Test Subject Name Generator

A test subject's name does a lot of work in fiction: it tells the reader that a person has been reduced to a line in a ledger, and the moment they choose a real name for themselves is often the turning point of the story. Stranger Things' Eleven, Portal's Chell, Mass Effect's Subject Zero and the numbered children of countless secret-program plots all follow the same logic. The designation is cold, the nickname is human, and the gap between them is the character.

Real labs use a predictable grammar you can borrow: a role word (subject, specimen, patient, candidate, participant, donor, host), a number that may be padded with zeros or broken into groups, and an optional letter, Greek letter or phonetic-alphabet word to mark the batch or arm of the study. Secret-project fiction adds a codename layer on top, so a subject belongs to Project Nightjar or the Lambda cohort, and clinical language contributes control arms, placebo groups, cohorts and rechallenges that sound chillingly procedural when applied to a person.

The list mixes all of these: bare numbers and spelled-out numbers, Greek and NATO designations, Roman numerals, alphanumeric serials, project codenames with a subject number, descriptive labels like the Boy in Tank Nine, and pairs that put the official designation beside the name the subject actually answers to.
