Mike Bellevue is the personification of Microsoft BASIC, a programming language first released for the Altair 8800 computer in 1975. It was the foundational product line of Microsoft, heralding its entry to the personal computer industry. During the home computer craze in the late 1970s and early 1980s, Microsoft BASIC was ported to and supplied with many home computer designs, with slight variations to add support for machine-specific functions, especially graphics.


Mike's early concepts date back to 2017 and designed by SpacePuffer in 2019, making him the oldest UNIVER.SYS character by design, and has barely changed until now. In other words, Mike's creation singlehandedly started the development of UNIVER.SYS.


As the eldest, Mike serves as a mentor figure to early Logiciel TANs such as Nix, Amy, and others. He loves tinkering with code and programs, and has written his own books about programming, which he has distributed to different companies. Although he may appear reserved, Mike is very protective of his successors and will do anything to support them, and encouraged them to pursue their ambitions.

Due to his independent spirit, the older TANs may perceive his way of thinking as irreverent or even blasphemous. Even though Mike prefers to deal with conflict logically, he is not above asserting himself and standing up against opposition. In the 1980s, Mike grew to be more active rather than being behind-the-scenes due to Logiciel's growth as a major Ensemble, although he can be nostalgic about his early days as a hobbyist TAN in the 1970s.


  • Mike's name is from Microsoft itself.
  • Trey’s order for Mike to crack down on his software distribution is based on Bill Gates’ “An Open Letter to Hobbyists” in 1976, which expressed his dismay for piracy, especially on Altair/Microsoft BASIC.
  • Mike’s ability to write software books and manuals for many Ensembles is derived from the many variants of Microsoft BASIC available for different platforms.
  • Additionally, Mike’s offbeat sense of humor is derived from DONKEY.BAS, and awkward BASIC game for the IBM PC.
  • Mike's actual birthday was unknown, but it's widely agreed that it's April 4, the same day his home company was founded.
