the facts are a) a df doesnt exist twice in the same time.that means 1 df isnt recreated unless the one who ate it dies. b)there is a book with df pictures and names.a df cataloque.that means that df are very old and people know what a df ability is if it was eaten in the past.after the user dies the df is recreated.that means that someone might find mera mera no mi.and that gomu gomu no mi was eaten in the past,since shanks has seen the picture and knew the name. dont know what df roger had but it was recreated agter he died.
