SCIFI races inspired by the undead

Ghost: you are not the original you. They had their brains broiled in the destructive uploading that created an exact duplicate of their soul in silicon. You are not that duplicate either, no you are a copy of a copy of a copy. Your soul is housed in a cheap plastic drone. You have a holographic projector that can laser excite motes of dust into a holographic facsimile of the person whose memories fill your silicon brain. You can fly and interface with the ships technology but the people who manufactured you didn’t deign to give your drone body hands.  

Skeleton: The cryopods failed. Most everyone else is dead, they died aeons ago. Those who remain are like you. Your flesh is gone now you are metal bolted to bone, an extensive network of prostheses giving direction to skeletal limbs. Your brain is gone now and the neural implants that store your half remembered life rattle in your hollowed out skull.

Ghoul: You were once a machine. Designed to keep the ship in glorious working order. Time has taken its toll though and factories that once manufactured some of the parts you were designed to use were destroyed. If you couldn’t repair yourself you couldn’t repair the ship. There wasn’t any other choice really. Dense chords of muscle flex your metal limbs and neurons fire in your wetware hard-drive as you go to harvest more meat from the not-passengers. You are a machine no longer.

Mummy: People weren’t designed to live this long, you became quite certain of that at the ripe young age of a thousand something or rather, it has been a loooong time since then. You are one of the original crew of the ship and you have grown bored. Still the thought of offing yourself still seems repulsive to you. And so the claustrophobic medical machines you rely on pump their dry nanite dust through your withered veins, sustaining you for yet another day. Perhaps it's time to shake things up again, you really could use some excitement.

Vampire: Greetings security android no_<ERROR: NUMBER IS TOO LARGE IN INPUTFIELD>, and welcome to your tour of service.
