The Micronauts are a ragtag team of heroes from Microspace. Originally a small-time crew of smugglers aboard their ship, the Heliopolis, they found themselves drawn into the conflict between Baron Daegon's Ministry of Science and Baron Karza's Ministry of Defense. They are now stuck on a strange, mysterious world populated by giant creatures and even bigger machines.
The team that would become known as the Micronauts were a group of smugglers consisting of Space Glider Phenolo-Phi, a first-gen Acroyear, a Microtron unit, and Pharoid Oziron Rael. They were hired by Hezlee Ferro to steal a pack of medical supplies from a Ministry of Science Valcitros station. Ferro assigned his security agent Larissa to accompany them on the job. When the Micronauts arrive at the station, they find it protected by numerous sentry-bots that attack them upon arrival. After unsuccessfully trying to fight off the sentries, the crew flees to a room storing a Biotron unit. Oz gets in the Biotron, which tells him that there isn't any medical supplies on the station. The station was actually developing a biological weapon. Before Oz can order a retreat, a group of Phobos units attack, blowing a hole in the station and causing the Micronauts to go flying.
After flying into the entropy storm, the Micronauts were attacked by Reptos, a race of beings previously thought destroyed by the cloud. Before the Reptos could destroy the Heliopolis, the crew was saved by the mysterious Time Traveller.
Several days into their journey, Microtron scanned the surrounding area looking for something to fuel the Heliopolis, detecting something "big". The Micronauts then received a message from Baron Karza. Karma told them that though it has only been a few days for them years have passed for Karza. Microtron then informed Oz that he discovered the source of the energy he detected, as well as the source of Karza's signal. Oz struggled to comprehend and Karza explained that "it" was the birthplace of Microspace: the body of Micronus Prime.
