Sometimes, when I'm kitbashing, I have a definite idea what I'm trying to make but often I just playing around with no idea. There are those wonderful, organic kitbashes where everything just seems to work and then you sit back and try to work out what it is you've actually made. This was one of those cases. A while ago I made this chap;
Then he sat in a drawer ...
Now he's finally starting to get some paint and an idea is forming about who he is. He's still a long way from finished. I'm calling him the Quartermaster, though I don't have an actual name for him yet. He is the one who keeps the weapons and equipment of the ship's crew and he cannot resist tinkering with them, like a far future version of Q from the Bond movies.
Neither FW or GW make rules for spaceship crews and I doubt they ever will, so I'm going to use the Inquisition rules for my crew. The Inquisition is perfect in that it allows me to have a collection of the weird and wonderful that still feels human, far more so than any other published codex. With the Quartermaster I realised I could get a (counts as) Jokaero into the crew. Jokaero's are physically weak but can shoot powerful weapons so the Quartermaster is an old man and his weaponised servo skull provides a rational for his ability to shoot.
