Deletion of Planet killer 2

Comment: This would only be taking this article from a borderline-unencyclopedic subject to a thoroughly unencyclopedic one. The proposed "list of planet killers" has no encyclopedic merit and it would be impossible to write an article on the list without using |original research. If this article would be kept, at the very least we should remove the entire "planet killer in fiction" section.  Nothing but |listcruft and original research in there

Comment: to List of planet killers in science fiction (or one of the names suggested above) and start a new article that's more like death ray. For the list, it'd help if the term "planet killer" is defined (using any |reliable sources). The chemical DDT or a doomsday device could be a "planet killer."  The term seems notable per what I see http://www.google.com/search?tbs=bks%3A1&tbo=1&q=%22Science+Fiction%22+%22planet+killer%22&btnG=Search+Books here
