You mean, stillborn? Lol.
However, it is true, but we should take into account it's the pokemon world. I will be discussing this as if this is real.. for the time being.
They are what? Ghost type pokemon. Now by ghost type pokemon, what does Nintendo mean? Do they mean, a) that the pokemon are ghosts(likely),b) that they look like ghosts and have a few characteristics of them, but are not "dead"?(also likely) c) or do they mean the pokemon are scared of ghosts?(very very unlikely)
Discuss, everyone else. Too tired to go into extra details ATM.
