Band from the Disney Channel live action movies Zenon: Girl Of The 21st Century (1999) and Zenon: The Zequel (2001). The movies are based on the young adult novel series Zenon: Girl of the 21st Century written by Marilyn Sadler and illustrated by Roger Bollen. The first one came out in 1997.
In the first movie, set in the year 2049, Microbe is the first band in space! They are to play the space station where title character Zenon Kar (Kirsten Storms) lives and has won a contest to meet hunky, spike-haired lead singer, Proto Zoa (Phillip Rhys). But after witnessing the station being sabotaged, she gets into trouble and gets sent to Earth. She sneaks onto the rocket carrying Microbe into space and saves the day, without even missing the concert (they sing "Super Nova Girl"). In the second movie, Zenon saves the space station AGAIN, in addition to finding the now missing Proto Zoa and making first contact with aliens, who were using one of the band's songs as a distress call. At the end, the band sings the ominously-titled "The Galaxy Is Ours." The rest of the band was played by Paul Reid, Kane Lawton, Craig Terris, and John Corker.
The song "Super Nova Girl" can be found on the Hear PremEar compilation album.
