Had a Star Wars character before that group imploded.
She was a 13 year old human girl with a droid arm. Not just a robotic prosthetic, but a "droidified" cybernetic arm, with an astromech brain. I had no pilot skill, but my arm did. Anyway, I was a thief and a tech head, and a bit of a punk kid. Lived in the shell of a junked tramp frieghter (before Rey made it cool lol).
We played a handful of sessions, and through story events she had repressed memories returned to her that revealed that she was force sensitive, had been caught stealing a "valuable art object" from an imperial (a Hand of The Emperor or something, didn't get to find out exactly), and the lady stabbed her arm with the object, which made her start halucinating and getting sick, until a Jedi in hiding found her, cut her arm off, healed her up best he could, gave her a basic cybernetic arm, and smuggled her to another planet, and then repressed her memories.
And then we never played again.
I also have several NPCs that started out as PCs, but campaigns changed hands, and now I get the hollow joy of making sure they don't steal the spotlight without doing something as annoying and forced as coming up with a lame excuse for them to just not be around.
I really miss actually playing Khalid Al Ghurab, Shadar-Kai Monk in Eberron, Inquisitive of Sharn, occasional pit fighter, Last War vet, and one time Arena slave in Droaam.
