Seriously, even though in some scenes that he's not really needed he's there like WTF and the fact that he always fights the final boss is just using his nakama power it's like Hiro is really Pushing Natsu forward :3 , *pukes rainbow*

Not sure what you meant by the question.

someone who seems to be in every scenes even they are really just a nuisance

I love Nagito Komaeda (Danganronpa) he's my favourite character in the whole series

Not sure why Asuna is here, she's pretty kick ass.

Um....I don't think you know what a Mary Sue/Gary Stu is.... It is someone is completely perfect, in life and in whatever they do. They hardly have any flaws, and the ones they do have just make them even more perfect. It isn't someone who just gets screen times....

@PumpkinQueen, well i did search the net so I thought a Mary Sue is a someone who is always appearing in the scene whether he/she is unnecessary

i mean like Natsu, he appeared on Erza and Jellal's battle in which I do (personally) believe that Erza alone could have defeated the guy, and when he fought brain/zero it's like Hiro made Jura's character laughable
