So I was creating a page on Galaxia, Meta Knight's sword, and it hit me that the story the Anime gives is really wierd. I think that the whole "its a legendary sword" thing was a little crazy, expecially with Kirisakin and all. I can totally imagine Nightmare going, "Hey you! Kirisakin! Go get that sword thing and hide it in a cave and stay there!" I mean, what was the point of that? So the Star Warriors don't get it? Epic Fail, because Meta Knight got it, then Kirby defeated Kirisakin later with it. WOW.
I think just having it be Meta Knight's sword is perfectly fine, nothing special to it.
