From Spy vs. Spy III - Arctic Antics +: "Nike has left Danish Gold and formed a new group called 'Triton T'". So there's only one Nike (I think you agree on this, Jan). Keyboarder has some scroll text by Henrik, mentioning "Claus B. Jensen (my big brother, [...]". Keyboarder also mentions the game (working title "trazers", later to be changed, see below) that Henning, Claus and Henrik are working on, with Henning as coder, Claus as graphician and Henrik as musician. Music for Masses mentions that "megaman, dosman and nike" are working on a game which "has changed name, [...] because a little lamer called himself 'trazer'". This indicates that Henrik, Henning and Claus are indeed (in random order) Megaman, Dosman and Nike. Music for Masses also states that Megaman is the big brother of Nike. Combining this information, we have that Nike is Henrik Buus Jensen, the musician Megaman is Claus Buus Jensen, the graphician Dosman is Henning Andersen, the codician.
