alright thanks

If the bio is poorly written and doesn't make any sense, then I would say yes.

Of course this can be, if the univers doesn't feats with this. Example : a dead character who come back to life would be accepted on All dogs go to heaven source cause this already happen in the movie. But in a movie where there is no magic, this should be reported
After all, the story from our character has to be in the same univers than the movie.
