How's this for a made-up character... Bit long, but gives you a fair bit to work with.
Name
Ray "Rapier" Shokovitski **
Parents/Family history
Most of Ray's family died during the war (mostly due to human military incompetance rather than a violent kilirathi action). Ray's sister survived the incident and got married, but she and her husband later died from the Nephilim Plague.
History:
Ray earned his nickname (and a scholarship) by submitting the preliminary design for the Rapier fighter, and worked on the design and testing team that put jump drives into the Rapier II. As such he earned the position of being the first man to run a test-jump on the fighter. Unfortunately for him something went wonky on a test-jump and rather than crossing space he crossed time (making him miss quite a number of years). Since his tech skills are now outdated, he's fallen back to his piloting skills to earn a living.
Missing time:
While the fighter he was in shows that his journey forward in time was near-instantaneous, Ray himself appears to have aged approximately five years. He has no memory of those years, neither does the ship' computer, but but both he and it do have several scars that he appearently earned during those years. (Its quite possible he ended up somewhere and spent several years there before someone wiped his memory and tried to return him to his proper place in time... even if that didn't work out right).
Personality:
Ray is, to a degree, a younger human version of the Revenge's Kuklext "Motley" Ragitagha in that he has a strong interest in non-human things (namely, Kilrathi things and Kilrathi ways, and to a lesser degree Firekkan things/ways). He does however remember having "a lot less interest in the cats" before his little time-jump.
Religion
Not a true Sivarist, Ray believes a lot of the Kilrathi religion has been "warped" by too many war-mongers and over-zealous nuts who perverted the true meanings for their own purposes (something that has happened to every religion that ever existed). Ray looks for older, less used/less favored meanings in the Tomes of Sivar, thinking that much of the true higher wisdom and teachings hidden within it have been lost over the years. (so much so that it sometimes bothers Revenge's kilirathi in that he questions things a lot and sometimes even tries to push his "strange interpretations" on them).
Hobbies:
In his spare time Ray tinkers with crude designs hoping to spark the next generation of the Rapier fighter. Maybe he earned some modern money (by putting forth one of the new WC:CD Rapier variations?) when he first returned. He also rebuild/tunes old fighters to sell to museums and collectors, and has an 80% complete WC2 Jalkehi (which he's trying to restore to a factory-like condition but also trying to upgrade for modern use since he likes the physical design). Ray likes to draw architextual stuff like ships, buildings, etc... he's not super-good at it, but sometimes he sells off a rough design sketch.
Fav.Food
Sushi (hey, raw fish is as close as you can get to the raw meat that the kili eat without the food actually making you sick).
** Shokovitszki (not sure of the spelling) is the old Russian/Ukranian version of my actual family last name (from like 3 generations ago)... it got changed to Shokoff (pronouced "show-cough") when my ancestors immigrated to Canada. Depending on which version sounds more "kilrathi like" ... maybe a few of the Renegade's cats even refer to the character as "nar Shokovitski" or some such, like he's tried to hybridize his family name to sound more kilrathi.
