further appearances until 2007. At this point he appeared alone, without any of the other Microns, as a prisoner of the alien race the Kree. He was then recruited into a hastily assembled covert team led by Star-Lord. His activities at this point were depicted in the limited series, Annihilation: Conquest - Star-Lord and in the subsequent limited series Annihilation: Conquest. He was then a recurring character in the second volume of Guardians of the Galaxy, which spun out of the events portrayed in Annihilation: Conquest.
Although Bug was not a founding member of the "modern" Guardians team, Rocket Raccoon asked him to join when the original group disbanded after some internal misunderstandings. Bug agreed, and fought alongside the Guardians as they attempted to stop the Shi'ar-Kree interstellar conflict known as the War of Kings. Although they failed, Bug stayed with the Guardians as they dealt with the war's aftermath in the Realm of Kings storyline through the series' end with issue #25 in 2010. Bug appeared as a member of the Guardians in Avengers Assemble issues #4-8 in 2012.
