Natsu will kick the god slayers ass, haha but dont even think about him being able to defeat hades ^^ (at least not alone....) but before the fight with hades starts they have to beat many other hardcore enemies ... Will see how that death aura dude fits in the story, he might be the reason why the fight between the guilds will get interrupted and goes on later when the fairy tales achieved/upgraded new/their powers

hope you know what i mean....
