Not strictly a myth, but Sinnoh Folk Story 1 says that if you eat every part of a water pokemon and then return the cleaned bones to the sea, the pokemon will "return, fully fleshed, and it begins anew". Obviously this could be interpreted as them just trying to discourage wasteful hunting, but its dubious wording also suggests that water pokemon may come back to life if venerated properly. That part's almost definitely full of shit
