Sci-Fi Surname Generator

Surnames for spacers, colonists, megacorp execs and rogue AIs: clipped hard-consonant coinages (Vexyl, Korova, Daxon), recognisable Earth names with a twist (Reyes-Vox, Sato-9, Mendez-Ka), and a few that just sound like they belong on a starship hull.

About these names

Synthetic surnames combine a sharp prefix with a tech-y suffix: Vex + ix, Kor + ova, Dax + on.
Hyphen / number suffixes hint at clones, registries or corporate lineages: Sato-9, Reyes-Vox.
Keep some names plausibly human (Calder, Halloran, Voss) so a crew roster feels real, not all-robot.
Pair with a sci-fi first-name list and a ship name and you've got an instant away team.
