When Lego randomly gives a number onto a Lego set name (Like Super Nova 2, Star Hawk 2, Star Defender 200), it just invites MOCers to build their own versions and enlarge the number. Paulo Carreira, a person after my own heart, has built a Super Nova III, an upgrade on one of the smaller Blacktron ships.
In the builders own words: "This was build to commemorate the 16th Anniversary of my LUG, Comunidade 0937, where we had to make a Redux of a LEGO set or wooden toy produced in the last 90 years. Of course I had to go for a Blacktron II vehicle since they're the coolest faction ever produced by LEGO." Well, at least one person agrees with me.
