guilty gear did it really well

bedman died in xrd, so people thought he wasn't going to return in the next game, but then they brought just the bed for strive

the lore implications are really sweet too, his wish to protect his little sister was so strong that, when he died, his mechanical bed inherited his will, so in a way he still keeps watch over her as a guardian angel (which is why the character is called "bedman?" with a question mark)
