As I've found out (and written into HOL), the 'ZZKJ' character really exists in literature: it is taken from a 1953 Alfred Bester novel called "The Demolished Man".
So I strongly believe the man was called a mere Zareh Johannes
Because it fit by coincidence, he crammed the 'ZK' in the middle and adopted the name that, also by coincidence, was identical to that character in the novel.
Talk about Michael J. Fox
whose 'J' middle initial was just by pure invention
BTW: I now have a 100% proof that this 'SAUL' who did the graphics for SHO is indeed Saul Marchese
! Look at this reprint of the Afterburner manual
! Saul Marchese from FOCUS Ltd. And what does the ingame text in SHO say? Yep, Graphics by FOCUS
